Please read this manual carefully before installing the product, otherwise, you could damage the chiller, injure
users, or incur financial losses.
As advances in science and technology are made, the product will also improve. We would, therefore, urge you
to keep up to date with the latest products.
If you require further technical information, please contact your local distributor.
A. Before installing the chiller, check that your local power supply meets the requirements of the chiller. For full
details, check the unit's label or the performance information that appears in this manual.
B. Fit the electrical protection devices in compliance with local regulations.
C. You must ground the chiller to prevent electric shocks caused by an unexpected short circuit in the unit.
D. There is a wiring diagram in this manual.
E. For safety reasons, you should not replace or repair the chiller yourself. If repairs are required, please contact
your local distributor for assistance.
F. Do not place objects inside the chiller while it is working. They could come into contact with the fan and
damage it, as well as cause accidents (especially in the case of children).
G. Do not use the chiller without the grille or plaque, as this could cause accidents or the unit to malfunction.
H. If the unit fills with water, contact your local distributor immediately.
I. The unit may only be reset following a full inspection by a qualified service engineer.
J. Unqualified service engineers may not adjust the unit's switchboards, valves, or controllers.
* This appliance can be used by children aged 8 years and above and persons with reduced physical, sensory,
or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction
concerning the use of the appliance in a safe way and understand the hazards involved.
• Children shall not play with the appliance.
• Cleaning and user maintenance shall not be made by children without supervision.

Performance and installation
Performance and features:
The heat exchanger is made of PVC & titanium tubes, which can withstand and prolong exposure to pool
water.
The unit is very easy to operate; simply switch it on and set the desired pool water temperature. The system
includes a microcomputer controller, allowing all operation parameters to be set. Operation status can be
displayed on the controller with an LED display.

The unit will perform well in any location provided three factors are present:
1. Fresh Air - 2. Electricity - 3. Pool Filter Piping
The unit may be installed virtually anywhere outdoors, providing minimum distance requirements are met with
respect to other objects (see diagram below). For indoor pools, please consult your installer. Attention: Do not
place the unit in an enclosed area with limited air volume where the unit's discharged air will be recirculated, or
near shrubs that could block the air inlet. These locations deny the unit a continuous fresh air supply, which
reduces its efficiency and may prevent adequate heat yield. See diagram below for minimum required
distances.

(Note: When starting the cold water bathtub, the water pump switch must be turned on first, and then the

• Do not put your hands or any other object into the air outlet and fan. It could damage the chiller and cause
injuries.
• In case any abnormalities are found in the chiller, please cut off the power immediately and contact a
professional technician.
• It is strongly suggested to place a guard around the machine to keep children away from the chiller.

First time start-up
Note: In order for the unit to cool the pool (or spa), the filter pump must be running so that the water can
circulate through the chiller. Without this circulation, the chiller will not start.
When all connections have been made and checked, the following steps should be followed:
1. Turn on the filter pump. Check for leaks.
2. Turn on the electrical power supply to the unit, then press the ON/OFF key on the electronic control panel. The
unit should start when the time delay period has elapsed.
3. When the unit has been running for a couple of minutes, check if the air leaving the unit is hotter than the
ambient temperature.
4. Check the performance of the flow switch as follows: with the unit running, turn the filter pump off. The unit
should also switch off automatically.
5. The unit and the filter pump should run 24 hours a day until the desired pool water temperature has been
reached. Once the set temperature is reached, the unit will switch itself off. As long as the filter pump is running,
the unit will restart automatically when the temperature of the pool water rises more than 1°C below the set
temperature.
Depending on the starting temperature of the pool water and the air temperature, it can take several days for
the water to reach the desired temperature. Covering the pool can drastically reduce this period.

Maintenance and inspection
√ Check the water inlet and drainage often. The water and air inflow into the system should be sufficient so
that its performance and reliability are not compromised. You should clean the pool filter regularly to avoid
damage to the unit caused by clogging of the filter.
√ The area around the unit should be spacious and well-ventilated. Clean the sides of the chiller regularly to
maintain good heat exchange and to save energy.
√ Check if all processes in the unit are operational and pay special attention to the operation pressure of the
refrigerant system.
√ Check the power supply and cable connections regularly. Should the unit begin to function abnormally or
should you notice a smell from an electrical component, arrange for timely repair or replacement.
√ You should also purge the water if the unit will not work for an extended period of time. You should check all
parts of the unit thoroughly and completely fill the system with water before turning it on again afterward.

Troubleshooting guide
Incorrect installation may result in an electrical charge that could lead to the death or serious injury of users,
installers, or others by electrical shock, and it may also cause damage to the chiller. DO NOT attempt to
modify the internal configuration of the chiller.
• Keep your hands and hair clear of the fan blades to avoid injury.
• If you are not familiar with your pool filtration system and chiller:
• Do not attempt to carry out any adjustments or service without consulting your dealer, pool
professional, or air conditioning contractor.
• Read the entire installation manual before attempting to use, service, or make adjustments to the
unit.
• Wait for 24 hours after the installation before starting the chiller to prevent damage to the
compressor. (If the chiller has been transported and carried with the feet down all the time, it can be
started immediately).
Note: Switch off the power before carrying out any maintenance or repairs.
IMPORTANT REMARK: If a malfunction cannot be resolved immediately, in order to analyze the problem, we will
need to know the error code that is showing on the display controller as well as the values for the settings. We
also need to know the status of the chiller: the ambient temperature, water inlet/outlet temperature, if cold air
is coming out from the chiller, if the grill (evaporator) is cold or if there is ice on the chiller. Please keep this
information at hand when calling customer service and describe the issue.
