(7b) Wiring Splits at Demounts:

1a. For shipping purposes, the liquid-tite conduit may have been secured to unit

casing with a strap. Remove and discard strap to free conduit.

2a. Remove electrical tape securing wires to liquid-tite conduit.
3a. Remove the screw from junction box.
4a. Insert the wires that are contained in the liquid-tite conduit into the liquid-tite

connector, then pull wire through box so that the liquid-tite conduit can be
fitted into the box connector.

5a. Slide the connector nut, that is installed on the conduit, to the connector and

thread nut on connector, then tighten.

6a. Determine the length of each wire needed, then cut and strip insulation.
7a. Install each stripped wire end into matching wire connector. If wire

connector is “IT” model, remove rubber plugs to access set screws. Once
wire is inserted, torque set screw to torque shown on drawing. Install rubber
access plugs and secure with electrical tape.

Note: Wires must be torqued and insulated stripped as shown.

The wire insulation on a properly installed wire must be
inside the insulated connector conductor port no less than
3/8 inch. Install access plus and secure plus with at least
two wraps of electrical tape across plus and around
connector body.

8a. Install the junction cover.

(8) Observe all pertinent local ordinances and codes covering installation and operation of air
handling equipment. Adequate clearance for the service and removal of components should be
provided (Do Not install unit in a tight space or dangerously close to roof edge especially on
access side).

O-ITF-07

(D) "START-UP" SERVICE

(1) After unit is permanently positioned, fan isolation shipping lock-down bolt, only (see drawing), should

be removed. If load points are not on same plane after supports are removed readjust isolator or shim
until elevation of load points are uniform.

Larger Drawing

Manual

(2) Access door to piping compartment is provided if pipe chase is furnished. All plumbing in field
should be done through chase (Do Not puncture casing). Use back-up wrenches on stubouts and
swing joint piping or flex piping to avoid damage to headers and tubes. If, for any reason, it is
necessary to cut a hole in the unit casing, this hole should be cut through a side panel (not
through any access door) and then carefully sealed. If vestibule is furnished all piping should be
run inside the vestibule and plumbed through the chase hole cover plate. Access door to
vestibule or chase compartment should be closed and latched securely to avoid plumbing freeze
up.

(3) Vault type door latches provided on access doors can be adjusted by changing position of bevelled
flange or handle on inside. Access door gasketing must not be removable or leakage of air and
water could result.

(4) Check motor mounting to make sure all nuts are tight. Confirm that the motor voltage, phase,
and HP size are compatible with wiring. Motor nameplate amperage is maximum. All electrical
connections should be tight, complete and properly terminated.

(5) Supply and return air duct flanges are provided and should be attached to ducts with flexible
connector unless fans are internally isolated. Multizone units require field zo ning of individual
zone segments by use of "W" clips which attach to zone separators.

(6) Fan blower wheels should rotate freely. Check motor and fan sheave for proper alignment and
make sure set screws are tight. Check bearing-collar set screws on fan shaft and fan hub set
screws for tightness. Loose collars and/or set screws will ruin the shaft quickly. Ball bearings
have been lubricated at the factory and do not need further attention at start-up. Do Not operate
fans with imbalance. During fan (supply and return) start-up observe the rotation and if fan is
operating backward, reverse two legs of the supply electrical power if three phase.

O-ITF-07

Page 8

(7) Rotate damper (Face & Bypass, Outside Air, Return Air, Exhaust and Zone Dampers) shafts to
test action; rough handling may have caused damper blades to bind. Damper shaft extension
(1/2" shaft) is provided to accept manual or automatic controls. Do Not overdrive damper
motors, this will deform dampers and/or linkage.

(8) Outside air inlet hood and exhaust outlets (if not mounted when shipped) have been predrilled for

attachment in field. After mounting, hoods should be caulked for weatherizing. Both the hood
and the outlets include birdscreen and louvers.

(9) Filters (when furnished by TEMTROL, INC.) are often furnished and mounted in the racks or in
boxes inside the unit. Check to make sure the filter cartridge count is correct. (Filter count is
found on the Data Sheet). If filter count is short, the exact number received should be noted on
the freight bill at the time of delivery. Check to make sure that filter media has been installed
properly in the rails. Check to be sure that the filters called for are used; failure to use the filters
that your TEMTROL, INC. Air Handler has been designed for can cause fan motor overload
and/or cause the coils to become dirty and restrict airflow. Filter access doors should always be
latched firmly to stop air by-pass around filter cartridges.

(10) Check all screws, bolts, nuts, electrical and piping connections for tightness.

(11) If unit heaters are provided check thermostat settings to insure freeze protection.

