GENERAL INSTRUCTIONS
IMPORTANT
The equipment covered in this manual is to be installed by
trained, experienced service and installation technicians.
All duct work, supply and return ducts, must be properly
sized for the design air flow 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 explain the recommended method to
install the air cooled self-contained unit and the electrical
wiring connections to the unit.
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.
Refer to the electrical data shown on pages 2 and 3 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.
Refer to the installation instructions packed with the heater
for details on how to insert it into the basic unit.
FIELD INSTALLED HEATER PACKAGES
(OPTIONAL)
These packaged heat pumps are manufactured without
supplementary electric heaters. Supplementary heaters
EH5PB series (to fit P1142A3, P1148A1, and P1160A1)
are available for simple, fast, field installation.
A separate field power circuit is required for the
supplementary heaters.
IMPORTANT: Refer to Table 4 and 5 when designing
duct work for maximum available
static pressure with heater installed.
