Installation Instructions
Caution: A qualified technician must install this refrigeration equipment. Please read, understand, and
follow all instructions in this manual prior to start up. Failure to install and adjust this refrigeration unit in
compliance with these instructions will void the warranty.
This unit is suitable for use with R-22 and Icor International’s NU-22B and other R-22 replacements such
as Arkema’s R-427A or DuPont’s R-438A (MO99). We suggest using NU-22B for the following reasons:
It is about 2% to 5% more efficient than R-22
ASHRAE Designated and safety classified A1: Nontoxic/Nonflammable
EPA Snap listed
Non-Ozone Depleting with Low Gl obal Wa rming Impact
Compatible with all standard refrigeration oils so no oil change is necessary
R-22 like properties over a broad range
Low discharge temperatures
Stocking distributors nationwide
The refrigerant oil in the unit must be replaced with a like volume of POE oil when using R-427A,
R-438A and other blended refrigerants. Multiple oil changes are not necessary.
A temperature pressure chart for R-22, NU-22B, R-427A and MO99 can be found on page 26.
1. Select a suitable location for the evaporator with respect to air circulation, drain, refrigerant and electrical
lines. Adequate air circulation requires a 36” clearance in front of the unit, do not place any obstruction in
front of the evaporator. Do not attempt to duct this evaporator. Before installing any unit, the installer must
determine that the wall or ceiling can safely support the weight of the unit. Provide adequate clearance for
maintenance. Check local codes for additional precautions. The face of the evaporator should be within 4”
of the front of the racking, if placed in double deep racking you must bring the evaporator forward so it is
within 4” of the front of the rack.
2. Place the condenser at the desired location outside the wine cellar in a well-ventilated area or outdoors.
Indoor condensers must be placed in a space twice the volume of the wine cellar to prevent excessive
condensing temperatures. Check local codes for proper venting of mechanical rooms. Field supplied
vibration absorbing mounting pads and insulated compressor jackets effectively reduce noise transmitted
by the unit. Condenser face must be at least 12” from any obstruction and entering air must not exceed 110°
F. When installing an outdoor condenser, be sure that it is located so that leaves or snow do not accumulate
and block the airflow. This can be accomplished by setting the condenser on a concrete slab, blocks, etc.
Place the unit so prevailing winds do not blow rain, snow and debris into the open ends of the outdoor
cover. Avoid placing the outdoor condenser in direct sunlight, especially in warm climates. Condenser air
directed toward or away from the dwelling may cause undesirable noise for owners and their neighbors.
This must be considered when placing the unit outdoors.
3. Using a silver/phosphorus/copper alloy with between 5% and 15% silver, braze the refrigerant line set to
the evaporator and condenser with nitrogen flowing through the lines to eliminate carbon deposit build up
on the inside of the joints which could contaminate the refrigerant and restrict the drier and expansion
valve. To do this, open the system service ports. This will purge the nitrogen holding charge in the system.
Connect a nitrogen bottle to one valve and set pressure regulator to about 2 PSI. A small amount of
nitrogen will flow out the other valve.
You must install the line set according to Table 1 on the following page. Failure to do so voids the
warranty. The evaporator and/or condensing unit may have different fitting sizes than the line set, so field
supplied reducers are necessary. Run the line set according to Table 1, and reduce at the condenser and
evaporator connections.
WZDS9100 #2

Maximum line length is 200 equivalent feet. Long sweep elbows and any bends in soft copper are
equivalent to 5 linear feet. Line lengths in excess of 200 equivalent feet may cause compressor damage and
will void the warranty. Example: To determine the equivalent length of the line set add up the linear feet of
suction line. Multiply the number of elbows required and add it to the total length of suction line.
Example:
Horizontal pipe 40 linear ft.
Vertical pipe 10 linear feet
8 elbows x 5 40 equivalent feet
Total equivalent feet 90 equivalent feet
Following Table 1 and guidelines for vertical risers below, the correct line set size is 3/8” liquid line and
3/4” suction line. The 10 linear feet of vertical suction line is 5/8”
Proper piping practices must be followed. The line set must be securely fastened to the building structure
for its entire length. The suction line must be insulated the entire length of the run. Horizontal line runs
must slope 1/2” per 10’ towards the condenser for proper oil return. No dips, sags or other low spots that
will trap refrigerant oil are permitted. This prevents starving and slugging the compressor with oil. We
highly recommend using rigid copper for this reason.
For systems with condensers 10 feet or more above the evaporator, reduce the suction line size by one. For
example, 5/8” line changes to 1/2” and 7/8” changes to 3/4” for the vertical section of the line only. Install
a P trap at the bottom of the riser of the same size as the horizontal piping.
Line sets up to 80 equivalent feet will use 3/8” liquid line and 5/8” suction line.
Line sets 81 to 200 equivalent feet will use 3/8” liquid line and 3/4” suction line.
Line sets longer than 200 equivalent feet will void the warranty. Minimum line set length is 15 linear
feet.
Table 1
Line set sizes may differ from system component fitting sizes so field supplied reducers are necessary. Run
the line set according to Table 1, and reduce at the condenser or evaporator if necessary.

