General InstructIOns
ImPOrtant
The equipment covered in this manual is to be installed by
trained, experienced service and installation technicians.
Any heat pump is more critical of proper operating
charge and an adequate duct system than a straight air
conditioning unit. All duct work, supply and return ducts,
must be properly sized for the design airow requirement
of the equipment. ACCA is an excellent guide to proper
sizing. All duct work or portions thereof not in the
conditioned space should be properly insulated in order
to both conserve energy and prevent condensation or
moisture damage.
shIPPInG DamaGe
Upon receipt of equipment, the carton should be checked
for external signs of shipping damage. If damage is
found, the receiving party must contact the last carrier
immediately, preferably in writing, requesting inspection
by the carrier’s agent.
General
The refrigerant system is completely assembled and
charged. All internal wiring is complete.
The unit is designed for use with or without duct work.
Flanges are provided for attaching the supply and return
ducts.
These instructions and any instructions packaged with any
separate equipment required to make up the entire heat
pump system should be carefully read before beginning
the installation. Note particularly “Starting Procedure”
and any tags and/or labels attached to the equipment.
While these instructions are intended as a general
recommended guide, they do not supersede any national
and/or local codes in any way. Authorities having
jurisdiction should be consulted before the installation is
made.
FIelD InstalleD heater PacKaGes
(OPtIOnal)
These packaged heat pumps are manufactured without
supplementary electric heaters. Supplementary heaters are
available for simple, fast eld installation.
A separate power circuit is required for the supplementary
heaters.
IMPORTANT: Refer to Table 1 when designing duct
work for maximum available static pressure with heater
installed.
Refer to Tables 2 and 4 for proper application information
on all available heater combinations and what units they
can be used with. It also shows the applicable circuit
ampacities, fuse size, and wire size for each heater
combination.
These instructions explain the recommended method to
install the air cooled self-contained unit and the electrical
wiring connections to the unit.
and conductor wires in accordance with the national Electrical Code and all existing local codes.
Time delay fuses of HACR type circuit breakers must be used for 60 and smaller sizes. Standard fuses or circuit breakers are suitable for sizes 70 and
larger. 480V circuit breakers are not HACR type.
Based on wire suitable for 75 degree C. Other wiring materials must be rated for marked Minimum Circuit Ampacity or greater.
NOTE: While this electrical data is presented as a guide, it is important to electrically connect properly sized fuses
