Construct the framed opening to correct size according to the Chart A (below).
See Figure 1A and Chart A. If fan and housing is to be framed into a 2 x 4 wall
or concrete wall, See Figure 1A, 1B, 1C and Chart A for details. For greater than
4" wall thicknesses, See Figure 1D.

Installation InstructionsChapter 2
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 framing for bottom flange of fan to pass through
opening. See Figure 2. Secure top and bottom flanges to
wall using (6) Lag Screws [A] (provided). 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) Lag Screws [A] (provided).
See Figure 4B and 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.

Electrical Wiring 3.
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 Munters environmental control to be used. After wiring
check for proper motor rotation.
Single Phase Fans: motor overload protection should be provided for each fan. A Circuit Breaker Switch or slow
blow motor type fuses must be used, See Figure 5A. See form QM1400 for proper size.
Three Phase Fans: motor overload protection should be provided for each fan. A three-pole motor starter or slow
blow motor fuses must be used. See Figure 5B.
If a frequency drive (inverter) is used, confirm that motors are rated for inverter duty at the voltage used. Shielded
power cable between frequency drive and each motor is highly recommended. Installation of line reactors is
recommended to reduce voltage spikes and harmonic distortion. Supplemental motor overload protection is also
recommended.
NOTE: A safety cut-off switch should be located adjacent to each fan.

As the power cable exits the back of motor, form a drip loop and then run cable up through fan
housing and frame into wall cavity and into building. See Figure 7A and 7B.

Operation 4.
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.
ADJUSTMENTS: Set the fan control to the temperature shown on your ventilations system
drawing, or to a value which will provide the desired environmental conditions.
Single Phase Fans: When variable speed controls are used, the fan's idle speed will need
to be set to the recommended minimum airflow rate. Refer to the procedures included with
each control. The table below provides airflow rates at various propeller speeds for fans
wired for 240 VAC.
Three Phase Fans:
1) The use of a quality frequency drive and the installation of line reactors is
recommended to reduce voltage spikes and harmonic distortion.
2) Minimum operating frequency of 30 Hz.
3) Will require three pole contractors with overload protection (by others).

Maintenance 5.
5.1 Maintenance
The following inspection and cleaning procedures should be performed monthly:
Tools Needed for Maintenance:
wrenches: 10mm, 13mm, 17mm, 27mm
1) INSPECT PROPELLER: Check that propeller is secure on prop shaft or motor shaft
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 blades and frame so that blades
open and close 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 1 month after
initial operation and yearly thereafter. 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!

MaintenanceChapter 5
5) CHECK DRIVE ALIGNMENT: Check to make sure the belt is
centered on the idler pulley, then use a straight edge to check
the alignment of the drive pulleys. If an adjustment is needed,
remove the belt, then loosen the set screw in one pulley and move
it. Remember to tighten the set screw after making an adjustment.
Drive alignment is very important for long belt life and proper
operation.
6) CHECKING PULLEYS: Roll the belt off and look at both pulleys.
If the pulley has grooves in it or is no longer smooth, it needs
replacement. A loose or slipping belt will reduce fan performance
up to 60% and cause premature belt failure.
7) BELT TIGHTENING: To adjust belt tensioner to the proper setting, loosen 10 mm bolt (using
17mm end wrench) to allow tensioner arm to rotate. Working from inlet/motor side of fan,
place a 27 mm (11⁄16”) wrench onto the hex on tensioner. Turn wrench clockwise until the
single mark on base of belt tensioner is aligned with Mark 2¹⁄₂ on the tensioner arm. Hold
tensioner at this setting and tighten 10mm bolt to 40 ft.-lbs [54 N-m] torque.

Winterizing 6.
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”. Install the 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.
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.
6.1 Winterizing
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 9, or snow guards may
be placed on the roof, See Figure 10.
Note: Snow guards are designed to prevent sudden, dangerous snow
and ice slides when attached to the building roof according to
manufacturers recommendations. The supplier listing above is given
as a reference only. Munters does not endorse any specific snow
guard product and no performance warranty is implied.

Warranties do not cover cone or fan
damage from external sources.
