Operation and maintenance
When the installation contractor installs your new heat pump, you should together with
the contractor check that the system is satisfactorily set up. Ensure the installation cont-
ractor demonstrates the switches, controls and fuses, so you know how the system works
and how it should be operated. Bleed the radiators after around three days of operation
and top up with water if required.
Boiler and radiator system safety valves
Around four times a year, check valve function through manually turning the operation
levers. Check that water runs from the waste line.
Mixing valve
The mixing valve valve is operated automatically from the control system and ensu-
res that the radiators achieve the correct temperature, independent of season. You
can however, where a fault occurs, operate the valve through pulling out the wheel on
the motor in and turning it clockwise to reduce the temperature or anticlockwise to
increase the temperature.
Drainage
The heat pump should be disconnected from the power source when it is being drai-
ned.
The drainage valve is positioned at the bottom left of the unit when viewed from the
front, behind the front of the heat pump. When draining the
whole
system, the mixing
valve valve should be fully open, i.e. turned anticlockwise as far as it will go. Air must be
supplied to closed systems.
Operation stops
The heat pump is shut down using the operating switch. If there is a risk that the water
can freeze, all water should be drained from the boiler and the
radiator system. The hot water circuit, which contains around
five litres, is emptied by inserting a hose at the bottom of the cold
water connection and then draining out by siphoning.
