Check Valves
Check valves will not operate satisfactorily if
deposits form on seats or if seats become damaged.
Hot water or steam entering cold supply or vice versa
indicates service is necessary.
To service check valves, first isolate supplies.
Remove cap (196 06). Clean seat using a proprietary
scale solvent. Slight damage to seats can usually be
lapped out, otherwise check valve must be replaced.
Examine clack assembly (909 06) or 909 10) and if
damaged replace.
Check cap gasket (634 31) is in good condition.
Should you experience a problem not covered by
these instructions, our advice should be sought.
Re-Assembling
8.
If liner removed, smear '0' seals with petroleum
jelly to assist entry of liner into base. It will
probably be necessary to tap liner into position
using soft faced mallet.
9.
Re-assemble thermostat assembly into cover
and tighten stop plate screws but do not over
tighten.
10. Check cover joint (1152 002) is in position, then
re-assemble cover to base, ensuring lug of
thermostat assembly actuator engages in slot at
top of port sleeve. Refit cover screws.
11. Reset maximum temperature as earlier
described.
