KoolR Cooling Units

 

LOCATION:

Consider from the beginning that the cooling unit will be installed through the wall, close to the ceiling of your room and MUST vent the warm air into an adjacent, air-conditioned fairly large interior space. Do not even think of venting to the garage, or using any ducting for the air streams. The airflow has to be totally unobstructed, keep in mind that up to 200 cubic feet of air will be vented every minute.

KoolR cooling units must be installed precisely as directed in the Manual. DO NOT attempt to install this unit before reading the Manual!

DO NOT INSTALL THIS UNIT THROUGH AN EXTERIOR WALL! Koolr units must ventilate to an adjacent INTERIOR space, NEVER to OUTDOORS! The area in which Koolr vents its warm air must be completely unobstructed.

DO NOT install this unit in an enclosure where ANY surfaces are uninsulated or unprotected by vapor barrier. Especially in basement or other below-grade locations, ALL surfaces (walls, floor and ceiling) must be insulated to at least R-20 and protected by vapor barrier on both sides. Uninsulated concrete floors will radiate heat and humidity during summer months, forcing the unit to work much harder than necessary, WILL shorten the life of the unit, AND WILL PRODUCE EXCESS CONDENSATION.

The Digital Sensor, which is encased in a red vinyl cap and permanently mounted on the front of the unit, must not be modified or handled. The Sensor will read and respond to changes in AIR temperature in the enclosure, to ensure most efficient operation and ideal storage temperature control. DO NOT attempt to modify the sensor to read liquid temperature.

Koolr units must be cleaned as directed, at least 4 times a year, or more frequently if located in a dusty area. DO NOT install the unit in a location where the condenser (warm side) coil is not accessible for periodic cleaning.

Koolr cooling units must be supplied by a dedicated, separately-fused and grounded 15-Amp 115 Volt line. The line must not be shared with any other outlet or appliance. If an extension cord must be used, it must be rated for at least 15 Amps. Before operating Koolr cooling units , have the output tested and verified. If the line delivers less than 105 Volts, do not attempt to operate your unit. If the supplied voltage is insufficient or if intermittent shorting occurs, the unit may be unable to start its compressor, and the LED display may be corrupted. Before requesting warranty service for these problems, test and verify the voltage output. You might also try plugging the unit into a different circuit, and see if it performs differently. The electronic controller must also be protected against sudden power surge. Use a good quality surge suppressor. If the power source is prone to significant “noise” or interference, it may be advisable to use a good quality power line conditioner. As with any sensitive electronic device, Koolr cooling systems may be damaged by power surges or spikes, sudden interruptions or prolonged low-voltage conditions. You must monitor the unit on a daily basis. If there is an apparent problem or “Alarm” condition, you must disconnect the power supply to avoid potential damage to your wine collection. If unable to correct the problem through consultation with our Trouble-shooting resources, contact Customer Service. Be advised that Shanghai Koolspace Co. Ltd.  cannot in any event be liable or responsible for incidental or consequential damages.
This unit is not designed for COMMERCIAL USE. Such usage will void any warranty. In addition, Third party servicing of these units during the warranty period will void the warranty.

GENERAL:

Select a suitable area, sized appropriate to the model’s capacity, in a location where ambient temperatures will not exceed the desired storage temperature by more than 25ºF (14ºC). This appliance is for INDOOR USE ONLY, and must not be vented to a laundry room or similar which traps warm air. The unit must be vented to an adjacent interior room (never to outdoors), and should mounted reasonably close to the ceiling. Exhaust air must not be obstructed in any way. The temperature of the air in the immediate area where the unit vents it's warm air must never exceed 80ºF with 70% R.H. (non-condensing).

Operating temperatures are:

  • for cold side: minimum 50ºF (10°C) and maximum 70ºF (21°C).
  • for hot side: minimum 65ºF (18°C) and maximum 80ºF (26°C) at maximum 70%R.H.

 

WARNING: LOWER SET TEMPERATURE FROM DEFAULT 57ºF (14ºC) ONLY IF AMBIENT CONDITIONS ALLOW. A LOWER SET TEMPERATURE CAN CAUSE WATER LEAKS OR OVERFLOW IN HIGH HUMIDITY CONDITIONS.

INSULATION:

Floor, ceiling and all walls of the enclosure must be insulated to minimum R-20 rating, although R-30 is recommended. Best material is foil-backed urethane foam, sealed at all joints with thermal tape. Build a proper sub-floor with vapor barrier, and insulate to at least R-20, especially if floor is concrete.

VAPOR BARRIER:

All surfaces of the enclosure must be protected by a proper vapor barrier, ideally on both cold and warm sides.

SEAL:

Seal corners, joints, gaps, vents, electrical outlets and switches, and especially around door and frame, to achieve airtight seal. Pack larger gaps with insulation. Seal all with silicone caulking. Seal drywall with odorless waterproof paint.

POWER SUPPLY:

This appliance must be installed in accordance with national wiring regulations. Do not use if the power cord is damaged; it must be replaced by the manufacturer or its service agent or a similarly qualified person in order to avoid a hazard. Plug must remain accessible after installation. 
Electrical service must be a dedicated, separately fused and grounded 15 Amp, 120V line. Do not share the circuit with any other appliance. If extension cord must be used, it must be rated for 15 Amps. Test line voltage BEFORE operating, and do not use if line voltage is less than 105V. The unit must be protected against power surges and spikes: use a good quality surge suppressor.

WALL CUTOUT:

The hole size is 15 3/4" x 9 1/2" for KoolR Piccolo and KoolR Magnum .Click here for more info  

DOOR:

A good door with a high insulation value and no air leaks is also required. keep the door usage low, the cooling unit is not designed for COMMERCIAL USE.

ENVIRONMENT:

Assure a clean environment for the cooling unit, otherwise the coils will be soon covered with dust, grease or any other contaminants, reducing their performance. Even in a clean environment a unit must be cleaned (coils have to be vacuumed) at least 4 times each year. For more information, please go to maintenance. Fungus and mildew growth and build-up is a natural process in a humid wine cellar, that can lead in some extreme cases to a clogged drain line. To clean, remove drain barb or hose. Clean opening gently, with a screwdriver. Other solutions are covered under excess condensation.
