NOTE TWO
The Electronic Module, although designed for harsh & marine applications, can be damaged from either direct or incidental contact with water, & by water flowing down wires attached to the terminals. When attaching wires to the terminals on the Module, make sure that all wires approach from below the terminal, & endeavor to mount the Compressor & Module combination in a location that is clear of existing & potential water leaks.
SECTION 5
(EVAPORATORS)
A: Location:
All types of evaporator need to be located as high as possible in the ice-box/refrigerator to maintain the correct temperatures. The series of flat evaporators may be carefully bent on a 2” radius to follow the shape of the ice box. A section of PVC piping with an outside diameter of 2" may be used for this purpose. This must be done slowly & with great care to avoid excessive kinking of the channels in the evaporator. The channels will look like tubing inside the evaporator. The evaporators must also be mounted on the walls of the compartment with the indicator arrows pointing upwards (if present). Mounting the evaporator on the bottom of the compartment will result in damage and inadequate cooling of the compartment.
B: Installation:
All evaporators have approx. 6' of copper tubing attached, with dust-plugs in the end fittings that must remain installed until the connections are ready to be made. A 1 1/2" hole needs be drilled in the wall of the ice-box, as high as possible, & through successive bulkheads as required. Carefully unroll the tubing & feed it through the holes to the area where the compressor/condenser is located. Some evaporators have sections of aluminum tubing close to the body of the evaporator that must be handled very carefully & not bent. Warnings to that effect are attached to the evaporators in question.
Any bends that need to be fashioned in the tubing must be made carefully & of as large a radius as possible to avoid kinking . The section of insulation that is free to slide on the tubing should be positioned so that it covers the tubing starting at the point where it exits the ice-box. Once the evaporator is installed, this exit hole must be sealed with expanding foam, refrigeration putty, or other suitable material. Any excess tubing may be carefully rolled up & fastened out of the way in a horizontal orientation.
