Doors/Panels
Removable access panels are provided
directly across from most access doors. If
regular access is required from the panel
side of the unit, the doors and panels can be
swapped or additional doors can be ordered
from
the factory. Contact sales
representative to order additional parts.
Note: For safety, inside-opening doors are
used in positive pressure sections and
outside-opening doors are used in negative
pressure sections. The opening direction of
doors cannot be changed.
To remove an access panel, remove bolts
from the perimeter. When replacing a panel,
make sure that the neoprene gasket on the
panel is not damaged. Do not over-tighten
the bolts as this could cause the rivet-nuts to
come loose.
Figure 36 - Access Door/Panel Removal
Outside Opening Door and Panel
To switch the door and access panel
locations remove panel and remove door by
removing the screws connecting the hinge to
the unit. For inside opening doors, the gap
covers around the door opening should also
be removed.
Shut off power to unit and wait for
fans to stop turning before removing
an access panel. To make sure the
unit is not pressurized, open door
opposite the access panel. Serious
injury can result from removing a
panel under positive pressure.
