MAINTENANCE
Regular maintenance
Check the water flow and valves regularly. Too little water or leakage will disrupt the operation of
the heat pump and can cause damage to the unit.
Check the pool filter regularly.
The area around the heat pump must be in order, clean and dry. Clean the pool heat pump
regularly.
Check the connections on the pool heat pump regularly.
Drain the water from the pool heat pump through the drainage opening at the bottom of the unit if
you do not intend to use it for a long period of time or if there is a risk of frost.
Operating problems
Note that when the temperature changes this significantly affects the capacity and efficiency of the heat
pump. Consequently, a perceived fault may be a misjudgement of the heat pump’s capacity and should
therefore not be seen as an operating problem. The pool heat pump must not be used when it is colder
than about 5 °C. Drain the water from the pump during the winter and store in an area free from frost. The
pool heat pump is designed to improve the comfort during the bathing season and to extend it during the
spring and autumn. The outdoor temperature and insulation are decisive for the temperature reached in
the pool.
The stated output for the pool heat pump applies at 27 °C. At lower outdoor temperatures the output will
be lower. The stated recommendations are based on industry standards and are an estimate based on
normal insulation and operating temperatures.
Error codes
Error codes are shown on the display to indicate a possible error. The unit stops and an error code is
shown. See the examples of error codes in the table below.
Error

Description
Cause
Action
PP 01
Faulty temperature sensor
by the water inlet.
The sensor is short
circuited or the circuit is
not closed.
Check the sensor with an ohmmeter.
Check the connections on the sensor.
PP 02
Faulty temperature sensor
by the water outlet.
The sensor is short
circuited or the circuit is
not closed.
Check the sensor with an ohmmeter.
Check the connections on the sensor.
PP 03
Faulty sensor on circuit 1
The sensor is short
circuited or the circuit is
not closed.
Check the sensor with an ohmmeter.
Check the connections on the sensor.
PP 04
Faulty sensor on circuit 2
The sensor is short
circuited or the circuit is
not closed.
Check the sensor with an ohmmeter.
Check the connections on the sensor.
PP 05
Faulty outdoor
temperature sensor.
The sensor is short
circuited or the circuit is
not closed.
Check the sensor with an ohmmeter.
Check the connections on the sensor.
PP 06
Too large difference
between the
incoming/outgoing water
The water flow is
insufficient.
Check the flow and that the unit is not
blocked.
