together, they allow the refrigerant to flow through the system without leaking out to the atmosphere. If needed, they can be undone to enable a faulty component to be removed & replaced without leaking refrigerant.
Never run the compressor unless all components of the system are connected together.
B: Connecting the Quick Connect Fittings:
Leave the clear plastic dust plugs installed until you are ready to connect the system together. After you have removed the plugs, keep them in a safe place in case you need to remove or replace a component later. Push the male & female fittings together & then carefully rotate the collar on the female fitting until it starts on the thread on the male end, making sure that the fitting is not cross-threaded & the male end does not rotate. Continue making up the collar of the female end, either by hand or with a crescent wrench, while preventing the male end from rotating by restraining it with another wrench. It is most important not to let the male end rotate at all during this whole process. Tighten the collar until it nearly covers the threads on the male fitting. It is not necessary to use excessive force as the seal that stops the refrigerant from escaping is made with an o-ring & does not depend on the fitting being wrenched down hard. If there is a continuous hiss after the connection has been completed, disconnect the fitting & check that the o-ring has not been damaged.
SECTION 8
(ELECTRICAL)
A: Power Supply:
The power supply to the Electronic Control Module must given particular attention to prevent nuisance problems & compressor non-operation, shutdown, or failure. All incoming power electrical connections should be either soldered or made with good quality crimpers & crimp connectors of the correct size & type. All switches, breakers & connections must be in good condition & be designed & constructed for marine use. It is suggested that during the initial start-up the supply voltage be monitored at the terminals on the Module before, during, & after the compressor starts, to ensure that the voltage stays steady & does not fall appreciably. This test should be conducted with as many other DC loads turned on as is practical. Each model Mermaid produces is pre-wired and tested for voltage drop. It is not necessary to change any wiring connections made at the factory unless damaged during installation. This section is to ensure your incoming power (12VDC, and/or 110V) is wired properly to the pre-stripped connections from the Mermaid factory.
