    LEVELING The refrigerator must be level to insure proper operation of the refrigeration system and to insure proper drainage of defrost water. Use the leveling shims provided to level the case with the aid of a carpenter’s level. Leveling must be performed from front-to-back and from side-to- side.

    Refrigerant lines should be sized as shown on the refrigeration legend prepared for the store and as (furnished by the owner). If a legend has not been furnished, refer to Section 12 of the Hussmann Application Engineering Manual for guidance. OIL TRAPS P-traps (oil traps) must be installed at the base of all suction line vertical risers.

    PIPING INSULATION For refrigerators with other than KOOLGAS defrost, the suction and liquid lines should be clamped and/or taped together and insulated for a minimum of 30 feet from the refrigerator. Refrigerators with KOOLGAS defrost should not have their liquid and suction lines in contact with each other but are to be separately insulated for a minimum of 30 feet from the refrigerator.
  • Page 11 A pump down system is recommended for outdoor condensing units. DEFROST: ISFGG / RGG, models have electrical defrost and are time initiated with pressure termination. For Koolgas application, a Klixon sensor is mounted on the coil to provide a temperature termination control signal.

  • Page 13 Electric defrost is time initiated and temperature terminated. Termination is initiated by a “close-on-rise” Klixon sensor mounted on an evaporator tube. “Off-time” defrost is time initiated and time terminated. REFRIGERATION CONTROLS Low Temp (Frozen Food) ISFGG-R Medium Temp (Dairy, Deli) ISMGG- Medium Temp (Dairy, Deli) Discharge air temperature is to be measured by attaching a service thermometer to the discharge honeycomb at the centre of the case.
  • Page 14 Page 14 REMOTE CONTROL KIT (Optional) The control settings listed in the preceding tables are those that will provide proper case performance. If these spot display refrigerators are to be multiplexed with different types of refrigerator models, we suggest that each spot display refrigerator be equipped with a “REMOTE CONTROL KIT”. The remote control kit will insure better control of refrigeration temperature and provide additional defrost controls that maybe needed since most other refrigerators do not have similar defrost frequencies and terminations (fail safeguards) with these spot display refrigerators.

  • Page 27: Service Tips

    SERVICE TIPS ALWAYS DISCONNECT THE ELECTRICAL POWER AT THE MAIN DISCONNECT AND OBSERVE ALL ELECTRICAL LOCKOUT PROCEDURES, WHEN SERVICING OR REPLACING ANY ELECTRICAL COMPONENT OF THIS REFRIGERATOR. THIS INCLUDES, BUT IS NOT LIMITED TO SUCH ITEMS AS FANS AND THERMOSTATS. FAN BLADE REPLACEMENT The evaporator fan is located at the centre of the case directly beneath the display pan.
  • Page 28 Page 28 ANTI-SWEAT HEATERS The anti-sweat heaters are located along the lower glass perimeter and inside the nose discharge panel. Servicing the anti-sweat heaters requires removal of the corner caps, then the glass or nose discharge panel. To remove corner caps simply hold part and pull upwards. Corner caps naturally fit tight to prevent undesirable removal.
