DISASSEMBLY AND USE STEPS
CAUTION: Strainer must always be properly installed before attaching and running pump.
STEP 1
Remove the strainer from the bottom c pump by depressing the lock tabs on sides of the pump.

Determine the desired location for the pump. If only one pump is usually usually located where the water is deepest in the bilge while the boat rest. The installation must allow for complete drainage of the hose. A water pockets must be eliminated by having the hose running level of continuously upward.
STEP 3
Position the strainer so that pump nozzle is in the proper position to connect to the discharge hose.
STEP 4
A. If attaching the strainer to wood, fasten with stainless steel screws attaching the strainer to metal or fiberglass, first mount a wooden blo then fasten the strainer to the wooden block.
STEP 5
Mount the pump on the strainer so that both 11/2" lock-tabs snap in place.(The pump may be reversed on the setabs if so desired.)
STEP 6
Attach 1 1/8"1.D .Hose to the discharge nozzle and fasten with a sta steel clamp. The hose(Model #80)is recommended because it will not when making sharp bends.
If your pump is replacing a competitive model with Smaldia meter how which is hard to replace, you may use the Adaptor Model#69 to ada the smaller hose.
Note:
Restricting the flow from the pump by using a smaller hose does damage the pump. However, it will reduce the flow.
STEP7 Thru-hull Fittings
A. For most installations, install a full size 11/8" 1. D. Thru-hull fitting achieve the rated flow of the pump. Located the thru-hull fitting at le above the water line to prevent water from flowing back into the hull the pump is off.

12" MinimumB. For stern installations, place the11/8" thru-hull fitting high enough in the stern so that submergence of the fitting will not occur under any conditions
STEP 8 wiring
In order to prevent electrolysis and corroded wire connections, it is essential that wire ends and terminals be sealed with heavy-duty mari sealant and located above the highest possible water level by fastenir with insulated staples or plastic straps.
When installing your pump, 16 gauge wire should be used. However, if installation is over 20" from the battery source, the wire size should be increased to 14 gauge. Using a wire that is too small causes undesirable heat in the wires and results in a voltage drop and lower performance of the pump.
STEP 9 fusing
To protect your electrical wiring and automatic switch from possible overload install a fuse in the positive(+)lead from the battery.If using panel switch with a fuse holder, check to see that the proper fuse is used. You may wish to install a panel switch with a built-in fuse hold
STEP 10
Follow one of the two wiring diagrams. Wiring for Manual Operation The manual system is the simplest system but it only provides ON-O control of the pump. Consequently, pump are often left ON longer than necessary.

Fuse On Off Battery Ground Brown Wire Ground PumpWiring for Automatic Operation
The automatic system assures that the vessel is always pumped out, when unattended. In extends the life of the pump and your battery by automatically shutting the pump off when the water has been pumped
The automatic system can also provide for manual control of the pun installing a panel switch. These switches have a “fail-safe” feature w automatically returns the switch to the “off” position ,preventing the pump from being inadvertently left on.

STEP 11
Polarity is important. If it is not correct, the pump rotates backwards. It will still come out of the discharge nozzle but the flow will be very reduced. On the pump the correct polarity will be obtained when the wire of the pump is connected to the POS or+side of the battery. To verify that the direction of rotation(and thus the polarity)is correct is look into the running and see if the impeller rotates in the direction arrow molded into the bottom.Never insert fingers or other objects into inlet hole.
STORAGE
The pump itself is not affected by freezing temperatures. However, the pump is embedded in ice or surrounded by ice, it cannot be. Never turn the pump on if it is embedded in or surrounded by
| Symptom | possible cause | cure |
| Reduced Flow | Plugged strainer | Clean outside of strainer and clean debris from around impeller. |
| Discharge line plugged | Clean out hose by back flushing | |
| Low battery voltage | Check battery condition and charge if necessary. | |
| Kinked discharge hose | If hose is kinked because of sharp bend,convert to hose which will not kink bends. | |
| No water pumped | Wire connections | Make sure wire Connections are not corroded.Visual check is not enough -a s pull on each wire will tell if the wires are still joined. Check to be sure joins are hanging down into the water. |
| Fuse melted | Check fuse to see that it is the correct fuse still blows,check impeller through inlet opening to be sure it is no jammed or stuck with debris. | |
| Float switch failure | Lift end of float switch up-if pump runs, is OK.If pump does not run, turn Manual SWITCH TO on position-if pu runs automatic switch has failed. | |
| Pump won't shut off | Something under float | Clean under the float to make sure debris not holding the float up |
| Stuck float | Check to see that the float is loose and gummy bilge oil. If float action appears sluggish and/or the float does not move intermittent or sporadic operation of the p may occur.This condition is usually the result of oil and/or Dirt accumulating in a around the movable parts of the switch.To correct try soaking the entire switch In Marine cleaner for ten minutes, agitating several times and checking for smooth air free operation of the float. Repeat if necessary | |
| Switch mounted too Low IMPORTANT | If the pump is sucking air and the autorswitch has not reached the OFF position, the switch may be mounted too low for and should be pump reinstalled at least higher than the pump base. | |
| Wires over-heated. Melted insulation | Combination of jammed impeller and wrong size fuse. | 1. Ensure that there is no hair, debris a other debris stuck in the impeller. Please STEP 1 on page 2 for the method of managing debris in the impeller.2. Select the right fuse. |
| Repeated melted fuse | Fuse size or jammed impeller | Be sure fuse has amp rating Check imp to see that it is not bound up by fish I |
