NOTICE
Roof Damage!
This system contains both refrigerant and oil.
Some rubber roofing material may absorb oil,
causing the rubber to swell. Bubbles in the rubber
roofing material can cause leaks. Protect the roof
surface to avoid exposure to refrigerant and oil
during service and installation. Failure to follow
this notice could result in damage to roof surface.
Use of this unit as a construction heater or air conditioner
is not recommended during any phase of construction.
Very low return air temperatures, harmful vapors and
operation of the unit with clogged or misplaced filters will
damage the unit.
If this unit has been used for heating or cooling of
buildings or structures under construction, the following
conditions must be met or the warranty will be void:
The vent hood must be installed per these installation
instructions.
A room thermostat must control the unit. The use of
fixed jumpers that will provide continuous heating or
cooling is not allowed.
A pre-filter must be installed at the entry to the return

In downflow discharge installations, install the unit on a
non-combustible surface only. Unit may be installed on
combustible surfaces when used in horizontal discharge
applications or in downflow discharge applications when
installed on an LARMF18/36 roof mounting frame.
NOTE - Securely fasten roof frame to roof per local codes.
CAUTION
To reduce the likelihood of supply / return air by
pass and promote a proper seal with the RTU, duct
work / duct drops / diffuser assemblies must be
supported independently to the building structure.
A-Downflow Discharge Application
Roof Mounting with LARMF18/36
1- The LARMF roof mounting frame must be installed,
flashed and sealed in accordance with the
instructions provided with the frame.
2- The LARMF roof mounting frame should be square
and level to 1/16” per linear foot (5mm per linear
meter) in any direction.
3- Duct must be attached to the roof mounting frame
and not to the unit; supply and return plenums must
be installed before setting the unit.
Installer's Roof Mounting Frame
Many types of roof frames can be used to install the unit
depending upon different roof structures. Items to keep
in mind when using the building frame or supports are:
1- The base is fully enclosed and insulated, so an
enclosed frame is not required.
2- The frames or supports must be constructed with
non-combustible materials and should be square and
level to 1/16” per linear foot (5mm per linear meter)
in any direction.
3- Frame or supports must be high enough to prevent
any form of moisture from entering unit.
Recommended minimum frame height is 14”
(356mm).
4- Duct must be attached to the roof mounting frame
and not to the unit. Supply and return plenums must
be installed before setting the unit.
IMPORTANT
The Clean Air Act of 1990 bans the intentional vent
ing of refrigerant (CFC's and HCFC's) as of July 1,
1992. Approved methods of recovery, recycling or
reclaiming must be followed. Fines and/or incar
ceration may be levied for non-compliance.
5- Units require support along all four sides of unit base.
Supports must be constructed of steel or suitably
treated wood materials.
NOTE-When installing a unit on a combustible surface for
downflow discharge applications, an LARMF18/36 roof
mounting frame is required.
Page 7
507124-04 3/2016
B-Horizontal Discharge Applications
1- Units installed in horizontal airflow applications must
use an LARMFH18/24 horizontal roof mounting
frame. The supply air duct connects to the horizontal
supply air opening on the LARMFH18/24. The return
air duct connects to the unit horizontal return air
opening. Refer to unit dimensions.
2- Specified installation clearances must be maintained
when installing units. Refer to figure 1.
3- Top of support slab should be approximately 4”
(102mm) above the finished grade and located so no
run-off water from higher ground can collect around
the unit.
4- Units require support along all four sides of unit base.
Supports must be constructed of steel or suitably
treated wood materials.
Duct Connection
All exterior ducts, joints and openings in roof or building
walls must be insulated and weather-proofed with

Connect Gas Piping
Before connecting piping, check with gas company or
authorities having jurisdiction for local code
requirements. When installing gas supply piping, length
of run from gas meter must be considered in determining
pipe size for 0.5” w.c. (.12kPa) maximum pressure drop.
Do not use supply pipe smaller than unit gas connection.
For natural gas units, operating pressure at the unit gas
connection must be a minimum of 4.7” w.c. (1.17kPa)
and a maximum of 10.5” (2.60kPa) w.c. For LP/propane
gas units, operating pressure at the unit gas connection
must be a minimum of 11” w.c. (2.74kPa) and a maximum
of 13.5” w.c. (3.36kPa).
When making piping connections a drip leg should be
installed on vertical pipe runs to serve as a trap for
sediment or condensate. A 1/8” N.P.T. plugged tap is
located on gas valve for test gauge connection. Refer to
Heating Start-Up section for tap location. Install a ground
joint union between the gas control manifold and the
main manual shut-off valve. See figure 4 for gas supply

