Mermaid Air Conditioner manual Electrical Power

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 hose to the thru-hull fitting. Route this hose into the air conditioner compartment where it will eventually be connected to the condensing coil "water out" fitting.

3. Electrical Power:

Both the air conditioner and pump require 115 vac, 60 hertz power to operate. (220v models are available) This power is obtained from the master 115 vac Circuit Breaker Panel in the boat. Power is routed from this panel to the air conditioner. The air conditioner will then supply power to the pump as required.

WARNING

BEFORE PROCEEDING FURTHER, CHECK TO INSURE THAT ALL 120 VAC

POWER HAS BEEN DISCONNECTED FROM THE BOAT AND CIRCUIT BREAKER PANEL. FAILURE TO DO SO COULD CAUSE ELECTRICAL SHOCK RESULTING IN SERIOUS INJURY OR DEATH

Using 12 gauge boat power cable, beginning on the inside of the Main Circuit Breaker Panel, route the cable to the air conditioning compartment. Leave ample excess before cutting to allow for positioning of the unit’s electric box at time of final hook up.

Connection of this cable to the air conditioner electrical box will be covered later.

At the circuit breaker panel locate a blank hole and install a 20 amp circuit breaker of the same style as those breakers currently in the panel. Note that all of the breakers are connected together on one side by either a buss bar or individual jumper wires. Connect the new breaker in the same manner. Remove about 12 inches of the outer insulation from the end of the boat cable to expose the inner wires. This cable contains (3) inner insulated wires which are "BLACK", "WHITE" and "GREEN' in color. Using the appropriate wire connectors, as those currently used in the panel, connect the wires as follows: "BLACK" to the remaining terminal on the circuit breaker, "WHITE" to the buss bar connecting all "WHITE" wires together and the "GREEN" to the buss bar connecting all "GREEN" wires together. Included in the installation kit, if you purchased that option, is a small Mermaid A/C sticker. Place this on your breaker panel to properly denote the air conditioner circuit breaker. The Main Circuit Breaker Panel can now be closed up.

FOR 220V UNITS THAT HAVE A 4 WIRE SYSTEM WITH RED, BLACK, WHITE, AND GREEN WIRES, THE FOLLOWING APPLIES:

BLACK GOES TO BLACK (HOT)

RED GOES TO WHITE (NEUTRAL)

GREEN GOES TO GROUND

WHITE GETS CUT OFF AND NOT USED
