Health & Safety Warnings for the User

A risk factor is hypothermia. This occurs when you suffer a drop in core body temperature and can eventually lead to loss of consciousness and heart failure.

The amount of time you can spend in cold water without suffering from hypothermia is determined by the water temperature, your body size and shape, your level of cold adaptation and your experience, among other factors. Check with your doctor as relevant. Start with safe, short dips of 30 seconds to learn what your limits are. If you begin to feel uncomfortable or you start to shiver, listen to your body, get out and slowly warm up by walking around.

If you like, you can check the water temperature before entering the bath, to ensure that it is at a temperature that is suitable for your experience in cold exposure. The temperature of the water is displayed as default on the control panel.

Children must be supervised near your Pro Plunge Lite to make sure they do not play with the equipment and do not carry out operations to be performed by adults (cleaning cycles/maintenance). Always attach the cover when not in use. Children are not advised to use the Pro Plunge Lite.

Please check with your doctor as relevant. Pregnant women should talk to a doctor first, low temperatures are not advised. Anybody under medical care, such as people with heart conditions, diabetes, high or low blood pressure or other health problems must not use your Pro Plunge Lite without first consulting their doctor. People with infectious diseases should not use your Pro Plunge Lite without first consulting their doctor.

Position & Operation

Before installing the Pro Plunge Lite, please ensure that there are no obstacles on the outside of the vents on the side of the chiller/fan. We recommend a 2 ft space around the chiller for the best ventilation.

If there are obstacles blocking the vents, it will cause the compressor to self-protect and your Pro Plunge Lite water temperature cannot drop. Once your Pro Plunge Lite is in a position you are happy with please leave it laid flat for 24 hours for the refrigerant to settle in the compressor (Pro Plunge Lite units are the same as a fridge or freezers and the gas needs to settle before use).

Your Pro Plunge Lite can then be filled with water but it should not be turned on for 24 hours. We do recommend that you read the full manual though in particular the safety information before you use.

Clearance: Maintain a 600mm (60cm/ 2 ft) clearance around your Pro Plunge Lite for optimal air circulation. Avoid placing the unit in enclosed spaces to ensure efficient heat dissipation this will also help prevent condensation.

Circulation and Fan Operation: Ensure the unit is in a well-ventilated area.

Power connection 1. Your Pro Plunge Lite must be plugged directly into an RCD protected circuit on a 13-amp socket or box. 2. Do not use an extension cable to run the Pro Plunge Lite, this can be a fire hazard. 3. Please ensure that the socket is 1-2 metres away from the Pro Plunge Lite. If this is not possible you must convert your plug socket to a waterproof socket.

To fill your Pro Plunge Lite for the first time 1. Turn off the power to your Pro Plunge Lite before filling/draining and do not turn the power back on until your Pro Plunge Lite has been refilled. 2. Fill your Pro Plunge Lite to the desired level. It will take approximately 15-30 minutes to fill, depending on water pressure. 3. Open the air bleed screw to exhaust air from the filter and pump housing. 4. Switch the power on only when it has been filled. The monitor will flash green, wait for 3-5 mins and it will enter the running state. The default temperature is 3 degrees. 5. Allow your Pro Plunge Lite to get down to the temperature as set on your temperature controller. As your Pro Plunge Lite is affected by the environment please turn the machine on 6-12 hours in advance.

If your Pro Plunge Lite is set to 3 degrees, it will run the chiller until it reaches this temperature. Once the temperature then reaches 4 degrees it will turn the chiller on and cool to 3 degrees.

Where multiple users are using your Pro Plunge Lite frequently we recommend adding a Pro Plunge Lite Sanitiser. This is what we recommend as a proven, safe and powerful residual disinfection for Pro Plunge Lite units. We do not recommend chlorine products or other salts.

To drain and refill the Pro Plunge Lite: 1. Turn off the power to the Pro Plunge Lite. 2. Drain the water using the hose pipe attachment to connect a hose pipe and then open the ball valve to let the water out. 3. Wipe out the inside of your Pro Plunge Lite with a clean cloth to clean any residual dirt or grime. DO NOT use any chemicals such as bathroom cleaner or stainless-steel cleaner. 4. When it is clean and rinsed, ensure the ball valve is closed. Re-fill using a hose pipe. 5. Switch the power back on to your Pro Plunge Lite and allow the water to get down to the temperature as set by your controller.

