Drain Solenoid Valve
1. Set the voltmeter to the 250 VAC scale.
2. Set the ON/OFF switch to the OFF position.
3. Set the TIMED/MANUAL switch to the TIMED position.
4. Check the drain solenoid ground wire (green) for continuity and secure
connections.
5. Disable the heater contactor by carefully pulling the black wire from the high
temperature limit switch.
6. Disable the condenser solenoid by carefully pulling the brown wire from the
condenser solenoid.
7. Set the ON/OFF switch to the ON position. Watch the outflow at the drain
opening, and the water level in the float assembly. The water level in the float
assembly corresponds to the water level in the generator.
• If water fills the generator and float cylinder, and
no water flows from drain
opening; continue this test with step 8.
• If water does not fin the generator and float cylinder, and water flows from
dram opening; continue this test with step 9.
8. Set the ON/OFF switch to the OFF position.
• If water flows from the drain, the drain solenoid is good.
a.
Reconnect the black wire to the high temperature limit switch.
b. Reconnect the brown wire to the condenser solenoid.
c. End this procedure here.
• If no water flows from the drain, the fault may not be in the drain solenoid.
a.
Reconnect the black wire to the high temperature limit switch.
b. Reconnect the brown wire to the condenser solenoid.
c. Check for dogged drain plumbing.
9. Refer to Figure 5-18, and connect the voltmeter leads to terminal 5 of relay K1
and the terminal of the condenser solenoid connected to the red wire. With these
connections, check for 120 VAC across the drain solenoid.
• If the meter reads 120 VAC across the dram solenoid, either the solenoid valve
or the wiring connected to it is faulty.
a. Check the red wires between relay K1, the drain solenoid valve, and the
condenser solenoid for continuity, and secure connections. Replace or repair
faulty wiring and connections. Perform steps c and d.
b. If the wiring and connections are good, the solenoid valve is faulty.
Replace the drain solenoid valve and perform steps c and d.
c.
Reconnect the black wire to the high temperature limit switch.
d. Reconnect the brown wire to the condenser solenoid.
