Maintenance
Instruction and training
The owner of the installation is
responsible for the training and
instruction of the maintenance
engineers.
Before maintenance can be
performed on the satellites,
ensure that the installation
is fully depressurised.
Safety conditions for the
maintenance engineers
Safety
•
All safety devices including safety
switches and safety covers must be
properly reinstalled and functioning
normally after maintenance activities
have been carried out.
•
The installation should NEVER be
operated when all or even part of the
safety system has been turned off.
Maintenance
•
The installation may only be
maintained by authorised personnel.
•
The maintenance engineers must be
familiar with the contents of this
technical documentation and be able
to carry out all the instructions given.
Preventive maintenance
•
Regularly check the satellite for leaks
and function. Remedy any leaks
immediately.
•
Regularly check the chemical suction
hose including the injector for
contamination
[9]
.
Contamination
influences the operation of the
injector. If the injector does not let
sufficient litres through (for foaming,
± 8.0 litres of water per minute must
flow through the injector), the inside
is probably blocked. Close all valves
of the satellite and depressurise the
hose and optional hose reel by
operating the spray gun until no
more liquid comes out; for this
purpose, disassemble the injector,
which is screwed at left side, with
screwdriver, the white marked
injector is for the foaming liquid and
the red one (only for Blocksat RFD)
for the disinfection liquid. The
injector can now be removed from
the block to be cleaned. Check before
assembly, assure that the O-rings are
undamaged and free from dirt,
grease them with food grease; screw
the injector all the way in until it
stops.
