Step 2B
If fan needs to be mounted, so that shutter does not stick into building then frame fan as shown in Figure 3 .
Top and sides require 4" minimum and bottom requires 2" minimum.
Step 2A
Insert fan into the framed opening from the inside. While lifting fan up tight to framing, fasten top of
fan with (3) Lag Screw [A].
See Figure 2A and 2B .Next, fasten bottom of fan, then both sides with
remaining (9) Lag Screw [A]. Install flashing around opening tight to fan and caulk around fan to seal.

Installing the one piece cone may require 2 people. If temperature is above 50°F then proceed to
Step 5.
If temperature is below 50°F then proceed to
Step 4.

Electrical Wiring 3.
3.1 Recommended Wire Routing
The Munters Drive Fan comes with a coil of electrical cable that is pre-wired to motor. Find the end of the cable
and route it outside the fan and connect it to the incoming power supply and/or the safety cut-off switch. (Safety
cut-off switch by others). See Figure 12A.

All wiring should be installed in accordance with National, State, and Local electrical
codes. Fans used to ventilate livestock buildings or other rooms where continuous air
movement is essential should be connected to individual electrical circuits, with a minimum
of two circuits per room. For electrical connection requirements, refer to diagram on motor
nameplate and to information enclosed with the environmental control to be used.
Single Phase and Three Phase Munters Drives: Power supply for fans to have Circuit
Breaker or Fuse Protection. The installer must refer to NEC and local codes to ensure
safety and compliance. See Figure 12B & 12C.
If recommended lightning protection was purchased, wire it to the fan power supply as shown and secure the
lightning protection unit near the disconnect or the bus panel. See Figure 12B & 12C.
NOTE: A safety cut-off switch should be located adjacent to each fan.

The Munters Drive fan ships configured for simple ON/OFF operation. When electrical power is applied to
the main cable and the ‘RUN’ Switch is in the ‘ON’ Position, the fan will start and run at full speed.
See Figure 13A.
***WARNING***
The Blue Box electrical enclosure must not be
removed from mounting bracket. Removing
Blue Box from the mounting bracket will void the
warranty. Any water or other damage to the
controller will not be covered if the Blue Box is

Electrical WiringChapter 3
When making connections to Munters Drive Box, be sure to use the supplied watertight fittings with only
1 cable per fitting. If watertight fittings are not used or if 2 cables or more are in 1 watertight fitting,
equipment failure from water damage will not be covered under warranty. If 2 or more cables are used in
1 watertight fitting, they must be sealed on both sides of Munters Drive Box wall to prevent water infiltration.
If you are going to run the Munters Drive with a signal from a control, carefully remove 6 screws and the
cover and save to reinstall later. Carefully punch the knock-out from the bottom of the Munters Drive Box and
install the Watertight connector as shown. See Figure 13B and 13C.

Operation and Maintenance 4.
1) INITIAL START-UP: With electrical power off, verify that the fan propeller
turns freely and that all fasteners are secure. With shutter in place, turn on
electrical power and confirm that the fan operates smoothly.
2) TEMPERATURE ADJUSTMENTS: Set the fan control to the temperature
shown on your Munters ventilation system drawing, or to a value which will
provide the desired environmental conditions.
4.1 Operation
WARNING
!
Moving parts, disconnect
power before servicing.
WARNING
!
High Voltage, disconnect
power before servicing.
WARNING
!
Do not power wash
electrical devices.
WARNING
!
Do not apply power
with shutter out.
4.2 Maintenance
The following inspection and cleaning procedures should be performed
monthly:
1) INSPECT PROPELLER: Check that propeller is secure on drive hub and that
there are no signs of damage. The blades are of a self-cleaning design and
should not require maintenance.
2) CLEAN regularly for best results:
• FAN MOTOR: Remove any dust accumulation from motor using a
brush or cloth. (DO NOT use a pressure washer). A clean motor will run
cooler and last longer. At the same time, verify that the motor is secure in
its mount.
• SHUTTER: Carefully clean dust from shutter and frame so that shutter
opens and closes freely. A brush or cloth should be used.
• GUARD: Clean any dust or feathers from fan guards using a brush.
Dirty guards can reduce airflow.
3) CHECK FASTENERS: For safety, all fasteners should be inspected. Tighten
any loose connections.
4) INSPECT FAN CONTROL: With power disconnected, inspect all electrical
connections. Wiring should be secure and in good condition. Remove any
dust build-up from control case and sensor using a soft brush or cloth.
NEVER CLEAN ELECTRICAL EQUIPMENT WITH A PRESSURE WASHER!
