INSTALLATION

Little Giant pumps are carefully packaged, inspected and tested to insure safe operation. When you receive your pump,

examine it carefully to be certain that there are no broken or damaged parts, which may have occurred in shipment. If damage

has occurred, (See Replacement Parts Section), make notation and notify the firm from which you purchased the unit. They

will assist you in replacement or repair.

1. Be certain electrical outlet to be used meets the requirements of the National Electrical code, as well as local electrical

codes, including grounding, and GFCI protection. Also verify that outlet is properly sized and located for this pump. Your

installation may require a certified electrician, or plumber. See Electrical Connections Section.

2. If necessary, check your local plumbing codes to verify that final installation will be in compliance with their requirements.

3. On APCP models, secure the two power cords together using the four cable ties (Item 21), provided. Spiral these around

the two cords at intervals of approximately five feet. Connect a garden hose to the hose adaptor, or use a 1 inch nipple

and flexible PVC tubing secured to the pump discharge. Note: If flexible 1 inch PVC tubing is used, the free end must be

secured so that it cannot blow back onto the pool cover in high wind.

4. Remove pump screen (Item 22) and base plate (Item 8) from the carton. The screen and the base plate are shipped

unassembled. Prior to operating the pump, the screen and the base plate must be installed as shown in the replacement

parts diagram. Attach the screen and the base plate using the 1/4–20 nylon screws (Item 9) and torque screws 8—10

in-lbs.. NOTE: If the plate is not installed, pump may tip, which can result in switch malfunction and possible damage to

the pump if switch causes pump to run without water being present. See SAFETY INSTRUCTIONS section. The plate is

an integral part of the safety design of the pump, and failure to attach properly voids this important safety feature.

5. Gently lower pump with stabilizing plate onto the pool cover by holding onto the garden hose. Be certain that you do not

pull power cord plug onto pool cover. It is recommended that two people position the pump. One person should hold

onto electrical cord plugs while second person positions pump at desired location on pool cover. The pump is equipped

with an 18 AWG power supply cord that is 25 feet long, and has a 3-prong grounding type plug. Once in position, and

proper electrical connections have been made, the pump is ready for testing. See ELECTRICAL.

PUMP SPECIFICATIONS

CAPACITY SIZING INFORMATION

The 1200 GPH performance was obtained through a 1 inch I.D. tube, with friction losses neglected. Using a 5/8" garden hose

60 foot long reduces this performance to approximately 300 gallons per hour due to friction losses in the garden hose. If your

area frequently has heavy rainfalls, (1-2 inches per hour), it may be necessary to use 1 inch tubing. This should be available in

most pool supply stores. The number of gallons of water that your pool will collect in a rainfall of one inch per hour can be

computed as follows:

Cover overall length (FT) x cover overall Width (FT) x .6234=Gallons Per Hour

(Note: This is cover dimension, and not pool dimension.)

Example: A pool cover which is 16' by 32' would collect:

16 x 32 .6234=319 Gallons in 1 hour, in 1 inch per hour rain.

A pool cover which is 20' by 40' would collect:

20 x 40 x .6234=499 Gallons in 1 hour, in 1 inch per hour rain.

NOTE: Become familiar with the Safety Instructions. During the rainy season, you should check daily to see that your pump is

functioning properly. Also, if you experience high winds, or excessive movement of the pool cover, be certain that the power

supply cord has not been pulled onto the cover, and that the pump is still upright, with the discharge hose properly

positioned. If you plan to be away from your pool for extended periods of time, it is recommended that a friend or neighbor

periodically check your pool cover pump, and verify that everything is still functioning properly. Be sure to review the SAFETY

INSTRUCTIONS and ELECTRICAL SHOCK HAZARDS with them!

OPERATION

AUTOMATIC OPERATION (APCP Models Only): The water level switch, rated 10 Amps, is activated by pressure against a

diaphragm. This is caused by water rising around the switch housing with the pump resting upright on the stabilizing plate.

This switch relies upon air to flow through a "breather tube" (See Figure 1). The switch should cause pump plugged into piggy

back plug, (See Figure 1), to come on when the water level is approximately 2-3 inches deep. Pump should remain running

until the water level is approximately .50-1.50 inches deep. Note: Temperatures near freezing may cause the "ON" level to go

as high as 4 inches, and the "OFF" to be as high as 2 inches.

MANUAL OPERATION or OTHER USES: Pump can be operated manually by plugging its power cord directly into

outlet. See SAFETY INSTRUCTIONS, paragraph #3. If pump is used for something other than pool cover water removal,

the stabilizing plate can be removed by removing the four screws which attach it to the pump base. Remove the screen

and then replace the screws to secure the screen to the pump base. Make sure you keep stabilizing plate. This is an

important item which helps prevent pump from tipping and causing malfunctions to switch, and must be in place when

pump is used on pool cover. See SAFETY INSTRUCTIONS and ELECTRICAL SHOCK HAZARD before converting pump

for other applications.

Read these instructions carefully. Failure to follow could cause serious bodily injury and/or property damage. Your

pump is an electrical product and caution should be used when handling the pool cover pump or its electrical cord.

Small children or pets may require restraining devices to prevent them from entering wet areas surrounding the pump or

its power supply connections.

