SV205 Installation, Operating & Maintenance Manual
Flexible and welded pipe bores etc cleaned after fabrication.
All flanges, fasteners and mountings secure.
Vehicle PTO disengaged.
Engine management system set-up correctly for the application.
Blow (ball) valve open (if starting against a tank pressure).
Commissioning/testing 1.5 - 2" gate valve and silencer fitted.
Discharge pressure gauge fitted (0-3 bar g).
Ancillaries correctly fitted and sequenced as per instructions.
1
Check that the gate valve on the discharge pipework is open.
Start the engine and engage the PTO. Check the direction of rotation of the
2
compressor.
Then set the motor speed so that the compressor is driven at the operating speed
3
of the application. Note that the input speed range of the compressor is 1000-
1600 rpm.
Check that the inlet blockage indicator does not indicate (show red) a blocked
4
filter/inlet pipe work (see inlet filter section).
Whilst the compressor is operating, check the pipe work for leaks. Stop the
5
machine and tighten fasteners if necessary.
Partially close the gate valve to raise the discharge pressure to 0.2 bar below
6
the relief valve full bypass setting (stamped on relief valve). Check the system
for leaks. Stop the machine and tighten fasteners if necessary.
If all is well, continue to run the compressor until the total test time reaches
7
30 minutes. Re-check for air leaks.
Slowly increase the pressure beyond the stamped setting (on valve) to operate
8
the relief valve.
The relief valve should crack (begin to lift/open/blow off) within 10% below the
set pressure. Slight leakage prior to cracking is permitted at up to 0.5 bar g below
the set pressure.
The relief valve should then fully open (full bypass) within 150mbar of the
set pressure.
Slowly reduce the pressure until the relief valve re-seats (should be before
9
0.5 bar g (7 psi) under the full bypass pressure).
10 Check that all fastenings are still tight and flanges are leak free.
Return the engine speed to tick over, disengage the PTO, and then stop
11
the engine.
12 Remove any test apparatus, disconnect discharge hose and fit a blanking cap.
