Saving energy
To reduce energy consumption and related costs, you can take the following measures:
• If you do not use the pool for a few days (e.g., on weekends), keep the current water
temperature approximately at the desired water temperature. The heat pump needs
time to heat up the pool water. If there is a large temperature difference between the
current water temperature and the desired water temperature, it can take several
days until the desired water temperature is reached.
• If do not use the pool for more than a week, shut off the heat pump or reduce the set
water temperature.
• Do not use the heat pump when the ambient temperature falls below 5 °C.
•
Cover the pool to prevent heat loss due to wind.

Operation
WARNING!
Risk of death when operating the water treatment system during bathing.
Hair or clothing might get sucked into the suction openings of the pool and in extreme cases
trap persons under water and prevent them from surfacing again.
-Never operate water treatment system devices while persons are in the pool.
-Prevent any access to the pool for as long as water treatment system devices are in use.
CAUTION!
Risk of injury!
A damaged device or damaged accessories may cause injuries.
-Check the device and the accessories (see section "Testing").
NOTICE!
Reduced or blocked ventilation of the heat pump can lead to faulty extraction of heat or
moisture. This might cause mold or overheating of the finned heat exchanger.
-Clean the grate in front of the fan impeller and the fins of the heat exchanger at regular
intervals and make sure that dirt such as leaves or similar does not get into the heat
exchanger.
-Make sure that the grate on the heat exchanger is never covered up and that the air can
circulate freely through the device.
RCD power plug
The RCD power plug consists of a safety plug and a residual current circuit breaker. The safety plug
must be connected to a matching socket with an earthed protective conductor. The residual current
circuit breaker disconnects the heat pump from the voltage as soon as unexpectedly high currents that
are dangerous for persons flow through the heat pump (e.g. short circuit through electroconductive parts
of the housing).

Activating heating
The adjustable temperature range in operating mode is between 15 to 35°C. The start value of the set
water temperature is 27°C.
The water in the pool is heated up fastest at maximum throughput of the water through
the heat pump (see section "Technical data"). However, increasing the flow rate reduces
the time spent at the heat exchanger, which means that the difference in temperature
between the water in the pool and the heated water at the pool inlet is lower overall and
therefore less noticeable. Please measure and record the change in the current water
temperature every 30 minutes to determine the actual heating of the pool water.

-Condensation water
-Pool water
- Refrigerant
Condensation water
Condensation water forming during operation is normal. There is no damage. The surface of the finned
heat exchanger gets cold, humidity in the ambient air condenses and, in extreme cases, freezes.
Condensation water collects in the bottom tray and is discharged through a hole and via the drain
connection piece
4
. If the drain connection piece
4
is plugged up, the condensation water cannot
drain from the heat pump and larger amounts collect in the heat pump.
Pool water
Leaking pool water indicates that:
•
the hose is not correctly installed on the adapter
2
.
•
the adapter
2
is not correctly connected to the heat pump
1
.
•
the seal in the adapter
2
is defective or missing.
•
the flow pipe inside the heat pump has a leak.

Refrigerant
Leaking refrigerant indicates that the refrigerant circuit in the finned heat exchanger has a leak. Contact
a qualified person immediately if you detect a leak in the refrigerant circuit.
Keep in mind that refrigerants are odorless.
Storage
As soon as the outside temperature permanently falls below +5 °C, the heat pump should be stored
away for the winter to prevent damage through ice formation (frost bursts).
Permanently installed water pipes do not necessarily have to be deinstalled. If the
location of the heat pump is protected against heavy soiling and strong weather
influences, it is sufficient to drain the water from the heat pump and the water pipes.
Shutdown in winter
1. Disconnect all lines and pipes (see section "Deinstallation").
2. Clean the heat pump thoroughly (see section "Cleaning").
3. After thorough drying, store the heat pump in a dry, frost-free place (>+5 °C).
The heat pump is stored away for the winter.

socket/extension cable.
Contact an authorized electrician.
The heat pump does not start. The heat exchanger has not
reached its operating
temperature yet.
Wait for 90 seconds after activation.
The current water temperature
is higher than or equal to the set
water temperature.
Set a higher temperature or wait until the
current water temperature drops below
the set water temperature.
The water in the swimming pool
does not reach the desired
temperature even though the heat
pump is running.
The operating time of the heat
pump was too short for it to
reach the set water temperature.
Wait for 24-48 hours.
Ice has formed on the finned heat
exchanger.
The ambient temperature is too
low/the humidity is too high.
Activate manual defrosting (see section
"Operation").
