NOTE
See the voltage, frequency and current specified on the label of the
cooling unit.
The rated cooling capacity is determined under the cabinet and
ambient temperatures of 55°F and 75°F with R13 interior and R19
exterior insulations. Higher ambient temperatures and less insulation
will cause reducing the capacity.

Installation Instructions
NOTE
Mounting brackets, screws, gaskets and other seal materials are not
included.
Do not install any ducts onto the supply, return, intake and exhaust.
CAUTION
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 extension cord having a 3-
blade grounding plug and a 3-slot receptacle that will plug into the unit.
The marked rating of the extension cord shall be 115 V, 15 A.
1. Cabinet Location
• Place the wine cabinet in a properly ventilated location. Otherwise, heat exhausted
by the cooling unit will build up and it may cause the cooling unit not to work
properly.
• The exhaust area must not be closed space and must be ventilated.
• The ambient temperatures shall not be higher than 78°F for running WM-1500LOWP
& 1500LOWP-TE or 95°F for running WM-2500LOWP & 2500LOWP-TE and shall not
be lower than 50 °F for all units.
1) Rear Exhaust Cabinet
• Leave min 6 “clearance from the rear to the wall.
• Leave min 12” clearance from the top to the ceiling.
• Leave min 6” clearance on the sides.
2) Front Exhaust Cabinet
• Leave min 6” clearance on the front if the sides are unobstructed.
• Or, leave min 36” clearance on the front if the sides are obstructed
3) Top Exhaust Cabinet
• Leave min 12” from the top to the ceiling.
• Leave min 2 “clearance from the rear to the wall.
• Leave min 2” clearance on the sides.
4) Side Exhaust Cabinet
• Leave min 6 “clearance on the side that hot air exhausts.
• Leave min 12” clearance from the top to the ceiling.

- 6 -
2. Cooling Unit Installation
• The cooling unit produces cooling supplied into the cabinet, meanwhile it also
generates heat that must be exhausted outside the cabinet. So the cold-air supply
and warm-air return must be separated from the hot-air exhaust and ambient-air
intake. Foam tape gasket may be used to seal them. The cooling unit must intake
adequate fresh ambient-air to work properly. The ambient-air intake and hot-air
exhaust must not be short-circulated.
1) Making Cutout
• Make a rectangular through hole at the rear wall of the cabinet with 1/4” less than
the width and height of the cooling unit. Make 1/2” tabs to place the gaskets as
shown in Fig. 2.1.
• If it is a top exhaust installation, make another rectangular hole at the top of the
cabinet with the length and width of the top exhaust as shown in Fig. 2.2.
• Install 2 pieces of 1/4” ID wood thread inserts on the ceiling as shown in Fig. 2.3.
• Install the rear gaskets (1/2” foam tape) as shown in Fig. 2.4.
• If it is a top exhaust installation, install the top gaskets on the cooling unit as shown
in Fig. 2.5.
2) Installing Cooling Unit
• Push the cooling unit towards the mounting tabs until it stops and press the gaskets
as shown in Fig. 2.6.
• Use two mounting brackets and two 1/4” screws with 7/16” wrench to secure the
cooling unit as shown in Fig. 2.6.
3) Low Profile Front Grille
• Install an exhaust cover to redirect the hot air to the front as shown in Fig. 2.9.
• Install the low profile front grilles as shown in Fig. 2.9.

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.
2. 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
3. How to see temperature set-point
1) Press and immediately release the SET key, the display will show the set-point value.
2) Press again and immediately release the SET key to display the probe value.
4. How to change the set-point
1) Press and hold the SET key until the “°C” or “°F” LED starts flashing and the set-point
is displayed.
2) Press the up/down keys / to change the set-point value within 10 sec.
3) Press the SET key again to store the new set-point value.
NOTE: The unit turns on at set-point Set plus regulation differential Hy after anti-short
cycle AC has elapsed; the unit turns off at set-point Set.
5. Manual Defrost

7. How to calibrate the air probe
If the actual cellar temperature differs from the setting temperature, set parameter ot =
actual cellar temperature minus set-point.
8. How to adjust defrost cycle
In case there is excessive frost, the parameters FnC = C-y, idF = 4 and MdF = 20 can be
used to avoid frost.
9. How to adjust the humidity
The parameter Fon is used to adjust the humidity in the wine cellar. Higher Fon results
in higher relative humidity. Use a separate hygrometer to monitor the humidity.
10. How to set alarm call
1) Speech notice will be sent to your phones when the cellar temperature is ALU higher
or ALL lower than the set-point Set.
2) In order to test the call function, set parameters Ald = 0 and dAO = 0. After testing,
set Ald = 60 and dAO = 23.
11. How to set low cellar temperature heater
The heater turns on at SAA minus Shy; the heater turns off at SAA.
NOTES:
• Use a forced air heater to warm up the wine cellar.
• If there is a thermostat on the heater, bypass it or set the thermostat at the highest
level.
• If the heater runs more than 10 A current, use a 120VAC coil contactor

Care Guide
1. Cleaning Condenser
• Clean the condenser regularly at least every 6 months.
• Condenser is located on the ambient air intake side of the cooling unit.
• Use a condenser brush or a vacuum cleaner with an extended attachment to clean
the condenser.
2. Removing Condensate
Remove the excessive condensate if it is accumulated on the cooling unit in high
humidity conditions.
3. Removing Unit
When you remove the cooling unit, beware water may come out of the unit.

Troubleshooting
This Troubleshooting Chart is not prepared to replace the training required for a
professional refrigeration service person, not is it comprehensive
Complaint
Possible Causes
Response
1. Unit not running
a. Power cord not plugged
b. No power from supply
c. Incorrect or loose wirings
d. Low voltage
e. Setting higher than ambient
temperature
f. Cut-in too high
g. Defrost light blinking
h. Compressor light blinking
i. Defective controller
a. Check power cord
b. Check receptacle and fuses
c. Check all wirings and connections
d. Contact an authorized electrician
e. Lower temperature setting
f. Reduce Hy
g. Unit is under defrost mode
h. Unit is under anti-short cycle delay
i. Call service for diagnosis
2. Unit not starting,
but temperature
rising high
a. Anti-short cycle
a. Reset AC
3. Temperature
fluctuating
a. Air probe
a. When using an air probe, the wine
bottle temperature is mainly controlled
by the average air temperature. If the
set-point is 55°F with the differential
4F, the cooling unit turns on at 59°F of
air temperature (It may be higher than
59°F if it is in anti-short cycle or defrost
cycle) and turns off at 55°F of air
temperature. The average air
temperature is 57°F, and then the wine
temperature is around 57+/-0.5°F. The
air is light enough to change so quickly
that it maintains relatively constant
average temperature that would
prevent wine bottle temperature from
fluctuating.
4. Temperature
high, unit
stopping and
starting

a. Temperature setting high
a. Lower the setting
5. Temperature
