[. . . ] AC or DC converters, generators, etc. ) between the control unit, the selector switch, and the battery. Any deviation from this procedure could damage the compressor or the control module and would not be covered under the warranty policy in the back of the manual. When connecting the electronic control module to the battery selector switch, maintain correct wire size as shown in the table below, keep wire runs as short as possible to avoid unnecessary resistance or voltage drop. Do not forget to maintain proper color coding, (red = positive, black = negative) to aid in future electrical troubleshooting. If the wires are incorrectly connected (positive and negative reversed), the unit will not start. Over current protection in addition to fuse provided, must be supplied for the ungrounded conductor at the main switchboard, per ABYC E-9. Use a 15 amp breaker for 12 VDC systems, or a 7. 5 amp breaker for 24 VDC systems. This provides protection from possible short circuits. Because there is a constant milli-amp current applied to the control module even when the thermostat is off, it is recommended to turn the circuit breaker or toggle switch off to protect your battery from discharge when the unit is not in use. When dockside, the Polar Mate can operate against the batteries while using the AC battery charger as a backup (most marine battery chargers will shut off when the battery is fully charged). Use the included wires to connect to terminals #3 and #4 (#4 has two spades bridged together) of the thermostat to the condensing unit terminal strip positions marked "TSTAT. " The thermostat completes a ground circuit for the relay, so polarity does not apply. See the wiring diagram, Figure 7. AC Electrical Wiring Size AC voltage electrical system per ABYC E-8.

Warranty will be paid in accordance with our established schedule of allowances. Dometic Corporation will repair or replace at its option, components found to be defective due to faulty materials or workmanship, when such components, examined by an authorized service dealer or a factory service representative, are found to have a defect for which the company is responsible. In addition, Dometic Corporation will pay labor costs as outlined in its Schedule of Limited Warranty Allowances for removal and reinstallation of such components. [. . . ]
