OM-DROP-IN SERIES 7
Installation
SELECTING A LOCATION FOR YOUR NEW UNIT
The following conditions should be considered when selecting a location for your unit:
1. Floor and Countertop Load: The area on which the unit will rest must be level, free
of vibration, and suitably strong enough to support the combined weights of the unit
plus the maximum product load weight.
2. Secure and Seal: Once the drop in unit is installed into the counter it can be
secured to the countertop by using the brackets supplied from the factory.
a. Secure unit to top and seal with “NSF” approved silicone.
b. Install inside duct with thumb screws and adjust outside duct to fit between
condenser coil and counter’s louvered cutout
c. Secure outside duct in place with screws through pre-punched holes.
3. Clearance: See installation diagrams for minimum compartment dimension. Do
not place any object that can block the ventilation exhaust from the machine
compartment register. 10 inch clearance at each of the louvered ends of the unit.
Area of equipment must be free of all combustible materials.
4. Ventilation: The air cooled self contained unit requires a sufficient amount of cool
clean air. Avoid surrounding your unit around other heat generating equipment and
out of direct sunlight. Also, avoid locating in an unheated room or where the room
temperature may drop below 55°F or rise above 86°F.
INSTALLATION CHECKLIST
After the final location has been determined, refer to the following checklist prior to
start-up:
1. Units must be installed in a minimum compartment size as indicated in the
installation drawing. Provided louvers must be installed in accordance with the
installation drawings to ensure proper ventilation for system operation or in the event
of a refrigerant leak. NOTE: It is recommended that ONLY a single GFCI outlet be
located in the compartment where the unit is installed. No other arching potential
components are allowed.
2. Follow cut out dimensions provided for specific models to properly size the opening
for your drop in.
3. Check cord and plug of unit to assure no damage has occurred to these components.
4. Check all exposed refrigeration lines to ensure that they are not kinked, dented, or
rubbing together.
5. Check that the condenser and evaporator fans rotate freely without striking any
stationary members.
6. Plug in unit and turn on main on/off power button on the controller.
7. Allow unit time to cool down to temperature. If temperature adjustments are required,
the control is located on the front panel. Confirm that the unit is holding the desired
temperature.
IT IS IMPORTANT THAT A VOLTAGE READING
BE MADE AT THE COMPRESSOR MOTOR
ELECTRICAL CONNECTIONS, WHILE THE UNIT
IS IN OPERATION TO VERIFY THE CORRECT
VOLTAGE REQUIRED BY THE COMPRESSOR
IS BEING SUPPLIED. LOW OR HIGH VOLTAGE
CAN DETRIMENTALLY AFFECT OPERATION
AND THEREBY VOID ITS WARRANTY.
CAUTION!
THIS UNIT CONTAINS R290 FLAMMABLE
REFRIGERANT. USE CAUTION WHEN
HANDLING MOVING AND USE OF THE
REFRIGERATOR OR FREEZER. AVOID
DAMAGING THE REFRIGERANT TUBING OR
INCREASE THE RISK OF A LEAK.
FAILURE TO FOLLOW INSTALLATION
GUIDELINES AND RECOMMENDATIONS MAY
VOID THE WARRANTY ON YOUR UNIT.
IT IS IMPORTANT THAT YOUR UNIT HAS
ITS OWN DEDICATED LINE. CONDENSING
UNITS ARE DESIGNED TO OPERATE WITH
A VOLTAGE FLUCTUATION OF PLUS OR
MINUS 10% OF THE VOLTAGE INDICATED
ON THE UNIT DATA TAG. BURN OUT OF A
CONDENSING UNIT DUE TO EXCEEDING
VOLTAGE LIMITS WILL VOID THE WARRANTY.
THE DANFOSS CONTROLLER HAS LOW
VOLTAGE PROTECTION AND WILL NOT
OUTPUT VOLTAGE TO THE COMPRESSOR IF
VOLTAGE IS LESS THAN 104V.
THIS UNIT IS INTENDED FOR USE IN
LABORATORIES IN COMMERCIAL,
INDUSTRIAL, OR INSTITUTIONAL
