1. Symbols are electrical representation only.
2. Compressor and fan motor furnished with
inherent thermal protection.
3. To be wired in accordance with National Electric
N.E.C. and local codes.
4. N.E.C. class 2, 24 V circuit, min. 40 VA required,
60 VA on units installed with lls.
5. Use copper conductors only.
6. Typical cooling only thermostat, for other
arrangements see installation instructions.
7. If indoor section has a transformer with a
grounded secondary, connect the grounded side
to the BRN lead.
8. When start relay and start capacitor are installed,
start thermistor is not used.
9. CH not used on all units.
10. If any of the original wire, as supplied must be
replaced, use the same or equivalent wire.
11. Check all electrical connections inside control box
for tightness.
12. Do not attempt to operate unit until service valves
have been opened.
13. Do not rapid cycle compressor. Compressor must
be off 3 minutes to allow pressures to equalize
between high and low side before starting.
14. Wire not present if HPS, LPS, DTS or CTD are
used.
CAUTION
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 5 °F 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. Carefully relieve refrigerant pressure within this
unit before final disposal.