For outdoor units, cut or drill a hole through the most convenient stationary side of the condenser cover large
enough for the line set to easily pass through. Cut the hole above the height of the compressor. Do not run
the line set through the bottom of the unit or the air grilles at either end. Do not run the line set through a
panel that moves when the lid is opened.

Rule of thumb: Once the suction line leaves the evaporator and turns downward, it cannot turn and
go back up to get to the condenser. The only time a trap in the suction line is acceptable is at the
bottom of a 10’ or taller riser.
4. Install the filter dryer and sight glass, if not already factory installed. Wrap with a wet rag to prevent over
heating during brazing.
5. Perform leak test with dry nitrogen, but never expose the system to leak test pressures greater than 150
PSI. Test all fittings including factory installed flare fittings on condenser and evaporator that may
have loosened during shipping. Leaks on unit(s) from a result of loose valves, interconnecting fittings,
and/or field piping are not covered by the warranty. It is the installer’s responsibility to locate and repair
all leaks prior to start up.
6. Evacuate the system to 1000 microns for 1 hour.
7. Install electrical wiring according to the Electrical Requirements on page 14 and the appropriate wiring
diagram. Follow all applicable codes.
8. After isolating the vacuum pump from the system, break the vacuum to a positive pr essure using refrigerant
connected to the liquid line. Add approximately 20 psi of refrigerant vapor. Do not start unit for the
first time with a full charge. Adding more refrigerant prior to start up will damage the compressor.
Always charge NU-22B and other blended refrigerants in liquid state.
WZDS9100 #2

9. Apply power to units for 24 hours prior to start up to allow crankcase heater to warm the
compressor and then start the unit. Complete the charging process with the compressor running and add
the balance of the charge into the suction line of the system. Liquid refrigerant should never enter the
compressor directly. Use a metering device to prevent slugging when charging with liquid.
10. The ICM333 Head Pressure Control is factory set to maintain approximately 225 psi head pressure. Verify
the head pressure remains at 225 psi or above. See page 22 and the charging table on page 23 for
instructions on how to adjust the fan speed controller. Never adjust the pressure control to bring on the
condenser fan motor above 250 psi. Slowly add refrigerant until the bubbles in the sight glass d isappear.
The condenser fan motor must be running to complete the charge
11. For R-22: After the system has run for 10 minutes check the sight glass again. During normal operation
with R-22 there should be no bubbles in the sight glass. If bubbles are present, the system is low on
refrigerant. Add refrigerant to eliminate the bubbles. Charge the system to approximately 5 of sub-
cooling. To calculate sub-cooling for R-22 subtract the liquid line temperature from the saturation
temperature corresponding to the head pressure. Measure the liquid line temperature between the receiver
and filter drier with and an accurate, digital, thermocouple style thermometer.
For Nu22B or other blended refrigerants: Some bubbles may be present with a full charge of a blended
refrigerant. Charge the system to approximately 5 of sub-cooling. To determine sub-cooling for NU-22B
or other blended refrigerants, subtract the liquid line temperature from the bubble temperature
corresponding to the head pressure. Measure the liquid line temperature between the receiver and filter
drier with an accurate, digital, thermocouple style thermometer.
12. Allow the wine room temperature to fall to 55F. Check the super heat at the evaporator. Measure the
suction pressure at compressor access port. From refrigerant pressure-temperature tables, determine the
saturation temperature (for R-22) or the dew temperature for NU-22B or other blended refrigerant at the
observed suction pressure. Measure the suction line temperature at the compressor. Subtract the saturation
temperature (Dew temperature for blended refrigerants) from the measured suction line temperature. The
difference is the superheat. Refer to the temperature pressure chart on page 26 in these instructions.
The superheat should be 8 to 16F. If the superheat is not in this range, the thermostatic expansion valve
must be adjusted. To adjust the expansion valve, remove the seal cap from the bottom of the valve. Turn
the adjustment screw clockwise to increase superheat and counterclockwise to decrease superheat.
Caution: There are 10 turns on the adjustment stem. When stop is reached while turning the
superheat adjustment stem, any further turning will damage the valve. One complete 360 turn
changes the superheat approximately 3-4F. As much as 30 minutes may be required for the system to
stabilize after the adjustment is made. Replace and hand tighten the seal cap. Always replace the
evaporator face plate between TXV adjustments.
13. Perform the final check of the refrigeration unit. The cellar temperature must be between 53 and 58 F.
Check the sight glass and gauge readings again. The super heat must be 8-16 F (see step 12). The hot gas
line temperature must not exceed 260 F. Never exceed the maximum amp draw (RLA) for the
compressor. Adjust the TXV, and charge as necessary. All measurements should be taken with the
condenser fan motor running. All temperature readings should be taken with a digital probe style
thermometer.
14. If the recommended system pressures and temperatures cannot be achieved, refer to the troubleshooting
chart on pages 24 and 25.
15. Clearly mark the unit to identify the refrigerant used.

