IMSS E3265 - 21 - 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 hydro-fluorocarbons (HFC’s) from being released into the atmosphere. The release of HFC’s into the atmosphere is a potential source of global warming. Note the condensing unit that was supplied with this case has a receiver tank large enough to hold all the charge you maybe able to pump down the system when service is required. 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.

IMSS E3265 - 24 - CONTROL OPERATION Electronic Control This unit is equipped with an Invensys – Ranco model E72R temperature control. The control parameters are set at the factory and cannot be manually changed in the field. Control parameter changes can only be made by downloading a new set of parameters via a program chip supplied by Federal Industries. The pre set control parameters are listed on the chart in the Settings Chart below. Operation The control uses two sensors, one located in the air stream and one located on the evaporator coil. The sensor located in the air stream is referred to as the temperature control sensor. The sensor located on the evaporator coil is referred to as the coil sensor. The temperature control sensor is located inside the center tower at the top. The sensor location is critical for proper operation on the unit. Do not move or relocate this sensor. The coil sensor is strapped to the evaporator coil. This sensor location is critical for proper operation of the unit. Do not move or relocate this sensor. The temperature control is set to cut in at 41 degrees F. The Temp control cuts out at 13 degrees F at the coldest setting’ COLD’ and 28 degrees F at the warmest setting, ‘1’ on the control dial. The temp control turns off the refrigeration system when the control is turned all the way counterclockwise. Defrost Cycle The Ranco control is programmed to initiate defrost via two different methods. There are 3 programmed defrost cycles in the case which will initiate a defrost cycle every 8 hours. The unit does not have a time clock so the defrost cycles cannot be set for any specific time of day. The unit also has an ‘On demand’ defrost feature that will initiate a defrost when the temperature differential between the evaporator temperature and the air temperature is more than 15 degrees for 5 minutes after 30 minutes into the refrigeration cycle. IMSS E3265 - 25 - Control Factory Settings The control parameters are set at the factory and cannot be manually changed in the field. Control parameter changes can only be made by downloading a new set of parameters via a program chip supplied by Federal Industries E3380 AS OF: 11/10/11

It is programmed to display the current discharge temperature from the control sensor located inside the center tower at the top. Maximum Run Timer, Before 5/23/12 Only The unit is equipped with a maximum run timer that is preset at the factory for 60 minutes on and 10 minutes off. If the temperature control does not reach cut out set point after running for one hour, the timer will turn the compressor off for 10 minutes. REFRIGERATION OPERATION Self Contained Models Refrigeration R404 Charge IMSS60 & IMSS84 6 Pounds Refrigeration R404 Charge IMSS120 8 Pounds The self-contained models are shipped from the factory with a completely operational 404A refrigeration system and require no modifications or adjustments upon installation. Case must be installed as per the installation section of this manual to provide proper condensing air cooling. Self Contained Refrigeration Operation The unit temperature is controlled by the Electronic control and timers outlined in the control section of this manual. Note: The condenser fan runs continuously. Remote Models Use pressure gauges to set pressure control. Refrigeration R404 Charge CHARGED IN FIELD Remote Low Press. Switch Cut In 50 psi Remote Low Press. Switch Cut Out 15 psi Adjustable Head Master 200 psi Remote High Press. Switch Cut Out 400 psi The remote models are designed to use 404A refrigerant and shipped from the factory with the evaporator coil, expansion valve, sight glass and refrigerant solenoid valve. Drier filter most be installed in field for proper operation. Electronic control runs identical to the Self Contained models except the electronic control opens and closes a refrigeration solenoid valve located on the suction line instead of turning on and off a compressor. The solenoid valve closes and shuts off the refrigeration flow to the unit and initiates a pump down cycle. This will allow the remote low pressure switch to open and shut off remote compressor. The condensing unit and pressure controls are optionally supplied from the factory for remote location installation. The condensing unit must be mounted and wired by the installer. The high IMSS E3265 - 27 - low pressure switch must be wired in series with the compressor power supply as shown in diagram below. 1. Mount condensing unit indoors as close to the remote display case as practical. The refrigeration line should be as short as possible and must not exceed 30 feet. 2. All refrigeration and/or electrical materials between the condensing unit and display case are to be supplied by installing contractor. 3. 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 at 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 must be used to flow through tubing while brazing refrigeration lines. 4. Suction line must be insulated the entire length with Armaflex (or equivalent). Do not run liquid line inside insulation with suction line. 5. The remote high/low-pressure control must be mounted, wired and set pressures by the installer. 6. 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. DISPLAY CASE AIR TEMP. CONTROL PROBE
