Refrigeration Installation
Self-Contained Models
The self-contained models are shipped from the factory with a completely operational
refrigeration system and require no modifications or adjustments of the system upon
installation.
Remote Models (Obsolete as of 1/1/2012)
The remote models are designed to use 134A refrigerant and shipped from the factory with
the evaporator coil, expansion valve, refrigerant solenoid valve, and thermostat. The
thermostat senses interior case temperature and opens and closes the refrigerant solenoid
valve as needed to maintain proper case temperatures. The condensing unit is optionally
supplied from the factory for remote location installation.
A. Mount condensing unit indoors as close to the remote display as practical. The
refrigeration line should be as short as possible.
B. All refrigeration and/or electrical materials between the condensing unit and display
case are to be supplied by installing contractor.
C. Route properly sized and designed refrigeration lines from the condensing unit to the
cabinet. Horizontal suction lines should be pitched downward towards the condensing
unit and least ½” per 10’ run to aid the oil drainage. A “P” trap must be installed in the
suction line at the foot of every riser to insure oil return. Dry nitrogen should be used to
flow through tubing while brazing refrigeration lines.
D. Suction line must be insulated the entire length with Armaflex (or equivalent). Do not
run liquid line inside insulation with suction line.
E. The filter drier, sight glass, and low-pressure control are not furnished with remote
display case models. The recommended low pressure setting for R134A refrigerant is
32# cut in and 0# cut-out.
F. Leak check condensing unit, cabinet, and all connecting tubing. Cabinet and
condensing unit tubing should be checked to insure no leaks occurred during shipping
or from rough handling. Make certain all refrigeration valves are opened and evacuate
system to 500 microns. Charge the system with refrigerant type specified on the data
plates.

Pre-Service Checklist
You may avoid the cost and inconvenience of an unnecessary service call by first reviewing
this checklist of frequently encountered situations that can cause unsatisfactory case
performance.
1. Case Does Not Operate
a. Check for disconnected power supply.
b. Check for tripped breaker or blown fuse.
c. Check that the power switch and thermostat are not “off”
2. Lights Do Not Operate
a. Check that the light switch is on.
b. Be sure light is properly seated in the sockets.
c. Check that light cord(s) are tight in the sockets.
3. Case Temperature Too Warm
a. Check that the cold air inlet and outlet slots are not blocked.
b. Be sure front glass is closed tightly and back doors are closed.
c. Check for a blocked or dirty condenser coil.
d. Check 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
evaporator. If the evaporator coil is blocked due to excessive frost, turn the thermostat
knob to the “off” position for approximately one hour to defrost. Excessive frost will
build-up if the case is operated with the door open or ajar.
4. Glass Fogging
a. Check room ambient- Case is designed to operate in an environment not to exceed 75F
and 55% relative humidity.
b. Check case temperature- Case is designed to operate between 38F and 42F.
c. 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.
d. Check that the air flow is not being disturbed by a nearby fan or air duct.
e. Check that noting is placed on top of the glass case.

Series ’90 Refrigerated Bakery Page 20
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
hydrofluorocarbons (HFC’s) from being released into the atmosphere. The release of
HFC’s into the atmosphere is a potential source of global warming.
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 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.
SALE & DISPOSAL
Owner Responsibility
If you sell or give away your Federal Industries case you must make sure that all safety
labels and the Installation-Service Manual are included with it. If you need replacement
labels or manuals, Federal Industries will provide them free of charge. Contact the
customer service department at Federal Industries at [phone].
The customer service department at Federal Industries should be contacted at the time of
sale or disposal of your case so records may be kept of its new location.
If you sell or give away your Federal Industries case and you evacuate the refrigerant
charge before shipment, Federal Industries recommends that the charge be evacuated into a
recovery system to prevent the possibility of HFC’s from being released into the
atmosphere. The release of these HFC’s is a potential source of global warming.
