Clearances

Combination Units I

Access Panels

The location MUST allow for minimum clearances and
should not be adjacent to a patio or other area where the
unit's operating sound level might be objectionable.

Clearances MUST be maintained from adjacent structures
to provide adequate fire protection and room for service per-

sonnel.

NOTE: Filter racks need a 26" minimum clearance at front of
unit for removal offilters. See chart below if unit isgoing to be
placed near combustible construction or materials.

While minimum clearances are acceptable for safety rea-
sons, they may not allow adequate air circulation around the

unit for proper operation in the cooling mode. Whenever
possible, it is desirable to allow additional clearance, espe-

cially around the condenser inlet and discharge openings.

Do NOT install the unit in a location that will permit dis-
charged air from the condenser to recirculate to the con-

denser inlet.

CAUTION

Do NOT operate unit in a corrosive atmosphere contain-
ing chlorine, fluorine, or any other corrosive chemicals.

5. Air Distribution System

Ductwork

NOTE: The total heat loss from the structure as expressed in

total Btu/hr(Kw) MUST be calculated by manufacturer's

method or in accordance with "A.S.H.R.A.E. Guide" or
"Manual N - Load Calculations" published by the Air Condi-
tioning Contractors ofAmerica or in Canada H.R.A.I. "Manu-

al N". The total heat loss calculated should be equal to or

less than the unit heating capacity, output based on D.O.E.
test procedures, steady state efficiency times input.

Ductwork, supply registers, and return air grilles MUST be
designed and sized to handle the greater of the units heating

or cooling airvolume requirements. If the unit isconnected to
an existing system, the ductwork MUST be checked to make

sure it is adequate. Extra runs or larger duct sizes may have
to be installed. Use only non-combustible type insula-

tion on supply plenum or supply ductwork within 6
feet(2m) of unit,

Maximum recommended velocity in supply trunk ducts is

1000 feet (305m) per minute and 800 feet (244m) per minute

in return trunk ducts. Velocity in branches should not exceed
800 feet (244m) per minute supply and 600 feet (183m) per

minute in the return.

Ductwork installed outdoors should have a minimum of 2"

(50.8mm) of fiberglass insulation and a weatherproof vapor

barrier. It should also be protected against damage. Caulk
and flashing, or other means adequate to provide a perma-

nent weather seal should be used.

Ductwork installed in attics or other areas exposed to out-
side temperatures should be installed with a minimum of 2"

(50.8mm) fiberglass insulation and have an indoor type va-

por barrier.
The use of flexible, non-combustible connectors between

main trunk ducts and supply and return air plenums is rec-
ommended to minimize vibration transmission.

NOTE: Connect supply and return air plenums to unit in a

manner that will allow the top of the unit to be removed with-
out removing plenums. Plenums MUST be individually

sealed to unit casing.

Filters

CAUTION

Do NOT operate the unit without all filters in place.
All air MUST pass through a filter before entering the unit.

Electronic air cleaner, optional filter racks, or other accessi-

ble filter arrangements MUST be installed in the return air
ductwork.

NOTE: Ifthe unit has an economizer or any other type of out-
door air damper, disposable filters MUST be used in the in-

ternal filter racks.

For replacement filter sizes and instructions, see Air Filters.

Circulating Blower

DeterminingPulleyTurns

1. From the system design, determine the external static
pressure (ESP) for the supply ducts, return ducts and
registers, diffusers, grilles, dampers, heaters and spe-

cial filters (if any).

2. If unit isto be set up in cooling mode, add .08" W.C. (20
Pa) for wet coil operation to the total ESP determined
in Step 1.

3. From the system design, determine the desired airflow
in CFM (L/s).

4. To determine the pulley turns necessary to obtain the

desired CFM (L/s), go to the Circulating Blower Perfor-

mance Data graph for the unit.

Personal injury hazard.

Use extreme care during the following proce-

dures and obey Safety Information.

Failure to do so may result in personal injury.

I

The following safety rules MUST always be followed when
working near belt drive.

Always Turn The Power Off

Turn the power to the unit OFF before you begin work-

ing on it.

Always Wear Protective Clothing

NEVER wear loose or bulky clothes, such as neckties,

exposed shirttails, loose sleeves, or lab coats around

belt drives. Wear gloves while inspecting sheaves to

avoid nicks, burrs, or sharply worn pulley edges.

The blower speed is changed by adjusting the variable
speed pulley mounted on the blower motor.

Ifthe blower speed needed is different than the speed of the
blower as shipped, follow the steps below to change the I

blower speed. Before changing the blower speed, read the

I

above safety rules first.

5. Turn electric power OFF.

6. Remove the side blower access panel (see Figure 1
on Page 4)

10. Loosen set screw(s) on the outer half of the adjustable
pulley.

7. Economizer

The purpose of an economizer is to: economizers or on the actuator motor of three-position

economizers.

• Provide cool outside air to the conditioned space dur-
ing the cooling cycle to minimize the use of the com-

pressors.

• Bring outside air into the conditioned space to meet
minimum fresh air requirements whenever the circula-

tion blower is running.

Figure 16 Downflow Economizer 1

Theoryof Operation

The economizer has two sets of dampers that are mechani-
cally linked together. The fresh air dampers regulate the in-

take of outside air and the return air dampers regulate the
flow of return air (see Figure 16). When the fresh air damp-

ers modulate open, the linkage causes the return air damp-
ers to modulate closed.

The economizer is controlled by a logic module which field
connects to the unit controls through a plug harness. The

logic module also controls the compressor staging based on

the thermostat input.
The minimum opening position of the fresh air dampers is

field adjustable. It is set on the logic module of modulating

The enthalpy sensor is factory installed on the fresh air
dampers of the economizer. The enthalpy change-over

point is adjustable on the logic module.
A discharge air sensor is field installed in the blower inlet.

