Nor-Lake Stability Chambers - Manual (Page 4)

An 18” length of 1/2" I.D. drain hose is shipped inside cabinet. Attach hose to drain stub under
cabinet with supplied clamp and run to an atmospheric floor drain. May substitute longer drain
hose as needed. Humidifier units will require a drain for overflow.
ELECTRICAL
For electrical requirements see data information and wiring unit diagram located in parts bag,
inside of the cabinet.
Check the proposed external power outlet/supply to be used to ensure 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. Refer to the serial tag (nameplate
data) for all pertinent electrical information.
Observe all Warning Labels. Disconnect power supply(s) to eliminate injury from electrical
shock or moving parts when servicing equipment.

GLYCERIN WELL ASSEMBLY
Important: For accurate product temperature reading, the
product-sensing bulb must be immersed in glycerin
solution contained in the provided well.
One glycerin well is furnished with each model. The
purpose of the glycerin is to simulate the product stored in
the Stability Chamber. The glycerin temperature reflects
the product's temperature during normal operation.
Figure 1
After the unit is put into operation. Check to make sure that
the temperature indicating or alarm sensing bulb is
positioned inside the glycerin well. As far as possible
without touching the well itself.
OPERATION
The Stability Chambers are designed for an operating range of 4°C to 70°C Temperature only, 5°C
to 60°C Temperature with Humidity.
These units employ a programmable controller to control the temperature, defrost and humidity
settings. The controller, which is located on the facade of the unit, is factory set. Please see the
separate instructions, part number 113635, on the operation of the controller used in the Stability
Chambers.
The cabinets use an evaporator coil, located on top of 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.
