Installation - Power Pack 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

standby compressor prior to installing the Power Pack Module onto the
roof. See "Installation - Refrigeration Tubes to Compressor" on page 38.
