Draining and refilling must only be carried out using new refrigerant (for the amount and type of refrigerant see manufacturer’s plate) through the service valves. All warranties from Thermia are void if, when filling with refrigerant other than Thermia Värme AB specified Caution refrigerant, if there has not been written notification that the new refrigerant is an approved replacement re- frigerant together with other remedies.
If the installation is only to be driven by the immersion heater during the installation, ensure that the heating Caution system is filled and the brine pump and compressor cannot be started. This is carried out by setting the oper- ating mode to AUX. HEATER. Thermia Värmepumpar VMGFP202...
