BI SERIES – UTILITY BLOWERS

Operation Instructions & Parts Manual

MODELS: BI-10 – BI-36; BI-10RM – BI-36RM

READ AND SAVE THESE INSTRUCTIONS

GENERAL SAFETY

Rotating parts on fans should not be exposed. cabinets Where these components are not protected by ductwork, or

covers, appropriate guards should be employed to restrict exposure to rotating parts. Access doors should not be

opened with the fan operating to avoid foreign objects being drawn into the system. On initial start-up a careful

inspection should be carried out to ensure no foreign material is present which could become airborne in the system.

Read carefully or installation and operation instructions before attempting to install, operate service Canarm/Delhi

BI/BI –RM series blowers. Failure to comply with instructions could result in personal injury and/or property damage.

UNIT DESCRIPTION

Canarm/Delhi BI series blowers are specifically designed as a quiet and efficient blower. The BI series incorporates a

backwardly inclined (BI) blade configuration to generate air moving performance. The BI iser es are single inlet blowers,

which have a standard CCW rotation and bottom horizontal discharge. The discharge direction may be easily altered to

any one of eight positions without removal of venturi the wheel or housing.

Complete access for motor and drive installations and servicing may be completed by partial removal of the drive

compartment cover assembly. Pre-lubricated ball bearings, motor adjustment hardware and a dynamically balanced

wheel are standard equipment. Operating temperature range is - 65 to 220 deg. F.

UNIT DESCRIPTION

Inspect unit for damage and report any shipping damage to carrier. Check all fasteners and re-tighten as required. Rotate

the blower wheel by hand to ensure free rotation. If rubbing occurs, loosen the inlet venturi bolts, re-position the venturi

to establish clearance, re-tighten bolts.

IN TALLATIS ON

1. Secure the exhauster to the curb cap or sleepers (supplied by others) through the 3/4” diameter holes provided in the

base of the motor compartment and leg. For proper motor compartment ventilation, if the unit is mounted on a floor or

solid surface, provide a minimum 1” clearance to the motor cabinet bottom. Install spring isolators or duct isolators

where required.

2. Complete all subsequent duct connections.

3. Rotate the blower wheel by hand. It should not rub against the housing inlet. If rubbing occurs, loosen the setscrews

on the wheel hub and shift the wheel to obtain clearance. Re tighten all set- -screws.

4. Insert the four motor nuts and bolts up through the bottom of the sliding motor platform to match the bolting

configuration of the motor to be installed. The master hole for smaller motor frames is located at the top left hand

corner of the motor platform furthest from the blower housing. The master hole for 213T, 215T and 254T frame

motors is 2” inset from the fore mentioned master hole for smaller frame motors.

5. Mount the blower sheave on the blower shaft and tighten its set screw securely on the key of the shaft. (See Table 1 -

for drive data).

6. Mount the motor sheave on the motor shaft. Leave some clearance between the pulley and the motor end bell.

Tighten the set-screws on the key of the motor shaft.

7. With the motor platform in its highest position install the V belt within the sheave grooves. Ad ust the sheave on the j

blower shaft to ensure proper pulley alignment (see figure 2) and secure in place. A straight edge across the face of

the driven pulley should be parallel to the belt once proper alignment has been achieved.

WAR I GN N :

Excessive belt tension is the most frequent

cause of bearing wear and resulting noise.

Proper belt tension is critical for quiet, efficient

operation.

8. Loosen the four clamping bolts around the motor platform and slide the motor platform within the slotted rails to

adjust belt tension. Ideal belt tension is the lowest tension at which the belt will not slip during start up. As rule of

thumb suggests that 3/4” of deflection mid span under medium finger pressure (2 3 lbs.) for every foot of span is -

approximately proper belt tension. Tighten the motor platform clamping bolts once proper belt tension has been

achieved.

ELECTRICAL

WAR I GN N : Ensure power supply is disconnected and locked out prior to making electrical connections.

Before connecting the motor to the electrical supply, check the electrical characteristics and wiring instructions as

indicated on the motor nameplate or as shown below. Complete electrical connections as indicated.

WAR I GN N : A ground wire must be connected from the motor housing to a suitable electrical ground.

O OPERATI N

1. After electrical connections are completed, energize the unit momentarily and ensure that the rotation of the wheel is

correct. Apply full power.

2. With the air systems in full operation and all ducts and access panels attached, measure current input to the motor

and ensure that it is less than the rated full load motor amperage.

3. Proper ad ustment to the belt tension is critical for quiet efficient operation. j
