Servicing
n
Before disassembling valve piping, turn off valve and the supply
water upstream.
1. Remove four bonnet screws and pull out bonnet assembly.
The motor should come out with the bonnet. If not, it can eas-
ily be pulled out.
2. Remove the cartridge
3. Reassemble the valve in reverse order.
IMPORTANT: After completing any maintenance/repairs, check
maximum discharge temperature. Adjust if necessary.
4. Maximum temperature setting: The high temperature limit
stop is threaded on to the bonnet and is turned counter clock-
wise for an increased setting and clockwise for a decreased
setting. Powers recommends a maximum setting of 110°F
(43°C). To adjust the temperature, rotate stem to the maximum
desired outlet temperature, screw temperature limit stop until
it touches stem’s shoulder. Close valve and open it to verify
setting.
