SAFETY CONSIDERATIONS
Improper installation, adjustment, alteration, service,
maintenance, or use can cause explosion, fire, electrical shock or
other conditions which may cause personal injury or property
damage. Consult a qualified installer, service agency, or your
distributor or branch for information or assistance. The qualified
installer or agency must use factory-authorized kits or accessories
when modifying this product. Refer to the individual instructions
packaged with the kits or accessories when installing.
Follow all safety codes. Wear safety glasses and work gloves. Use
quenching cloths for brazing operations and have a fire
extinguisher available. Read these instructions thoroughly and
follow all warnings or cautions attached to the unit. Consult local
building codes and appropriate national electrical codes (in
U.S.A., ANSI/NFPA70, National Electrical Code (NEC); in
Canada, CSA C22.1) for special requirements.
It is important to recognize safety information. This is the safety-
alert symbol . When you see this symbol on the unit and in
instructions or manuals, be alert to the potential for personal
injury.
Understand the signal words DANGER, WARNING, CAUTION,
and NOTE. These words are used with the safety-alert symbol.
DANGER identifies the most serious hazards which will result in
severe personal injury or death. WARNING signifies hazards
which could result in personal injury or death. CAUTION is used
to identify unsafe practices, which may result in minor personal
injury or product and property damage. NOTE is used to highlight
suggestions which will result in enhanced installation, reliability,
or operation.
CAUTION
CONFIGURATION OVERRIDE HAZARD
Do not use start-up assistant or first start assistant on this VFD
application! Use of the assistant will override the factory VFD
configurations!

GENERAL
Variable Frequency Drive (VFD) Option 
2-Speed Indoor Fan Motor System
The 2-Speed Indoor Fan system utilizes a Fan Speed control board
and Variable Frequency Drive (VFD) to automatically adjust the
indoor fan motor speed in sequence with the unit’s ventilation,
cooling and heating operation. Per ASHRAE 90.1-2016 and
IECC-2015 standards, during the first stage of cooling operation
the VFD option will adjust the fan motor to provide 66% of the
design airflow rate for the unit. When the call for the second stage
of cooling is required, the VFD option will allow the design air-
flow rate for the unit established (100%). During the heating
mode, the VFD Option will allow total design airflow rate (100%)
operation. During ventilation mode, the VFD option will operate
the fan motor at 66% of full speed.
Figures 1-3 show the VFDs used for the 2-Speed Indoor Fan
system.
Fig. 1 — ACH550 Variable Frequency Drive (VFD)
Identifying Factory Option
This supplement only applies to units that meet the criteria de-
tailed in Tables 1-3. If the unit does not meet that criteria, discard
this document.
NOTE: See Figures 4-9 for examples of typical Model Number
Nomenclature.
NOTE: 48/50LC units are not covered in this document; VFDs are
standard equipment on belt drive LC units. VFD instructions for
the 48/50LC series are found in the Installation Instructions for the
LC base units.

DANGER
ELECTRICAL SHOCK HAZARD
Failure to follow this warning will result in personal injury or
death.
Before performing service or maintenance operations on unit,
turn off main power switch to unit and install lock(s) and
lockout tag(s). Ensure electrical service to rooftop unit agrees
with voltage and amperage listed on the unit rating plate. Unit
may have more than one power switch.
CAUTION
PERSONAL INJURY HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care and
wear appropriate protective clothing, safety glasses and gloves
when handling parts and servicing air conditioning equipment.

with the 2-speed indoor fan system option. Increase the recom-
mended rear panel clearance to 30 inches.
40RU/40RUQ, 524J/524J*H, FAS/FHS WITH REMOTE
VFD KEYPAD
Refer to the base unit installation instructions for standard re-
quired operating and service clearances. Install the accessory re-
mote VFD keypad before positioning the 40RU/40RUQ,
524J/524J*H, FAS/FHS unit in its final operating location.
NOTE: The remote VFD keypad is a field-installed option. It is
not included as part of the factory-installed VFD option.

IMPORTANT: Do NOT change units equipped with the
VFD option to operate at less than the preset 66% minimum
Hz setting (40 Hz). For example, do not change a unit
equipped with a standard static motor to operate at less than
40 Hz (which is 66% of its 60 Hz rating).
