Installation - Refrigeration Module - Trane Thermo King V-520 RT SPECTRUM 50 Installation Manual

Support Plates
Thermo King recommends securely installing steel support plates (installer
supplied) to the vehicle's inner roof support structure prior to insulating
and finishing the interior ceiling. These support plates should have correct
size mounting studs or thread inserts installed to safely secure the V-520
Refrigeration, Condenser and Power Pack Modules to the vehicle's roof.
The support plates should be located to correctly position the refrigeration
module and condenser modules in relationship to the interior bulkhead and
evaporator. See "Dimensions and Weight - Model 50 SPECTRUM" on
page 12.
Preferred Installation Method
(with pre-installed support plates and pre-cut access hole)
1. Remove the plastic cover from the refrigeration module and trim the
foam gasket away from the two drain holes located in the corners.
2. Install rubber gasket (supplied) around access hole opening.
3. Apply neutral/alcohol cure silicone sealant around all mounting bolts
or inserts.
4. Use an appropriate 2-point lifting device with locking hooks attached
to the modules's two lifting brackets and raise into position on vehicle's
roof.
5. Secure refrigeration module to the roof using the supplied 1/4" lag
bolts and washers and hand tighten securely. NOTE: Multiple
mounting holes are provided every two inches along the sides of the
refrigeration module for mounting options. Choose four mounting
holes, ideally one in each corner to secure the refrigeration module.

Alternative Installation Method
(without pre-installed support plates and pre-cut access hole)
1. Remove plastic cover from refrigeration module and trim foam gasket
away from the two drain holes located in the corners.
2. Locate and mark the center line (C/L) of vehicle's roof.
3. Determine location of interior bulkhead in relationship to vehicle's
roof. Mark location of bulkhead on vehicle's roof.
4. Use "Dimensions - Refrigeration Module Mounting Holes" on
page 15) to mark location on roof of refrigeration module's 133.35 mm
(5.25 in.) access hole and mounting holes. NOTE: Multiple mounting
holes are provided every two inches along the sides of the
refrigeration module for mounting options. Choose four mounting
holes, ideally one in each corner to secure the refrigeration module.
• Confirm large access hole is positioned behind bulkhead and inside
of cargo compartment. NOTE: This is necessary so the
refrigeration hoses and electrical harness will be located on the
inside of cargo compartment, not in the passenger compartment.
• Choose mounting holes spaced farthest apart whenever possible.
• Confirm there is no internal structural roof supports where access
holes will be drilled.
5. Mark and drill four 5 mm (0.472 in.) mounting holes only into the
internal ceiling supports in the roof.
6. Mark and cutout 133.35 mm (5.25 in. dia.) access opening for
refrigeration tubing/electrical harnesses. NOTE: This hole will be
drilled completely through the roof and into interior compartment.
7. Install rubber gasket (supplied) around access hole opening.
8. Apply neutral/alcohol cure silicone sealant around all mounting bolts
or inserts.
9. Use an appropriate 2-point lifting device with locking hooks attached
to the modules two lifting brackets and raise into position on vehicle's
roof.
