Installation Instructions
WARNING
•Always check wiring harness connections before initiating any test procedures.
•Disconnect electric power from the appliance before performing any maintenance or
repairs.
•Voltage checks should be made by inserting meter proves beside the wires in the
connector blocks with the electric power source on and the connector block plugged
in.
•Resistance checks should be made on components with the electric power off and the
connector block disconnected.
NOTES:
oMounting brackets, screws, gaskets and other seal materials are not included.
oDo not install any ducts onto the cold-air supply and cellar-air return.
oDucts can be used on the hot-air exhaust and ambient-air intake side
oMounting brackets, screws, gaskets and other seal materials are not included.
1. General Instructions
• The cooling unit produces cooling supplied into the cellar, meanwhile it also
generates heat that must be exhausted outside the cellar. So the cold- air
supply with cellar-air return side and the hot-air exhaust with ambient-air intake
side must be separated and sealed. Through-wall installations can separate
these two sides.
• Furthermore, the condenser of cooling unit must intake adequate fresh
ambient-air to work properly. The ambient-air intake and hot-air exhaust must
not be short-circulated. Both of them must remain unobstructed 36” clearance
all around. The area into which the hot air is exhausted must be well ventilated.
If it is not, heat generated by the unit will build up and the unit will not operate
properly.
• Additionally, cold-air supply from the front grille must remain unobstructed 36”
clearance.
• The ambient temperatures shall not be above and below what are specified.

2. WM-6500~8500HZD-DE through-wall installation
Fig. 2.1 THROUGH- WALL INSTALLATION
• The cooling unit shall be mounted near the ceiling with equal distance from each side
of the cellar.
• Cut a rectangular opening at the wine cellar wall as illustrated. The dimensions of
the opening shall be 1/4” larger than the width and height of thecooling unit.
• Construct a shelf as shown. The shelf must be capable of supporting the weight of
the cooling unit and preventing it from moving.
• Place the cooling unit on the shelf with the back of the unit flush with the outside of
the wall.
• Seal the clearance between the cooling unit and opening with a high quality weather
stripping, polyurethane spray foam, or foam tape. Cover the seal withmolding and
attach the molding to the wall not the unit.
• Attach the adapter of hot-air exhaust duct hood to the rear of the cooling unit with
screws; then attach the hot-air exhaust duct hood with adhesive tapes.
• Attach the ambient-air duct hood to the rear of the cooling unit with adhesive tapes.
• Attach the insulated ducts to the hoods with adhesive tapes.
• Secure the ducts with conduits to the cellar exterior walls and make sure they are not
curled, twisted, bent and clogged.
• Plug the unit into a properly grounded and dedicated outlet of adequate capacity.

-7-
NOTE:
• The cooling unit can be installed with the front of the unit flush with the
inside of the wall. Construct a shelf outside the cellar accordingly.
• The exhaust and intake ducts can be 50 ft in total.

4. Cellar Construction
This is only a guide and shall be considered as minimum requirements.
All interior walls and floors shall have a vapor barrier and a minimum of R13
insulation. All exterior walls and ceiling shall have a vapor barrier and a minimum
of R19 insulation. The vapor barrier shall be installed on the warm side of the
insulation. All joints, door frames, electrical outlets or switches and any pipes or
vents that go through the cellar shall be sealed to prevent air and moisture leakage
into the cellar. Concrete, rock, and brick are not insulation or vapor barriers.

-10-
Doors shall be of a minimum size, insulated to at least R13 and tightly sealed
with high quality weather stripping. Be sure to seal the bottom of the door and fill
gap between the door’s frame and wall before installing the cap molding.
In order to maintain 55 °F in the wine cellar, the ambient temperature surrounding
the enclosure shall not exceed the temperature of the cellar by morethan 25 °F.
No cellar wall shall receive direct sun or strong wind.
Lighting shall be of low wattage, with a timer to insure lights are not left on when
the cellar is not occupied.
The cooling system will not be able to maintain the proper temperature if fresh
moisture-laden air is constantly being introduced to the cellar. Symptoms of this
condition are; cooling unit runs all the time with only a slight reduction in
temperature and/or water overflows from the unit. Because of the temperature
difference between the inside and outside, very small cracks can allow large
amounts of outside air to enter into the cellar. Please be aware that moisture can
pass through solid concrete, paint and wood. Often a newly constructed cellar
contains fresh wood, paint, concrete and other building materials. These materials
contain large amounts of moisture. When placed into operation in this type of
environment, the system will work harder to remove this extra moisture resulting
in increased “run” time.

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

-14-
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:
ï Use a forced air heater to warm up the wine cellar.
ï 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.
4. Installing Drain Line
The units are equipped with an additional drain fitting. In case of extreme humidity
there is a drain line needed, remove the drain plug on the bottom left at the rear,
then remove the connection plug and fit a 0.375” OD drain tube into the drain
connection. Install the cooling unit with the front higher than the rear.

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°Fof 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.
