Features and Specifications

• CELLARTEC split cooling systems CellarTec 1/8-1/2 Ton-SSL are
designed and used to provide a cold temperature between 50~65
properly insulated wine room at a normal environment.

• The wine room 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.

• SSL units consist of a condensing unit and an evaporator unit, and they
are connected by a liquid line and an insulated suction line.

• SSL condensing units can be located away from the evaporator units and
wine cellars as far as 50 feet, which will bring you quiet operation.

• SSL evaporator units provide low profile and whisper quiet operation. The
evaporator units can be installed on the ceiling in a wine cabinet or room.

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 R11

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 enclosure shall be sealed to prevent air and moisture
leakage into the room. Concrete, rock, and brick are not insulation or vapor
barriers.

Doors shall be of a minimum size, insulated to at least R11 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 enclosure by
more than 25 °F. No enclosure 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 enclosure 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 enclosure. Symptoms of
this condition are; 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 enclosure. Please be aware that moisture can pass
through solid concrete, paint and wood. Often a newly constructed room 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.

Installer’s Instruction

Federal law requires that CELLARTEC split cooling systems be

installed by an EPA certified refrigeration technician.

CELLARTEC split system is shipped as components and is ready for use only
after a certified refrigeration technician has properly installed, evacuated,
charged and tested the system. Proper installation is critical. Apex can only
warrant the quality of the components. The installation and proper operation of
the system must be warranted by the installer. Installation of the system must be
done in accordance with all state and local building and electrical codes.
The condensing unit and evaporator unit are connected by a liquid line and an
insulated suction line that are supplied by the installer. These lines must be
properly sized for the distance between the two units. After the units and the lines
are installed, the system must be pressure tested. If no leaks are found,
evacuate and charge system. Refrigerant amount will vary depending on the
length of line set.

1. Condensing Unit

• Place the condensing units WM150-650SCU in a
properly ventilated location. If it is not, heat exhausted
by the condensing unit will build up and the cooling
system will not operate properly.

• Condensing unit shall be elevated to avoid possible flooding and shaded
from direct sun. It shall not be exposed to temperatures higher than 110

°F or lower than 50 °F (optional low ambient kit available).

• Leave minimum 5 feet clearance for the exhaust side and leave minimum
1 foot clearance for the fresh air intake side.

CAUTION:
IF THE CONDENSING UNIT IS EQUIPPED WITH A LOW AMBIENT
CONDITION KIT, DO NOT TURN ON THE COMPRESSOR UNTIL THE
CONDENSING UNIT HAS BEEN POWERD FOR 24 HOURS.

2. Discharge/Suction Valve Operation (Condensing unit)

3. Evaporator Unit

• The WM15-65SFCL evaporator units shall be installed for ceiling mount
with the air supply towards horizontally and air return on the bottom.

• Supply air flow shall be unobstructed for at least 12” for free installation or
2” for deflector installation and return air shall be unobstructed for 6”.

• There is a gravity drain line and the unit shall be installed level or with a
slight angle toward the drain connection. If rise-up is needed, a
condensation pump must be used.

4. Thermostat and Air Sensor

CAUTION:
USE 18 GAUGE THERMOSTAT WIRE.

• The thermostat with a built-in air sensor can be installed in the wine room
5 ft above the floor in an area with good air circulation at average temp.

• If the thermostat is mounted outside the wine room, a remote air sensor is
required inside the wine room. The air sensor can be located in a well
circulated or in the return air area, but not the supply air or air dead area.

5. Piping, Evacuating, Charging and Starting

CAUTION:

• ALWAYS USE THE SUPERHEAT AND SUBCOOLING, PRESSURE

READINGS TO CHARGE REFRIGERANT PROPERLY, THE LISTED
CHARGES ARE FOR REFERENCE ONLY.

• CHARGE 15% MORE REFRIGERANT IN THE SUMMER IF THE UNIT IS

EQUIPPED WITH A LOW AMBIENT CONDITION KIT.

NOTES:

• THE VALVE CONNECTION SIZES OF CONDENSING UNIT AND THE LINE

CONNECTION SIZES OF EVAPORATOR UNIT ARE NOT NECESSARY
THE SAME AS THE ABOVE LISTED LINE SIZES.

• IF THE CONDENSING UNIT IS INSTALLED ABOVE THE EVAPORATOR

UNIT, USE THE SUCTION LINE ONE LISTED SIZE SMALLER.

• EXPANSION AND SOLENOID VALVES ARE INSTALLED ON LIQUID LINE.

• The installation order starts from condensing unit (including the receiver,

discharge valve), liquid line filter-drier, moisture-liquid indicator/sight glass,
liquid line, to evaporator unit (including liquid line connection, solenoid
valve, expansion valve, and suction line connection), returning to insulated
suction line, suction valve and then condensing unit.

- 10 -

• Charge the system after pipe brazing, leak testing and evacuating. Liquid
must always be charged into the hide side.

• Use inverted siphons to prevent liquid from flooding back to the
compressor and aid oil returning to the compressor.

• The subcooling at the condensing unit shall be around 10

°F. The charge

may be complete when there are no more bubbles forming in the sight
glass.

• Head pressure: 125-150 psig at 70-90

°F ambient temperatures.

• The evaporator’s constant pressure expansion valve is set around 35­40°F at factory. This pressure setting gives a dew point to maintain the
humidity for storing wine.

• Suction pressure: adjust the AXV to 30-35 psig.

• The temperature split across the evaporator shall be 8-10

°F at 55°F wine

room temperature.

• The superheat at the evaporator unit shall be around 9-18

°F under low -

high heat load at normal ambient temperatures.

• If the superheat is high, check the subcooling first to know if the refrigerant
charge is sufficient. If the charge is not sufficient, add more refrigerant. If
the charge is good, then increase the evaporator suction pressure by
turning the hex nut (5/16”) clockwise.

• If the superheat is low, then decrease the evaporator suction pressure by
turning the hex nut (5/16”) counter-clockwise.

The line sizes and refrigerant charges are listed as follows.

Care Guide

In general, always unplug system or disconnect power while doing care.

1. Coil Cleaning

• Clean the condenser coil regularly. Coil may need to be cleaned at least
every 6 months.

• Unplug the system or disconnect power.

• Use a vacuum cleaner with an extended attachment to clean the coil when it

is dusty or dirty.

• Plug cooling system or reconnect power.

2. Moisture Removing

• Remove the extra condensate if it is accumulated in the wine cellar at high
ambient temperature and humidity.
