Feature Description

Wine-Matesplit cooling systemsVINO2500-8500SSHare designed and used to provide a cold temperature between 50~65°F for a 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.

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

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

The SSH evaporator units are designed to provide chilled air to wine rooms through ducts and can be located up to 25 ft away to reduce noise.

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-ladenair 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 WINE-MATEsplit cooling systems be installed by an EPA certified refrigeration technician.

WINE-MATEsplit system is shipped as components and is ready for use only after a certified refrigeration technician has properly installed, charged and tested the system. Proper installation is critical. Vinotemp 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 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 with R134A. Refrigerant amount will vary depending on the length of line set.

1. Condensing Unit

Place the condensing units WM250-850SCUin 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.

Leave minimum 5 feet clearance for the exhaust side and leave minimum

1 foot clearance for the fresh air intake side.

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 45°F (optional low ambient kit for 20°F).

2. Evaporator Unit

The WM25-85SFCHevaporator units can be installed outside a wine room.

Supply and return air flow from the evaporator unit shall be unobstructed for at least 1 foot.

There is a gravity drain line so that it can not be installed above the evaporator unit. Otherwise a condensation pump must be used.

If the overall duct length is more or less than 50ft, it is necessary to check the air flow to meet the specified CFM. It may use larger or smaller size ducts or fan speed control to adjust the system refrigeration performance to achieve 8-10°Fdifferential between return air and supply air.

3.

Air Sensor

The air sensor is recommended to place in the wine room. If it is in a

 

return duct, due to the temperature differential the temperature setting

 

needs to be adjusted in order to maintain the proper wine room

 

temperature.

4.

Refrigeration Piping and Charging

NOTES: ALWAYS USE THE SUPERHEAT AND SUBCOOLING, PRESSURE READINGS TO CHARGE REFRIGERANT PROPERLY, THE LISTED CHARGES ARE FOR REFERENCE ONLY.

The installation order starts from condensing unit (including the receiver), liquid line filter-drier,moisture-liquidindicator (sight glass), liquid line, evaporator unit (including liquid line solenoid valve and thermostatic expansion valve or automatic expansion valve), suction line, and returning to condensing unit.

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.

-8 -

The evaporator’s constant pressure expansion valve is set around 38-

40°F at factory. This pressure setting gives a dew point to maintain the humidity for storing wine.

The superheat at the evaporator unit shall be around 9-18°Funder low and high load at 75°F ambient temperature.

Low side pressure: 33 psig

High side pressure: 130 -150psig at 75-90°F ambient temperatures
