NOTES FOR FIG. 55

1.If any of the original wire furnished must be replaced, it must be replaced with Type 90 C wire or its equivalent.

2.Three-phase motors are protected under primary single-phasing conditions.

3.Thermostats: HH07AT170, 172

Subbase: HH93AZ176, 177, 178 and 179

4.Set heat anticipator at .14 amp for first stage and .14 amp for second stage.

5.Use copper conductors only.

6.TRAN is wired for 230 v unit. If unit is to be run with 208 v power supply, disconnect BLK wire from 230 v tap and connect to 208 v tap (RED). Insulate end of 230 v tap.
