Piping Recommendations
• Trap each steam coil individually. Always keep the trap clean
and in good working condition.
• When tumble dryer is on the end of a line of equipment, ex-
tend header at least 4 feet [1.2 m] beyond tumble dryer. Install
shut-off valve, union, check valve and bypass trap at end of
line. If gravity return to boiler, omit trap.
• Insulate steam supply and return lines for safety of operator
and safety while servicing tumble dryer.
WARNING
All system components must have a 125 psig [8.6
bar] working pressure. Shut-off valves must be in-
stalled upstream of the steam solenoid valve and
downstream of each steam trap so components can
be isolated for maintenance or emergency purposes.
All components (solenoid valve, traps) must be sup-
ported to minimize loads on the tumbler steam coil
connections.
W701
Installing Steam Trap and Making Con-
densate Return Connections
The steam trap must be installed and the coil outlet connections
must be connected to the condensate return lines. The following
steps outline the procedure for installing the steam trap and con-
necting the condensate return lines. Refer to
Figure 29
for typical
installations.
1.
Use flexible lines between steam inlet solenoid and steam
coils, as well as outlet between steam coil and traps.
2.
If necessary, install a strainer at the end of each flexible hose.
3.
Install a steam trap to each strainer.
IMPORTANT: Steam trap must be installed a mini-
mum of 18 inches [457 mm] below the steam coil
outlet connections.
4.
Install a shut-off valve to each steam trap.
5.
Connect to the condensate return lines.
6.
For steam solenoid valve wiring connections, refer to Wiring
Diagram supplied with tumble dryer.
Thermal Oil Prep
It is the responsibility of the customer to install appropriate coil
and heating system for thermal oil prep models. The manufactur-
er is not responsible for the performance or safety of the custom-
er installed thermal oil system. To ensure proper operation, refer
to the Specifications and Dimensions section for the Btu input of
equivalent steam models. Thermal oil systems that do not deliver
appropriate Btus will dry slower. For solenoid valve wiring con-
nections, refer to the Wiring Diagram supplied with tumble dryer.
