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 airflow 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.
FIELD INSTALLED HEATER PACKAGES
(OPTIONAL)
These packaged heat pumps are manufactured without
supplementary electric heaters. Supplementary heaters are
available for simple, fast field 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.
