Start-up
Observe the follow ing prior to start -up:
IT IS OF VITAL IMPORTANCE THAT THERE ARE NO PERSONS UNDERNEATH THE
VEHICLE DURING START-UP AND DURING OPERATION!!
Preservation
The rotors of the compressor are sprayed w ith an anti-corrosion agent prior to delivery.
During the initial operation this agent w ill evaporate as the compressor heats up. Since the
RTI-installations are all tested a few minutes, the anti-corrosion agent on the rotors w ill
have evaporated.
Topping up of lubricating oil
Check before start-up if the correct amount of lubricating oil is on the dipstick. The correct
level corresponds to the mark on the dip stick. See chapter 1.4
Checking the direction of rotation
Looking tow ards the drive shaft, the compressor must rotate clockw ise.
The compressor must be started and stopped in a fully unloaded condition, w ithout any
back pressure.
Never start against any back pressure. (Remove blanking cap or connect hoses.) This could
damage the shear pin coupling.
Switching-on
We refer to the truck’s instruction booklet, to sw itch on the PTO (only w ith closed
enclosure).
It is very important not to exceed the maximum speed range as reported in the inspection
report and as displayed on the da
shboard of the driver’s cab.
Together w ith the compressor, the integral oil pump w ill also start to run and w ill ensure
the supply of oil to lubricate the bearings and the gears. The oil pressure shall not fall
below 0,3 bar. With cold oil, it may occur that the required oil pressure is built up only
after a short operating time, due to higher viscosity. Check the air indicator clock. When
“ red” , the compressor must be sw itched off. See inspection checklist.
The minimum engine speed cannot go below 800 r
pm w ithout the truck dealer’s consent.
Vacuum installation
With a vacuum installation t he vacuum valve must be set to -0.5 bar. Please note: the
vacuum valve should be set w hen testing the installation before initial operation. The
vacuum valve has not been set w hen the installation is delivered as a building kit
(w ithout mounting by RTI).
CAUTION
After a short period of time, the compressor w ill reach maximum running temperature.
When sw itched-on, it not permitted to loosen the catches on the enclosure!!
We recommend the use of safety gloves w hen disconnecting hoses or couplings from the
enclosure, after the installation has been sw itched-on.
NOTE
When cleaning the tank vehicle by means of a steam jet device, w ater may penetrate
inside the compressor via the oil seals. To avoid corrosion, the compressor shall be set into
operation for a short period of time after cleaning.
The non-return valve installed in the discharge silencer is not intended to prevent flow -back
of material. Its purpose is to prevent the reverse operation of the compressor for an
extended period of time.
It is not permitted to use the attached relief valve as blow -off control valve.
