Potential Failures.
a. Ice on the “radiator” (Evaporator
).
Wrong parameter settings.
Too low air temperature. PCB defect.
b. Too little heating.
Energy loss from pool too big. Obstacles in front of the heat pump. Heat Pump installed inside a
shed. Recirculation of air trough the heat pump. “Radiator” is filled with leaves and dirt.
c. The heat pump stops.
(Error code EE3)
Too little water flow, Check Filter and filter Pump. Air in the Filter system. Water Flow Switch defect.
d. The heat pumps stops and starts frequently
Too little water flow. Air leakage in pipes on suction side. Check Filter and filter Pump. Air in the
Filter system. Water Flow Switch defect.
e. Heat pump does not work periodically
Weak power Supply. To long Supply Cable. Too small cable, Wrong Fuse
f. Problem to start the compressor
.
Starting / running Capacitor defect.
To low voltage
To thin Cable
