9 - MAINTENANCE
GENERAL
Maintenance must be done by authorized centres or by
qualified personnel
The maintenance allows to:
• maintain the unit efficiency
•
reduce the deterioration speed to whom every
equipment is subject over time
•
assemble information and data to understand the
state of the unit efficiency and avoid possible
damages
Before checking, please verify the following:
•
the electrical power supply line should be isolated
at the beginning
•
the unit isolator is open, locked and equipped with
the suitable warning
•
make sure no tension is present
After turning off the power, wait at least 5 minutes
before accessing to the electrical panel or any other
electrical component.
Before accessing check with a multimeter that there
are no residual stresses.
Perform an inspection every 6 months minimum.
The frequency, however, depends on the use.
In the event of frequent use it is recommended to plan
inspections at close intervals:
• frequent use (continuous or very intermittent use,
near the operating limits, etc)
• critical use (service necessary
).
INSPECTIONS FREQUENCY
UNIT BOOKLET
It’s advisable to create a unit booklet to take notes of
the unit interventions.
In this way it will be easier to adequately note the
various interventions and aid any troubleshooting.
Report on the booklet:
•
data
• type of intervention effected
•
intervention description
• carried out measures etc.
PUT AT REST
If a long period of inactivity is foreseen:
•
put the unit in OFF
• wait a few minutes to allow all the actuators to
reach the rest position
• Turn off the power in order to avoid electrical risks
or damages by lightning strikes
It’s recommended that the starting-up after the
stopping period is performed by a qualified technician,
especially after seasonal stops or seasonal switch.
When restarting, refer to what is indicated in the
START-UP section.
Schedule technical assistance in advance to avoid
hitches and to guarantee that the system can be used
when required.
STRUCTURE CLEANING
The structure of the unit is done in plastic material EPP
(expanded polypropylene)
HBF fire resistance classification.
For cleaning the structure it is recommended to use products
without aggressive chemicals.
