Piping Recommendations; Installing Steam Trap And Making Condensate Return Connections - ALLIANCE BA120E Installation Manual

Steam Requirements
Steam Pressure PSI [ bar]
80-100 [5.3-6.9]
* Based on 6.9 bar.

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.
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 tumble dryer steam
coil connections.
Installing Steam Trap and Making
Condensate 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 16 and Fig-
ure 17 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 [460 mm] recommended below
the steam coil outlet connections.
4. Install a shut-off valve to each steam trap.
5. Connect to the condensate return lines.
