INTRODUCTION
Thank you for purchasing a Master-Bilt cabinet. This manual contains important instructions for installing,
using and servicing a Master-Bilt
SMB/WMB
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
SMB/WMB
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
SMB/WMB
should not be positioned where it is directly exposed to rays of sun or near a direct
source of radiant heat or air flow. 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” 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 and allow the refrigeration system to discharge air properly.
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 injury 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.
