7 ROUTINE INSPECTION
Alpha SolarSmart 90 - Routine Inspection
To ensure efficient operation of the SolarSmart system, it is recommended that it is inspected and checked as necessary
at regular intervals.
Warning:
Before removing any covers or working on the system, isolate the electrical supply.
The data badge for the cylinder is located on top of the front housing underneath the top cover.
Always carry out electrical system checks, i.e. earth continuity, resistance to earth, short circuit and polarity with a
suitable meter, after any electrical work has been carried out on the system.

IMPORTANT NOTES FOR ROUTINE INSPECTION
1.
Run the system and check the operation.
2.
Ensure that all system connections and fittings are sound. Remake any joints and check the tightness of any fittings that
may be leaking.
3.
Inspect and clean, if required, the filter and cartridge in the pressure reducing valve and cartridge in the expansion relief
valve fitted to the unvented kit.
4.
Check the operation of the expansion relief valve by turning the head anti-clockwise until it clicks. The click is the valve
lifting off its seat allowing water to escape to the discharge pipe - check that this is happening and that the valve is not
leaking after it has been operated,
5.
Check the charge in the domestic hot water expansion vessel and re-pressurise, if necessary.
Note:
Only check the expansion vessel charge when the
system
pressure is zero.
6.
Record details of the inspection in the Inspection History Section 11.
