2. Partition Wall Caulking
As an added precaution against vapor leaks, Bally recommends
that all joints from partition wall panels to breaker panels
(vertical, ceiling, floor) be caulked during assembly. See Figure 15.
3. Air gap/circulation recommendation.
Bally recommends a 2” gap between Walk-In vertical panels and
existing building walls for proper air circulation. It is also
recommended that air exchange/circulation be provide for Walk-
In s that are within an enclosed area.
4. Making holes for Refrigeration Tubing and Electrical Lines
If penetrations in panels are needed, avoid the areas that are
shown. Penetrations should be made as needed by competent
installer or mechanical service. If shaded areas are avoided,
urethane insulation can be easily removed from opening. After
equipment installation, fill in hole with permagum caulk. See
Figure 16.
A. When a remote refrigeration system is used, it will be necessary at
the job site to make holes for refrigeration and electrical lines.
B. After installation, use permagum to caulk around the electrical
and refrigeration lines. Caulk both the interior and exterior gaps.
C. Condensation in electrical junction boxes is caused by warm
vapor passing from the exterior to the interior of the Walk-In
through electrical conduit lines. This problem can be eliminated
by installing a seal-off fitting in the conduit line where it passes
through the wall. Install the fitting as shown in Figure 17 and fill it
with sealant.
5. Making electrical connections to Entrance Doors and
Installing Vapor-proof Lights
A. Electrical connections to the Walk-In doors are made at the top
interior of each door panel. Remove the socket plate to expose
the wire connections in the junction box.
B. Remove the short wire “pigtails” and connect the service at the
wire nuts, through the hole provided in the junction box. Refer
to serial tag for proper electrical characteristics. Insure that the
electrical service is properly grounded. See Figure 18. Remount
the vapor-proof light assembly after all connections have been
made.
Do not turn on power to door section until after the
refrigeration system has been started.
