Vinotemp WM-450SCU, VINO-6500SSL, VINO-4500SSL manual Condensing Unit, Evaporator Unit, Air Sensor

1. Condensing Unit

•Place the condensing units WM150-650SCU in a properly ventilated location. If it is not, heat exhausted by the condensing unit will build up and the cooling system will not operate properly.

•Leave minimum 5 feet clearance for the exhaust side and leave minimum 1 foot clearance for the fresh air intake side.

•Condensing unit shall be elevated to avoid possible flooding and shaded from direct sun. It shall not be exposed to temperatures higher than 110 °F or lower than 45 °F (optional low ambient kit for 20 °F).

2. Evaporator Unit

•The WM15-65SFCL evaporator units shall be installed for ceiling mount with the air supply towards horizontally and air return on the bottom.

•Supply and return air flow from the evaporator unit shall be unobstructed for at least 1 foot.

•There is a gravity drain line so that it can not be installed above the evaporator unit. Otherwise a condensation pump must be used.

3. Air Sensor

•The air sensor can be located in the wine room or the return air area, but not the supply air area.

4. Refrigeration Piping and Charging

NOTES: ALWAYS USE THE SUPERHEAT AND SUBCOOLING, PRESSURE READINGS TO CHARGE REFRIGERANT PROPERLY, THE LISTED CHARGES ARE FOR REFERENCE ONLY.

•The installation order starts from condensing unit (including the receiver), liquid line filter-drier, moisture-liquid indicator (sight glass), liquid line, evaporator unit (including liquid line solenoid valve and thermostatic expansion valve or automatic expansion valve), suction line, and returning to condensing unit.

•The subcooling at the condensing unit shall be around 10°F. The charge may be complete when there are no more bubbles forming in the sight glass.

•The evaporator’s constant pressure expansion valve is set around 38- 40°F at factory. This pressure setting gives a dew point to maintain the humidity for storing wine.

•The superheat at the evaporator unit shall be around 9-18°F under low and high load at 75°F ambient temperature.

•Low side pressure: 33 psig
