2 to 5 ton (7.0 to 17.6 kW)
CHA/CHP16, CHP20 SERIES UNITS
CHA/CHP16 and CHP20 series units in the 2 throu h 5 ton
(7.0 throu h 17.6 kW) sizes are desi ned for outdoor roofĆ
top or round level installations in li ht commercial applicaĆ
tions. Electric heat is available in several kW sizes. Models
are available in sin le or three phase power supply and can
be utilized in downflow or horizontal supply and return air.
CHA/CHP16-024/030 model units are equipped with a
reciprocatin compressor. CHA/CHP16-036/060 and
CHP20-024/060 model units are equipped with scroll
compressors. The scroll compressor offers hi h voluĆ
metric efficiency, quiet operation and the ability to start
under system load. Continuous flank contact, mainĆ
tained by centrifu al force, minimizes as leaka e and
maximizes efficiency. The motor is internally protected
from excessive current and temperature.
CHA/CHP16 and CHP20 model units are desi ned to acĆ
cept any of several different thermostat control systems
with minimum field wirin . Control options such as econĆ
omizer, warm up kit, Honeywell T7300 thermostat or
Honeywell T8600/T8611/T8621 thermostat controls
connect to the unit with jackĆplu s. When plu ed in the
controls become an inte ral part of the unit wirin . Low
volta e thermostat connections facilitate thermostat
field wirin .
Optional electric heat is field installed. Electric heat operĆ
ates in sin le or multiple sta es dependin on the kW size.
5kW throu h 25 kW sizes are available for the CHA/CHP16
and CHP20 units.
Information in this manual is for use by a qualified service
technicial only. All specifications in this manual are subject
to chan e. Procedures outlined in this manual are repesĆ
ented as a recommendation only and do not supersede or

IMPORTANT
Im ro er installation, adjustment, alteration, service
or maintenance can cause ro erty damage, ersonĆ
al injury or loss of life. Installation and service must
be erformed by a qualified installer, service agency
or the gas su lier.
WARNING
Electric shock hazard. Can cause injury
or death. Before attem ting to erform
any service or maintenance, turn the
electrical ower to unit OFF at disconĆ
nect switch(es). Unit may have multi le
ower su lies.
WARNING
Refrigerant can be harmful if it is inhaled. Refrigerant
must be used and recovered res onsibly.
Failure to follow this warning may result in ersonal
injury or death.

CAUTION
Electrostatic discharge can affect electronic
com onents. Take recautions during unit
installation and service to rotect the unit's elecĆ
tronic controls. Precautions will hel to avoid
control ex osure to electrostatic discharge by
utting the unit , the control and the technician at
the same electrostatic otential. Neutralize elecĆ
trostatic charge by touching hand and all tools on
an un ainted unit surface, such as the blower
deck, before erforming any service rocedure.
