Mermaid Air Conditioner manual Pump

Never screw the pump directly to the hull. If a stringer or other structure is not handy, you may have to fiberglass a mounting board to the hull to accept the mounting screws.

Note: If you are supplying cooling water to more than one air conditioner a larger GPH pump is required. Follow the mounting instructions furnished with the larger pump. Also a “tee fitting” must be used on the discharge side of the pump to run cooling water to each unit.

Using the appropriate length of the 3 feet of 3/4 inch red stripe marine hose and (2) s/s hose clamps per connection, connect the sea cock, water strainer and pump together.

The Pump:

IMPORTANT

ON DUAL AIR CONDITIONER INSTALLATIONS, AN IN-LINE SHUT OFF VALVE MUST BE INSTALLED IN EACH OF THE “WATER IN” LINES TO ALLOW OPERATION OF EITHER AIR CONDITIONER IF ONE UNIT IS REMOVED FOR SERVICE.

WARNING

ALL HOSE CONNECTIONS MUST BE SECURED USING TWO (2)

STAINLESS STEEL HOSE CLAMPS. FAILURE TO DOUBLE CLAMP ALL HOSE CONNECTIONS MAY RESULT IN A HOSE DISCONNECTING WHICH COULD CAUSE FLOODING DAMAGE AND /OR SINKING OF THE BOAT. DAMAGE TO THE AIR CONDITIONER FROM EXCESSIVE AND RECURRENT LEAKING DUE TO FAILURE TO DOUBLE CLAMP ALL CONNECTIONS WILL VOID THE WARRANTY.

The 5/8 inch blue stripe water hose (or black reinforced hose – deluxe kits) and the pump power cord may now be routed to the air conditioner compartment. If the power cord that is permanently attached to the pump is not long enough to be routed to the air conditioner compartment it must be extended using 16 gauge boat power cable. Cut off the connector on the end of the pump power cord (if present) and splice in the 16 gauge boat power cord. Appropriate electrical splicing must be used and the connection must be water proof and secured well above the bilge water level to insure that the connection will always remain dry. We have provided a piece of heat shrink tubing to ensure proper insulation after connectors are applied.

WARNING

FAILURE TO KEEP THIS ELECTRICAL CONNECTION DRY COULD CAUSE

FIRE AND DESTRUCTION OF THE BOAT.

Note: Loss of prime on the water pump is a common occurrance. An optional "Bleed Off " valve is available that aids in regaining pump prime. If you are using this option, it must be installed at this stage of the installation at the output of the
