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. Ideal Boilers 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 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 with
the pressure on the water side at zero (gauge pressure).
9. Check and advise the householder not to place any clothing or other combustible
materials against or on top of this appliance.
10. On completion of the work, ll in the Benchmark Service Record towards the back
of this manual.
After servicing, complete the relevant Service Interval Record section of the Benchmark
Checklist located on the inside back pages of this document.
IMPORTANT NOTE
When draining down the appliance for any reason, the instructions
provided in the Commissioning Section (Page 16) MUST be followed to