(12) Supply and return fan drives are provided in the mid-speed adjustment range when variable
speed sheaves are furnished. The motor sheave pitch diameter is field adjustable for the required
air flow. When final adjustments are complete the current draw of the motor should be checked
and compared to full load amperage rating of the motor. After supply fan is set, the return fan
drives should be adjustable for proper pressurization of the building. Sheaves with two or more
grooves should be adjusted by the same number of 1/2 or full turns from closed position to insure
the same pitch diameter so belts bear equal load. DO NOT FORCE BELT OVER THE
GROOVES. Hub type fan sheaves are furnished. Sheaves must be tightened securely before
drive is operated.

(13) Hinged or slide rail motor mounts are furnished with two adjusting bolts. Bolts must be adjusted
equally or so drives maintain proper alignment. Correct belt tension should be acquired by use of
belt tension checker tool. Over tightened belts reduce belt and bearing life substantially, yet belts
must be tight enough to prevent slippage.

(14) Humidifiers if installed include operator, trap, strainer and manifold mounted or furnished and
mounted by contractor. Supply steam connects at top to strainer and return connects at leaving
side of trap. Piping to and from humidifier should not be reduced in size with pitch (of 1/2" in
10') length without sag.

(15) After 24 hours operation re-check "start-up" items.

(16) See Prestart and Operation Check Sheet.

O-ITF-07

(E) MAINTENANCE AND INSPECTION SERVICES

(1) FAN - Check blades for dirt and/or grease build-up especially on concave sides. Check set screws
and/or set collars of fan wheel and bearings for tightness. Check bearing mounting bolts and fan
housing cut off blade bolts and nuts for tightness. If fans are furnished with housing drains, see
that "weep holes" in bottom are open. If housing access door is furnished be sure it is properly
sealed and latched. Remove all debris from fan section and unit in general.

(2) BEARINGS AND SHAFT - Ball or Roller bearings are greased at the factory and therefore ready
to run at "start-up"; however routine maintenance and inspection is required there after. Normal
operation of bearings are "cool or warm to touch". High bearing temperature accompanied by
excessive leakage of grease indicates too much grease. High temperature with no grease showing
at the seals, particularly if the bearing seams noisy, indicates too little grease. If running
discloses an excessive amount of grease in the bearings the grease fittings should be removed
until the excess has escaped. Fan shafts should be coated to prevent corrosion yet check
that dirt or debris build-up is not accumulating which could affect balance.

(3) FAN BEARING LUBRICATION - Lubrication intervals vary with the period of operation and
temperature of the air. Do Not Over-Lubricate. The bearing is factory lubricated with Lithium
based grease of NGL1#2 consistency, such as Sinclair Litholene Multipurpose, Avalinia #2,
Texaco Multifax #2, Humble Lidok #2, Mobil Armyac#781 or Phillips Philube L2.

(4) MOTOR AND MOTOR BEARINGS - Check for dirt and debris accumulation on "air travel"
openings of open type motors to prevent overheating. Relubricate motor bearings every 2000
hours of operation while it is warm and at a stand still. Remove and clean upper and lower
grease plugs. Insert grease fittings into upper hole adding a small amount of clean grease with a
low pressure gun. Run motor 5 minutes before replacing plugs. Excessive grease will overheat
the bearings. Use only high grade mineral grease having a 200 degrees F safe operating
temperature. (If special lubrication instructions are shown on the motor nameplate they will
supersede all other instructions).

(5) SHEAVES - After air balance, require no further adjustment. However, sheave locking devices,
wear, alignment and belt tension should be checked on a regular basis.

(6) DAMPER BLADES AND LINKAGE - should be inspected regularly for dirt and/or debris build
up to insure abnormal wear or damage does not occur. Winterize damper system prior to cold
weather to insure that proper sequence of control is being maintained, paying close
attention to operation of outside air intake. Outside air damper should be checked closely for
minimal leakage when closed.

(7) OUTSIDE AIR INTAKE HOOD - should be checked for debris in birdscreen and/or obstructions
to air flow (such as old boxes, new walls or fences, etc.) around unit. Clean or remove as
required.

(8) WATER COILS - (Heating and Cooling) if not antifreeze protected or heater protected should be
drained as thoroughly as possible and then treated in the following manner:

Fill each coil independently with an antifreeze solution
using a small circulating pump and again drain. Check
freezing point of antifreeze before proceeding to next
coil. Due to a small amount of water always remaining in
each coil, there will be a diluting effect. The small
amount of antifreeze solution remaining in coil must
always be concentrated enough to prevent freeze-up.
Carefully read instruction for mixing antifreeze solution
used. Some products will have a higher freezing point in
its natural state than when mixed with water.

