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 contains 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 us:

PRE-INSTALLATION INSTRUCTIONS

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.

INSTALLATION INSTRUCTIONS

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. Wipe up all spills,clean with water and a mild detergent, then rinse with clean water. A reservoir is provided to contain interior spills.

Peridocially inspect reservoir and clean as needed.

3. Rotate your stock so that older stock does not accumulate. A "First-In, First-Out" rotation practice will keep the products in good salable condition.

4. 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.

INSTALLATION INSTRUCTIONS

To comply with N.S.F. requirements, this cabinet must be mounted on casters or the base must be sealed to the floor with NSF listed silicone sealant. Optional casters screw into the holes from which the shipping bolts were removed. Minimum clearance as follows: 10” air space at top, 6” at the rear, and 0” air space at each side required for compliance. This space will allow for the circulation of air behind the case which will prevent condensation on the exterior surfaces.

Before moving cabinet into place, route cabinet plumbing with P-trap to store drain line or install optional condensate pan.

THERMOMETER INSTALLATION

ANSI/NSF 7, requires that the provided thermometer be installed in the warmest part of the case. Testing has shown that the sides of the refrigerated space near the load line is the warmest, place see figure 1.1 below.

Remove the tape backing and press the thermometer in place.

CONDENSATE EVAPORATOR

The MPM/QMPM is designed to operate in an environment of 75 ° ambient and 55% relative humidity. When the conditions are applicable for condensation such as high temperature and high humidity, a large capacity condensate evaporator has been installed in the MPM/QMPM to ensure proper evaporation.

POWER TOGGLE SWITCH

The toggle switch turns the power ON or OFF and is accessible through a slot at the back of the MPM/QMPM-

36 and MPM/QMPM-48 cabinet.

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 made should determine if the cabinet is malfunctioning or if there is a drain pipe leaking.

ELECTRICAL

WARNING

Before servicing electrical components in the case make sure all power to case is off. Always use a qualified technician.

STARTING PROCEDURE

I.

Check condensing unit for vibrating or rubbing tubing. Dampen and clamp as required.

All valves should be completeley open counter-clockwise.

Check packing nuts on all service valves.

Replace all service valve caps and latch unit covers

LOADING

Do not place product in the case until 6 hours after it is started. Stock cases as quickly as possible, exposing only small quantities to store temperatures for short periods of time. It is important to keep stock rotated properly so that older stock does not accumulate. A “First-In, First-Out” rotation practice will keep the products in good salable condition. Avoid loading the case so that product sticks out beyond the shelves or blocking the return air grille at the bottom of the case. This will interfere with the air flow of the case and will result in diminished performance.

CLEANING

To avoid electrical shock, turn the power off before cleaning.

The QMVM series cabinets are designed so that spills will accumulate in a drain pan. The drain pan is located underneath the return air grill. Be sure to clean all areas with a mild detergent and water periodically.
