5.1003 Low capacity, defrost outside coil or adjust charge and
retest: Verify that the outside coil is not frosted or iced. Frost reduces
the capacity of the heat pump. If the unit is not frosted, adjust the refrig-
erant charge per the manufacturer’s specification.
5.1004 High temp split, make sure strip heat is NOT on, re-
check airflow if necessary: Check amperage to the electric strip
heaters to verify they are turned off.
Accessory Head Descriptions

FCC Compliance and Advisory Statement
This device complies with Part 15 of the FCC rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class B digital device,
according to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur
in a particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encouraged to
try correct the interference by one or more of the following measures:
1. Reorient the receiving antenna.
2. Increase the separation between the equipment and receiver.
3. Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
4. Consult the dealer or an experienced radio/TV technician for help.
Shielded interface cables must be used in order to comply with emission limits.
FCC Caution: To assure continued compliance, any changes or modifications not expressly
approved by the party responsible for compliance could void the user's authority to operate this
equipment.
