Handling and Storage
Fans should be lifted by the panel mounting flanges. Never by the propeller, motor, motor bracket, fan inlet, shutter
frame, or any other part not designed for lifting.
If the fan is stored for any length of time prior to installation, the fan and accessories should be stored in a dry, clean
location. If outdoor storage is necessary, protection should be provided. The fan should be covered to prevent the
accumulation of dirt and moisture. Cover motors with waterproof material.
Check shutters for free operation and lubricate moving parts prior to storage. Inspect the stored unit periodically.
Rotate the
propeller by hand every two weeks.
Installation
Cut out wall opening of sufficient size so that, when framed in, the finished opening will accept the fan and wall box
assembly, (refer to MK Plastics submittal for specific outside dimensions of the wall box). It is preferable to frame in
the opening with 2 x 6 material, or other similar suitable material or metal channels adequate to support the fan as
shown in Figure 2. Slide the fan and wall box assembly into the framed opening in the wall. Attach the fan by inserting
a suitable fastener through each of the pre-punched mounting holes in the fan panel mounting flange. Care should be
taken not to bend or distort the fan panel or other components during installation. A distance of at least one and one-
half times the diameter of the fan should be allowed between the fan inlet or discharge opening and any adjacent wall
or large obstruction.
If a weather cowl is supplied on a supply fan, position the cowl over the opening on the exterior side of the wall, and
attach by inserting suitable fastener through each pre-punched mounting hole of the cowl mounting flange.

Personal Safety
Disconnect switches are recommended. Place the disconnect
switch near the fan in order that the power can be swiftly cut
off in case of an emergency, and in order that maintenance
personnel are provided complete control of the power source.
