1. Insert 17 mm socket and rotate 1/4 turn clockwise as
shown in Figure 12. If the handle is on the left side of the
door, rotate 1/4 turn counterclockwise.
2. Rotate the door handle 1/4 turn clockwise and then 1/4
turn counterclockwise to release any internal pressure
or vacuum and open the door. If the handle is on the
left side of the door, rotate the door handle 1/4 turn
counterclockwise and then 1/4 turn clockwise.
3. To prevent air leakage, tighten the door panels by
adjusting the jam nuts.

Injected-Foam Insulated Panels
Flame and smoke can cause equipment damage, severe
personal injury, or death. Before operating unit, seal all
piping and wiring holes on both inner and outer panels with
an industrial grade silicone sealant or duct seal compound.
Panel
damage can occur.
Vision air handlers are furnished with double-wall, injected
foam insulated panels. Foam panels are stronger, more rigid,
and lighter than panels with berglass insulation. The insulation
R-value is improved to 13. However, foam insulation can burn
when exposed to ame or other ignition sources and release
toxic fumes. Use caution when cutting and sealing all eld-cut
openings in these panels.
Panel Cutting Procedure
1. Determine the number and location of holes required for
electrical conduit, piping, and control wiring as follows:
— Check that adequate space is available inside the unit
for conduit or pipe routing.
— Do not locate holes in a panel that provides access to
key maintenance components such as lters and fan
assemblies.
— Do not locate where the conduit or piping blocks
airow or obstructs hinged access doors.
2. Once a proper location is determined, drill a small pilot
hole completely through the panel. Use a sharp hole saw
or a saber saw and cut from each side of the panel.
3. Seal the double-wall panel on each side with an
industrial/ commercial grade silicone sealant or duct
seal compound. It is extremely important to seal each
panel hole or penetration securely so that it is airtight,
watertight, and so that there is NO EXPOSED FOAM
INSULATION. .
