1 Heat pump operation 1.1 How a heat pump works Occasionally, particularly in low ambient operating conditions there can be a build up of frost on the external heat exchanger. This causes a fall off in efficiency and has to be removed. This is achieved by the control operating the change over valve(1) causing it to move to the defrost position.
Insulation and protection for the external pipework. Suitable and sufficient glycol mix to ensure frost protection in low temperatures. Heat pump Instructions and warranty documents pack Filter Drain plug Drainage elbow Batteries for controller Envirosorb 8 & 10 Diagram 4.1...

In order to guarantee the life span of all the appliance components and to keep the appliance in a good state of repair, only Glow-worm replacement parts should used when carrying out repair and maintenance works. Only use Glow-worm replacements parts.
14 Servicing IMPORTANT Any work carried out on the appliance circuit must be conducted by a competent person. 14.1 Annual maintenance/service Check that the safety components are working properly. Check the heating circuit pressure. Check the watertightness of the heating circuit, repair any leaks as necessary.
