UPBLAST and HOODED FANS

INSTALLATION, OPERATING AND MAINTENANCE

INSTRUCTIONS FOR ALL PANEL FANS

This data sheet provides proper installation and

maintenance instructions. Proper installation, operation and

maintenance will assure efficient and dependable perfor-

mance. Improper use or installation may result in personal

injury or property damage. Trained and experience personnel

should perform the installation according to manufacturer’s

instructions and in compliance with federal, state and local

government requirements.

READ ALL INSTRUCTIONS THOROUGHLY BEFORE

PROCEEDING.

RECEIVING HANDLING AND STORAGE

Upblast and Hooded Fans have been carefully inspected

before leaving the factory. When the unit is factory balanced,

all components (propeller, shaft, bearings, etc.) have been

tested prior to shipment. Units have been given an operating

and running test before leaving the factory. Units which are

mishandled can void the warranty provisions. If units have

been damaged in transit, it is the responsibility of the receiver

to make all claims against the carrier, Triangle Engineering is

not responsible for damages incurred during shipment.

Units should be handled with care to prevent possible

damage. Avoid jarring and/or dropping. Units which are

supplied with special painted or coated finishes should be

handled with care to protect the surfaces. If the continuity of

the coating is scratched and damaged due to mishandling, the

protective coating may be adversely affected.

Long term storage requires special attention. All units

should be stored on a level, solid surface (preferably indoors).

If outdoor storage is necessary, provide protection against

moisture and dirt. Protect all bearings and shafts with

lubricant and encase the entire unit in plastic or some

similar weatherproof material. To prevent deterioration of

lubricants, special finishes, etc., periodic inspections should

be made. During these inspections, it is good practice to

rotate the propeller by hand to spread bearing lubrications.

It is advisable to remove V-belts if units are stored for an

extended period of time. V-Belts which remain under tension

in a stationary position for extended periods are likely to have

reduced operating life.

INSTALLATION

INSTALLING THE LOUVER DAMPERS: When required,

dampers should be installed prior to mounting the unit on the

curb. Dampers must be secured without undue twisting which

may distort louver frame. Louver frame must be reasonably

level on all sides. Check for free operation. If louvers are motor

operated type, ascertain that proper voltage is impressed on

motor terminals.

ANCHORING OR SECURING THE VENTILATOR:

Whenever possible anchoring should be accomplished by

fastening through the vertical portion of the mounting flange.

The type, size and number of fasteners depends upon the unit

size and curb construction. If fastening is prescribed by code

or specification to be done through top (horizontal portion)

of mounting flange, then neoprene or lead washers should

be used under the head of each fastener. LARGE UNITS

INSTALLED ON TALL BUILDINGS OR IN AREAS SUBJECT

TO HIGH WINDS REQUIRE ADDITIONAL FASTENING

WITH GUY WIRES. If the contractor removes ventilator parts

to facilitate installation and electrical connections, all parts

should be reassembled by replacing all spacers, washers,

nuts, bolts, fasteners and components exactly as they were

found prior to removal. All fasteners are to be drawn tight and

secure. The ventilator is now ready for service.

CHECK LIST

If heater elements are tripping out the starters, the following

items should be investigated:

Is the heater element the correct size for motor?

Is the starter located in a high ambient temperature?

Is the propeller rotating in the correct direction?

Is the line voltage excessively low?

Is the motor wired properly to suite the line voltage?

The ventilator has been checked at the factory prior to

shipment for mechanical noises. If mechanical noise should

develop then some suggestions are offered here as a guide toward remedying the cause. Check rotating members for adequate clearance. Check proper belt tension and pulley alignment. Check installation and anchoring. Check fan bearings. START-UP AND OPERATION Careful inspection should be made before start-up. All motor bearings should be properly lubricated, all fasteners should be securely tightened. Impeller should be rotated by hand to insure free movement.

temperatures. This is a normal condition, but they may be hot enough to be painful or injurious to the touch.) If any problem is indicated, SWITCH OFF IMMEDIATELY. Lock out the electrical supply and check carefully for the cause of the trouble and correct as needed. Even if the fan appears to be operating satisfactorily, shut down after a brief period and check all fasteners, set-screws and keys for tightness.

Access doors to a duct system should never be opened when the fan is running. On the downstream (or pressure) side of the system, releasing the door with the system in operation may result in an explosive opening. On the upstream (or suction) side, the inflow may be sufficient to suck tools, clothing, etc., and may even cause a man to lose his balance.