Failure of controls, outside air dampers and air stratification can cause freeze-up and permanent
coil damage if above precautions are not observed. Do Not allow dirt to accumulate between the
fins of coils. Use water, steam or air to remove dirt.

(9) STEAM COIL - fins should be cleaned in the same manner as Water Coils. Steam lines to and
from unit should be checked for pitch, pipe sag and blockage to avoid "Water-hammer".
Strainers and traps require annual cleaning minimum.

(10) CONDENSATE PAN - should be checked for dirt and debris build-up and cleaned. Trap and
drain should also be cleaned especially if blockage is evident.

O-ITF-07

Page 14

(11) FILTER ASSEMBLY - tracks should be checked for rail seal retention where required and all rails
should be cleaned annually to control dirt build-up, filter drag and dust by-pass during change
out of media. Dirty filters reduce the air volume handled by the unit, and thereby its capacity.
Unit should not be run without proper filters or fan motor overload, dirty coil and restricted air
flow will result. Proper media retainers should be used at all times to avoid possible media
"blow-out", which can cause blockage of air flow and/or damage rotating fan and motor parts.
Do not operate media beyond its rated capacities before change out or "blow-out" damage
can result.

(12) CASING AND ACCESS DOORS - should be checked for leakage (air and/or water). Door gasket
must be in proper alignment and if damaged, should be replaced. Inside access panels must be
latched properly to avoid air recirculation.

Page 15

(13) COILS - can be removed from unit through either end of unit. After removing piping and end
panels, remove bolts holding coil to structural frame at the air entering side of coil. The coil and
casing can then be pulled out.

(14) WIRING AND COMPONENTS - should be made and remain in accordance with National, State
and local codes that apply to this equipment. Check connections of wiring and retighten so
danger of a poor connection causing overheating and component failure through inadequate
current handling can be avoided. Good practice and safety indicates that before attempting
service to components, de-energize the systems and only after workers are clear of rotating and
electrical devices can unit be energized again.

(15) ULTRAVIOLET (UV) GERMICIDAL IRRADIATION LIGHTS – The United States Environmental

Protection Agency (EPA) believes that molds and bacteria inside buildings have potential to cause
health problems in sensitive individuals
as a factory-engineered and installed option in select commercial air handling products.

When UV lights are factory provided, polymer materials that are susceptible to deterioration by the
UV-C light will be substituted or shielded from direct exposure to the light. In addition, UVC­radiation can damage human tissue, namely eyes and skin. To reduce the potential for inadvertent
exposure to the lights by operating and maintenance personnel, electrical interlocks that automatically
disconnect power to the lights are provided at all unit entry points to equipment where lights are
located.

WARNING

!

Equipment Damage, And Personal Safety Risk, From Ultraviolet (UV) Lights!

Temtrol does not recommend field installation of ultraviolet lights in its air handling
equipment for the intended purpose of improving indoor air quality. High intensity
C-band ultraviolet light known to severely damage polymer (plastic) materials and
poses a personal safety risk to anyone exposed to the light without proper personal
protective equipment (can cause damage to eyes and skin). Polymer materials
commonly found in HVAC equipment that may be susceptible include insulation on
electrical wiring, fan belts, thermal insulation, various fasteners and bushings.
Degradation of these materials can result in serious damage to the equipment.

Temtrol accepts no responsibility for the performance or operation of our air
handling equipment in which ultraviolet devices were in stalled outside of the
Temtrol factory.

(16) AIR FILTER GAUGE - "pick-ups" should point against air flow for best results without
restriction. Oil Manometers require split to operate properly (check zero set).

(17) HUMIDIFIER - strainer screen in supply line should be cleaned a few days after put in operation
and thereafter at least once a season - more often if much dirt is found in the screen. The trap
should be inspected at the same time strainer is cleaned.

(18) UNIT HEATER OR ELECTRIC COIL - should be checked for dirt on resisters and removed by
use of air only. DO NOT attempt cleaning without positive shut down.

(19) PNEUMATIC OPERATORS - and linkage should be inspected for sequence and travel and
vacuum hose leaks especially prior to cold weather usage where furnished.

(20) OTHER COMPONENTS - not mentioned should be maintained per instructions attached to
component.

(21) REPLACEMENT PART - (if required) orders for service or replacement must include serial
number, model number and unit tag of unit as stamped on serial plate, attached to unit. If
replacement parts are required, state date of installation of unit, date of start-up and date of
failure, along with an explanation of the malfunction and a description of the replacement parts
required. Goods may not be returned except by permission of authorized factory officials of
