FREIGHT CLAIMS
IMPORTANT
FREIGHT CLAIMS INSPECTION:
You are responsible for all claims. It is vitally important that upon arrival, all
cartons and crates are inspected for visible damage. If at all possible, cartons and
crates should be opened immediately to check for concealed damage within. All
cartons and crates must be saved until the unit is completely removed from the carton
so concealed damage claims can be filed.
You, as the consignee, must file freight claims with the delivering truck line. If there
is any question whatsoever regarding the condition of the equipment, this question
should be noted on the bill of lading, which you sign as a delivery receipt.
All shortages must be noted on the bill of lading as the shipment is received. If a bill
of lading is signed as complete for the delivering truck driver, there is virtually no
way to secure a claim for shortages which are found later.

PRE-ASSEMBLY PROCEDURES
HANDLING AND SET-UP PRECAUTIONS
It is the responsibility of the installer to use safe unloading, handling, and construction
practices. If you have any questions about proper installation of the unit or accessories,
contact Master-Bilt.
Forklifts used to handle skids or panels must have forks
at least four feet long and set far enough apart to
adequately support panels or skids (see Figure Below).
Forklifts must have the capacity to support panels
weighing two pounds per square foot each.
STORAGE
When the unit must be stored at the job site prior to set-up, it is very important that it be
stored properly.
Whenever possible store the unit indoors. Panels stored indoors may be stored in their
original factory packaging. If it is necessary to store panels outdoors, stack them vertically
on skids, with spacers between the panels. This protects the panel edges and provides
proper ventilation. This method of stacking permits drain-off of moisture and guards
against rust stains.
Panels should be covered with a waterproof covering to protect them
from the weather. Master-Bilt recommends black polyethylene
sheeting, which keeps sunlight out and eliminates the "greenhouse"
condition, which occurs when clear plastic is used. In heavy traffic
areas, it is advisable to place protective rails around stacks of panels
to guard them from any possible damage.
NOTICE
Use material handling procedures appropriate to the job you are doing. Failure to use proper
loading or handling procedures or to follow manual instructions can cause bodily injury or
damage to your blast chiller.
NOTICE
The panels should be stored on a level area eliminating the risk of the panels falling and
injuring someone. The panels being stored should not be stacked over 2 skids high.

14
SITE CHECKLIST
-Inspect the area where your Master-Bilt® Blast Chiller will be installed.
1. Check to make sure the floor is level.
a. The entire floor under the Blast Chiller must be level, clean, and smooth.
2. Check the ceiling height above the Blast Chiller area:
a. Refer to the enclosed print specific to this project.
b. The top area of the Blast Chiller must be accessible for servicing.
c. Make sure proper clearance is allowed.
3. Ensure a drain is located near the Blast Chiller.
a. Make sure the drain is located relative to the enclosed Blast Chiller print.

STEP 2
INSTALL THE INSULATED WALL PANELS
-Refer to the enclosed panel print customized for your order.
-Locate and arrange panels according to the panel print.
-Hold the first panel in place.
1. Apply NSF approved clear silicone to the bottom of the panel.
2. Refer to the print to position the panel and cause it to seat within
the floor angle.
-Place the second panel in place.
1. Apply NSF approved clear silicone to the outside of the V joint
of the side panel and to the bottom.
2. Position the panel to cause it to seat within the floor angle.
-Lock the panels together using internal cam locks.
1. Locate cam lock wrench provided.
2. Insert wrench into the hex head socket in the
cam lock opening.
3. Rotate the cam lock clockwise until the lock
hooks with the adjoining panel.
4. Continue rotating until the lock pulls the
panel together snugly as shown above.
-Continue to erect the sides and back of the chiller box.
1. Ensure the panels are even at the top.
-Check all remaining cam locks.
1. Tighten or re-tighten as needed.
-Press the cam lock covers (plug covers) into the holes with your hands.
NOTICE
Occasionally, a cam fastener may not operate because the hex pin
socket is broken or damaged during assembly. If one cam on a panel
fails to fasten, the remaining cam fasteners provide adequate support
and alignment for assembly of the chiller.
NOTICE
The stainless-steel panels are covered with a protective sheet of
plastic. Remove the protective plastic covering from the wall panels
as each area is completed.
WARNING
Perform the following installation steps now. The area is not accessible after the evaporator and fan
assemblies are installed.
NOTICE
DO NOT INSTALL THE DOOR PANEL AT THIS POINT. The door panel must be installed after the
coil assembly. All other wall panels must be installed before the evaporator coil assembly.

17
STEP 3
INSTALL THE EVAPORATOR AND FAN ASSEMBLIES
-Refer to your project-specific print for proper positioning of the evaporator and fan
assemblies.
-Carefully unpack evaporator and fan assemblies.
1. Remove all protective plastic from the stainless parts.
2. Keep the assembly in a vertical orientation during positioning.
3. Move these assemblies with care.
-Refer to the drawing on the next page to assure the proper installation sequence is followed:
1. Slide the evaporator assembly in place.
2. Slide the fan assembly in place.
1. Use a level to plumb the evaporator and fan bank, shim as required for a tight level fit.
2. Mark location of evaporator assembly.
3. Slide the fan assembly temporarily into the opposite corner.
-Mark hole location for drain piping.
1. Locate drain piping on Blast Chiller Drawing and compare with drain at site location.
a. With evaporator assembly in its correct location, and the correct drain location
identified, measure for the drain line exit location and mark the side panel for a
1 ½” hole penetration.
b. The location of the drain will determine whether you need to run the piping
through the predrilled holes in the evaporator and fan assemblies.
c. Double check the hole location before drilling.
2. Drill a 1 ½” hole for drain line.
a. Evaporator assembly may have to be moved to allow access to drill.
3. Move evaporator and fan assemblies back into place and check hole location using pipe.
4. Move units back away from wall.
5. Apply NSF approved clear silicone to side and back flanges (full perimeter) of drip pan
(see diagrams below).
6. Push the assemblies back into place.
7. Use a level to plumb the evaporator and fan bank, shim as required for a tight, level fit.
-Remove the access covers on the lower front of the evaporator and fan banks.
NOTICE
You must slide the fan assembly in with a straight-on approach. The evaporator drain pan and
the fan assembly drain pan overlaps so they carry water to the drain opening together.
The evaporator and fan assemblies fit into position with a tight clearance.
WARNING
Beware of others on the opposite side of the panel when drilling through the wall.
CAUTION
Do not drill holes through the evaporator or fan assemblies; use the pre-drilled holes.

18
-Install the drain piping:
