Vinotemp VINO2500SSD Refrigerator User Manual


 
- 1 -
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
