designed and used to provide a subtle temperature between 50~65 °F for
suitable space at a normal environment.
• The refrigerated space will maintain humidity of 50~70% RH even when
the environment becomes dry and humid.
• These temperatures and humilities are optimized for long term storage of
wine.
• Humidity and temperature digital control using patent pending technology
• Optimized air flow for most even temperatures in wine cabinets
• Exchangeable supply grille for front, back and down cold air distribution
• Multiple options for top and rear hot air exhaust
• High efficient tube-axial fans for both condenser and evaporator
• Extra insulation for both thermal and noise isolation
• Unique condensate drain tray for humidity adjustment
• Grill size optimized for easy cleaning and safety
• Stamping ribbed housing for robust structure
• Self-contained ready for use and easy for installation

Installation Instruction
1. Cabinet Location
• Place the wine cabinet in a properly ventilated location. Otherwise, heat
exhausted by the cooling unit will build up and it will not operate properly.
• The exhaust area must not be closed space and must be ventilated. The
ambient temperatures shall not be higher than 90 °F or lower than 50 °F.
1) Rear Exhaust Location
• Leave min 6 “clearance from the rear to the wall.
• Leave min 12” clearance from the top to the ceiling.
• Leave min 6” clearance from the left and right sides.
2) Front Exhaust Location
• Leave min 6” clearance from the front if left and right sides unobstructed.
• Or, leave min 36” clearance from the front if left and right sides obstructed
3) Top Exhaust Location
• Leave min 12” from the top to the ceiling.
• Leave min 2 “clearance from the rear to the wall.
• Leave min 2” clearance from the left and right sides.
4) Side Exhaust Location
• Leave min 6 “clearance from the left or right side to the wall.
• Leave min 12” clearance from the top to the ceiling.

Fig. 2.3 TOP EXHAUST GASKET
(LOCATED ON THE COOLING UNIT)
• Cut a rectangular inside opening at the rear of the cabinet with the 1/4”
clearance inwards to the width and height of the cooling unit. By not going
through, leave 1/2” lip inside at the wall to place the gaskets (see Fig. 2.2).
• If top exhaust, cut another rectangular opening at the top of the cabinet to
the length and width of the top exhaust (see Fig.2.2).
• Make 2 holes at the ceiling to install the 1/4 inside diameter wood thread
inserts (see Fig.2.2).
• Place the gaskets (1) on the gasket lips (see Fig 2.1).
• If top exhaust, place another gaskets along the top exhaust at the top of
the cooling unit (see Fig.2.3).
• Place the cooling unit to a flat and stable place.
• Then move it on the top of the wine rack temporally.
• Move the cooling unit towards the mounting sides and push to press the
gaskets.
• Fasten the 2 brackets and use 7/16” wrench to tighten the 2 screws (see
Fig 2.1).
• If top exhaust, install another top exhaust grille at the top of the cabinet.
• Plug the cooling unit in receptacle.
• Plug the wine cabinet.
NOTE: DO NOT INSTALL ANY DUCTS ONTO THE SUPPLY, INTAKE ANY
EXHAUST.
3. Electrical Cord
• Because of potential safety hazards under a certain condition, we strongly
recommend against the use of an extension cord. However, if you still
elect to use an extension cord, it is absolutely necessary that it will be a
UL LISTED 3-wire grounding type appliance extension cord having a 3-
blade grounding plug and a 3-slot receptacle that will plug into the
appliance. The marked rating of the extension cord shall be 115 V, 15 A.

Temperature Control & Humidity Adjustment
1. Temperature Setting
• Set the temperature at 55 °F for the optimum aging of wine
• On initial start-up, the time required to reach the desired temperature
will vary, depending on the quantity of bottles, temperature setting
and surrounding temperature.
• Allow 24 hours to stabilize the temperature for each new temperature
setting operation
2. Use of the controller
Fig. 3.1 DIGITAL CONTROLLER
1) Display
During normal operating conditions, the display shows the value measured by
the air regulation probe. In case of active alarm, the temperature flashes
alternately to the code alarm.

2) Alarm Signals
2.1 Code Description
2.2 Alarm Recovery
Probe alarms P1”, start a few seconds after the fault in the related probe; they
automatically stop a few seconds after the probe restarts normal operation.
Check connections before replacing the probe. Temperature alarms “HA”, “LA”
automatically stops as soon as the temperature returns to normal value. Alarm
“CA” (with i1F=PAL) recovers only by switching off and on the instrument.
3) Temperature Set-Point
3.1 How to see the set-point
1. Push and immediately release the SET key: the display will show the Set-point
value;
2. Push and immediately release the SET key or wait for 5 seconds to display the
probe value again.

2. The value of the set point will be displayed and the “°C” or “°F” LED starts
blinking;
3. To change the Set value, push the keys
or
arrows within 10s.
