4. Using the same procedure as above continue with the installation of the remaining corner panels.
5. Place a carpenter’s level against the face of the door frame to ensure correct vertical alignment and latch
the door frame to the roof panel while holding level in place.
6. Adjust the bottom wiper gasket of the door to the point that it sweeps the finished floor when the door is in
the fully closed position. (
Note: do not adjust the wiper gasket so far downs that it prevents the door
from closing property
.)
7. Before securing the panels to the floor, double check the door frame alignment by placing a carpenter’s
level vertically against each door frame leg.
8. Connect correctly fused 120Volts-service line to the J-box by the light fixture on the interior of the walk-in.
REFRIGERATION
NOTE: Wiring diagrams are located inside pre-wired electrical panel on the condensing unit.
Be sure electrical service is the same as the electrical characteristics on the compressor data plate. Connect
correctly fused service line to the service line J-box on the condensing unit.
After routing condensate line with standard trap from drain pan of evaporator coil, seal around drain line with
silicone or butyl caulking to prevent moist air entering box from outside.
Start compressor and allow running at least 24 hours before committing product into the walk-in. This 24
hours period should be a testing period to check temperature-holding range versus the temperature control
setting. On low temperature units, check the defrost control system to see that all ice is removed from the coil
during each defrost period. In addition all checks of door operation and all other component operation should
be checked.
