Do not use where the water level can exceed the ON level of the

pump.
Do not completely submerge the pump.
Do not use to pump flammable or explosive fluids such as gasoline,

fuel oil, kerosene, etc. Do not use in explosive atmospheres. Use

only with liquids compatible with pump component materials.
Do not handle the pump with wet hands or when standing on a wet

or damp surface, or in water.
This pump is supplied with a grounding conductor and/or ground-

ing type attachment plug. To reduce the risk of electric shock, con-

nect only to a properly-grounded, grounding-type receptacle.
In any installation where property damage and/or personal injury

might result from an inoperative or leaking pump due to power out-

ages, discharge line blockage, or any other reason, use a backup

system(s) and/or alarm.
Support the pump and its piping when assembling and when

installed. Failure to do so may cause piping to break, pump to fall,

motor bearing failures, etc.
This pump’s motor housing is filled with a dielectric oil for motor

heat transfer and lifetime lubrication of the bearings. This oil is

non-toxic. If oil escapes the housing, however, it can be removed

quickly by placing newspapers on the water surface to soak up

the oil.

INSTALLATION

WARNING

1. Carefully unpack the pump. A cardboard insert was installed to

prevent switch movement during shipment. Remove this insert

by carefully pulling it away from the pump.

NOTE:

The pump

will not operate with this insert in place.

2. 2-ABS and 3-ABS: Use the two holes in the reservoir to mount

the pump in a convenient location. Ensure that the pump is

level and that the inlet is below the coil drain.

3. Install a discharge line (flexible tubing or pipe) from the

evaporator drain into the pump reservoir, sloping the line

downward to allow gravity flow.

4. From the pump, extend the discharge line straight up as high

as necessary, but not above the head/GPH of the pump (Figure

1). From this high point, slope the discharge line down slightly

to a point above the drain area, then turn the line downward

and extend to a point below or approximately level with the

bottom of the pump. This will create a siphoning effect, which

will improve the efficiency of the pump. If it is not possible to

slope the discharge line downward, create an inverted “U” trap

directly above the pump at the highest point.

ELECTRICAL CONNECTIONS

WARNING

WARNING:

All wiring must comply with local, state, and national

electrical codes.
1. Shut off electrical power at the fuse box before making any

connections.

2. Connect the power cord to the line voltage specified on the

motor and nameplate. Connect the power cord ONLY to a

constant source of power (not a fan or other device than runs

intermittently). If the power cord does not have a plug, wiring is

as follows: green/yellow - ground, brown - line, blue - neutral.

TESTING

WARNING

1. Connect the pump to power.
2. Fill the reservoir with water and verify that the pump turns on.

Check the lines for leaks and kinks that will prevent full water

disposal.

If no water is available for testing, remove the switch screen,

insert the differentiator top into the switch housing bottom, and

verify that the pump comes on.

CAUTION:

Do not operate the pump dry for more than a few

seconds. Do not test this way if water is present.

NOTE:

The volute has a small air-bleed hole (near the top

screw) that helps prevent the pump from air locking. It is

normal for a small amount of water to run out of this hole during

operation.

SERVICING

WARNING

CAUTION:

DO NOT open the sealed portion of the pump or

remove housing screws.

NOTE:

This pump is permanently lubricated; oiling is not

required.
Periodic cleaning of the pump parts will prolong the life and

efficiency of the pump. Refer to the following steps:
1. Disconnect the pump from the power source.
2. Inspect the power cord to ensure that it is in good condition,

with no nicks or cuts.

NOTE:

The power cord cannot be

replaced. If it becomes damaged, the entire pump must be

replaced.

3. Check the float to ensure that it moves freely. Clean if neces-

sary.

4. Remove the three screws that secure the volute to the pump,

then remove the volute

5. Using a brush and penetrating oil, lightly clean any corrosion

or debris that may clog the impeller. Scrape away any encrust-

ed material, if necessary.

6.  Turn the impeller by hand, ensuring that it turns freely.
7.  Be sure the float moves freely. Clean as necessary.
8.  Connect the pump to the power source and ensure that the

impeller turns freely (see TESTING section).

CAUTION:

Do not

operate the pump dry for more than a few seconds.

9. Disconnect the pump from the power source.
10. Using the three volute screws, attach the volute to the pump.
11. Connect the pump to the power source and ensure that it oper-

ates properly.

12. If the pump does not operate properly, call your dealer for ser-

vice. DO NOT open the sealed portion of the pump or remove

screws other than those indicated. Do not cut the electric cord

when removing the pump from the application; disconnect

the pump from its regular connections. Failure to follow these

guidelines may void the warranty.

13. If you remove the impeller, be certain to reassemble it cor-

rectly. Impeller spacing is gauged from backplate to impeller

edge. Use the thickness of a dime to space the impeller away

from backplate. Tighten set screws on impeller to 3 - 5 inch

pounds (hand tighten).
