[. . . ] Mark and drill four (4) mounting holes using a 9/64" drill and a tube exit hole using a 1-1/2" hole saw. Be sure to use the supplied four (4) plastic spacers to ensure that the PowerPlate is spaced away from the cabinet wall to permit air circulation behind it for best efficiency. Do not mount the PowerPlate flush against the wall as a major loss of performance will result. pOweR plaTe TUBe SeT Drill a 1-1/2" diameter hole through the cabinet wall for the tube set. Position the insulating sleeving OUTSIDE (not inside) the refrigerated space. The end of the sleeve should butt against the outside wall of the box (you will be sealing this joint later with mastic putty included in your kit. ) Route the service port coupling ends of the tube set through the boat to the condensing unit. Before you connect the refrigerant couplings to the power plate, refer back to the section entitled "Refrigerant Couplings" for additional information. Do not allow any dirt, sawdust, foam insulation dust, etc. , to get into couplings ends as this will seriously damage the system. These couplings are different from the couplings that join the tube set to the condensing unit. The small couplings are screwed, o-ringed, and LocTite-sealed to the bases that are in-turn soldered to the copper tubes. Therefore, it is most important that you do not unscrew the small couplings from their bases. Small COUplINg TORQUe ReQUIReD 12­15 foot pounds (less than the large couplings) CONNeCTINg The plaTe COUplINgS (from tube set to PowerPlate) 1. Remove the protective caps of one mating pair of the couplings inside the box (start with either pair). Screw the couplings halves together until they bottom metal-to-metal with very firm pressure (about 4 turns) using two wrenches: 5/8" and 3/4". Using your two wrenches (do not use pliers, visegrips, etc) tighten couplings an additional one flat (1/6 turn). Repeat the above for the other pair of coupling halves. ImpORTaNT: Save all coupling protective caps. If a future service procedure requires that any coupling pair be disconnected, these caps must be re-installed immediately to keep out dirt. To connect the couplings to condensing unit, please refer to section entitled "Refrigerant Couplings. " After completing this section, seal the black rubber insulating sleeve to the outside of the refrigerated box airtight, using Mortite or other (removable-type) caulking sealant. excess tubing: Form a coil about 18" in diameter, (taking care not to deform the tubes) in the horizontal orientation if possible, and secure tightly to the bulkheads, etc. Protect tubing from chafe and vibration with soft sleeving as necessary. 16 ENGLISH Adler/Barbour Series installation Guidelines eleCTRICal CONSIDeRaTIONS WATER COOLED OPTION PACKAGE: How it works and why To get absolutely top performance from your SuperColdMachine, you can add this package at any time in the future if not with your original installation. If inlet air temperature to the SuperColdMachine exceeds 90°F, switching to water cool mode will produce shorter "on" times and lower average amp draw. In tropical conditions, the total daily power consumption can be reduced by 25--40%.
