Daily Maintenance
The following maintenance checks should be carried out daily by the operator/customer. Please note
that the units are not generally user serviceable and no attempt should be made to rectify faults or
problems found during daily checks unless competent and equipped to do so. If in any doubt, contact
Data Aire Service Department.
•
Press the ‘Alarm’ key on the display module to ensure no fault messages are displayed.
•
Read the operating conditions and temperatures at the display module using the display keys
and check that these are within the operating limitations for your installation site.
Maintenance/Inspection Checklist
The maintenance operations detailed in the Maintenance/Inspection Checklist should be carried out on
a regular basis by a suitably qualified Service Technician. It should be noted that the interval necessary
between each ‘minor’ and ‘major’ service can vary depending on, for instance, application, site
conditions and expected opera
ting schedule. Normally a ‘minor’ service should be carried out every
three to
six months and a ‘major’ service once a year. It is recommended that Data Aire Service
Department be contacted for recommendations for individual sites.
CAUTION: Personal protective equipment is to be used for maintaining
and servicing equipment. Some operations when servicing or maintaining
the unit may require additional assistance regarding manual handling. This
requirement is down to the discretion of the Service Technician. All
maintenance and servicing must compliance with environmental and safety
regulatory requirements.
CAUTION: Remember do not perform a lift that exceeds your ability.
WARNING: Turn OFF the disconnect switch to all remote electric facility
power to the unit before servicing or maintenance.
Air Filters
The air filter section is an integral part of the environmental control system, designed within the unit for
easy front and/or side accessibility. An initial set of filters are factory installed in the unit. The filters are
4-inch (100 mm) deep unless otherwise specified, disposable, pleated design, extended-surface,
nonwoven, reinforced cotton fabric; supported and bonded to welded-wire grid; enclosed in cardboard
frame design rated not less than MERV 8 per ASHRAE Std. 52.2.
A dirty air filter differential switch for alarm activation is included. Air filters should be checked on a
regular basis and changed when they become dirty. This will ensure efficient operation of the unit.
Spare air filters should be kept in stock as these tend to be a frequently replaced maintenance item.
Air filters may require changing as often as monthly dependent on room or space conditions. New
installations with construction dust will quickly clog filters requiring new filters.
