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.
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.
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.
c
ommiSSioninG
Check the connections seals and, if required, insulate the
evacuation pipes to protect against frost or condensation.
Take care !
Follow the directions for treated air distribution.
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.
Check the earth connection.
This list is not comprehensive. Other checks can be
carried out, in relation to the environment and the unit's
operating conditions.
