recommend that you secure it with one or two 1/2 inch s/s screws along with duct tape or foil tape.

Now, attach the return air grill and your installation is completed.

B. SYSTEM OPERATION:

Note: If the boat has not been placed back in the water, do so now. The air conditioner requires proper cooling water to operate.

1. Priming The Pump:

a)Because marine air conditioner pumps are not self priming, generally, the pump may need priming each time the boat is removed from the water and then placed back into the water. Priming may also be required when the water strainer is cleaned or when the boat has returned to the dock after being used. Normally, once primed at the dock, the pump will retain its prime until used or taken in and out of the water as mentioned above.

b)To prime the pump, open the sea cock and view the water flow through the clear red stripe hose. If the water flows into the input of the pump with no air bubbles in the strainer or hose, the pump is primed. However, if air bubbles are present you must loosen the hose clamps on the pump discharge hose (blue stripe or black reinforced) and momentarily remove the hose. Water will immediately flow from the pump breaking the air lock. Quickly replace the hose and retighten the hose clamps. The pump is now primed. If you have installed the optional "Bleed Off" valve, it is usually not necessary to remove the discharge hose from the pump. Open the "Bleed Off" valve until water flow is observed and then close the valve. (Ideally this water should be directed to the bilge or a container that can be later discharged overboard).

WARNING

AS STATED EARLIER, FAILURE TO CLOSE THE "BLEED OFF" VALVE WILL RESULT IN FLOODING AND POSSIBLE SINKING OF THE BOAT.

Note: If water does not flow from the pump when the discharge hose is removed or from the "Bleed Off" valve when opened, the pump is not below the water line of the boat and must be remounted.

2. Power:

a)With the air conditioner circuit breaker in the "OFF" position connect the dock power cord back to the boat.
