MAXIMATOR DLE - Connecting the Drive Air; Control Air Connection; Connecting the Inlet Line and Outlet Line

Installation
25 0000000141 - 002 - EN
The gas booster is delivered without any connection screw fittings or connecting
lines. For this purpose, observe the specifications in section “Connections” and
on the general drawing. To prevent malfunctions, the cross-sections of the con-
necting lines must be designed for the corresponding volume flows.
A failure of the check valves may lead to accidents resulting in severe or fatal in-
juries.
A return flow of the fluid via the check valves must not lead to the maximum op-
erating pressure in the supply line being exceeded.
The leakage rate thresholds must be observed.
Assess the risk for the equipment in the overall risk assessment.
5.3.1 Connecting the drive air
Connect the connecting line for the drive air to the drive air port (P
L
) of the spool
valve housing. Observe the connection specifications on the general drawing.
5.3.2 Control air connection
Using a tube or a pipe, connect the control air to the control air port (X) of the gas
booster. Observe the connection specifications on the general drawing.
5.3.3 Connecting the inlet line and outlet line
Connect the inlet and outlet lines to the corresponding gas booster ports (A and
B) in an appropriate manner. Observe the connection specifications on the gen-
eral drawing.
5.3.4 Connecting a separate bleed pipe
In an appropriate manner, connect the bleed pipe to the bleed ports (Z
1
and Z
3
).
Observe the connection specifications on the general drawing.
5.3.5 Purge line connections
In an appropriate manner, connect the purge line to the purge ports (SFP). Ob-
serve the connection specifications on the general drawing.
If the piston back chamber of single-stage double-acting gas boosters are to be
filled with an adequate gas, the bleed ports on the high pressure side Z
1
and Z
3
must be routed to a common bleed line over a short distance.
5.3.6 Exhaust silencer installation
If the exhaust air connection pipe of the gas booster is not installed separately,
the enclosed exhaust air silencer must be installed at the corresponding port.
