electric heat options, etc.) that interface with
the heat pump should be functionally checked
to verify system operation and compatibility with
the heat pump. Refer to the installation instruc-

UNIT MAINTENANCE
WARNING:
To avoid risk of electrical shock, personal
injury, or death, disconnect all electrical
power to the unit before performing any
maintenance or service. The unit may
have more than one electrical supply.
Refrigerant Charging —
Packaged heat pumps
are fully charged at the factory. The system
refrigerant charge can be checked and adjusted
through the service ports provided behind the
front panel. Use only gauge lines which have a
“Schrader” depression device present to actuate
the valve. Draw a vacuum on gauge lines to
remove air before attaching them to the service
ports on the unit. Refrigerant charging must be
done by qualifi ed personnel familiar with safe
and environmentally responsible refrigerant
handling procedures.
WARNING:
Single Packaged Heat Pumps are
shipped fully charged and ready for
installation. When a system is installed
according to these instructions, no
refrigerant charging is required. If repairs
make it necessary for evacuation and
charging, it should only be done by
qualifi ed, trained personnel thoroughly
familiar with this equipment. Some local
codes require licensed installation/
service personnel to service this type
of equipment. Under no circumstances
should the owner attempt to install and/
or service this equipment. Failure to
comply with this warning could result
in property damage, personal injury,
or death.
CAUTION:
Use care when removing parts from this
unit. Personal injury can result from sharp
metal edges present in all equipment of
sheet metal construction.
Routine Maintenance —
Proper maintenance is
important to achieve optimum performance from
the heat pump. The ability to properly perform
maintenance on this equipment requires certain
mechanical skills and tools. If you do not possess
these skills, contact your dealer for maintenance.
Consult your local dealer about the availability of
maintenance contracts. At a minimum, routine
maintenance should include the following:
1. Inspect and clean or replace air fi lters at
the beginning of each heating and cooling
season, or more frequently if required.
2. Inspect the condensate drain and outdoor
coil at the beginning of each cooling season.
Remove any debris. Clean the outdoor coil
and louvers as necessary using a mild
detergent and water. Rinse thoroughly with
water.
3. Inspect the electrical connections for
tightness at the beginning of each
heating and cooling season. Service as
necessary.
CAUTION:
The unit should never be operated
without a fi lter in the return air system.
Replace disposable fi lters with the same
type and size.
4. The motors for the circulating air blower
and the outdoor fan are pre-lubricated at
the factory. No further oiling is required for
the life of this product.
