3.1 Recommended Wire Routing:

The Munters Drive Kit comes with a coil of electrical cable that is pre-wired to controller. Find the end of the

cable and route the cable up the strut and out of the fan. Create a drip loop in the bottom of the cable and

then fasten it to the strut using (4) Wire Clamps [H] and TEK Screws [G]. Attach the new cable to the power

supply for the fan. See Figure 11A and 11B. Continue on next page

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 11B and 11C.

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 11B and 11C.

NOTE: A safety cut-off switch should be located adjacent to each fan.

Default Operation Full Speed

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 12A.

***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

removed.

***NOTE***

All Low Voltage wire must be shielded

cable. i.e. Belden 8770 or equivalent.

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 12B and 12C.

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

Operation and Maintenance

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.

• 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 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!
