9.1 CHECKS BEFORE COMMISSIONING
Ensure that the installation pipe work has been cleaned and
bled of any air, before commissioning the unit.
Check that the condensate evacuation pipe is connected
and provides effective condensate drainage.
Check that the filter is clean and correctly installed.
Check that the fan rotates freely.
Check that all hydraulic and electrical connections are
correctly tightened.
Check free flow by pouring water into the indoors tray.
Follow the directions for treated air distribution.
9.2 GENERAL INSTALLATION
Carry out a visual inspection of the installation in
operation.
Check the overall cleanliness of the installation and check
that the condensate evacuation is not blocked, particularly
that of the evaporator coil.
Check the condition of the condensate tray.
For the installation to operate correctly, it is imperative that
the air filter, located on the air intake of the treated air coil,
is cleaned regularly.
Check the connections seals and, if required, insulate the
evacuation pipes to protect against frost or condensation.
Check that the air distribution flaps are open.
Cleaning intervals vary depending on the amount of
impurities in the air to be conditioned. It is recommended
that the filter is replaced at regular intervals.
A dirty filter creates a decrease in air flow across the heat
exchanger, which decreases the installation’s output and
hinders fan motor cooling.
Check the state of cleanliness of the indoors coil.
9.3 ELECTRICAL ELEMENTS
Check that the mains supply cable is free from any damage
which might effect insulation.
Check the tightness of the electrical connections.
Take care !
