PRE-INSTALLATION CONSIDERATIONS
Air Flow
The model 315W uses a fan to take room air in through
the front left side of the kickplate/grille (See Figure 2-1).
Figure 2-1. Air Flow
Figure 2-2. Power Cord and Wall Outlet
Note: Follow all local, state and national codes.
Possible Need for Unit Removal
In most cases it will be necessary to pull the 315W unit
from its installation for service. For this reason, the
area under the 315W should be at the same height as
the surrounding finished floor and any decorative molding must be removable.
Moving the Unit
When the unit is moved into the house, or needs to be
removed from the house for service purposes, it is recommended to use a hand truck or dolly. Be sure to
position dolly on the side of unit and securely tape the
door shut so it will not open while transporting the unit.
• PLUG UNIT INTO GROUNDED 3-PRONG OUTLET.
• DO NOT REMOVE GROUND PRONG FROM
POWER CORD.
• DO NOT USE A 2-PRONG ADAPTER.
• DO NOT USE AN EXTENSION CORD.
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN
RESULT IN FIRE, ELECTRICAL SHOCK, OR DEATH!
Airflow through the kickplate/grille must never be
obstructed. Doing so will cause a decrease in performance and possible damage to the 315W unit.
The minimum ambient air temperature the 315W will
operate in is 50°F/ 10°C, and the maximum air temperature is 100°F/ 38°C.
Electricity
The model 315W is supplied with a three prong power
cord to be plugged into a grounded wall outlet (See
Figure 2-2). The outlet should be on a branch circuit of
115 VAC, 60 Hz, single phase 15 amp, delayed action
fuse or circuit breaker. The 315W should be the only
device using that circuit.

INSTALLATION
Leveling
Note: This model must be leveled prior to installation.
There are four leveler legs on a model 315W, one at
each corner. To level the unit, turn the leveler legs
counterclockwise to raise the unit or clockwise to lower
the unit. (See Figure 2-5)
If the unit is to be built in, with the electrical outlet
behind the installed location, plug unit in and slide back
into position. Check for stability and adjust legs as
needed.
If unit is free standing, move it into place and check for
stability. Adjust legs as needed. Plug unit into an electrical outlet.
Initial Start-up
When the installation is complete, be sure to remove all
tape and packing materials before initial start-up.
Locate the temperature control knob on the bottom front
of unit. Rotate knob clockwise to an operating position.
(See Figure 2-6)
You should immediately hear a humming noise and feel
air blowing in and out of the vents near the knob. (See
Figure 2-7) After 10 minutes open the door and feel the
back panel inside the cabinet. It should feel cold to the
touch.
To switch refrigeration off, rotate the temperature control knob fully counterclockwise. The light will still be
operational.

Basic Operation
Loading
The six racks are designed to hold five bottles each
with the necks pointing toward the center. (See Figure
3-1) Two additional bottles may be placed sideways on
the bottom of the compartment for a total of 32. If large
bottles do not fit between the racks, remove an upperrack and place bottles on the rack below.
To remove a rack, remove the bottles on that rack, then
pull rack forward until it stops. Lift front of rack up while
pulling forward. After indentations on the wine rack
clear the rollers on the cabinet slides, lower front of
rack while continuing to pull forward and lifting rear of
rack out of unit.
NOTE: Loaded racks can be heavy. If several loaded
racks are pulled out at once, the unit could tip forward
unexpectedly.
Temperature Control
Rotate the temperature adjustment knob clockwise until
the desired temperature is achieved (See Figure 3-2).
Interior cabinet temperatures will be higher at the top
and front and cooler at the bottom. Place a thermometer in the compartment to check the temperatures.
Wine rack positions correspond to these temperature
ranges. The upper two racks will be the warmest, that
is where red wines would be placed. The middle two
racks are where the white wines would go, and the bottom area is where sparkling wines would be kept.
The recommended temperatures for “serving” wines
are:
• Red wines - around 60°F (16°C).
• Rosé wines - around 50°F (10°C).
• Sparkling wines - around 45°F (7°C).
NOTE: Air temperature inside the compartment will
fluctuate slightly as the cooling system cycles on and
off. In very warm room ambient conditions the unit may
run continuously.
NOTE: When initially loaded with room temperature
product, the 315W may operate continuously for as
much as 24 hours until the temperature inside the cabinet reaches the desired set-point.

MAINTENANCE
Little maintenance is required other than keeping the
unit clean. The evaporator at the back of the compartment is an off-cycle-defrost type. Any frost that develops during operation melts and drains away when the
unit cycles off. Water from the evaporator drains into a
pan at the bottom of the cabinet and evaporates into
the room air.
Routine Maintenance
The following procedures can be followed to ensure
proper operation of the 315W.
1. About once a year check the drain trough and hose
by pouring about a half-cup of water into it to be
sure it drains well. (See Figure 3-7)
2. The outside of the cabinet can be kept clean by
wiping it with mild soap and water.
3. The inside liner can be washed using any nonpetroleum based soap and water.
4. The glass door can be cleaned with any glass
cleaner.
5. The door gasket can be removed for cleaning by
pulling it out of its channel (See Figure 3-4).
6. The condenser should be vacuumed approximately
every 3 to 6 months to remove any dust or lint that
may have been drawn to it. To access the condenser, use a phillips screwdriver to remove the
kickplate. Then, use an accessory probe on the
vacuum cleaner hose to reach back into the left
side of the compressot area to remove any lint from
the front of the condenser fins. (See Figure 3-5
and Figure 3-6)
Figure 3-5. Remove Kickplate
Figure 3-6. Vacuum Fins
Figure 3-4. Door Gasket Removal
Take care to not damage the condenser fins. Doing
so will reduce the efficiency of the appliance.

