Pressures are approximate: High pressure will momentarily rise beyond operating
pressure until the expansion valve starts to restrict flow. Condensing pressure will be
15 degrees above water temp.
Low pressure will drop from equalized at start up to settle at the indicated low reading in
a period of about 45 minutes depending on the number of plates and starting
temperature. Proper thermostat set up should cycle the compressor in this low-
pressure range.
THE EXPANSION VALVES HAVE BEEN FACTORY ADJUSTED FOR OPTIMUM
PERFORMANCE. DO NOT ADJUST THIS VALVE FOR ANY REASON.
INCORRECT SETTINGS MAY RUIN THE COMPRESSOR!
