Maintenance and servicing instructions
(see chapter entitled
Maintenance
)
Safety instructions
•
The unit must be installed and operated in compliance with relevant standards (e.g. DIN, VDE, UVV) or in
accordance with regulations laid down by the respective country.
•
Some functions (e.g. diagnosis, manual operation) allow direct manipulation of the plant to be monitored without
locking or monitoring. Only trained staff should use these functions, which can only be accessed after entering a
password.
•
If you notice that the device is malfunctioning, switch it off immediately. Subsequently shut off the water supply
and contact our service staff.
•
Do not try to repair the unit (loss of warranty rights); always contact authorised service staff. This is the only way to
ensure reliable and safe operation of the plant.
•
After a protective circuit (fuse) has been tripped, attempt to eliminate the cause of malfunctioning (e.g. replace a
defective valve) before reactivating the protective circuit. Frequent tripping is always due to an error which, in
certain circumstances, may also cause damage to the unit.
•
Always observe the safety instructions about working with reagents, chemicals and cleaning agents.
•
Always adhere to hazard warnings and safety tips when using reagents, chemicals and cleaning agents. Please
adhere to the respective safety data sheet! Download the safety data sheets for the supplied reagents at
http://www.heyl.de .
Non-compliance with these instructions can damage the unit as well as the plant and may result in a loss of
warranty rights.