1. This product is provided with a three prong grounding plug, to reduce the risk of electrical shock. When pump is in

operation, make sure it is properly connected to grounded outlet. For additional safety, a GFCI device is

recommended either at the outlet supplying power to the pump or at Circuit Breaker Panel Box. An in line GFCI is

included on GFCI Models.

2. Never pump chemicals or corrosive liquids with this pump. This could damage the integrity of the enclosure an cause an

electrical short.

3. Do not run this pump dry. If switch does fail or pump is used manually, always be certain that water is available. Running

this pump without water may damage the integity of the enclosure and cause electrical short.

THIS PUMP IS INTENDED TO REMOVE WATER FROM YOUR POOL COVER TO HELP

PREVENT DAMAGE, BUT IS NOT INTENDED TO BE A LIFE-SAVING DEVICE TO

PREVENT DROWNING IN COVER WATER. ACCUMULATED WATER DOES

PRESENT A POTENTIAL DROWNING HAZARD AND POOL OWNER MUST TAKE

ACTIONS TO PREVENT THIS SHOULD THE PUMP FAIL TO OPERATE.

SAFETY

INSTRUCTIONS

WARNING ELECTRICAL SHOCK HAZARD

4. If service is required, proceed carefully. The pump and surrounding areas may be covered with water. Never plug or

unplug the device while standing in wet or damp surfaces. If necessary, remove power at the Breaker Panel or have

certified electrician remove power before attempting to service. Serious or fatal shocks could result if proper procedures

are not followed.

A. Disconnect the power at the main electrical service box, by switching the appropriate circuit breaker or removing

fuse. In applications where screw type fuses are used, remove only with one hand while other hand or torso are free

from contact with anything. Do not stand in water and do not touch any other conductive surfaces.

B. Remove pump cord plug only after the power to the supply outlet has been removed. See Service Instructions

before proceeding.

5. Remove pump when freezing conditions will cause water to freeze. Freezing water may result in rupture to pump and/or

switch enclosure and could result in possible electrical short.

6. Never pump gasoline or other low flash point fluids with this pump. Explosion or fire could result.

ELECTRICAL

1. Your pump is supplied with a 3-prong electrical plug. The diaphragm switch on APCP models is supplied with a 3-prong

piggyback plug/receptacle on the cord. The third prong is to ground the pump to prevent possible electrical shock

hazard. Do not remove the third prong from the plugs. For automatic operation, plug pump plug into piggyback

receptacle, then plug piggyback plug into properly grounded outlet. For manual operation, plug pump plug directly into

properly grounded outlet. These connections are illustrated in Fig. 1.

2. A separate branch electrical circuit is recommended. The electrical power required is 5 amps at 115 VAC.

3. Be sure that electrical connection cannot be reached by rising water. Under no circumstances should the connection be

located where it may become flooded or submerged by water.

4. Switch cord contains a small white breather tube which extends out of switch plug (see Fig. 1). Be sure switch cord is not

pinched and non-restrictive air flow can occur in breather tube. Do not allow water to enter into breather tube.

Non-restricted air flow is required for proper switch operation.

5. On GFCI models, test GFCI device per the instructions on the back of the device. Test the pump after all electrical

connections have been made. Run water into area where pump is to be placed. Do not attempt to run the pump without

water; this could cause damage to the pump. Fill the area to a normal "On" level and allow the pump to remove water to a

normal "Off" level.

Always disconnect the electrical power before touching the pump, discharge or electrical plug when water is present in

the area. Failure to do so can result in serious bodily injury and/or property damage. Always connect pump to grounded

receptacle. See Safety Instructions.

SERVICE INSTRUCTIONS

1. CAUTION: Before servicing the pump, disconnect the pump from electrical service, unplug cord, remove fuse or turn off

disconnect box.

2. The motor housing of the pump is completely sealed and requires no service. Disassembly of the motor housing or

alteration of the power cord voids all warranty.

3. The motor is a continuous duty type sealed in oil with an automatic thermal overload protecter device.

4. The pump can run against a restricted discharge such as a fountain without damage to the pump.

5. Keep pump clean and in a well maintained condition at all times. Pump should be thoroughly cleaned for summer

storage. If the pump becomes clogged, remove the four screws which secure the plate to the pump and clean out

the debris.

6. If necessary remove the six (6) screws holding the volute base to the motor housing and clean the volute. These screws

are located under the plastic stabilizer plate on the base of the pump. (See item7 on the replacement parts page). If the

impeller is removed make sure that a spacing of .050" with shaft pushed toward housing is maintained when

reassembling. (See Fig. 2.).

7. When reassembling be certain seal surfaces are clean and install the seal ring between the volute base and the motor

housing. Note that the stabilizer plate is a safety feature for pool cover applications to prevent pump from falling over and

causing switch malfunctions. Make certain that the plate is in good condition and is properly secured to the pump base.

Tighten plate mounting screws to 8 in. - lb. torque.

8. This pump does not require lubrication inside the motor enclosure. The motor housing is filled at the factory with a

dielectric oil for motor heat transfer, and lifetime lubrication of the bearings. Use of any other oil could cause

damage and will void the warranty. If oil escapes from the enclosure, disconnect power to the pump and remove

pump from application.
