Continental Scientific Refrigerators and Freezers, Instruction Manual

the condensing unit is 208-230 volts in which the wiring includes a neutral and a 
mechanical ground. This wiring should be connected to the appropriate power 
source by a qualified electrician and must conform to all local electrical codes. 
 

SPECIAL VOLTAGE CONNECTIONS 

When models are ordered from the factory with special, optional voltages, 
connections should be made as required on the electrical wiring diagram provided 
on the upper cabinet end panel next to the electrical console box. 
 

START-UP CHECKLIST 

After your model has been installed, leveled, cleaned, and electrically connected in 
accordance with this manual, please take the time before start-up to observe the 
following precautions to assure troublefree operation: 

1.  Check that all exposed refrigeration lines are free of severe dents or kinks. 
2.  Check the condenser fan and evaporator fans for freedom to rotate without 

any obstructions 

3.  Make sure that the cabinet is properly leveled (see "leveling" under 

installation and location section). 

 
The system should run smoothly and quietly in accordance with generally 
accepted commercial standards. If any unusual noises are heard, turn the unit off 
immediately and check for any obstructions of the condenser or evaporator fans. 
Fan motors, fan blades, or fan housings can be jarred out of position through 
rough handling in transit or during installation. 

 
Important Note:

 All freezer models have an energy-saving fan delay control to 

prevent the interior fans from operating until the evaporator becomes chilled. 
Therefore, on initial start-up, the fans will not turn immediately. 

This is a normal 

mode of operation.

 Allow sufficient time for the evaporator coil to reach its 

operating temperature (approximately 20 minutes). 

 
Caution:

 If unit is unplugged or disconnected for any reason, allow several 

minutes (5-6 minutes) before turning the unit back on to allow the system 
pressures to equalize. Disregarding this procedure could cause an overload and 
prevent the unit from operating. 
 

REMOTE APPLICATIONS 

All models are available for purchase as remote models in which case the 
condensing unit is purchased separately and installed at the time of installation. All 
remote models are equipped with an expansion valve located within the evaporator 
coil housing, and both liquid and suction lines stubbed and extending out from the 
cabinet case top behind the front grill. Installation of the refrigeration accessories,
