Installation
Safety instructions
• Only plug into a grounded outlet
• Do not remove ground prong
• Do not use a 3 prong to 2 prong adapter
• Do not use an extension cord
• Disconnect power before servicing
• Do not operate with any panels or parts removed
Location
1. Measure all doorways and passageways for clearance before moving cabinet. These units
will pass through a standard 30" x 84” door opening.
2. Inspect the interior, exterior and mechanical equipment for special instruction tags
fastened at various points.
3. Move the unit into the desired location. Make sure the bottom is evenly supported and the
floor is level. Thin shims under the points of rest can be used to equalize the distribution
of weight. If the cabinet sets on an uneven floor, a slight rocking or vibration might result
when the condensing unit is set in operation.
4. A minimum of 6" clearance is required at the back and sides of the unit, and 12” on top of
the unit to allow adequate ventilation of the mechanical equipment.
Note
• All units are provided with locking casters. Apply the brakes prior to operation.
• Do not position the equipment in direct sunlight, near heating diffusers, radiators, or
other sources of heat. The ambient temperature range at the location must be 59°F to 90°F
(15°C to 32°C).
• Do not position the unit in a way that impedes access to the switch on the back of the
unit.

Explosion Hazard Keep flammable materials and vapors away from refrigerator. Failure
to do so can result in death, explosion, or fire.
Wiring
CAUTION Operation under electrical conditions other than those specified on the
dataplate will cause permanent damage to the mechanism. The dataplate is
located inside the refrigerator at the top of the right hand wall.
Before connecting your freezer to a power source, be sure to check the dataplate for correct
voltage. Standard NEMA plugs are provided with all units.
WARNING For personal safety and trouble-free operation, this unit must be properly
grounded before it is used. Failure to ground the equipment may cause
personal injury or damage to the equipment. Always conform to the
National Electrical Code and local codes. Do not connect unit to already
overloaded power lines.
Always connect the equipment to a dedicated (separate) circuit. Electrical codes require fuse or
circuit breaker protection for branch circuit conductors. Use time delay fuses for #12 AWG
circuits.
CAUTION Do not use an outlet that can be turned off by a switch.

Initial Startup
• Make sure that the unit is free of all wood or cardboard shipping materials, both inside
and outside.
• Plug unit into a power outlet on a dedicated circuit.
• Turn unit on using power switch on the back of the unit. Turn unit off using power switch
before unplugging or servicing.
• Allow unit to reach operating temperature before storing contents.
Refrigerator Section Performance
The refrigerator section is factory preset to operate within a +2 ºC to +4 ºC temperature
range. The refrigerator section temperature will be shown on the digital display at the top of
the unit.
Freezer Section Performance
Ther freezer section setpoint is factory preset and will vary based on ambient conditions.
Typical performance:
Ambient Temperature Freezer Temperature
15 ºC-32 ºC
25 ºC-26 ºC
32 ºC-20 ºC
The freezer setpoint cannot be changed.

Operation
Defrost
10 Installation and Operation Thermo Scientific Jewett PRF17 Refrigerator/Freezers
Defrost
The defrosting process initiates automatically in response to a built-in timer.
All models are set for one defrost cycle every eight hours. The maximum length of the defrost
cycle is 20 minutes. The cycle terminates automatically if during defrost the evaporator coil
temperature exceeds 15°C.
Note
• The condensing unit is shipped with all service valves open and ready for operation. Do
not adjust the refrigerant valves or the temperature control. If adjustment of the
temperature control should become necessary, the adjustments may be made by qualified
personnel.
• All models have been provided with an electric condensate evaporator located on the back
of the cabinet. Periodic cleaning of the condensate pan will ensure proper operation. Refer
to image below for location of condensate pan.

