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. Connection for typical heat pump thermostat. For other arrangements see installation instructions.6. Use copper conductors only. Use conductors suitable for at least 75°C (167°F).
7. If indoor section has a transformer with a grounded secondary, connect the grounded side to “C” on the circuit board.8. When start capacitor and relay are installed, start thermistor (PTC) 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. It is imperative to connect 3−phase field power to unit with correct phasing. The phase rotation monitor will not allow the contactor to be energized
if the phasing is not correct. If phasing is reversed, interchange any two of the three power connections on field side.

MULTIPLYING FACTORS
(Refer to pages 6−9)
† Total capacities are net (I.D. blower heat subtracted) system capacities based on 25 foot (7.6m) line set. If additional tubing length and/or indoor unit is located above outdoor unit, a slight variation in capacity may occur.
†† At TVA rating indoor condition (75 °F db, 63 °F wb), all other indoor air temperatures are at 80 ° F db If additional tubing length and/or indoor unit is located above outdoor unit, a slight variation in capacity may occur.
* System amps are total of indoor and outdoor amps.
‡ Chart data is for 80° F indoor dry bulb. For indoor db temperatures other than 80° F, measure Indoor db and Indoor CFM, and plug these into the formula below. Measure outdoor db and indoor wet bulb, apply these to the chart above, find MBh and S/T, and plug these into the formula below. (Note: if indoor db is the only thing changing, total capacity, MBh, stays the same.)
Sensible Capacity at Indoor db LOWER than 80 ° F = ( MBh x S/T ) − ( 80 − Indoor db ) x 835 x Indoor CFM1000( )
Sensible Capacity at Indoor db HIGHER than 80 ° F = ( MBh x S/T ) +( Indoor db − 80 ) x 835 x Indoor CFM
