INTRODUCTION Thank you for purchasing a Master-Bilt cabinet. This manual contains important instructions for installing, using and servicing a Master-Bilt GT case. A parts list is included in with this manual. Read all these documents carefully before installing or servicing your equipment. STORE CONDITIONS The Master-Bilt GT cases are designed to operate in the controlled environment of an air-conditioned store. The store temperature should be at or below 75°F and a relative humidity of 55% or less.
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.
INSTALLATION INSTRUCTIONS GENERAL INSTRUCTIONS 1. Be sure the equipment is properly installed by competent service people. 2. Keep the equipment clean and sanitary so it will meet your local sanitation codes. 3. Rotate your stock so that older stock does not accumulate. This is especially important for ice cream. A "First-In, First-Out" rotation practice will keep the products in good sellable condition. 4. Do not place product in the case when it is soft or partially thawed.
To comply with Sanitation requirements, the cabinet must be mounted on legs (6” high minumum) or the base must be sealed to the floor using N.S.F. listed RTV silicone sealant. Minimum clearance as follows: 0” rear and side, top and front are open required for compliance. GRILLE REMOVAL AND COMPRESSOR CHECK Remove 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.
30 Hour Dial The unit defrost is controlled by a timer in the control box. After removing the condenser grille, the control box will slide out until the defrost timer is visible. The factory set defrost is two times in 24 hours with a maximum timed interval of 30 minutes. The unit contains a defrost termination sensor so in actual use the defrost time will be less than 30 minutes in most cases.
CLEANING WARNING: DO NOT REMOVE FROST WITH A KNIFE, PICK, OR SHARP OBJECTS. DO NOT USE ABRASIVE CLEANERS OR CAUSTIC CLEANERS OR SCOURING PADS Every 30 to 60 days (depending on frost accumulation), the cabinet should be emptied, warmed up, and wiped down using a solution of 1 teaspoon of baking soda with 1 quart of water. This solution will help eliminate odors. Do not use strong soaps or detergents as they leave odors that can contaminate your product.
Glass Lid and Top Deck Removal Top Deck Price Tag To remove the glass lid, start in the closed position and lift up on the front extrusion. Pull the glass lid towards you to remove it from the track. Reverse procedure to reinstall. To remove the top deck, slide (remove) insert strip from price tag moulding. Remove screws which are now exposed to remove the price tag moulding. Remove screws on sides of the cabinet which also attach the top deck. Reverse procedure to reinstall.
