3. Safety switch: The safety overflow switch should be connected to a Class-
II low voltage circuit. To control a thermostatic circuit the COM and NO
connections from the safety switch are to be wired in series with the low
voltage thermostat circuit to shut down the heating/AC circuit. The COM
and NC switch contacts may be used to actuate a low-voltage alarm circuit
(connected in series) if the heating/cooling system can not be disrupted.
The safety switch comes from the factory with leads connected to the COM
and NO switch terminals.
NOTE: When installing or replacing the safety switch, make sure that it is
positioned between the two ribs on the motor cover (Figure 5).
For hook-up of NC circuits see Figure 5.
4. If fused plug is used on 230V units, a 1.0 amp fuse is recommended.

1. Run an inlet line (flexible tubing or pipe) from the evaporator drain into one
of the three drain holes, ensuring that the line is sloped downward to allow
gravity flow. Cut the inlet line at an angle where it will enter the tank, then
put the line into the tank 1 to 2 inches to ensure that it will not interfere with
proper float operation.
2. The discharge line (Figure 6) should be flexible tubing secured with a hose
clamp (not provided) or pipe (3/8 inch I.D. maximum to prevent excessive
flow back to unit). From the pump, extend the discharge line straight up as
high as necessary (but not above the head/GPH of the pump). From this
high point, slope the discharge line down slightly to a point above the drain,
then turn down and extend to a point below or approximately level with the
bottom of the pump. This will give a siphoning effect, which will improve
the efficiency of the pump and will, in most cases, eliminate the need for a
check valve. If it is not possible to slope the discharge line down, make an
inverted U-trap directly above the pump at the highest point.

SERVICE INSTRUCTIONS
Inspect and service the pump at least once a year.
NOTE: This pump is equipped with a ¼-turn check valve, which can be easily
disconnected from the pump during maintenance/cleaning. The discharge line (and the
condensate in the line) can remain while the check valve is unlocked and removed.
1. Disconnect the pump from the power source.
2. To access the tank, float, or intake screen for cleaning, lightly squeeze the
tank walls to release the latch (Figure 7), then grab and raise the motor
cover. (The motor cover hinges on the opposite end of the tank.)
3. Be sure the floats move freely. Clean as necessary.
4. Clean the tank with warm water and mild soap.
5. Check the inlet and discharge lines, cleaning as necessary. Be sure there
are no kinks in the lines that would inhibit flow.
6. Close the motor cover and reconnect the pump to the power source.
