Put the heat pump on a at, solid base. Tilting the heat pump for max 3° is allowed.
Install silent blocks in order to avoid vibrations and noise.
All feeding of water treatment to the pool water has to be done downstream of the heat pump (2).
It is normal for condens water to come out of the heat pump. This is not a leak or fault with the unit. If the
humidity is very high, the condens water could be a number of liters a day.
Always keep the heat pump in upright position. If the unit has been tilted, then wait 24h before starting the
heat pump.
It is recommended to install a by-pass for easy maintenance.
2. Preparing the heat pump for use
2.1 Typical set-up
The factory provides the heat pump, Condens ux, connection kit and winter cover. Other parts,
including a contingent by-pass must be provided by the user or installer. The heat pump should be
located maximum 7,5m (1) away from the swimming pool. The longer the distance from the pool,
the greater the heat loss from the piping.

2.3 Electrical wiring
Connect the electrical wires using the following steps.
Step 1: Remove display. Step 2: Unscrew blue front housing.
Step 3: Snap off blue front housing Step 4: Remove ow sensor
Step 5: Remove transparent cover.
Step 6: Insert the electrical cable at the bottom of the heat pump (1). Make electrical connection with
heat pump’s terminal block (2).
Please turn off lter pump. Flow must be stopped before disconnecting ow sensor. Drain the water out of
the condensor to prevent water loss.

temperature is reached. The heat pump will start
automatically when the water temperature drops
below set point.
Low air temperature:
The heat pump stops
working and will restart
automatically when the
ambient temperature is
above -10°C.
Set:
Press to change the heat
pump settings. Please nd
more information about the
parameter interface in full
version.
Flow bar:
Indicates the amount of ow
going through the heat pump.
High air temperature:
The ambient
temperature is above
40°C. The heat pump
keeps on working but
without fan. As soon as
the temperature drops
below 40°C the fan
restarts.
The ambient
temperature is above
50°C. The heat pump will
not use the compressor
and fan to protect control
components. As soon
as the temperature
drops below 50°C the
compressor restarts.
Low ow:
The heat pumps stops working. The
amount of ow going through the heat
pump is too low. The heat pump will
restart automatically when the ow is
restored.
Heating:
Highlights when the heat
pump is heating.
Defrosting:
Highlights when a special ice-melting
program is active in the heat pump.
Heating mode will continue when the
amount of ice upon the evaporator is
reduced.
Set:
Highlights when the heat pump is unlocked.
Meaning the heat pump desired temperature or
parameters can be changed.
Display lock: The display shows when there’s no interaction for 5min. Press any button
for 3 seconds to unlock the display.

3.3 Parameter interface
Parameters can be set by a qualied person in order to make the heat pump more efcient
depending on the specic conditions of the swimming pool.
User editable parameter may be changed by the end user.
Installer editable parameters and factory settings may only be changed in a service center or by
similar qualied persons in order to avoid a hazard.

3.4 Error interface
When an issue is deteced the heat pump will try to solve it by analyzing several parameters,
restarting components and bypassing electronics. An error is shown on the display when the
program can not solve the issue.
Please contact your service centre or similarly qualied persons when an error occurs.
Err:
Notication of error.
Every 5 second the ERR

4. Maintenance and Inspection
- Check the water inlet and drainage often. The water and air inow into the system should be
sufcient so that its performance and reliability does not get compromised. You should clean the
pool lter regularly to avoid damage to the unit caused by clogging of the lter.
- The area around the unit should be spacious and well ventilated as shown in section 2.2. Clean the
sides of the heat pump regularly to maintain good heat exchange and to save energy.
- Check if all processes in the unit are operational.
- 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 ll the system with water before
turning it on again afterwards.
If your heat pump has been stored for a long time, perform the following steps when re-starting the
system:
1. Inspect the system for any debris or damage to the case.
2. Clean the evaporator ns with a soft cloth if necessary. Make sure the evaporator ns are clean.
Blocking the air intake will cause insufcient operation and will result in lower production of heat.
3. Check the fan for blockages.
4. Connect the water inlet and outlet.
5. Turn on the pool water circulation pump to start the water ow to the heat pump.
6. Restore electrical power to the heat pump and press the reset button on the RCD.
5. Service
If you need service or information or if you have a problem, please contact your local dealer. If
needed they will contact the manufacturer to solve your problem.
They are gladly willing to assist you!
