8.2.2 Notes on installation of connecting armatures
Only put components (high pressure hoses, connections etc.) into the high pressure side if
they can withstand the pressure and the flow rate. Look at the registration on the
components.
Regularly check the high pressure hoses, fittings and jetting (i.e. nozzles, spray bar) for
signs of leakage. In the case of leakage stop the high pressure pump system immediately.
Remove leakage only when the system is switched off and depressurised.
The HDP 502 / S 1100-50 connections for instance are:
 Suction hose
Before connecting the water supply (hose) onto the high pressure pump (suction
connection) rinse the suction hose.
Remove protective cap from the suction coupling and ensure that the coupling is clean.
Let the water run for one minute or so. Then connect the water inlet line with the
suction coupling.
 High pressure hose
Remove hose protection from H.P. water connection. Ensure the mating thread is
clean and then smear with Molykote (1000 anti-seize) grease. Remove the cap from
the hose outside and repeat the cleaning and greasing procedure. Connect the hose.
The cleaning, greasing and hose arrester procedure should be observed when fitting
hose extensions.
 Separate oil cooler
supply
Normally oil cooler supply is from the suction chamber but if the suction water is above
35° a separate supply with a lower temperature must be provided.
 Bypass line
Connect the bypass hose/line (onto the pressure regulating or bypass valve). The
bypass line is used to dispose of the water when the consumer is closed and the pump
is running without pressure. Connect the line with a suitable drain channel or collecting
place.
 Cool water line
Connect the cooling water hose. Connect the line with a suitable drain channel or
collecting place.
 Piston cooling
Never close off the piston cooling drain hose/line. The cooling water must be enable to
flow freely away. If necessary run the hose to a suitable container or similar.
 Control cable
Remove protective cap from electrical connector. Ensure they are clean and dry before
connecting.
 Pneumatically control
line
Connect the pneumatically control hose (i.e. for pneumatically driven high pressure
pistol) onto the push lock connection of the unit. Ensure that connections are in order
and clean.
Never connect or disconnect control cable when system is > LIVE <. Extremely dangerous!
Never tighten up leaky hoses under pressure. Remove leakage only when the system is
switched off and depressurised.
