Electrical Shock Hazard
Electrically ground condensing unit or heat pump.
Connect ground wire to ground lug.
Use copper wire for supply connection.
Correct wire gauge is shown in the chart below.
Failure to follow these instructions can result in
death or electrical shock.
Rating Plate Ampacity
Less than 15
16 - 20
21 - 30
31 - 50
NOTE: All outdoor wiring must be suitable for outdoor use. Use
copper conductors only.
All field wiring must be done in accordance with National
Electrical Code requirements, applicable requirements of UL,
or local codes, where applicable.
Electrical wiring, disconnect means and over-current
protection are to be supplied by the installer. Refer to the
rating plate for the maximum over-current protection,
minimum circuit ampacity, and operating voltage. See the
wiring diagrams in "Make Electrical Connections."
Inverted R-22 Cylinder
(Contains clean R-22 to
be used for flushing)
Existing Vapor Line
Existing Liquid Line
Excessive Weight Hazard
Use two or more people to move and install
condensing unit or heat pump.
Failure to do so can result in back or other injury.
This heat pump is shipped in one package, completely
assembled and wired. The thermostat is shipped in a separate
carton when ordered.
1. Check the heat pump rating plate to confirm specifications
are as ordered.
2. Upon receipt of equipment, carefully inspect it for possible
shipping damage. Take special care to examine the heat
pump inside the carton if the carton is damaged.
If damage is found, it should be noted on the carrier's freight bill.
Damage claims should be filed with the carrier immediately.
Claims of shortages should be filed with the seller within 5 days.
NOTE: If any damages are discovered and reported to the carrier,
do not install the heat pump because your claim may be denied.
Flush Refrigerant Lines
Refrigerant lines must be flushed by a licensed, EPA certified
refrigerant technician in accordance with established procedures.
R-410A outdoor systems are not recommended for use with
indoor systems that have used R-22 as the refrigerant.
However, if this unit is being matched with an approved line
set or indoor coil which was previously charged with R-22
refrigerant, or if it is being matched with a coil which was
manufactured before January of 1999, the R-22 coil and line
set must be flushed prior to installation.
Check the refrigerant lines for size and length. See "Connect
NOTE: The inverted R-22 cylinder must contain at least
the same amount of refrigerant as was recovered from
the existing system.
