Step 2
Slide fan assembly into framed wall opening from outside
of the building. Insert top of fan into opening and hold fan
against top frame. Midpoint of top panel must be aligned
with frameing for bottom flange of fan to pass through
opening. See Figure 2. Secure top and bottom flanges to
wall using (6) Screws [A]. See Figure 3A.
Step 3
Left and right flanges must be bent outward over framing.
This can be done by hand or with a rubber mallet. Be
careful to bend along perforation and not to distort the
housing. See Figure 3B.
Step 4
Confirm that housing inside dimensions match those shown
in Figure 4A. Then secure left and right flanges to wall
using (10) Screws [A] (provided). See Figure 4B & 4C.
Step 5
Outlet of fan comes unguarded, install discharge cone
with guard on outlet of fan at this time. Refer to QM1049
for flat sided cone installation instructions.

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.
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 8A & 8B.
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 8B & 8C (page 8).
NOTE: A safety cut-off switch should be located adjacent to each fan.

3.2 Electrical Wiring
The Munters Drive fan ships configured for simple ON/OFF control. When electrical power is applied to
the main cable the fan will start and run at full speed. See Figure 9A .
To operate the Munters Drive On/Off with a control, Slide the ‘ON’ switch, located on the circuit board in
the junction box, away from the ON position. Now wire an ‘ON’ command from the ‘COMMON’ terminal
to the input relay in the control and from the output of the control relay to the ‘RUN’ terminal in the junction
box. See Figure 9A & 9B.
When making connections to junction 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 junction box wall to prevent water infiltration.

To operate the Munters Drive Off/Low/High with a control, slide the ‘ON’ switch, located on the circuit board
in the junction box, away from the ON position. Now wire an ‘ON’ command from the “COMMOM” terminal
to the input relay in the control and from the output of the relay to the ‘RUN’ terminal in the junction box. Then
connect the output of the control relay for ‘LOW’ to the ‘REDUCED FLOW’ in the junction box. See Figure 9C.
To Operate the Munters Drive variable with a 10-0V Signal. connect wires from the ‘0-10V IN’ and ‘0-10V
COMMON’ terminals in the Junction box to the 10-0V output in the control. See Figure 9D.

board in the junction box, away from the ON position. Now wire an ‘ON’ command from the ‘COMMON’
terminal to the input relay in the control and from the output of the control relay to the ‘RUN’ terminal in the
juction box. Also, connect wires from the ‘0-10V IN’ and ‘0-10V COMMON’ terminals in the junction box to
the 10-0V output in the control. See Figure 9E.

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. Turn on electrical power and
confirm that the fan operates smoothly.
2) ADJUSTMENTS: Set the fan control to the temperature shown on your
Aerotech ventilation system drawing, or to a value which will provide the
desired environmental conditions.
4.1 Operation
WARNING
!
Moving parts, disconnect power
before servicing.
4.2 Maintenance
WARNING
!
Moving parts, disconnect power
before servicing.
WARNING
!
High Voltage, disconnect power
before servicing.
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.
• DAMPER: Carefully clean dust from damper door and frame so that damper
door 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 connec-
tions. 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!

Caution: There is a 10 second
delay for the fan to start when
an 'On' command is present.
• Munters Drive motor/controller
issue
1. Verify AC voltage is present at fan.
2. Turn AC power off to fan for 1 minute
3. Verify Prop turns freely
a. If not contact Munters Product Support
b. If it turns freely go to next step
4. Turn AC power back on to fan

•Periodically observe fan to verify it is still running
•If it continues to run, fan is OK
•If fan stops, remove drive assembly cover to
check what drive display reads.
Contact Munters Product Support
b. If fan tries to start but stops, remove drive
assembly cover to check what drive display
reads. Contact Munters Product Support
c. If fan doesn't try to start, verify 'On' command
signal is present at circuit board. Also, slide the
switch on the circuit board to the 'On' position.
• Fan Operating - Insufficient
Airflow
• Excessive Noise
• Excessive Vibration
• Shutter or Damper door jammed
• Guard dirty/clogged
• 10-0V signal set incorrectly

5.1 Troubleshooting

QM1224r3
In most climates, it is probable that the ventilation system will never need to operate at a total capacity during the
colder winter months. Consequently, it is advisable to "winterize" those fans which will not be used in cold weather to
avoid unnecessary heat loss and condensation.
To winterize, turn fan control "off" and install an insulated closure panel over the fan intake. If you don't have an
insulated closure panel, a piece of rigid insulation material can be used. Remember the insulation panel must be
removed before warmer weather returns.
6.1 Winterizing
NOTE:
At least one single speed fan should be left uncovered and with power available to provide air
movement in the event of variable speed control difficulties.
Winterizing 6.
6.2 Winter Weather Protection
To prevent cone or fan damage from snow or ice sliding off building roof, weather protection must be
provided. A weather shelter may be constructed to cover the entire fan, See Figure 10, or snow guards
may be placed on the roof, See Figure 11
