The Registered Installer is responsible for the safe installation and operation of the
system. The installer must also make his customer aware that periodic maintenance
of the equipment is essential for safety.
Maintenance periods will vary for many reasons. Gledhill Building Products Ltd
recommend a maximum of 12 months to coincide with boiler maintenance. Experience
of local water conditions may indicate that more frequent maintenance is desirable,
eg, when water is particularly hard, scale-forming or where the water supply contains
a high proportion of solids, eg, sand. Maintenance must include the following:
1. Check and clean fi lter
2. Manually check the operation of the temperature relief valve.
3. Manually check the operation of the expansion relief valve.
4. Check discharge pipes from temperature and expansion relief valves are free from
obstruction and blockage and are not passing any water.
5. Check the condition and if necessary descale the heat exchangers in hard water
areas.
6. Check that water pressure downstream of pressure reducing valve is within the
manufacturers limits.
7. Check operation of motorised valve.
8. Check the pressure on the air side of the expansion vessel. This must be done when
the volume in the cylinders is cold.
9. Check and advise the householder not to place any clothing or other combustible
materials against or on top of this appliance.