The discharge air sensor keeps the discharge air above
56°F (13.3°O).

A positive pressure is created when the fresh air dampers
open and the return dampers close. This pressure must be

vented or the air will not circulate properly. This is the func-
tion of the barometric relief damper. A positive pressure

forces thebarometric relief damper to swing open.
The fresh air dampers open to the minimum position for out-

side air whenever the circulation blower is ON.
When the thermostat is in the FAN AUTO position, the fresh

air dampers will close completely whenever heating or cool-
ing is not called for.

If Using a2- StageThermostat

On a call for cooling, ifthe economizer outdoor air sensor de-
termines that the outside air is cool enough (and in the case

of an enthalpy sensor, dry enough), the fresh air dampers
will modulate open and the return air dampers will modulate

closed.

If the conditioned space is not being maintained at the se-

lected temperature, the thermostat will make Y2 and call for
second stage cooling by energizing the economizer logic

module at the low voltage terminal board. This energizes Y1
and contactor which energizes the condenser fan and com-

pressor for cooling to assist the economizer.

NOTE FOR 6-1/3 UNITS ONLY: Contactor C2 cannot be
energized to operate compressor 2 while the economizer is
still energized since Circuit 1 is activating the economizer

and Circuit 2 is activating compressor 1.

If the thermostat is still calling for cooling and the outside air
warms to above the setting for economizer operation:

A. The economizer dampers will close to the minimum

position for outside air and remain there.

B. Contactor Cl will remain energized and compressor 1

will continue to run.

C. Conctactor C2 will close and compressor 2 will start.

If Using a Single- Stage Thermostat

When using a single stage thermostat, all steps as outlined
above will be followed with the exception of the following:

The compressor will only be energized when the outside air
reaches a temperature above the preset limit of the econo-

mizer. When ambient conditions are NOT suitable for econo-
mizer operation, ONLY the compressor will run, and the
economizer will NOT be energized.

tion and be damaged. It is therefore necessary to check for
proper rotation.

CAUTION

Electrical shock, fire and/or explosion hazard.

Use extreme care during all of the following

checks and procedures.

Make sure Electric Power and is turned OFF as

instructed in appropriate steps.

Failure to follow this warning can result in prop-

erty damage, personal injury, and/or death.

Check the unit's operation as outlined in the following
instructions.

Blower and Phasing Check

1. Shut OFF electric power at unit disconnect.

2. Check to see that clean, properly sized air filters are
installed.

3. Check to see that everything inside the unit is clear and
ready to operate safely. Ensure that there are no ob-

jects in, on or around the motor, belt or blower wheel.

Do NOT operate the unit with the compressor(s) run-

ning until proper blower rotation has been confirmed by
running the following test.

7. Set thermostat fan switch to ON. The circulating air
blower should come ON.

.

Shut OFF electric power at unit disconnect and visual-
ly observe the direction of the blower rotation as it

slows down. Do NOT put hands or any other object in,
on or around the belt, motor or blower wheel. If blower

wheel rotation is the same as the directional arrow on
the blower housing, proceed to the next step.

CAUTION

If blower rotation is incorrect, shut electric power OFF at
unit disconnect and reverse any two supply wires at

field connections ONLY. Do NOT reverse the blower
and/or compressor leads or rewire any internal wiring.

After rewiring is done, repeat blower rotation check to
ensure that blower rotation is now correct.

9. If blower rotation iscorrect, reset thermostat fan switch
to AUTO.The circulating air blower should go OFF.

Nothing should be running.

10. Shut OFF electric power at unit disconnect.

4. Set thermostat Heat-Cool selector to OFF.

5. Set thermostat fan switch to AUTO.

Moving parts hazard.

Do NOT put hands or any other object in, on or

around the motor, belt or blower wheel. Ensure
that there are no objects in, on or around the mo-
tor, belt or blower wheel before turning electric

power on.

Failure to follow this warning can result in prop-

erty damage, personal injury, and/or death.

,

Turn ON electric power. Nothing should start running.

If any unusual arcing, odors or noises are encoun-

tered, shut OFF electric power immediately and check
for wiring errors.

NOTE: The circulation blower motor and compressor(s) are

three phase and are factory synchronized for proper rota-
tion. Even if the circulation blower motor comes on and air

seems to be circulating, it is possible that the blower motor
rotation isincorrect due to improperphasmg. The scroll com-

pressor(s) (if equipped) will run backwards under this condi-

Cooling Checks

The compressors have afive minute anti-cycle delay that is
activated whenever the compressors turn off. For instance, if

the unit is manually shut off when the compressors are run-
ning and the unit is turned back ontwo minutes later, it will be

an additional three minutes before the compressors will re-
start.

CAUTION

Do NOT operate the unit with the compressor(s) run-
ning until proper blower rotation has been confirmed
during the Blower and Phasing Check in the previous
section. If the phasing is incorrect, the scroll compres-

sor(s) (if equipped) will run backwards and they will be
damaged.

1. Be sure that electric power is OFF.

2. To check cooling Stage 1, place jumper wires across
low voltage terminal board terminals R to G, R to Y1.

3. Turn electric power ON. Check to see that the follow-
ing occurs:

Adjusting Room Temperatures

If the temperature in individual rooms is not as desired, bal-

ance the system by adjusting the dampers in the branch
ducts (see Figure 16). Adjust a little at a time and wait a day

after each change to judge the effect. Once the dampers are
adjusted for normal weather conditions, it is best to leave

them that way. Compensate for temporary weather changes

by adjusting the thermostat setting.
