ELECTRICAL CONNECTIONS

1. Shut off electrical power at fuse box before making any
connections. All wiring must comply with local codes.
2. Line voltage: Connect power cord to line voltage specified
on motor and nameplate. Power cord must be connected to
constant source of power (not a fan or other device
a
that
runs intermittently). If power cord does not have a plug,
wiring is as follows: green (or green/yellow) — ground; black
(or brown) — line; white (or blue) — neutral.
3. Safety switch: The safety overflow switch should be con-
nected to a Class II low voltage circuit. To control a thermo-
static circuit the COM and NO connections from the safety
switch are to be wired in series with the low voltage thermo-
stat circuit to shut down the heating/AC circuit. The COM
and NC switch contacts may be used to actuate a low volt-
age alarm circuit (connected in series) if the heating/cooling
system cannot be disrupted. The safety switch comes from
the factory with leads connected to the COM and NO switch
terminals. Typical hook-up of NC circuits would be (Figures
2 and 3).
1. Run flexible tubing or pipe from evaporator drain into one of
the three pump inlets. Be sure inlet piping is sloped downward
to allow gravity flow (Figure 4). Extend the inlet piping into the
tank from 1 to 3 inches to ensure that it will not interfere with
proper float operation. Be sure that the inlet piping is cut at an
angle where it enters the tank.
2. The outlet piping should be flexible tubing secured with a hose
clamp (not provided) or pipe (3/8" I.D. maximum to prevent
excessive flow back to unit). From condensate unit, extend
discharge piping straight up as high as necessary. Do not
extend this line above the head/GPH of the particular model
being installed. From this high point, slope discharge line
down slightly to a point above drain area; then turn down and
extend to a point below or approximately level with the bottom
of the condensate unit. This will give a siphoning effect which
will improve efficiency of the condensate unit and will, in most
cases, eliminate the need for a check valve (Figure 5). If it is
not possible to slope discharge line down, make an inverted
"U" trap directly above the pump at the highest point.

SERVICE INSTRUCTIONS
1. Make certain that the unit is disconnected from the power source
before attempting to service or remove any component.
2. Be sure the floats move freely. Clean as necessary (Figure 6).
3. Clean the tank with warm water and mild soap.
4. Check the inlet and outlet piping. Clean as necessary. Be sure
there are no kinks in the line that would inhibit flow.
TESTING
1. Turn on power.
2. Remove motor/tank cover assembly and hold level.
3. Test motor switch by raising motor switch float with finger
(Figure 6). Motor should turn on just before float contacts
cover.
4. Test safety switch by raising safety switch float with finger.
Safety switch should activate before float contacts cover.
5. Replace motor/tank cover assembly on tank.
This pump is suitable for gas furnace condensate applications.
Caution must be taken to ensure acidity of condensate does not
increase below the average pH of 3.4 (to prevent localized pocket
of acid that acts like a battery causing pitting) by routinely cleaning
or flushing tank with fresh water.
