Wiring
Wiring the HPSV 10020/604
1. Disconnect all power to the leads before wiring to prevent
electrical shock and equipment damage.
2. Run pigtails through conduit to a splice box.
3. Connect pigtails acc. to "Electrical Connection".
4. The conduit shall be suitable for 24 VDC and capable of
at least 2 A and rated for at least 75 ˚C (167 ˚F).
All wiring must comply with local electrical
codes and regulations.
Label all wires prior to disconnection when ser-
vicing valves. Wiring errors can cause improper
and dangerous operation. Verify proper operation
after servicing.
No protection elements (diode, fuse, VDR)
are implemented in the valve. No rectifier or
polarization diodes are applied. There is a direct
connection to the solenoid windings. Therefore, the
coil is not polarity sensitive.
Painting Valve
• It is not recommended that this valve be painted. Painting
covers date codes and other labels that identify this valve.
• If the valve needs to be painted, a paint free of volitile organic
compounds (VOC's) must be used. VOC's can damage
valve o-rings, resulting in external gas leakage over time.
Protection from Radiant Heat
• Radiant heat must be considered as a heat source that
could result in an ambient temperature higher than the
rating of this valve.
Electrical Connection
18" Pigtails with 1/2" NPT conduit
Connections are not polarity sensitive.

Note: When installed in hazardous locations, the wiring
shall be Ex ia, Ex ib, Ex ic, or Nonincendive field wiring,
as defined under the Canadian Electrical Code, C22.1
or the National Electrical Code, NFPA 70.
• During the painting process, use measures that will allow
the valve's date code and other labeling information to be
legible after the paint is dry.
• Provide propor shielding to protect against radiant heat.