Hinge and Latch Adjustment
Hinge Adjustment
1. Remove exterior hinge cover plate by opening the refrigerator door. Place a screwdriver
under interior portion of cover and gently pry cover outward. Pull straight out. Close
cover.
2. Loosen the three (3) screws "B" which hold adjusting plate "C" in position.
3. To tighten gasket seal, place hand against exterior of door near hinges; gently press in on
door so gasket sits firmly against cabinet face. Tighten screws "B".
4. When adjustment is complete, it hinges are adjusted so gasket seal is too tight, door will
tend to spring open. Door must be readjusted. To test gasket seal, insert a dollar bill (or
piece of paper of similar size) between the gasket and the cabinet opening. Close door; a
slight resistance to removal of the dollar bill (test strip) should be felt. Check the perimeter
of the door. If the latch is loose, see latch-adjusting information.
5. Replace cover plate "A."
Note To accomplish different offsets, shims are utilized. If replacing hinges, make sure to reuse any
shims furnished on the cabinet.

Latch and Strike Adjustment
1. Latch is fastened to door.
2. For up or down adjustment (proper latch engagement) loosen mounting screws "B".
3. Strike plate "C" remains in position.
4. Move strike "D" up or down as required and tighten screws "B" when adjustment is
satisfactory. No play will be present in the latch handle with the door closed.
5. For in and out adjustment (proper gasket seal) loosen screw "E". Adjust in or out as
required and tighten screw when adjustment is satisfactory.
6. The stainless steel hex head cap screw is 10/32" X 5/16" long. Use box wrench, open-end
wrench, or ratchet to tighten. Do not use a nut driver or pliers.
Note If replacing latch and strike assembly, make sure to reuse any shims furnished on the cabinet.

Maintenance
CAUTION Make sure power switch is off and unit is unplugged before doing any
maintenance or servicing.
WARNING Use nonflammable cleaner.
Failure to do so can result in death, explosion, or fire.
• Frequent cleaning of the interior and exterior with water and a good fungicidal detergent
that eliminates harmful bacteria, stains and other foreign matter will keep the unit fresh
and new looking.
• Shelves and/or drawers should be removed from the cabinet and thoroughly scrubbed. To
clean the drawers or shelves, use a solution of water and a mild detergent. Rinse the
drawers or shelves and wipe them dry with a soft cloth. For instructions on how to remove
the drawers/shelves refer to “Installation and Removal of Drawers”.
• The unit cooler fans do not require lubrication.
• The condensing unit does not require oil or other lubrication.
• Annual inspection of the mechanical refrigeration equipment by a qualified serviceman is
recommended. A qualified technician can make adjustments that will prevent future
breakdown.
Gasket Maintenance
Periodically check the gaskets around the door for punctures or tears. Door seal integrity is
critical for refrigerators and freezers. A gasket with a poor seal allows moist air to be drawn into
the cabinet, resulting in quicker frost buildup on the evaporator coil, longer running time,
poor temperature maintenance, and increased operation cost. Gasket leaks are indicated by
condensation that forms on the interior or exterior of the unit at the point of gasket failure.
Keep the door gaskets clean and debris free by cleaning with a solution of water and a mild
detergent. Gently wipe the gasket dry with a soft cloth.

Maintenance
Condenser Maintenance
16 Installation and Operation Thermo Scientific Jewett PRF17 Refrigerator/Freezers
Condenser Maintenance
CAUTION The finned condenser can become clogged with lint and dust. The
openings between fins should be kept clean. Condensers should be cleaned
at least every six months at a minimum. In heavy traffic areas, condensers
load with heavy dirt more quickly. Failure to keep the condenser clean can
result in equipment warm-up or erratic temperatures.
WARNING Be sure to disconnect the unit from main power before cleaning the
condenser.
CAUTION Never clean near condensers with your fingers. Some surfaces are sharp.
1. Disconnect the power.
2. Remove the screws shown in image below to access the condenser.
3. Use a vacuum cleaner with hose and brush attachments to clean the front face of the
finned surface shown in the image below.
4. Clean up any loose dust and replace the grill.
5. Reconnect the power.
Remove screws to remove grill Finned Surface
