NOTE
1) MOMENTARILY SHORT PINS AND RELEASE TO BYPASS COMPRESSOR OFF DELAY.
2) SHORT FOR 5+ SEC. AND RELEASE FOR FORCED DEFROST.
3) PERMANENT SHORT WILL BE IGNORED. DEFROST WILL TERMINATE IN 30 SEC. IF
DFT OPEN. DEFROST WILL TERMINATE NORMALLY IF DFT IS XLOSED.

- NOTES -
1. Compressor damage may occur
if system is over charged.
2. This unit is factory charged with
R-22 in accordance with the
amount shown on the rating plate.
The charge is adequate for most
systems using matched coils and
tubing not over 15 feet long. The
best performance will be
achieved when the
unit operates with a suction gas
superheat at the compressor inlet
of 5ºF at normal rating
conditions of the air conditioning
and refrigeration institute (ARI).
This chart may be used to
approximate the charge if ARI
rating conditions cannot be
obtained. ARI rating conditions
are equivalent to DOE test "A"
conditions. See product data
literature for required indoor air
flow rates and for use of line
lengths over 15 ft.
3. Relieve pressure and recover all
refrigerant before system repair or
final unit disposal. Use all service
ports and open all flow-control
devices, including solenoid valves.

(LADDER FORM)
1. Compressor and fan motor furnished with inherent thermal protection.
2. To be wired in accordance with National Electric Code (N.E.C.) and local codes.
3. N.E.C. class 2, 24 V circuit, min. 40 VA required.
4. Use copper conductors only, from disconect to unit.
5. Must use thermostat and sub-base as stated in pre-sale literature.
6. If indoor section has a transformer with a grounded secondary, connect the
grounded side to "C" on the circuit board.
7. If any of the original wire, as supplied, must be replaced, use the same or
equivalent wire.
8. Check all electrical connections inside control box for tightness.
9. Do not attempt to operate unit until service valves have been opened.
10. When LPS and HPS are not required, a jumper will be installed between
Y and T1 on the defrost board.
11. Use conductors suitable for at least 75ºC (167ºF).
