2) Solenoid:
2.1) With the solenoid repositioned on the sleeve, slide washer over sleeve, replace
nut, and tighten nut with an input torque of 43-53 in-lbs.
NOTE:
Never apply electricity to a solenoid valve without ensuring that the
solenoid is properly installed on the valve sleeve. The resulting high in-
rush of current can result in an electrical short in the solenoid.
2.2) Rewire and connect valve power leads to 1TB5 (#7R) and 1TB2 (#2W4) for
normal operation. Refer to Electrical Schematic
Diagram 4
in
Section VII
.
2.3) Tighten conduit union to complete the installation.
5.
Check solenoid valves for valve water leakage.
a) External valve water leakage:
Open the closest shower station down stream of the Saf-T-Flo
. Perform a visual
inspection of both valves for water leakage.
b) Internal valve water leakage:
NOTE:
Refer to Electrical Schematic
Diagram 4
in
Section VII
.
1) Carefully open junction box cover while protecting the indicating light wiring. The
indicating light leads are wired to the terminal strip and must remain properly
connected to facilitate rapid maintenance.
2) In the junction box, bypass the flow switch 1-FLS by placing a temporary jumper
wire from TB1 to TB3. This will keep the 1-CR energized. Be sure to tag the
bypass/jumper for identification.
3) Disconnect 1-SOL power leads from terminal TB5 (#6R) and connect to TB1. The 1-
SOL valve should now be held CLOSED.
4) With both cold and hot water supplied to the Saf-T-Flo
, open the closest shower
station down stream of the Saf-T-Flo
. If water flow is present at the shower station,
valve water leakage has been determined.
5) Identify the failed solenoid valve:
2-SOL valve water leakage: If delivered water temperature is warm.
1-SOL valve water leakage: If delivered water temperature is cold.
6.
If solenoid valves(s) performed unsatisfactory and the failed valve(s) have been identified,
disassemble to inspect the internal valve components. Replace any damaged or worn
components. Follow instructions in
Section E.3
(for 1-SOL) and/or
Section E.4
(for 2-
SOL).
7.
If solenoid valves test to satisfaction, rewire for normal operation.
CAUTION CAUTION CAUTION
CARE MUST BE TAKEN WHEN OPENING JUNCTION BOX COVER TO PROTECT THE
INDICATING LIGHT WIRING INSIDE THE BOX AND TO AVOID ELECTRICAL SHOCK.
USE PIPE SEALANT SPARINGLY.
