Service and Maintenance
Service and maintenance are vital for problem-free opera-
tion of an Airmaster unit and its equipment. The majority
of servicing consists of cleaning and inspection of the
condensate system and filter change. We recommend that
all service is performed by authorised experts.
Please contact your service partner by phone or mail to
agree service provision.
7.1.
External Cleaning
NB: The air handling unit must be switched off before
cleaning.
To remove dirt from the control panel, sensors, cooling
module and air handling unit, use a soft, damp cloth and
clean water, or water with a mild detergent added (e.g.
washing up liquid).
NB: Do not use aggressive substances (e.g. turpentine)
or sharp objects (such as a scraper) to clean the ventila-
tion system components.
The extraction grille and air vents must be regularly cleaned.
We recommend vacuum cleaning using a soft brush nozzle.
The space between the air handling unit and ceiling can be
dusted using a feather duster. A soft brush vacuum nozzle
can also be used if there is sufficient room.
7.2.
Internal Cleaning
Internal cleaning is recommended when changing filter. If
dirt gets in to an Airmaster unit/cooling module, remove
with a vacuum cleaner or soft brush.
REMEMBER! The unit must be switched off and discon-
nected from the mains before the access covers on the
unit and cooling module can be opened.
NB: Check the cleanliness of components when per-
forming internal cleaning. This applies in particular to
the counterflow heat exchanger and fans.
7.3.
Cleaning the Condensate System
N.B. The condensate system must be cleaned minimum
annually and must be controlled at every filter change.
Condensate pump:
Supply hose
Drain hose
Float housing
Condensate pump
The condensate pump is fitted as standard on the cooling
module, and is an optional extra for the air handling unit.
AMP 1200: The condensate pump is behind a service access
cover under the extract air panel.
• Remove the condensate tray (cooling modules only).
• Remove the float housing and supply hose.
• Open the float housing cover.
• Clean all individual parts.
• Replace all the above in reverse order.
NB: All condensate hoses in the condensate system
must be secured again with a suitable hose clip.
• Pour approx. a half litre water into the condensate
tray, switch on the power briefly and check that the
water is pumped out and that there are no leaks.
Condensate tray:
A condensate tray is fitted as standard to all air handling
units and cooling modules.
The plug, drain house and tray can all be easily removed for
cleaning the drain and hose. We recommend cleaning the
drain and hose when changing filter.
