INTRODUCTION

Thank you for purchasing a Master-Bilt cabinet. This manual contains important instructions for installing, using and
servicing a Master-Bilt DD_LCG 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 DD_LCG 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. It is not uncommon in a newly
constructed store for the temperature and humidity to be above design conditions. These excessive conditions may
produce sweating in the case until the store is operational and the ambient environment is more desirable.

The Master-Bilt DD_LCG 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.

NOTICE

Read this manual before installing your cabinet. Keep the manual and refer to it before doing any service on
the equipment. Failure to do so could result in personal in jury or damage to the cabinet.

DANGER

Improper or faulty hook-up of electrical components of 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.

NOTICE

Installation and service of the refrigeration and electrical components of the cabinet must be performed by a
refrigeration mechanic and/or a licensed electrician

The portions of this manual covering refrigeration and electrical components contain technical instructions intended only
for persons qualified to perform refrigeration and electrical work.
