Other residual risks can be identified by introducing bodies within the fan when it is in operation and when it
is off. The introduction of solid bodies can cause immediate breakage of the fan with consequent projection
of the parts outside the machine. This situation can endanger people and cause damage to things within the
range of action of the machine.
GENERAL MAINTENANCE INSTRUCTIONS
The HD 160, HD 230, and HD 300 require the following maintenance:
Water filter
: Check the condition of the filter each time before starting up the
machine. Unthread the filter cannister to access the filter. Clean the filter with a jet
of water. As necessary, remove the O-ring and soak the filter in nozzle cleaner for
30 minutes. Flush with hot water. Re-install. Any traces of iron oxide (rust), scale or
other form of oxidization on the surface of the filter are a result of poor water quality.
Additional filtration may be needed.
Remove any residue of organic substances, such as small algae, using neutral
soap. Do not use cleaning solvents as these can damage the O-rings on the filters.
Make sure the filter is properly in place before threading on the cannister. Check the
condition of the seals before putting the machine into service.
Nozzles
: Remove the nozzles by hand using a 5/8” socket. Disassemble the
nozzles using a 5/8” socket/wrench and a 5/32 Allen wrench. Brush slots on the top
of the nozzle inserts with a stainless steel wire brush to remove all debris. Remove
the O-ring from the nozzle body. Soak the nozzle body and insert in nozzle cleaner
for 30 minutes. Flush with hot water and then compressed air. Re-assemble.
Inspect nozzle threads Clean the nozzle and crown threads as necessary. Thread
the nozzle into the crown (hand tight only).
Plumbing
: Flush with potable water and drain the unit after each use. Periodically
(or under freezing conditions), clean and drain the unit plumbing by removing the
hose that feeds the nozzle crown and flush the units plumbing by running the pump
with potable water for 30 seconds. Remove the top nozzle from each crown and
insert a pressurized water supply into the open nozzle port to flush the crown.
Repeat with compressed air. Replace the nozzle. Replace the feed hose. Open all
drain valves.
Water pump
: consult the respective manual.
Keep the system clean at all times.
