Electrical Wiring

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 6A. 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 6B.

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.

Electrical WiringChapter 3

Three Phase Fans:

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).

As the power cable exits the back of motor form a drip loop and then run power cable down along leg

of motor mount and "Zip" tie the cable to leg to prevent cable from getting tangled.

See Figure 7.

Then

run the cable out the drain hole to the circuit breaker or control panel. (Continued on next page).

3.1 Recommended Wire Routing:

Operation

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.

Maintenance

5.1 Maintenance

The following inspection and cleaning procedures should be performed monthly:

1) INSPECT PROPELLER: Check that propeller is secure on 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 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 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!

Winterizing

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 8, or snow guards may be

placed on the roof, See Figure 9.
