A. IMPORTANT SAFETY AND GENERAL INFORMATION
A.1 Introduction
This booklet contains the installation and operating
instructions for your 7.5 ton, 8.5 ton, 10 ton, or 12.5
ton combination gas heating/electric cooling unit.
There are some precautions that should be taken
to ensure proper operation. Improper installation
can result in unsatisfactory operation or dangerous
conditions.
Read this booklet and any instructions packaged
with separate equipment required to make up the
system prior to installation. Give this booklet to the
owner and explain its provisions. The owner should
retain this booklet for future reference.
WARNING: The manufacturer’s warranty
does not cover any damage or defect to the air
conditioner caused by the attachment or use of any
components, accessories or devices (other than
those authorized by the manufacturer) into, onto or
in conjunction with the air conditioner.
You should be aware that the use of unauthorized
components, accessories or devices may adversely
affect the operation of the air conditioner and may
also endanger life and property. The manufacturer
disclaims any responsibility for such loss or
injury resulting from the use of such unauthorized
components, accessories or devices.
A.2 Agency Performance Audit
and Efciency Testing Notice
NOTICE: BREAK-IN PERIOD
Prior to agency testing, run the compressor for
16 hours at 115of outdoor ambient temperature
and 80odry bulb / 75owet bulb indoor ambient
temperature.
NOTICE: EFFICIENCY TESTING NOTICE
For purposes of verifying or testing efciency
ratings, the test procedure in title 10 Appendix
M to Subpart B of Part 430 (Uniform Test
Method for Measuring the Energy Consumption
of Central Air Conditioners and Heat Pumps)
and the clarifying provisions provided in the
standards listed below that were applicable at
the date of manufacture should be used for test
set up and performance.
SETUP
• ASHRAE 37 - 2009 (RA 2019)
PERFORMANCE:
• ANSI/ASHRAE 90.1:
o 2013 for ZT models and some ZS models
o 2007 for ZR models and some ZS models
• ANSI/ASHRAE 103 (2017)
• AHRI Operations for Unitary Large AC
Equipment 340/360 (2015)
• CSA Z21.47 (2016)
SAFETY
UL 1995 5th Edition
CSA Z21.47 (2016)
A.3. Importance of a Quality
Installation
Optimal system performance and longevity
depend upon a quality and proper installation.
Failure to properly setup and commission this
unit could result in undesirable operation and
subsequent faults and potential failures.
Carefully follow all guidelines listed in the manual
and industry best practices. Conform to all local
code requirements. Contact your local technical
representative with any questions or concerns.
A.4. Importance of Air Flow
and Setup
Optimal system performance is also dependent
upon having the ideal airow across the
condensing and evaporating coils, and upon
matching the charge weight to the manufacturer’s
spec for the unit. Improper or restricted air
ow, and incorrect charge weight, will hinder
the performance of the unit. Please refer to the
manufacturer’s recommended clearances for
setting the unit and the included guide for setting
air ow. Refer to the rating plate for the charge
weight.
A.5. Checking Product and
Inspection
Upon receiving the unit, inspect it for any
damage from shipment. Claims for damage,
either shipping or concealed, should be led
immediately with the shipping company.
IMPORTANT: Check the unit model number,
heating size, electrical characteristics, and
accessories to determine if they are correct.

B.1 Safety Warnings
B. GENERAL SPECIFICATIONS
WARNING: Use only with type of gas
approved for this unit. Refer to the unit rating plate.
WARNING: Install this unit only in a
location and position as specied in the location
requirements and considerations section of these
instructions. Provide adequate combustion and
ventilation air to the unit space as specied in the
venting section of these instructions.
WARNING: Provide adequate combustion
and ventilation air to the unit space as specied in
the combustion and ventilation air section of these
instructions.
WARNING: Combustion products must be
discharged outdoors. Refer to local building codes
for ducting combustion exhaust.
WARNING: Never test for gas leaks with
an open ame. Use a commercially available soap
solution made specically for the detection of leaks
to check all connections, as specied in gas supply
and piping section of these instructions.
WARNING: Always install unit to operate
within the unit’s intended temperature-rise range
with a duct system which has an external static
pressure within the allowable range, as specied in
ducting section of these instructions. See also unit
rating plate.
WARNING: When a unit is installed so
that supply ducts carry air circulated by the unit
to areas outside the space containing the unit, the
return air shall also be handled by duct(s) sealed to
the unit casing and terminating outside the space
containing the unit.
WARNING: This unit may be used to
heat the building or structure during construction
if the following installation requirements are
met. Installation must comply with all installation
instructions including:
• Furnace operating under thermostatic control;
• Return air duct sealed to the furnace;
• Air lters in place;
• Set furnace input rate and temperature rise per
rating plate marking;
• Return air temperature maintained between 55°f
(13°c) and 80°f (27°c);
• Clean furnace, duct work and components upon
substantial completion of the construction process,
and verify furnace operating conditions including
ignition input rate, temperature rise and venting,
according to the instructions.
