USER INSTRUCTIONS: MAINTENANCE, CLEANING
▪ These units are built using modern technologies that assure long-term high efficiency and performance levels.
▪ It is essential to establish and follow a regular inspection and maintenance programme. The following maintenance programme was established
considering optimal air pollution conditions in the place of installation. The indicated maintenance frequencies are purely indicative and can vary
depending on effective operating conditions. The most aggressive atmospheric conditions occur when there is an abnormal quantity of industrial
fumes, salts, chemical fumes and industrial dust.
TO CLEAN THE UNIT
ATTENTION! Disconnect the unit from the main power supply before cleaning it.
Do not direct jets of water on the unit. This may cause electrocution or damage the unit. Do not use hot water, abrasive substances or solvents; use
a soft cloth to clean the unit. If possible, do not use while the area is being cleaned.
ROUTINE MAINTENANCE PERFORMED By USERS
N.B.: Accurate maintenance always saves money and increases safety!
At the start of each air-conditioning season, at the start of each heating season and then at least once a month, perform the following operations:
▪ Clean the outside of the unit with a damp cloth.
▪ AIR FILTER: Before cleaning the filter, remove it from the unit.
Removing the filter
a-LIFE2 HP DLIV/DFIV - Turn the filter by pressing on the free side of the filter housing and remove it by sliding it along the guides.
▪ The filter can be cleaned by shaking it, washing it with detergent under running water, or by blowing it with compressed air. IMPORTANT: to clean
the filter, the jets of air or water must be directed in the opposite direction to that of normal air extraction and they must not be so violent as to dam-
age the filter medium. If the filters are cleaned with water, leave them to dry with care before using them so as not to compromise system efficiency.
▪ CONDENSATE DRAIN: During the summer season, make sure that the condensate drain is not obstructed and that the tray is free of dust and the
like. Any dirt could block the drain and cause the condensate to overflow.
