NOTES:
1. Factory wiring is in compliance with NEC. Any field modifications
or additions must be in compliance with all applicable codes. Use
copper, copper-clad aluminum for field power supply only.
2. Field power supply wiring must be 75 C minimum.
3. Compressor thermally protected. Three-phase motors are pro-
tected against primary single-phasing condition.
4. Pilot duty control must be field supplied. Minimum contact rating
must be 25 va.
5. 60 Hz units have 120-volt control circuit. 50 Hz units have
230-volt control circuit. A separate source of supply at the correct
voltage must be field supplied through a fused disconnect device
with a maximum rating of 15 A to TB2 connections
(Hot Side) and
(Neutral).
6. Open control circuit disconnect switch for servicing only. Discon-
nect must remain closed for crankcase heater to operate.
7. A transformer of the following rating may be field supplied for
60 Hz units: 350 va.
8. Transformer must be fused and grounded per applicable codes.
9. If any of the original wiring furnished must be replaced, it must
be replaced with 90 C wire or its equivalent.
