INTRODUCTION
Thank you for purchasing a Master-Bilt cabinet. This manual contains important instructions for installing, using and
servicing a Master-Bilt
QMVM
series open air case. Read all these documents carefully before installing or servicing
your equipment. This manual should be left in the care of the store owner or manager.
STORE CONDITIONS / LOCATION
The Master-Bilt
QMVM
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
QMVM
should not be positioned where it is directly exposed to rays of the sun or near a direct source
of radiant heat or air flow. No HVAC return or supply air ducts may be located near case openings. This will adversely
affect the case air flow and will result in poor performance. Do not open windows or doors that will affect the case air
flow. The maximum air velocity near the case air return is 50 FPM. If this case is to be located against a wall there
should be at least a 6” space between the wall and the back of the case. The cabinet also requires a clearance of 10”
at the top. This space will allow for the circulation of air behind the case.
These cases should always be loaded properly. This unit will operate differently when loaded or unloaded. Consult
the section of this manual that specifies loading procedures on page 6.
A P-trap is included with each case. It is important that each case has a P-trap installed. Consult the section of this
manual for installing and piping the drain.
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 portion of this manual covering refrigeration and electrical components contain technical instructions intended
only for persons qualified to perform refrigeration and electrical work.
This manual cannot cover every installation, use or service situation. If you need additional information, call or write
