T
he dual refrigerant circuits are designed to compl
y
with
A
SHRAE 90.1 Effi cienc
y
Guidelines. Each circuit operates
using HCFC R-22 as standard, and are readil
y
convertible to
HFC R-407C at an
y
point during the lifetime of the produc
t
without any component changes. This requires no removal of
e
xisting refrigerant oil, onl
y
a refrigerant change on site.
Dual refrigerant circuits are pre-charged with R22 as
standard, or with optional R407C, and factor
y
run tested. I
f
r
efrigerant R22 is specifi ed, the chiller is designed to accep
t
R407C at a later date in the fi eld
.
Each circuit consists of a factor

tested scroll compressor,
w
ith high pressure switch, low pressure switch, pressure
r
elief valve, discharge, suction, and liquid isolation valves,
a
liquid line drier, moisture indicator, externall
y
equalized
thermal valve (suitable for R22 and R407C), plus gauge
p
ort connections
