HRE SERIES – HORIZONTAL RESTAURANT EXHAUSTER
OPERATION INSTRUCTIONS AND PARTS MANUAL
MODELS: HRE-13, HRE-16, HRE-20, HRE-24
GENERAL SAFETY
Rotating parts on fans should not be exposed. Where these components are not protected by ductwork, cabinets 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 installation and operation instructions carefully before attempting to install, operate or service Delhi HRE Series
Blowers. Failure to comply with instructions could result in personal injury and/or property damage. Retain instructions
for future reference.
UNIT DESCRIPTION
Restaurant duty HRE Models are specifically designed as a quiet and efficient blower for vapor removal from commercial
cooking equipment. These backwardly inclined, single inlet blowers have a standard CW rotation and upblast discharge.
The blower housing is constructed from continuously welded 16 gauge steel, complete with tilted access and 2” drain for
cleaning.
Complete access for motor and drive installations and servicing may be completed by removal of the drive compartment
cover. Pre-lubricated ball bearings, curb cap, motor adjustment hardware and a dynamically balanced wheel are
standard equipment. Operating temperature range is –30 to 400 deg. F. For Unit dimensions, refer to Figure 1/Table 1.

GENERAL SAFETY INSTRUCTIONS
1. Always disconnect power source before working on or near a motor or its connected load. Lock the power
disconnect in the open position and tag to prevent unauthorized application of power.
2. Follow all local and national electrical and safety codes.
3. Blower must be electrically grounded. This can be accomplished by using a separate ground wire connected to
the bare metal of blower frame, or other suitable means.
4. Ensure that the power source conforms to the requirements of your equipment.
5. Do not put hands near or allow loose or hanging clothing to be near belts, pulleys, or blower wheel while the unit
is running.

UNPACKING
Once the packaging has been removed inspect the unit carefully. Check for loose, missing, or damaged parts. Rotate
the wheel by hand to ensure the wheel spins freely. Tighten all set screws.
INSTALLATION
1. Complete ductwork termination to the top of the curb per Figure 2.
Figure 2: Installation Method
Note: Check theinteriorof theblower housing. It should beclean and free of debris.
2. Hoist the exhauster onto the curb. This may be accomplished by attaching hooks into the eye hooks provided.
Do not lift unit by placing a sling around the shaft.
3. Position exhauster onto curb and secure using hinge kit provided in the parts bag. Note: Bottom bolt on hinge kit
should be tightened during operation and moved to the center hole when opened.
4. Rotate the blower wheel by hand. It should not rub against the housing inlet. If rubbing occurs, loosen the set
screws on the wheel hub and shift the wheel to obtain clearance. Retighten all set screws.
5. Insert the four 3/8” bolts through the slotted motor platform to match the bolting configuration of the motor to be
installed. Note: Loosely mount the motor to the sliding motor platform using the four 3/8” hex bolts, nuts and flat
washers provided.
6. 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)
7. 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.
8. With the motor positioned as close as possible to the blower shaft, install the V belt within the sheave grooves.
Adjust the sheave on the blower shaft to ensure proper pulley alignment (See Figure 3) 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. (see Figure 3)

Sep-07
WARNING: Excessivebelt tension is themost
frequent causeof bearingwearand resulting
noise. Proper belt tension is critical forquiet
efficient operation.
Figure 3: Pulley Alignment
9. Slide the motor within the slotted platform to adjust belt tension. Ideal belt tension is the lowest tension at which
the belt will not slip during start up. Belt should be adjusted to allow 1/4” to 3/16” of deflection per foot of belt
length. Tighten the motor mounting bolts once proper belt tension has been achieved.
10. Before connecting the motor to the electrical supply, check the electrical characteristics and wiring instructions
as indicated on the motor nameplate to ensure proper voltage and phase. Make your electrical connections.

OPERATION
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 adjustment to the belt tension is critical for quiet efficient operation.
MAINTENANCE
Ensure power supply is disconnected and locked out priorto performingmaintenance
1. Inspect and tighten the wheel set screw after the first 50 to 100 hours of operation and periodically thereafter.
2. Follow the motor manufacturer’s instructions for motor lubrication. Remove any excess lubrication.
3. Check the Drives:
a. Tighten set screws on sheaves, wheel and bearing locking collars.
b. Check belt tension and alignment.
c. Replace cracked or worn belts.
4. Check the wiring to be sure its secure and well insulated.
5. Blower bearings are pre-lubricated by the manufacturer. Generally, bearings should be lubricated at six to
twelve month intervals. The recommended lubricant is Shell Alvania #2 or S3. A small amount of grease should
be added slowly when the shaft is rotating. Note: Over greasing may cause damage to the bearing. Avoid
rupturing the bearing seal.
6. Inspect V-belts for wear and proper tension. If it is necessary to replace one belt on a multiple belt drive, replace
all the belts with a matched set. Do not use belt dressing.
7. Clean the blower wheel periodically. Material build up on the blades can cause wheel imbalance which may
result in wheel or bearing failure.
8. To reinstall replacement ball bearings, remove any burrs on the shaft with emery cloth or a fine file. Wipe shaft
with a clean cloth. Slide the bearing and housing on the shaft, position it and bolt pillow block securely to the
bearing support. Position the shaft to ensure the wheel properly fits to the inlet venturi. Alternatively tighten
each set screw with the proper hex head socket wrench until the wrench starts to spring.
9. Should further service to the blower be necessary, refer to the exploded view illustration (see Figure 4).
