Using
a
digital
psychrometer
,
measure
the
return
air
wet-bulb
temperature
at
the
unit
just
before
the
coil.
Also
measure
the
outdoor
dry-bulb
temperat
ure.
Use
these
temperatures
to
locate
the
target
superheat
on
the
charging
table.
Do
not
attempt
to
charge
the
system
if
these
conditions
fall
outside
of
this
charging
table.
ADD
refrigerant
to
DECREASE
total
superheat.
REMOVE
refrigerant
to
INCREASE
total
superheat.
Always
allow
10
to
15
minutes
of
operation
after
any
refrigerant
or
air
flow
change
prior
to
determining
the
final
superheat.
