CONTROL SETTINGS 92074 High Pressure Cut-Out: 350 PSI Low Pressure Cut-Out: 44 PSI Freeze Thermostat: 35_F (Probe on evaporator outlet) Hot Gas By-Pass This option feeds hot gas to the evaporator when the water reaches set-point. The hot gas forces the water temperature to increase 1_F quicker, which turns the cooling back on.
INSTALLATION LOCATION: – – – Indoors. Adequately ventilated area. (2 ft. of space on air intake and discharge sides). Ambient temperature range (40_F – 100_F). (Optimum 80_F) ELECTRICAL: All wiring must conform to the National Electric Code and any applicable local codes.
MAINTENANCE CAUTION: Disconnect electrical power before performing any maintenance. 1. Keep condenser fins clean by blowing compressed air through the fins from the fan side as required to eliminate any dirt or debris. 2. Drain and flush circulation system periodically to reduce the chance of restriction due to contaminants in the water. 3. Clean strainer monthly.
