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 V­belts if units are stored for an
extended period of time. V­Belts 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