Drain System Note
The 315W has an evaperator drain system below the
evaporator. Moisture will form on evaporator panel at
the back of the unit, then during off cycles this moisture
drains into a trough and down through a hose to the
drain pan. (See Figure 3-7)
The drain hose must be directly above the drain pan or
water may leak onto the base of unit (See Figure 3-8).

HFC-134a REFRIGERANT SERVICE INFORMATION
The sealed system contains HFC-134a refrigerant. This section gives some general rules for working with 134a,
and explains procedures to be followed while servicing the sealed system.
134a refrigerant requires synthetic Ester oil in the compressor, and does not tolerate contamination from
other refrigerants, moisture, petroleum-based lubricants, silicone lubricants, cleaning compounds, rust
inhibitors, leak detection dyes, or any other type of additive.
General Rules for Working with 134a Refrigerant
• Use equipment dedicated to 134a sealed system service only.
• Use only 134a refrigerant for back-flushing and sweep charging.
• Always replace the filter-drier when servicing the sealed system.
• The filter-drier must be cut from the sealed system. Never un-braze the drier as the heat will drive moisture
back into the sealed system.
• Do not leave sealed system nor replacement compressor open to the atmosphere for more than 10 minutes.
• When the rubber plugs are pulled from the service compressor, a release of pressure should be heard. If no
release of pressure is heard, do not use the compressor.
• Use ONLY virgin 134a refrigerant when recharging the sealed system.

SEALED SYSTEM OPERATION
The following six diagrams represent the basic model
315W sealed system. The components are listed in
order of refrigerant flow, with an explanation of their fundamental role as part of a sealed system.
Compressor (Figure 4-1)
The compressor creates a high and low side pressure
difference in the sealed system. When the compressor
piston pushes, compressing the refrigerant gas, it causing the refrigerant pressure and temperature to rise.
The high-pressure/high-heat refrigerant gas is pushed
out the compressor discharge tube to the condenser.
Condenser (Figure 4-2)
The high-pressure/high-heat gas travels through the
condenser tubing, where most of the heat in the refrigerant is drawn out and dissipated into the room by the
cooler ambient air that is being drawn over the condenser tubing (referred to as heat transfer). This
changes the gas into a high-pressure warm liquid
before it enters the high-side filter-drier.
Filter-Drier (Figure 4-3)
The high-pressure warm liquid travels through the highside filter-drier, where the desiccant pellets inside the
drier remove moisture from the refrigerant before it
enters the capillary tube.

#3758664 - First Edition - July, 2005
Capillary Tube (Figure 4-4)
The high-pressure warm liquid refrigerant travels
through the long skinny capillary tube which is soldered
to the suction tube (these two tubes soldered together
create the heat exchanger). (See Suction Tube & Heat
Exchanger below.) As the warm liquid refrigerant trav-
els through the capillary tube it gives up heat to the cool
refrigerant gas traveling through the suction tube and
the pressure drops, so it is a low-pressure/cool liquid
before it enters the evaporator.
Evaporator (Figure 4-5)
As the low-pressure/cool liquid refrigerant enters the
evaporator, it vaporizes. This is caused by a dramatic
pressure change, occurring when the refrigerant from
the smaller diameter capillary tubing enters the larger
diameter evaporator tubing. This refrigerant vapor travels through the evaporator, absorbing heat from the
compartment, gradually converting the refrigerant to a
cool gas. This cool refrigerant gas then enters the suction tube.
Suction Tube & Heat Exchanger (Figure 4-6)
The cool gas travels through the suction tube which is
soldered to the capillary tube (as mentioned earlier,
these two tubes soldered together create the heat
exchanger). As this cool refrigerant gas travels through
the suction tube it absorbs heat from the warm liquid
refrigerant traveling through the capillary tube, making it
a luke warm gas. The lukewarm refrigerant gas is
pulled back to the compressor (via vacuum force),
where the process begins again.

SEALED SYSTEM DIAGNOSTIC INFORMATION
NOTE: The temperature/pressure table at right is for reference only. A
unit's temperature/pressure correlation may differ from those listed due
to: set-points, where the sealed system is in the refrigeration cycle,
ambient temperature, etc.
If a unit is experiencing temperature problems, it is recommended to
reference the General Troubleshooting Guide before accessing the
sealed system. After all mechanical and electrical components have
been ruled out, sealed system pressures can be checked and compared against those listed in the tables below.
NOTE: Whenever entering the sealed system, always use solder
-on
process valves. Do NOT use bolt-on process valves as they are prone
to leak.
NOTE: Whenever servicing the sealed system, the high-side filter-drier
assembly must be replaced.
