Mermaid’s 12/24VDC model or our 12/24VDC & 110V with Auto Change-Over m odel, we are sure you will be pleased with their performance. Mermaid provides a one-year warranty on the refrigeration/freezer products and a five- year warranty on their marine air conditioning li n e.
SECTION 3 (CONTROL MODULE) A: Electronic Control Module: The Electronic Control Module is an integral part of the Danfoss BD35/50F compressor system. It transforms direct current power f rom the vessels batteries into alternating current to run the compressor.
C: Compressor Non-Start: If the compressor does not start, the Module will stop the star ting process, & attem pt a re- start every 60 seconds. D: Compressor Speed Too Low: If the compressor speed falls below 1900 RPM the Module will stop the compressor.
NOTE TWO The Electronic Module, although designed for harsh & marine applications, can be damaged from either direct or incidental c ontact with water, & by water f lowing down wires attached to the terminals.
C: Thermostat Sensing Tube: Check to see where you need to a ttach the thermostat sensing tube before mounting the evaporator. The capillary tube (silver capill ary tube) coming off the thermostat is the sensing device. Upon delivery, the sensing t ube will be coiled up near the body of the thermostat.
contact with any electr ical component either inside or outside the ice-box. If the sensing tube needs to be bent within the confines of th e refrigerator or freezer box, it must be done with great care, heeding the warnings above. C: Operation: The thermostat knob is m arked from 1 to 7.
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 rem oved & replaced without leaking refrigerant. Never run the compressor unless all component s of the system are connected together.
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-b low 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).
(3) Run all applicable tests before assuming Module or Compressor to be faulty. B: Compressor Not Running , No Start Attempt. Probable cause Action 1 Supply voltage too low Check vo ltage with a di gital multi-m eter at the terminals on the Module. This must be 11.
connected retaining screw & then ensure tha t the 3- pin plug is seated firmly on the pins of the compressor. 9 Faulty compressor Remove the Module as above, & unplug from the compressor. Check that ohm readings are the same across all terminals of the com pressor.
3 Thermostat type If you are planning to convert your ice box into a freezer, or as a spillover system, a freezer thermostat (0021) must be used. 4 Evaporator type & size If the ev aporator has an even coating of frost, the thermostat is se t on 7, & the system is cycling, the evaporator may be too small.
E: System Runs, Box Temperature Too Low: 1 Thermostat setting Rotate thermostat knob to a lower number. 2 Thermostat type Check that you are using a refrigerator thermostat (0028) for a refrigerator application.
F: Excessive Frost Build-Up: Note: This is the result of moist air be ing allowed to enter the box. Problems are compounded when cold air leaks from the lower area of the box & is replaced by warm, humid air entering elsewhere. 1 Drains & holes not plugged Make sure all drains & holes in the floor & walls of the box are sealed.
