B: Wire Size:

Consult ABYC tables for 3% volt drop. Never use less than 10 gauge wire.

C: Overload Protection:

Use either a breaker or fast-blow fuse with 15 amp rating for a 12/24v supply, and/or a 8 amp fuse for the 110v a/c side. (These items are provided on new installations from the Mermaid factory).

D: Connections, Power:

If wiring from the factory needs to be removed, connect the power supply to the Module to the top two terminals, observing the correct polarity. Reversing the polarity at the terminals will prevent the compressor from running but will not harm the system. 12/24VDC & 110V Auto Change-Over units have clearly marked 110v (+) and (N) – DO NOT incorrectly put the 12/24VDC lines to here. It will not cause permanent damage however, the unit will not operate. Follow the wiring schematic carefully. SEE LAST

PAGE OF MANUAL FOR WIRING SCHEMATIC

E: Connections, Thermostat:

Connect the two slip-on connectors from the thermostat to the corresponding terminals on the Electronic Module, color & polarity are important. One connector must go on the “C” terminal, & the other to the “T” terminal. Again, follow the enclosed wiring schematic.

A: Note:

(1)The voltage must be checked at the terminals on the Module, with the supply wires attached.

(2)Start-up may occur up to one minute after power is supplied & thermostat is on.
