Parker Sporlan SD-114 Installation And Servicing Instructions

3-Way Valves
INSTALLATION AND SERVICING INSTRUCTIONS
SD-114 / 122013
GENERAL INFORMATION
Installation Precautions
1. Do not attempt installation of the valve before
pumping the entire system down. Make abso-
lutely certain system pressure is no more than 2
or 3 psi above atmospheric pressure.
2. The solenoid coil must not be energized unless it
is installed on the valve. To do so would cause
coil to overheat and burn out.
3. The solenoid coil should be fused in accordance
with local codes.
4. If a service valve is installed ahead of a solenoid
valve, it should be closed during service proce-
dures. Do not use a solenoid valve as a safety
shutoff while making repairs to the system.
Be sure there is no liquid in the line between
the service and solenoid valves when they
are in the closed position that could create
dangerous hydraulic pressures.
5. Do not twist the valve assembly by pulling or
pushing on the enclosing tube or coil assembly.
6. Do not carry a coil assembly or complete valve
by the coil leads. This could damage the coil and
cause a coil burnout. Do not carry the valve by
the pilot tube. This could cause damage to the
flare (SAE) joint, creating an external leak.
7. Electrically ground the valve body. Typically
this is done through the fluid piping or the elec-
trical conduit.
8. Before energizing the valve, verify that the sup-
ply voltage and frequency matches the solenoid
coil marking.
Soldering Precautions
Solder connections on Sporlan Heat Reclaim Valves
are copper. Any of the commonly used types of sol-
der are satisfactory with these materials. Regardless
of the type of solder used, it is important to avoid
over-heating the valve. Extreme care should be
taken when brazing connections to avoid dam-
age to internal synthetic parts. The torch tip
should be large enough to avoid prolonged heating
of the connection during the brazing operation.
Overheating can also be minimized by directing
the flame away from the valve body. As an extra
precaution, a wet cloth may be wrapped around the
body. Cool body thoroughly after making each
connection. As an extra precaution, a wet cloth
may be wrapped around the body during the
soldering operation.
CAUTION: When installing 1/4" flare pilot line
connections, flare body MUST be supported with
another wrench. On the B5D valve, the pilot valve
body MUST be supported when tightening the 1/4"
flare connection. Failure to do either of the above
may cause leaks or valve damage.
Wiring
Check the electrical specifications of the coil to be
sure that they correspond to the available electrical
service. See page 4 for typical wiring schematics for
single compressor systems.
The 1/2" BX conduit connection of junction box
on the coil of Heat Reclaim Valves may be rotated
to any position by loosening the coil screw. Valves
with four-wire dual voltage coil have a wiring dia-
gram decal (see diagram below) on the coil housing
or bracket. This illustrates which wires to connect
for either 120, 208, or 240 volt operation. Wiring
and fusing (when used) must comply with prevail-
ing local and national wiring codes and ordinanc es.

(S)8D-SC, (S)12D-SC, (S)16D-SC, 10G
The parts kit for the 3-Way Heat Reclaim Valves
includes the piston assembly. The Bleed "B" and
Non-Bleed "C" versions of the 3-Way valves use
different pistons; therefore, different parts kits are
required.
