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
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
