-NOTES-

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 DTS, 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 75 C (167 F).

325635-101 REV. B

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. 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.
