INTRODUCTION
Thank you for purchasing a Master-Bilt cabinet. This manual contains important instructions for installing, using and
servicing a Master-Bilt MPM/QMPM 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 MPM/QMPM 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 MPM/QMPM 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. Check drain tubing to
insure that it is traped and routed into the condensate pan.
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

INSPECTION FOR SHIPPING DAMAGE
You are responsible for filing all freight claims with the delivering truck line. Inspect all cartons and crates for
damage as soon as they arrive. If damage is noted to shipping crates or cartons or if a shortage is found, note this
on the bill of lading (all copies) prior to signing.
If damage is discovered when the cabinet is uncrated, immediately call the delivering truck line and follow up the call
with a written report indicating concealed damage to your shipment. Ask for an immediate inspection of your
concealed damage item. Crating material must be retained to show the inspector from the truck line.
