Compact Heat Pump Operating Instructions
Prior to use : -
1 Turn off the power supply at the local isolator
2 Open the door, using a coin or similar tool to unlock it
3 Check that the ground pressure gauge reads at least 0.3 bar. If the pressure is lower than this, open the mains cold water supply valve (fitted outside the case) fully until the gauge reads at least 1.8 bar, at which point a “click”will be heard. Close the mains cold water supply valve fully. If you can’t find this valve, or when you open it the gauge reading does not increase, call your installer and ask them about the mains cold water supply valve on the slinky ground array circuit.
4 Check that the underfloor pressure gauge reads at least 0.3 bar. If the pressure is lower than this, find the mains cold water supply valve, which is probably near your underfloor heating manifold fully until the gauge reads at least 1.8 bar, at which point a “click”will be heard. Close the mains cold water supply valve fully. If you can’t find this valve, or when you open it the gauge reading does not increase, call your installer and ask them about the mains cold water supply valve on the underfloor circuit.
5 Replace the door, using a coin or similar tool to lock it.
6 Turn on the power supply at the local isolator and program the external timeclock / thermostat to use as much off-peak electricity as possible.
7 NB. There is a delay of approximately 3 minutes before the Compact's refrigeration compressor starts.
