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.
When installing the thru-hull fitting apply an ample amount of marine sealant to the
outside lip of the fitting and its mounting post. If possible, have someone hold the
outside of the fitting to keep it from turning when you attach the retaining nut from the
inside. Be careful not to over tighten the nut. Use two (2) s/s hose clamps to attach the
