INTRODUCTION Thank you for purchasing a Master-Bilt cabinet. This manual contains important instructions for installing, using, cleaning, and servicing a Master-Bilt BLG/BMG case. A parts list is included with this manual. Read all these documents carefully before installing or servicing your equipment. STORE CONDITIONS The Master-Bilt BLG/BMG cases are designed to operate in the controlled environment of an air-conditioned store.
NOTICE Read this manual before installing, cleaning, or replace any maintenaNce on your cabinet. Keep the manual and refer to it before doing any service on the equipment. Failure to do so could result in personal injury or damage to the cabinet. DANGER Improper or faulty hook-up of electrical components on the refrigeration units can result in severe injury or death. All electrical wiring hook-ups must be done in accordance with all applicable local, regional or national standards.
MECHANICAL Remove front grille and check refrigeration lines to see that they are free (not touching each other or compressor). Spin condenser fan blade to see that it is free. Check that all service valves are open. The compressor springs are secured for shipping by either tightening bolts or shipping strap. Remove the strap or loosen the hold-down bolts so that the compressor floats freely. If the compressor is hermetic, it is internally spring mounted and ready to run.
