USING MANIFOLD GAUGE SET
When checking
"the
system charge, only use a manifold
gauge set that features low loss anti-blow back fillings.
Manifold gauge set used with
HFC-410A
refrigerant
systems must
be
capable
of
handling the higher system
operating pressures. The gauges should be rated for use
With
pressures
of
0 - 800 psig on the high side and a
loW
side
of
3D"
vacuum
to
250
psig with dampened speed to
500
psi. Gauge hoses
must
be rated for use at up to
800
psig of pressure with a
4000
psig burst rating.
OPERATING
SERVICE
VALVES
The liquid and vapor line service valves are
lJsed
for
removing refrigerant, flushing, leak testing, evacuating,
checking charge and charging,
Each valve is equipped with a service port which has
