6.4 Filling the system
6.4.1 Filling the system
Caution
The heating circuit must have a sufficient water flow to operate
the heat pump. Insufficient or no hot water flow can lead to high
pressure failures in heating mode and low pressure failures in
defrost mode. If this happens, the system will be switched off by
either the high pressure limiter or the low pressure limiter.
Wrong settings on the controller can have a similar effect.
When filling the hydraulic system, please make sure the water
temperature in the system is above 10°C, and the ambient
temperature is above 0°C. The machine will not start when the
water in the system is under 10°C to protect itself.
Important
Failures in the heat pump are mostly caused by hydraulic
operation conditions and lack of water flow over the condenser. If
a malfunction is displayed, it is often to protect the heat pump. It is
generally not a sign of a defective heat pump.
