C. INSTALLATION
The installation instructions provide a general guideline for the
installation and wiring of the exhaust fan. All applicable codes must
be adhered to.
C.1 Location
1. For optimum air exhaust, the fan(s) should be installed as
follows:
1.1 There are no obstructions that may impede the fans
air inlet or discharge.
1.2 The air discharge is directed away from building.
1.3 The air discharge is not directed at a thermostat.
1.4 For warehouses or large workshops it may be
acceptable to use fewer, larger fans.
2. This unit can exhaust warm or cool air depending on customer
conditions. Be aware of problems each can produce.
3. For installation within a Hazardous Location, cable
entries and conduit should be suitable for operations in
hazardous locations and rated IP 54.
C.2 Mounting
1. The Exhaust Fan is designed to be installed in an upright
and level position.
2. Fan(s) are designed to be mounted from the rear using four
3/8" holes. For fan dimensions, see Figure 1, page5.
3. The mounting structure must be strong enough to:
3.1 Support the fans weight (refer to Section E. General
Specications, page7).
3.2 Provide sufcient stiffness to prevent excessive
vibration.
3.3 Withstand abusive situations such as transportable
installations.
3.4 If Exhaust Fan is installed on a wall thinner than 4",
customer will need to install shims to bring face of
fan away from mounting surface.
4. Mounting Clearances
4.1 Leave at least 20" (500mm) clearance between the
rear of the motor and the nearest obstruction.
4.2 Clearance equal to the height of the fan shroud
above, or beneath is required for easy fan or motor
replacement.
C.3 Temperature Control
If required, the fan output may be thermostatically controlled by a
remotely mounted thermostat.
C.4 Final Inspection
1. Before application of electrical power:
1.1 Check that all connections are secured and comply
with the applicable wiring diagram and code
requirements.
1.2 Conrm the power supply is compatible with the
data plate rotating on motor.
1.3 Remove any foreign objects from fan.
1.4 Ensure all electrical covers are well secured.
1.5 Ensure the fan rotates freely counterclockwise when
viewed from the rear of the fan and air exits through
the dampers.
