1. Connect the power cord to the vaporizer

and place it in the vaporizer bracket.

2. Attach the vaporizer bracket to the back

of the unit using the four screws as

LOCATION


The refrigeration system located at the top of
the cabinet requires free air access for
proper operation. Allow a minimum four-inch
clearance on the top, rear, and sides of the
cabinet. The cabinet should also be leveled
when it is placed in its permanent location.

ELECTRICAL


Check the proposed outlet to be used to insure that the voltage, phase, and current carrying
capacity of the circuit from the electrical panel correspond to the requirements of the cabinet. Never
use an extension cord to wire any unit. On permanently connected units, those not furnished with a
plug-in service cord, all inter-wiring between the electrical panel and the unit must be done in
accordance with the National Electric Code and all state and local codes. Refer to the serial tag for
all pertinent electrical information.
Observe all Warning Labels. Disconnect power supply to eliminate injury from electrical
shock or moving parts when servicing equipment.

GENERAL OPERATION

FORCED AIR UNITS


The General Laboratory forced air cabinets employ a unit cooler evaporator located inside the
cabinet as the heat-removing source. Through the refrigeration process, heat is captured in the
evaporator, transferred to the condensing unit on top of the cabinet, and expelled to the surrounding
outside air. It is extremely important to allow a four-inch clearance on the top, rear, and sides of the
unit for the refrigeration process to function properly.


Cold control adjustment

To increase or decrease the internal cabinet temperature, rotate the cold control, located on the unit
cooler, to the desired temperature.
