INSTALLATION, OPERATING AND MAINTENANCE INSTRUCTIONS
MODEL VGB A
SERIES BLOWER
CAUTION!
DO NOT INSTALL, USE OR OPERATE THIS EQUIPMENT UNTIL THIS MANUAL HAD BEEN READ AND UNDERSTOOD.
READ AND SAVE THESE SHEETS FOR FUTURE USE.
FORM 1501
RECEIVING INSPECTION:
Check for damage or missing parts immediately upon receipt. Ensure that wheel rotates freely.
REPORT ANY DAM-
AGE PROMPTLY TO CARRIER.
INSTALLATION:
Model VDBA series blowers are suitable for both suspension or base mounting.
SUSPENSION MOUNTING:
Drill 4 — 7/8” diameter holes through the top using the inside top “hat section” channel as a guide. Extend 1/2” diameter
threaded mounting rod through the cabinet and the bottom channel and secure to both top and bottom. Ensure unit is
level.
BASE MOUNTING:
For base mounting, secure the unit through 4 — 7/8” holes located in the “hat section” channel in the bottom of the unit.
Ensure unit is level.

MOTOR AND V-BELT DRIVES:
Mount motor with hardware provided and install pulleys and belt(s) with proper tension. Follow illustrated recommendations on belt installation on page 2.
BELT TENSION AND PULLEY ALIGNMENT:
1. Excessive belt tension is the number 1 cause of blower bearing failure.
2. Proper belt tension and pulley alignment are essential for trouble free operation.
3. A simple “Rule of Thumb” for checking belt tension is illustrated on page 2.
(Continued on next page)

4. When belt is grasped as shown on page 2, a total deflection of approximately 1” should be easily attained.
5. Insufficient deflection indicates that the belt is too tight, resulting in noise from excessive vibration, premature
bearing failure, and short belt life. Tight belts may overload a motor that would otherwise be adequate.
6. Excessive deflection is a indication that the belt is not tight enough. If not corrected, slippage could cause
loss of blower speed and belt failure through wear.
7. A belt should be just tight enough to avoid slippage.
8. Align pulleys with a straight edge to conserve belt life and eliminate unnecessary noise.
9. Check tension before start-up, after every pulley adjustment and regularly thereafter.
SET SCREWS:
Ensure all set screws on both pulleys and blower wheel are tight.
BELT SHOULD SQUEEZE
BY NO MORE THAN 1”
ELECTRICAL:
Connect motor in accordance with applicable codes. Provide properly sized motor overload protection to protect motor against electrical faults and system changes. Confirm proper motor rotation on star t-up.
MAINTENANCE:
Inspect periodically for mounting rigidity. Verify belt for wear and tension and adjust as required. Inspect wheel for any dust accumulation and clean as needed. Caution — Do not dislodge balancing clips. Check set screw for tightness.
LUBRICATION:
Insert bearings with sealed in lubricant are used on all 9200 ser ies models up to 15. No further lubrication is required. Models 18
and 20 use cast iron, pillow block, sealed type bearings. Re-lubrication is unnecessary under mot operating conditions. If lubrication
is required lubricant should be compatible to Esso Beacon #325.
