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. The
store temperature should be at or below 75°F and a relative humidity of 55% or less. At higher temperature or humidity
conditions, the performance of these cases may be affected and the capacity diminished.

The Master-Bilt BLG/BMG should not be positioned where it is directly exposed to rays of sun or near a direct source of
radiant heat or airflow. This will adversely affect the case and will result in poor performance.

If this case is to be located against a wall, there should be at least 4 to 6” space between the wall and the back of the
case. This space will allow for the circulation of air behind the case, which will prevent condensation on the exterior
surfaces.

WARNING LABELS AND SAFETY INSTRUCTIONS

manual, be alert to the potential for personal injury or damage to your equipment. Be sure you

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. Clean the cabinet with a mild

detergent and water, then rinse.

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 salable condition.

4. Do not place product in the case when it is soft or partially thawed. Also, product should not be put in the case

for at least 6 hours after it is started.

5. Stock cases as quickly as possible, exposing only small quantities to store temperatures for short periods of

time.

6. When replacing burned out fluorescent tubes, be sure that the electrical power to the lighting circuit is turned off.

NOTICE TO STORE OWNERS / MANAGERS

Moisture or liquid around or under the cabinet is a potential slip/fall hazard for persons walking by or working
in the general area of the cabinet. Any cabinet malfunction or housekeeping problem that creates a slip/fall
hazard around or under the cabinet should be corrected immediately.

If moisture or liquid is observed around or under a Master-Bilt cabinet, an immediate investigation should be
made by qualified personnel to determine the source of the moisture or liquid. The investigation should
determine if the cabinet is malfunctioning or if there is a drain pipe leaking.
