Feature Description

• Wine-Mate split cooling systems VINO2500-6500SSR are 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.

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

• SSR 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 SSR evaporator units are designed for installation inside a wine rack or between two ceiling joists, making them an ideal choice for small and medium wine rooms.

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 WINE-MATE split cooling systems be installed by an EPA certified refrigeration technician.

WINE-MATE split 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 WM250-650SCU 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 45 ° F (optional low ambient kit for 20 ° F).

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

1 foot clearance for the fresh air intake side.

2. Evaporator Unit

• The WM25-45SFCR evaporator units shall be installed for rack mount with the air supply from the left front, top or side and air return on the right front, top or side.

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

• 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.

3. Air Sensor

• The air sensor can be located in the wine room or the return air area, but not the supply air area.

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, 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.

• 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.

• 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 ° F under low and high load at 75 ° F ambient temperature.

• 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.

• Low side pressure: 33-35 psig

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

Temperature Control & Humidity Adjustment

1. Temperature Setting

Set the temperature at 55

°

F for the optimum aging of wine

On initial start-up, the time required to reach the desired temperature will vary, depending on the quantity of bottles, temperature setting and surrounding temperature.

Allow 24 hours to stabilize the temperature for each new temperature setting operation

2. Use of the VTSTAT controller

NOTE: Use the dial number for “Medium Temp”

Fig. 3.1 VTSTAT

Fig. 3.2 Default Dip Switch Setting

Dip-switch description (See detail in VSTAT instruction )

1, 2 differential: added to the Set Point, establishes the temperature threshold, measured by the regulation probe, beyond which the compressor is activated;

3 compressor safety function: OFF - function disabled; ON - function enabled;

4 temperature display: OFF - displayed in °C; ON - displayed in °F;

5,...,8 duration of defrost/defrost termination temperature: if the defrost sensor is utilized, these dip-switches select the defrost termination temperature, otherwise they select the defrost duration;

9 type of defrost: OFF - resistance defrost, ON - hot gas defrost.

1) Set Point

Rotate the circular selector in correspondence with the arrow placed nearby. The selector represents 14°F to 68°F (-10°C to +20°C) for medium temperature models. “10” is the coldest setting, “1” is the warmest. Use the medium temp setting and place the dial at number 3.

2) Differential

It is possible to modify the differential from 1°F minimum to 12.5°F maximum.

Simply shift the first two dip-switches to the ON or OFF position according to the wanted value.

3) Defrost management and setting

A defrost can be activated manually, by pressing the “man. def.” button, or cyclically, the interval set by the “def.intvl” rotary switch at the top left with respect to Set Point selector. The interval can be selected from 1 to 12 hours in 1 hour steps. If the selector is positioned on the “0”, the cyclic defrost is disabled.

Note: manual defrost reinitializes the time required for successive cyclic defrosting. The selections are effective beginning from the successive cycle. For an immediate effect, it is necessary to turn power to the VTSTAT off for a few seconds.

It is possible to choose between an electric defrost (the compressor is deactivated and the defrost relay is activated) and a hot gas defrost (both the compressor and the defrost relay are activated); The defrost termination, can take place by time (from 1 to 60 min.) or by temperature (from 0 to 86°F) if the defrost sensor is utilized for the correct programming). If the defrost sensor is disconnected, interrupted or breaks down for any reason, the defrost terminates after a maximum time of 90 minutes if it is resistance-based, or 40 minutes if it is hot-gas based.

The instrument stores the defrost state every 15 minutes to allow restart after power loss.

4) Compressor safety function

If the function is enabled, a minimum three minute interval is ensured between deactivation and successive restart of the compressor.

If the function is enabled, the compressor is not energized for three minutes after controller power up.

The function is also active in hot-gas defrost mode.

5) LED & Display Messages

1. Compressor and defrost deactivated

3. LED blinking 0.5s on/0.5s off
