TP HIGH VELOCITY FANS
INSTALLATION, OPERATING & MAINTENANCE
These instructions provide proper installation and
maintenance instructions for Triangle Engineering
products. Proper installation, operation and maintenance
will assure efficient and dependable performance. Improper
use or installation may result in personal injury or property
damage. Trained and experienced personnel should install
according to manufacturer’s instructions and in compliance
with federal, state and local government.
RETAIN THESE INSTRUCTIONS FOR FUTURE
REFERENCE. READ ALL INSTRUCTIONS THOROUGHLY
BEFORE PROCEEDING.
RECEIVING, HANDLING AND STORAGE
Our TP Fans are carefully inspected before leaving the
factory. When the unit is received, on-site inspection should
be made. The unit is factory balanced, all components 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 of Arkansas, Inc. 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 lubrication.
INSTALLATION
POSITIONING AND RUNNING POWER LINES: Normally,
power is brought up from within the building through proper
conduit lines to the proper connections.

START-UP AND OPERATION
Careful inspection should be made before start-up. All
fasteners should be securely tightened. Impeller should be
rotated by hand to insure free movement. (NOTE: Before
placing hand on propeller, lock out primary and secondary
power source). Check all set-screws and keys. Tighten
where necessary.
WARNING - The fan 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.
1. Check rotating members for adequate clearance.
3. Check installation and anchoring.
4. Check motor bearings.
The fan guards should be free from obstructions. To
assure maximum air movement an adequate supply air must
be available.
Power lines compatible with the motor requirements
are brought up from an electrical source to the unit. A
generous amount of slack in power lines should be provided
to allow for motor deflections. Motor must be securely
and adequately grounded. Protect power lines from sharp
objects. Do not kink power line or permit it to contact hot
surfaces, chemicals, grease or oil.
Before putting any fan into operation, the following check
list should also be completed:
a. Lock out primary and secondary power source.
b. Make sure installation is in accordance with manufac-
turer’s instructions.
c. Check and tighten all fasteners.
d. Spin propeller to see if rotation is free and does not
bind or rub.
e. Check all set-screws and keys and tighten if neces
sary.
f. Make sure there is no foreign loose material in fan
guards or propeller.
g. Properly secure all safety guards.
h. Check line voltage with motor nameplate.
i. Check wiring. (NOTE: On single phase motors, the
terminal block must be set up in accordance with
the nameplate instructions and/or wiring diagram.
The set-up must match the line voltage. If the motor
is 3 phase, the winding leads must be grouped and
connected as shown on the wiring diagram. The line
voltage must correspond with proper grouping of
motor leads. On 2-speed motors the wiring diagram
must be followed precisely or serious motor damage
will occur.)
-
Switch on electrical supply and allow fan to reach full
speed. If heater elements are tripping out the starters, the
following items should be investigated:
Is the heater element the correct size for the 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 suit the line voltage?
Check carefully for:
1. Correct rotation of the propeller. (NOTE: Incorrect rotation overloads motor severely and results in serious
motor damage. To change rotation of 3 phase units,
simply interchange any two of the three line leads. On
single phase units, change the terminal block set-up
following the wiring diagram.)
2. Check motor and bearing temperatures so that they
are not excessively hot. (NOTE: Use care when touching the exterior of an operating motor. Modern motors
normally run hot. They are designed to operate at higher
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.
The fan may now be put into operation but during the
first eight (8) hours of running it should be periodically
observed and checked for excessive vibration or noise. At
this time checks should be made on motor input current
and motor bearing temperatures to insure they do not
exceed manufacturer’s recommendations. After eight hours
of satisfactory operation, the fan should be shut down and
the electrical power locked out to check the following items
and adjust if necessary:
a. All set-screws, keys and fasteners.
b. Drive coupling alignment.
NOTE
• Care should be taken to follow all local electrical, safety
and building codes.
• Provisions of the National Electrical Code, as well as
the Occupational Safety and Health Acts should be followed.
• All motors are checked prior to shipment; however,
if motor defects should develop, prompt service can
be obtained from the nearest authorized service sta-
Page 3
tion of the Motor Manufacturer while under warranty.
Exchange, repair or replacement will be provided on a
no charge basis if the motor is defective within the warranty period. The Triangle representative in your area
will provide a name and address of an authorized ser
vice station if requested. Do not return defective motors
to Triangle Engineering. WARNING: Motor guarantee is
void unless overload protection is provided in motor
wiring circuit.
MAINTENANCE
Do not attempt any maintenance on a fan unless the
electrical supply has been completely disconnected. If a
disconnect switch has not been provided, remove all fuses
from the circuit and lock the fuse panel so they cannot be
accidentally replaced.
Lubrication is a primary maintenance responsibility. All
bearings should be checked periodically. If the fan is installed
in a corrosive or dirty atmosphere, the propeller, inlet and
other moving parts should be cleaned periodically.

LUBRICATION SCHEDULE:
a. Under average conditions where ambient temperatures
do not exceed 120°F, lubrication is required once or
twice a year.
b. Under a dirt laden atmosphere where there is a tempera-
ture range from 10°F. to 120°F, lubrication is required
from three to six times a year.
c. Under extreme temperature conditions and extremely
dirty atmospheres, lubrication should be scheduled at
least once or twice a month.
PARTS REPLACEMENT: If replacing parts, do so with
properly selected components, which duplicate original
parts correctly. Incorrectly sized parts can damage the fan
.
SPECIAL PURPOSE SYSTEMS
Explosive, corrosive, high temperature, etc.
conditions may require special construction, inspection
and maintenance. It is necessary to observe the fan
manufacturer’s recommendations and limitation concerning
the type of material to be handled by the fan and its
application to special conditions.
THE HIDDEN DANGER
In addition to the normal dangers of rotating machinery,
fans present an additional hazard in their ability to suck in
not only air, but loose material as well. Solid objects can
pass through the fan and be discharged by the propeller as
potentially dangerous projectiles.
When a fan is being started for the first time, a complete
inspection of the fan should be made (with the power locked
off).
MOTOR LUBRICATION: In general, standard motors
that are furnished have prelubricated, sealed-for-life ball
bearings which require no lubrication for seven to ten
years of normal service. In cases where motors have been
ordered with greasable bearings, these bearings have been
lubricated at the factory and do not require any attention for
one year under normal conditions. If the particular motor
is equipped with grease relief fittings, these should be
removed to allow old grease to flow out when maintenance
is performed. Whenever possible, grease should be applied
while the motor is running. This practice should not
supersede any safety consideration. DO NOT OVER GREASE
- as most lubricants deteriorate motor windings, thereby
reducing motor life.
IMPORTANT: Use low pressure grease guns only. High
pressure guns tend to blow out or unseat bearing seals,
leaving the bearing open to collect grime, dust and foreign
particles.
FAN GUARDS
All fans have moving parts which require guarding in
the same way as other moving machinery. In areas which
are accessible only to experienced personnel, a standard
industrial type guard is required. This type of guard will
prevent the entry of thrown or dropped objects with a
minimum restriction of air flow.
Where the fan is accessible to untrained personnel or
the general public, maximum safety guards should be used,
even at the cost of some loss of performance. Fans located
less than 7’ above the floor require special consideration as
specified in the Occupational Safety and Health Act.
