Vinotemp VINO8500SSD, VINO6500SSD, VINO4500SSD manual Air Sensor, Refrigeration Piping and Charging

•The WM25-85SFCD evaporator units shall be installed for ceiling mount with air supply on both sides 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.

•If equipped with a TXV, the evaporator superheat is set around 8-10 °F for a 10 °F TD system at factory.

•If equipped with an AXV, the valve is set around 38-40°F at factory and 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

•High side pressure: 130 psig at 75 °F ambient temperature and 150 psig at 90 °F ambient temperature