Blower Operation and Adjustments
B-Blower Access
Supply Air Inverter Units - The blower rotation will
always be correct on units equipped with an inverter.
Checking blower rotation is not a valid method of
determining voltage phasing for incoming power.
Supply Air Inverter Units and Units Equipped With
Optional Voltage or Phase Detection - The Unit
Controller checks the incoming power during start-up. If
the voltage or phase is incorrect, the Unit Controller will
display an alarm and the unit will not start.
IMPORTANT
Three Phase Scroll Compressor Voltage Phasing
Three phase scroll compressors must be phased se
quentially to ensure correct compressor and blower*
rotation and operation. Compressor and blower are
wired in phase at the factory. Power wires are colorcoded as follows: line 1-red, line 2-yellow, line 3-blue.
1-Observe suction and discharge pressures and blow
er* rotation on unit start-up.
2-Suction pressure must drop, discharge pressure must
rise and blower* rotation must match rotation marking.
If pressure differential is not observed or blower* rota
tion is not correct:
3-Disconnect all remote electrical power supplies.
4-Reverse any two field-installed wires connected to
the line side of S48 disconnect or TB13 terminal strip.
Do not reverse wires at blower contactor.
5-Make sure the connections are tight.
Discharge and suction pressures should operate at
their normal start‐up ranges.
*Supply air inverter blower motors should rotate in the
correct direction; verify scroll compressor rotation
separately. Contact technical support if the blower is
rotating incorrectly.
1- Disconnect jack/plug connector to blower motor. Also
disconnect jack/plug connector heating limit switches
on gas units.
2- Remove screws on either side of blower assembly
sliding base. See figure 13.
3- Pull base toward outside of unit.
C-Determining Unit CFM
IMPORTANT - Supply air inverter units are factory-set
to run the blower at full speed when there is a blower (G)
demand without a heating or cooling demand. Refer to
the field-provided, design specified CFM for all modes
of operation. Use the following procedure to adjust
motor pulley to deliver the highest CFM called for in the
design spec. See Inverter Start-Up section to set blower
CFM for all modes once the motor pulley is set.
1- The following measurements must be made with a
dry indoor coil. Run blower (G demand) without a
cooling demand. Measure the indoor blower shaft
RPM. Air filters must be in place when measurements
are taken.
2- With all access panels in place, measure static
pressure external to unit (from supply to return).
Blower performance data is based on static pressure
readings taken in locations shown in figure 14.
Note - Static pressure readings can vary if not taken
where shown.
3- Referring to page 17, use static pressure and RPM
readings to determine unit CFM. Use page 18 when
installing units with any of the optional accessories
listed.
A-Blower Operation
Initiate blower only (G) demand at thermostat according
to instructions provided with thermostat. Unit will cycle on
thermostat demand. The following steps apply to
applications using a typical electro-mechanical
thermostat.
1- Blower operation is manually set at the thermostat
subbase fan switch. With fan switch in ON position,
blowers will operate continuously.
2- With fan switch in AUTO position, the blowers will
cycle with demand. Blowers and entire unit will be off
when system switch is in OFF position.
4- The blower RPM can be adjusted at the motor pulley.
Loosen Allen screw and turn adjustable pulley
clockwise to increase CFM. Turn counterclockwise to
decrease CFM. See figure 13. Do not exceed
minimum and maximum number of pulley turns as
shown in table 2.

D-Blower Belt Adjustment
Maximum life and wear can be obtained from belts only if
proper pulley alignment and belt tension are maintained.
Tension new belts after a 24-48 hour period of operation.
This will allow belt to stretch and seat into pulley grooves.
Make sure blower and motor pulley are aligned. See figure
15 for blowers not equipped with a tensioner and figure 16
for units equipped with an optional belt tensioner.
Blowers Without Belt Tensioner
1- Loosen four screws securing blower motor to sliding
base. See figure 13.
LGH/LCH156, 180, 210, 240, 300S
FIGURE 14
2- To increase belt tension -
Turn belt tension adjusting screw to the left, or
counterclockwise, to tighten the belt. This increases
the distance between the blower motor and the
blower housing.
To loosen belt tension -
Turn the adjusting screw to the right, or clockwise to
loosen belt tension.
3- Tighten four screws securing blower motor to sliding
base once adjustments have been made.

1- Loosen the bolt in the center of the tensioner. See
figure 17.
2- Place belt over all three pulleys.
3- Using a 15/16” wrench, turn the tensioner nut until
marks align as shown in figure 17.
4- Hold the tensioner with marks aligned and tighten the
bolt to 23 ft.lbs. using the 9/16” wrench.
E-Check Belt Tension
Overtensioning belts shortens belt and bearing life.
Check belt tension as follows:
1- Measure span length X. See figure 18.
3- Measure belt deflection force. For a used belt, the
deflection force should be 5 lbs. (35kPa) . A new belt
deflection force should be 7 lbs. (48kPa).
A force below these values indicates and
undertensioned belt. A force above these values
indicates an overtensioned belt.
MEASURE BELT TENSION
FORCE
2- Apply perpendicular force to center of span (X) with
enough pressure to deflect belt 1/64” for every inch
of span length or 1.5mm per 100mm of span length.
Example: Deflection distance of a 40” span would be
40/64” or 5/8”.
Example: Deflection distance of a 400mm span
would be 6mm.

NOTE - Using total air volume and system static pressure requirements determine from blower performance tables rpm and motor output required. Maximum usable
output of motors furnished are shown. In Canada, nominal motor output is also maximum usable motor output. If motors of comparable output are used, be sure to keep
within the service factor limitations outlined on the motor nameplate.
NOTE – Units equipped with an inverter are limited to a motor service factor of 1.0.
