WARNING:
Personal injury or loss of life
may occur if you do not follow
the procedures as specified.
CAUTION:
Equipment damage, or loss of
data may occur if you do not
follow the procedures as
specified.
Required Tools
• Strap wrench
• Spanner wrench
• WD-40 (or similar)
• Silicone RTV sealant
• SINX 16, 17, or 18 for respective size
• Torque wrench with 3/8" drive
Figure 1.
Prerequisites
Verify that there is a sufficient quantity of HFC227ea
in inventory to complete the entire recharge of each
cylinder.
Figure 2.
WARNING:
Although the pressure gauge may register a
“Zero” reading, caution must be used at all
times since residual pressure may still be
present.
CAUTION:
Before beginning this procedure, make sure
the Anti-Recoil Device is installed on the
cylinder.
Disassembling the Valve
1. Energize the solenoid or depress a Local
Manual Control (CPY-LMC) to ensure there is
no pressure in the cylinder. It is normal to notice
a slight pressure release. At this point, THERE
IS NO PRESSURE IN THE CYLINDER.
