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.
NEVER use an extension cord to power these units. 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

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.
3. Rotate your stock so that older stock does not accumulate. This is especially important for ice
cream. A "First-In, First-Out" rotation practice will keep the products in good sellable condition.
4. Do not place product in the case when it is soft or partially thawed. Also, 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 flourescent bulb/LED light bar, be sure that the electrical power to the lighting circuit is
turned off.
To comply with N.S.F. requirements, this cabinet must be sealed to the floor with NSF listed silicone
sealant. Before moving cabinet into place, route cabinet plumbing with P-trap to store drain line or install optional
condensate pan.

STORE CONDITIONS
®
The Master-Bilt
TEL/TEM 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.
LOCATION
The Master-Bilt® TEL/TEM 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.
Cabinet should not be built into an enclosed area. If this case is to be located against a wall there should be at least a 4”
space between the wall and the back of the case, with 4” open space at top and one or both ends. This space will allow
for the circulation of air behind the case which will prevent condensation on the exterior surfaces.
Make sure that the floor that will support this equipment is of adequate strength to prohibit sagging. After confirming the
dimensions of case with the blueprint measure off and mark on the floor the exact location of the cases for the entire
lineup. Snap chalk lines where the base skids of the case are to be located as shown in Figure 1.

LEVELING
It is very important that this equipment be perfectly level. This will allow for proper and complete drainage of the
evaporator coil and for proper case alignment. A perfectly level area is generally not available where the equipment is to
be installed. Mark the location of all case joining points front and back. Use a transit to locate the highest point on the
chalk lines. This point will be a reference point for determining shim-pack heights. Using the reference point, mark the
difference directly on the floor to each joining point front and back. Shim each joining point to equal the reference point
as required. Tape all shims in place. If the installation is an entire lineup install the case that will be positioned at the
highest point first. Check that the equipment in the lineup is level as the installation proceeds.
JOINING MULTIPLE SECTIONS
Remove the case from its shipping skid. Set the first case into its desired position with required shims in preparation for
joining it with its adjacent case.
Cases joined together require an application of butyl
caulking to provide an air-tight seal. Apply a generous bead
to all exposed foam edges at the end of the case. Inspect
the bead to make sure there are no gaps and that there is
sufficient material to provide a complete seal. The cases are
now ready to be joined together. Remove the second case
from its shipping skid and move it into position against the
end of the first case. Properly level the second case with the
appropriate shims.
Bolt the cases together through the seven holes that are
provided in the end frame as shown in Figure 2. Tighten the
bolts until all seams are fully closed. Do not over tighten.
Figure 2 – Case joining detail
Bolt the included sex bolts through the door frame to secure the door
frames together as shown in Figure 3. Make sure that the gasket
strips on each frame are intact and free of damage to ensure a proper
seal between the two frame sections. Repeat the above process for all
other cases in the lineup.
