Check that the power switch and thermostat are not “off”.
Pre-Service Checklist
Lights Do Not Operate
Check that the light switch is on.
Be sure light is properly seated in the sockets.
Check that light cords are tight in the sockets.
Case Temperature Too Warm
Check that the cold air inlet and outlet slots are not blocked.
Be sure the front glass is closed tightly and back doors are closed.
Check for cold air flow. Lack of adequate cold air flow could be a defective evaporator fan
or blocked evaporator coil. Check that paper or foreign material is not blocking the
evaporator. If the evaporator coil is blocked due to excessive frost, turn the thermostat
knob to the “off” position for approximately one hour with the power switch in the “on”
position to defrost. Excessive frost will build up if the case is operated with the doors open.
Glass Fogging
Check ambient- case is designed to operate in an environment of 75F and 55% relative
humidity.
Check case temperature- case is designed to operate between 38F and 42F.
Check that nothing is blocking the warm air vents in the glass handle.
Check that warm air is being blown evenly across the front glass surface. If the air is not
blowing or is not blown evenly, service is required.
Check that the air flow is not being disturbed by a nearby fan or air duct.

Series ’90 Cold Deli Display Page 17
Check that nothing is placed on top of the case glass.
Special Service Situations
There are rare occasions when the refrigerant charge must be evacuated from a case in order to
perform service work. In those situations, Federal Industries recommends that the refrigerant
charge be evacuated into a recovery system to prevent the possibility of hydrocholrflurocarbons
(HCFC’s) from being released into the atmosphere. The release of HCFC’s into the atmosphere is
a potential source of ozone depletion.
If moisture or liquid is observed around or under a Federal Industries case, an immediate
investigation should be made by qualified personnel to determine the source of the moisture or
liquid. The investigation made should determine if the case is malfunctioning or if there is a simple
housekeeping problem.
Moisture or liquid around or under a case is a potential slip/fall hazard for persons walking by or
working in the general area of the case. Any case malfunction or housekeeping problem that
creates a slip/fall hazard around or under a case should be corrected immediately.
