Nor-Lake Lighted Chambers - Manual (Page 7)

- 7 -
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.
CLEANING THE HUMIDIFIER
Before Cleaning
:
1. Disconnect the electrical plug from power source. Turn off water supply. (See Figure D)
2. Unfasten the Dome Strap and remove the Dome from the humidifier assembly by lifting it from
the chromed Motor Pan (Figure B).