Installation of the Indoor Unit
Firmly secure the evaporator mounting plate on a wall strong enough to withstand the weight of the unit. The plate
must be level and allow for the clearances shown in the figure above. The evaporator must be installed in such a way
as to prevent short cycling of the discharge air with the return air. Adequate air circulation requires a 36” clearance in front of the unit;do not place any obstruction in front of the evaporator. The face of the
evaporator should be within 4” of the front of the racking, if placed in double deep racking you must bring the
evaporator forward so it is within 4” of the front of the rack. Do not place the unit in direct sunlight, or above a door
or window. Do not attempt to duct this evapor ator. The location must also be suitable for refrigerant piping and
condensate drainage. The evaporator discharge air must not blow on the thermostat.
The refrigerant piping can be routed to the unit in a number of ways. Number 2 in the diagram below indicates a
cutout in the unit casing. Using the cutout will leave the refrigerant piping, condensate d rain, and electric exposed
in the cellar and should be avoided. Numbers 1 and 3 indicated below, are fo r piping routes that will leave the
refrigerant lines, drain and electric concealed, and should be used for the most attractive installation. A single, 2¼”
or 2 ½” hole will accommodate the passage of the line set, drain and electric through the wall. Slope the hole
downward through the wall and fasten the drain line to the bottom of the line set for proper drainage. These hole
locations are indicated on the mounting plate drawings as well. The refrigerant piping may be gently bent or twisted
to use any of the indicated pipe routes.
When the line set will be run on the inside
of the wall before the drywall is hung, use
the suggested route (route number 1).
Route number 1 is the preferred route.
Route 2 will leave the refrigerant piping,
electric, and drain exposed. For installations
where the line set will be accessible on the
backside of the wall, the alternate route
(route 3) can be used. Use caution when
using route 3. Secure the piping above the
bend before turning the piping to use
route 3 to prevent kinking the suction
line.

The indoor drainpipe must slope downward and have no traps. The drain must be fastened to the bottom of the
refrigerant lines. The drain requires an air gap to flow properly. Place the two hooks at the rear top of the
evaporator to hang the unit from the upper edge of the mounting plate. Ensure the hooks are properly seated on the
mounting plate by sliding the unit to the left and right. Gently press on the bottom face of the evaporator to snap the
bottom of the evaporator into place on the mounting plate.
The face of the evaporator casing can easily be removed. Screws are concealed under plastic covers on the bottom
leading edge of the unit, under the air discharge louver . Remove the covers to expose the screw heads an d remove
the screws. Remove screws above the air discharge under the hinged filter cover. Pull out and lift the botto m of the
evaporator casing to uncover the electric hook up.
After installation, properly seal the hole(s) where the refrigerant, drain and electric lines penetrate the wall
or ceiling. Failure to do so may result in uncontrolled condensation and water damage.
Evaporator Electric
Securely fasten the ground wire to the terminal with the green or green and yellow striped wire. The other two wires
on the evaporator terminal block receive 230 volts from terminals marked EVAP on TB1 in the condenser control
panel.