System Protection

Water Flow Monitoring and Recovery System

Upon initiating the water pump for a duration of 10 seconds, the detection of a disconnected water flow switch for 2 consecutive seconds results in the identification of a water flow fault, prompting an immediate shutdown of the entire machine as a safety measure.

In the event of a water flow fault, the system is designed for automatic recovery. Notably, this fault is not suppressed during defrosting periods. The recovery process involves the automatic cycling and activation of the water pump, continuously monitoring and awaiting closure of the water flow switch. This cycle repeats every 2 minutes and 30 seconds until the switch is successfully closed.

To indicate the occurrence of this fault, the remote control interface will display the code FFF, notifying users of the issue.

Water Flow Fault

After running the water pump for 10 seconds, if the water flow switch is detected to be disconnected for 2 consecutive seconds, it will be a water flow fault and the entire machine is shut down.

After a water flow fault occurs, it can automatically recover. Please do not shield this fault during defrosting. After a water flow fault occurs, the water pump automatically cycles on starts, detects the water flow switch until it is closed. Cycle every 2 minutes and 30 seconds.

The remote control will display FFF.

Winter Antifreeze Protection

Detect the inlet temperature Tin and ambient temperature Tx in standby mode

When Tin < 15°C and Tx ≤ 0°C, enter the first level antifreeze state, and the unit will automatically start and operate the water pump mode; when Tin ≥ 15°C or Tx ≥ 2°C, exit the antifreeze process.

If Tin ≤ 2°C and Tx ≤ 0°C, enter the second level antifreeze state, and the unit will automatically start and operate in heating mode; until Tin ≥ 15°C or Tx ≥ 2°C exit the antifreeze process.

If Tx malfunctions, it is up to Tin to decide whether to prevent freezing. If Tin malfunctions, Tx decides whether to prevent freezing (Tin malfunctions can only enter first level antifreeze). If both Tin and Tx malfunctions, the antifreeze function will not be processed.

The remote control will display AFP.

Water Inlet Temperature Sensor Fault Detection

The detection of a short circuit or open circuit in the water inlet temperature sensor is identified as a fault in the sensor itself. Specifically, labeled as a water inlet temperature sensor fault. This triggers an automatic shutdown of the system as a protective measure.

The remote control will promptly indicate this issue with the identifier PP 1.

Discharge Temperature Sensor Fault Detection

Detection of a short circuit or open circuit in the discharge temperature sensor is recognized as a fault in the sensor, termed as a discharge temperature sensor fault. This initiates an immediate system shutdown as a safety precaution.

The remote control will display the specific fault using the code PP 2 to notify users of this issue.

Coil Temperature Sensor Fault

Detection of a short circuit or open circuit in the coil temperature sensor is recognized as a fault in the sensor itself, referred to as a coil temperature sensor fault.

In the event of this fault, the remote control will display the identifier PP 3 to indicate the specific issue.

Fault Detection: Ambient Temperature Sensor

Detection of a short circuit or open circuit in the ambient temperature sensor is identified as a fault in the sensor itself. Consequently, the antifreeze conditions associated with this are canceled, allowing the system to resume normal operation.

When this fault is detected, the remote control will indicate the issue with the code PP 5.

Low Pressure Protection

Following the system compressor's initial five minutes of operation, if the system's low-pressure switch is identified as disconnected for 10 consecutive seconds, it triggers the activation of low-pressure protection.

Exiting the low-pressure protection mode occurs upon detecting the closure of the low-pressure switch. However, if this fault recurs three times within 30 minutes, restoration becomes contingent on a power-off reset.

Notably, this fault is exempted during defrosting periods.

The remote control interface will indicate the occurrence of this issue with the code EE 2.

If this issue occurs three times within a span of 30 minutes, a power-off reset becomes necessary for restoration.

The remote control will also display EE5 when this protection mechanism triggers.

High Discharge Temperature Protection

Once the compressor has been running for one minute, if the discharge temperature exceeds or equals 95°C (adjustable parameter P09), it signifies an overheating issue.

As a safety measure, the machine will halt, indicating an EE5 error on display. If the discharge temperature drops to 80°C or 15 degrees less than the peak, normal display resumes, and the high discharge temperature protection deactivates.

