GP, Explosion-Proof and FMS Lab Refrigerators and Freezers
Electrical Connection
Determine the total amount of current presently being used by
other apparatus connected to the circuit that will be used by
this refrigerator. It is critical that this added current demand
and other equipment on this circuit not exceed the rating of
the fuse or circuit breaker in use.
The frequency and nominal voltage requirements for the unit
are specified on the data plate, which is located on the door’s
exterior. Only supply this unit with an electrical source that
meets these requirements. Low line voltage is often the cause
of service complaints. With the unit running, check that the
line voltage is within ±10% of that specified on the data plate.
CAUTION:
Be sure the voltage supplied to the
refrigerator/freezer is equal to that specified on
the data plate.
WARNING:
For personal safety, this unit must
be properly grounded before use.
Door Seal
To check the door seal, complete the steps:
1. Open the door.
2. Insert a strip of paper (a couple of inches wide) between
the door gasket and the cabinet flange and close the
door.
3. Slowly pull the paper strip from the outside. You should
feel some resistance.
4. Repeat this test at 4 inch intervals around the door. If the
door does not seal properly, replace the gasket.
Safety Tips
•
After a unit is in operation, do not touch the
cold surfaces, particularly when hands are
damp. Skin may adhere to the cold surfaces.
We recommend handling samples by
wearing gloves to avoid frost bite.
•
Never disconnect your unit by pulling the
power cord. Always grip the plug securely
and pull straight out from the outlet.
•
Do not use a power cord that shows cracks
or abrasions. Have a qualified electrician
repair or replace damaged cords
immediately.