The holes shown are the best locations to route the refrigerant lines, condensate drain, an d electric. For installations
where the line set will be accessible on the backside of the wall, use the alternate route. When that is not possible,
and the line set will be run inside the wall before the drywall is installed, use the suggested route. This will leave the
flare connections exposed so they can be connected after the walls are finished.
Use caution when using the alternate route. Secure the piping above the bend before turning the piping to
prevent kinking the suction line.

Humidifier Installation
Install the Wine Guardian® Freestanding Humidifi er. Ru n
the humidifier prior to installation as the warranty does not
cover removal of the unit. Please read and understand the
owner’s manual and installation instructions prior to start
up. Follow the manufacturer’s manual to locate and mount
the free-standing humidifier. Install the hot water line and
drain according to the manufacturer’s instructions.
Disregard wiring instructions that include humidistat
wiring. The Wine Guardian® humidistat and transformer
are not necessary when used with the WineZone thermostat.
Cut off the plug end of the 24 volt control wire on
humidifier and connect the wires directly to the terminals
marked HUM on TB2 in the condenser control panel.
Do not install the humidifier directly underneath the
evaporator. Do not install the humidifier where the
evaporator will blow directly on the humidifier.

Condenser Fan Speed Control
The WineZone condensing unit uses an ICM333 fan speed
controller to maintain the proper head pressure.
When the condenser fan motor starts running it will start for a
length of time dictated by the hard start dial setting. After the
hard start time has elapsed, the motor speed is controlled by
the pressure transducer reading. The green light turns on
when the motor runs at full speed.
As the sensed pressure decreases, the output voltage
decreases. The yellow light turns on during motor variable
speed . The output voltage may decrease to the determined
cutout speed dictated by the cutout speed dial. Upon
reaching the cutout speed setting, the output voltage goes to
zero volts and the yellow light turns off.
The fan cut out speed is factory set to the minimum speed for sleeve bearing motors.
The fan hard start time is factory set to the minimum for sleeve bearing motors.
Adjust the set point dial to maintain 225 psi head pressure when the condenser ambient is at or below 70º F. The
control will maintain condenser pressure between 20 psig ab ove and 20 psig below dialed Pressure Setpoint.
The ICM Pressure Transducer is located on the receiver backseat valve. The backseat valve must remain
open 1/2 to 1 full turn to allow the pressure transducer to sense the head pressure.
Make sure that supply voltage to the system and ICM333 Head Pressure Control are disconnected before
installation or service.

Installation Check List
1. Ensure the electric voltage, breaker and wire size are correct for all electrical components.
2. Make sure the line set is less than 200 equivalent feet in length, the proper diameter and contains no oil
traps.
3. Make sure the line set has passed a leak test and has been evacuated below 1000 microns.
4. Check the evaporator drain and make sure it is clear of obstructions, free of traps, and has sufficient slope.
Quick Start Procedure
Caution: A qualified technician must install this refrigeration equipment. The following quick start
procedure is not a substitute for proper installation techniques and procedures. Please read, understand,
and follow all instructions in this manual prior to start up. Failure to install and adjust this refrigeration
unit in compliance with the installation instructions will void the warranty.
1. Break the vacuum to a positive pressure of approximately 20 PSI. DO NOT start the unit for th e first time
with a full charge.
2. Apply power to the unit for 24 hours to allow the crankcase heater to warm the compressor.
3. Start the unit.
4. Slowly add charge to system through the compressor suction access port. DO NOT allow liquid refrigerant
to directly enter the compressor. Use a metering device to prevent liquid from directly entering the
compressor. Always charge blended refrigerants in liquid state.
5. Adjust the condenser fan cycle control to maintain 225 PSI head pressure with condenser ambient
temperatures at or below 90º F.
6. Continue to add refrigerant until the sight glass is clear.
7. Allow the unit run and cool the room to 55º F.
8. Compare the saturation temperature corresponding to the suction pressure at the compressor to the sensible
suction line temperature at the compressor. Adjust the thermostatic expansion valve as necessary to ensure
a superheat of 8º to 16º.
9. Add refrigerant to maintain approximately 5º of sub-cooling.
10. Check the discharge (hot gas) line temperature midway between the compressor outlet and condenser coil
inlet. It should never exceed 260º.
11. Check the compressor amp draw. It should never exceed the RLA on the condensing unit rating plate.
12. Disconnect refrigerant gauges.
13. Clearly mark the unit to identify the refrigerant used.
14. Record the collected values on the Diagnostic Sheet and submit it to Wine Cellar Innovations for review.