The compressor includes a 3-minute shutdown safeguard.

Communication Failure

In the event that the motherboard fails to receive any communication signal from the remote controller within the first 20 seconds after initial power-up, it is regarded as disconnected from the remote controller. During this period, the system operates solely based on the mode switch signal without displaying any indication of disconnection.

Alternatively, if the motherboard remains connected to a remote controller but fails to transmit its status signal for 10 consecutive seconds, it is identified as a communication fault.

The occurrence of this communication fault is signaled by the remote control displaying EE 6.

Maintenance & Cleaning

Maintaining your Pro Plunge Lite keeps it clean and hygienic, while also protecting it from damage.

If you want to keep it clean, you should combine both prevention and treatment to protect it. It has a built-in Ozone and filter system for clear water.

How to change the filter

When replacing the filter element, please close the water inlet and outlet valves of the tub, loosen the filter exhaust valve by counterclockwise, then unscrew the filter cover, remove the filter element, and replace the filter element.

Hand replacing the white filter cover on the unit

After replacing the filter, screw on the filter cover, open the ball valves. Then open the exhaust valve slightly to ensure there are no air locks. After this, you can turn the Pro Plunge Lite back on.

Filter clean and change

The filter should be replaced every three months. We recommend that you clean the filter every 1-2 weeks depending on usage. We recommend your Pro Plunge Lite filter.

Turn off your Pro Plunge Lite before cleaning or changing the filter.

Stainless Steel Maintenance

Cleaning Methods

If regular routines are adopted, the cleaning of stainless steel is relatively easy.

Where however, the steel shows severe signs of surface discoloration (perhaps following periods of neglect, or misuse), the following cleaning methods should be applied.

Always attempt the mildest cleaning method first. Be patient and repeat it a fair number of times before resorting to more severe cleaning techniques.

Light Stains:

Light, superficial brown staining can be removed by routine cleaning as above, repeated as necessary.

Moderate Stains:

In case of moderate soiling, repeat the routine cleaning above or use a mild (non-scratch) household caustic cream-cleaner with a fine nylon scouring pad.

Rub the surface as softly as possible using long even strokes in the direction of the polish line. Avoid using a circular rubbing action. Rinse and follow by routine cleaning as above.

If this does not suffice, final resort may have to be made to the use of a coarser nylon scouring pad, but with the risk that the surface may become slightly affected.

Test for effect on a small area before proceeding with other areas.

Persistent Stains:

Persistent stains indicate an inherent or recurring problem, which if not addressed on a timely basis, could become progressively troublesome.

For example, a small rust spot with a halo around it indicates a fragment of carbon steel has been inadvertently embedded in the surface of the stainless steel.

Dab the spot with a cotton bud soaked in a 10% solution of nitric acid, keeping it moist for 20-30 minutes.

Repeat this treatment until the spot does not recur.

Severe rust stains may be removed by swabbing with a 10% solution of nitric acid for 15-20 minutes, repeating as necessary.

Very severe stains may require hard rubbing with a paste of fine household abrasive and 10% nitric acid, using a coarse nylon scouring pad.

All acid treatments, however, must be followed by a neutralizing rinse with calcium bicarbonate solution.

Note: Nitric acid (HNO₃) is friendly towards stainless steel and a 10% solution (1-part nitric acid added to 9 parts water) is usually used.

Caution: Concentrated nitric acid must be handled with care, 10% solutions are less hazardous nevertheless, it is advisable to wear rubber gloves and eye protection. If accidental skin contact occurs, wash well with lots of water. Keep it out of reach of children, etc.

Consult the Material Safety Data Sheet for details.

Scouring Pads

3M manufacture a range of nylon non-woven, fine, multi-purpose, and heavy-duty scouring pads under the trade name Scotch-Brite.

Check product suitability for its intended use with your retailer.

Soft nylon scouring pads should be adequate for dealing with most deposits.

Cleaning Schedules

If care is taken during installation, cleaning before 'hand-over' should not present any problems.

More attention, however, may be required if the installation period has been prolonged or hand-over delayed.

Following hand-over, the frequency of cleaning is dependent on the application - a simple rule is:

Clean the metal when it shows signs of staining to restore its original appearance.
