(3)
Always apply local electrical codes for sizing cables and fusing. In absence of local codes, the minimum cable size should always be calculated
on basis of maximum package full load x1.25.
(4)
High pressure options allow machines to operate at high pressure ratings. See machine specification data decal for pressure ratings for these
machines.
(5)
The low side refrigerant pressure is factory set at 5.38 – 5.66 barg (78 – 82 psig). It may need to be adjusted at the hot gas valve periodically due
to local ambient and seasonal changes to avoid dryer freeze–up. See section 11.4 “Routine Maintenance” for the adjustment procedure.
(6)
Evaporator superheat is factory set and should not require adjustment unless it is measured out of specification when the dryer is operating at
its nominal load, and the discharge air pressure dewpoint is high.
See “Routine Maintenance” for the adjustment procedure.
