INTRODUCTION Thank you for purchasing a Master-Bilt cabinet. This manual contains important instructions for installing, using, and servicing a Master-Bilt BLG/TLG 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/TLG cases are designed to operate in the controlled environment of an air-conditioned store.
WARNING LABELS AND SAFETY INSTRUCTIONS This symbol is the safety-alert symbol. When you see this symbol on your cabinet or in this manual, be alert to the potential for personal injury or damage to your equipment. Be sure you understand all safety messages and always follow recommended precautions and safe operating practices. NOTICE TO EMPLOYERS You must make sure that everyone who installs, uses or services your cabinet is thoroughly familiar with all safety information and procedures.
PRE-INSTALLATION INSTRUCTIONS INSPECTION FOR SHIPPING DAMAGE You are responsible for filing all freight claims with the delivering truck line. Inspect all cartons and crates for damage as soon as they arrive. If damage is noted to shipping crates or cartons or if a shortage is found, note this on the bill of lading (all copies) prior to signing.
ELECTRICAL WARNING Before servicing electrical components in the case or the doors or door frames make sure all power to case is off. Always use a qualified technician. Check voltage and amps drawn on (Page 17-20) to determine proper line and fuse or circuit breaker size. Check power supply for low voltage. If voltage reads “230” with no load, and it drops below “207” when the compressor tries to start, it is an indication of too small supply wiring or too long to run.
DOORS The BLG/TLG cabinets have Anthony glass doors that are equipped with a patented TorqueMaster™ hinge system. The doors are easily adjusted using a flathead screwdriver (Fig.3). * The tension needs to be checked and set when first install. Leveling Adjustment Torque Adjustment Figure 3 To remove the door shipping clamps, remove the 4 shipping screws from the grill and remove the screws from the clamps (Fig.4), and replace grill.
