Water Out | Mermaid Air Conditioner instruction

pump (SEE FIGURE 5). Remember, all water hose connections must be secured using double stainless steel clamps.

To install the bleed off valve, attach a short length of blue tracer hose to the water-out on the pump and secure the bleed off valve on the other end of the hose. Attach the blue tracer hose that you are running up to the air conditioner unit to the other end of the bleed off valve. Close the bleed off valve. At each connection point, use two stainless steel hose clamps to properly secure the attachment.

WARNING

AFTER INSTALLING "BLEED OFF" VALVE, MAKE SURE VALVE IS IN THE

"OFF POSITION". THAT IS, THE POSITION WHERE WATER CANNOT

FLOW INTO THE BILGE. FAILURE TO CLOSE THIS VALVE WILL RESULT

IN FLOODING WHEN THE BOAT IS PLACED BACK INTO THE WATER POSSIBLY CAUSING SERIOUS WATER DAMAGE OR SINKING OF THE BOAT.

After cutting off the three prong plug, temporarily tape the pump power cord to the end of the water hose and route both items together to the air conditioner compartment (See Following Note). Secure both items along the way at (1) to (2) foot intervals to eliminate sagging or kinking due to boat or wave action. We will connect the cable and hoses to the air conditioner later in the installation.

Note: If you are using a single pump to supply cooling water to two air conditioners, you must install a Pump Relay Box. Before running pump power cable please see Section 3 entitled "Pump Relay Box".

Water Out:

The "water out" thru-hull can be mounted any place on the boat’s hull that is a minimum of (6) inches above the water line. If using a Mermaid supplied thru-hull fitting, the required hole size is 1-1/16 inches so the same hole saw used for the "water in" sea cock can be used. Typically the "water out" thru-hull will be mounted close to the air conditioner to eliminate the extra work of having to route the water hose in difficult places.

The water line on the outside of the hull will give a good base line to determine the lower limit of the hole location. If your boat is new or kept high and dry, you will have to place it in the water to determine the water line. Once you know the water line you can determine where on the inside of the boat you can drill, staying above the water line and out of view. This hole should always be drilled from the inside of the boat. Once you have settled on a location for the hole, check outside again to insure you will be above water level and that you will be clear of any outside ribs or other interference which will not allow the outside lip of the fitting to lay flat against the hull. Always drill a pilot hole and check outside before committing the larger hole.
