Nor-Lake Stability Chambers - Manual (Page 5)

- 5 -
The cabinets utilize electrically operated heaters to warm the cabinets in the heating mode. The
heating elements are located in the interior cowl. The programmable control is factory set with a
cutout temperature to prevent the cabinet from exceeding its design limits.
Note
: The cabinets are equipped with two switches located on the façade. One is the main power
ON/OFF switch for the unit. The other is a three-position switch for the battery-powered alarm. The
alarm switch is placed in the middle, or OFF position, for shipment. When the Stability Chamber is
put into operation, the top of the switch should be pushed in to the ON position. With the switch in
the ON position, the battery will sound the alarm if the main power to the cabinet is interrupted.
The switch flipped to the bottom position is used to test the battery. This test must be done with
power uninterrupted to the cabinet. The alarm will sound if the battery is good. This test should be
done periodically. The battery is located on the backside of the control box that is on top of the unit
behind the façade.
MAINTENANCE
PERIODIC CLEANING
Disconnect power source, including optional duplex power cord if equipped, before servicing or
cleaning.
Beginning with the initial installation, the interior surfaces of the cabinet should be periodically
wiped down with a solution of warm water and baking soda. This solution will remove any odors
from spillage that has occurred. The exterior of the cabinet should also be cleaned frequently with
a commercial grade of glass cleaner. Caution: Do not use an abrasive or alkaline solution.
Monthly cleaning of the condenser will aid the heat transfer characteristics of the refrigeration
system and increase its efficiency. Dust, dirt, and lint may accumulate on the fins of the
condensing unit. This obstruction may affect the flow of air through the condenser, thereby
lowering the efficiency of the system. A wire brush or a brush with stiff bristles can be used to
loosen these particles that are attached to the fins so that they may be removed with a vacuum
cleaner. Important: Failure to keep the condenser coil clean and clear of obstructions could
result in temperature loss and damage to the compressor.
All moving parts have been
permanently lubricated and will generally require no maintenance.
