Receiving, Inspection & Unpacking

General Installation

When the equipment is received all items should be

carefully checked against the bill of lading to be sure all

crates and cartons have been received. Before accept-

ing delivery, carefully inspect each carton or crate for

visible shipping damage. If any damage is noticed, the

carrier should make the proper notation on the delivery

receipt acknowledging the damage. Make notations of all

damage on all copies of the bill of lading and have all

copies countersigned by the delivering carrier. The car-

rier should also fill out a Carrier Inspection Report. The

factory Traffic Department should then be contacted.

File claim for damage with the carrier. Physical damage

to the unit after acceptance is not the responsibility of

Aerovent.

Unpack each carton or crate and verify that all required

parts and proper quantities of each item have been

received. Refer to drawings for part descriptions. Report

shortages or missing items to your local representative

to arrange for replacement parts.

Due to availability of carriers and truck space, it is not

possible to guarantee that all items will be shipped

together. Verification of shipments must be limited to

only those items on the bill of lading.

The unit nameplate must be checked to make sure the

voltage agrees with the power supply available.

CAUTION: Sheet metal parts, screws, clips and similar

items inherently have sharp edges, and it is necessary

that the installer and service personnel exercise

caution.

The installation of this equipment shall be in accordance

with the regulations of authorities having jurisdiction and

all applicable codes.

This equipment is to be installed by an experienced

installation company and fully trained personnel.

The mechanical installation of the exhaust ventilator con-

sists of making final connections between the unit and

building services, duct connections.

Electrical Connection 1. Connect supply wiring to the disconnect switch (non-fused standard). Check the wiring diagrams on the motor for connections. 2. The motor is factory set at the voltage marked on the fan nameplate. Check the line voltage with the nameplate voltage and wiring diagrams. 3. The main power wiring should be sized for the ampacity shown on the dataplate. Size wires in accordance with the ampacity tables in Article 310 of the National Electrical Code.

V-Belts V-belts on these belt driven fans are oil, heat, and static resistant type and oversized for continuous duty. With proper installation and maintenance, years of operating efficiency can be added to the lifespan of the V-belt drive. The condition of V-belts and the amount of belt tension should be checked prior to start-up (see Figure 4). When it becomes necessary to adjust belt tension, do not over-tension as bearing damage will occur.

Three-Pulley (Idler Sheave) Assembly Single bolt belt adjustment (Figure 9) can be made by loosening the idler sheave bolt (with 3/4" wrenches) and moving it to the point where proper tension is achieved, per Page 8, Figure 5. Alignment is necessary prior to belt adjustment. See Figure 6. Figure 9. Three-Pulley (Idler Sheave) Assembly IDLER SHEAVE FAN SHEAVE This configuration is standard on ACX sizes 070-160 and ATB (family) sizes 110-180. All other adjustments are made by moving the motor.

12. The standard pillow block bearings on belt driven ventilators are factory lubricated and are provided with external grease fittings. Lubrication annually is recommended, or more frequently if needed (see Table 5). It is recommended to add fresh grease at startup, but do not over-grease. Use only 1 or 2 shots of a recommended lubricant with a hand gun in most cases (see Table 6). Maximum hand gun rating 40 P.S.I. Rotate bearings during lubrication where good safety practice permits.
