Maintenance
Be aware! Remove power supply, compressed air supply and medium
pressure before maintenance or reparations.
Maintenance and reparations should be done by qualified personnel.
Avoid direct contact with wastewater / medium. Wear protective gloves
during use, maintenance and reparations of the sampler.
Be aware! When removing the sample drain hose from the pincher the
danger of fingers entering the pincher occurs. This can cause serious
injuries.
Maintenance:
Regularly clean the plunjer, sample outlet pillar and sample drain hose
with a soft brush and tap water (depends on use and sample frequency).
Replace parts when necessary. Regular check if the seals on the plunjer
are worn.
Disassembly:
•
Remove the front TRI-Clamp coupling and pull the sampler from
the piping.
• Remove the 2
nd
TRI-Clamp coupling and pull the enclosure away
from the cylinder.
• Place the ILS-service tool around the axle and mount it with 2 TRI-
Clamp couplings.
• Place compressed air on coupling B and the plunjer shoots
backwards
(BE AWARE OF YOUR FINGERS!) .
• Remove the ILS-service tool and pull the enclosure loose from the
last seals on the plunjer.
•
Loosen the locking nut from the plunjer and loosen the plunjer
from the axle
Revision:
Replace the seals on the plunjer (3 in fig 5.6a), 3x Viton large (4), 1 Viton
small (2) and 1 Teflon (1). Loosen the black protection cover from the
cylinder to replace the x-ring on the axle.
Mounting
Work opposite to the disassembly to assemble the sampler.
When placing the seals make use of some form of lubricant.
