MAINTENANCE
General Rules
To validate the contractual warranty, the machine must be set at work by technicians from an authorized assistance center. Before
they are called, check to make sure that all parts of the installation have been completed, the unit levelled, the wet connections made
with the relative air vent and the electrical connections made.
General Rules
Maintenance is of extreme importance if the plant is to operate in a regular way and give fade-free service. Have extraordinary mainte-
nance work done by qualified and authorized personnel, according to EU Regulation 303/2008 of 2 April 2008 (and later) that requires
companies and technicians that perform maintenance / repair, leakage checking and recovery / recycling gases must be certified as
required by local regulations. Comply with the safety precautions given in the relative section of this manual and take all the necessary
precautions. The following information is only a guide for the end user.
Maintenance keeps unit efficiency, reduce the speed of deterioration over time and collect information and data to understand the
efficiency of the unit and prevent failures. We suggest to prepare a booklet of installation according European legislation.
Routine maintenance
The inspections described below, to which the unit must be subjected, do not require specific technical know-how.
They merely include a few simple inspections involving certain parts of the unit.
Call an authorized assistance center if actual maintenance work is required.
The table below gives a recommended list of inspections which should be carried out at the indicated intervals.
Provide controls and interventions more frequently in case of heavy (continuous or intermittent high, close to operating limits, etc ...)
or critical (essential service such as data centres, hospital etc ...) use.
• Structure of the unit
When checking the condition of the parts that form the structure of the unit, pay particular attention to the parts liable to rust.
If traces of rust are noted, they must be treated with rust-inhibitor paint in order to eliminate or reduce the problem.
Check to make sure that the external panels and the fans of the unit are well fixed.
Bad fixing gives rise to noise and abnormal vibrations.
• Hydraulic circuit
Check visually to make sure that there are no leaks in the hydraulic circuit. If the pumping module accessory is installed, it is advisable
to make sure that the water filter is clean.
• Electrical system
Make sure that the power cable that connects the unit to the distribution panel is not torn, cracked or damaged in a way that could
impair its insulation.
