10.4 - Electrical Connections

Re-tighten periodically the electrical connections.

10.5 - Water Piping System

Once a year, drain the piping system and check the furring-up of
the pipes.

10.3 - Fan-Motor Assembly

There is no particular maintenance on fan motor assembly.
However, during periodic maintenance, check that fan wheel rotates
freely without any friction.

10 - Maintenance

It is recommended to proceed to the following maintenance works
in order to ensure a good operation of the unit.

Before performing any maintenance operation, disconnect the
unit main power supply.

10.1 - Air Filter (optional)

Filters should be frequently cleaned to avoid clogging. They should
be inspected every 3 or 4 months under normal operating
conditions and be replaced if necessary (see drawings below for
the filter removal).

10.2 - Coils

Check that coil fins are not clogged or damaged.

To avoid mouldiness of coils caused by an accumulation of fine
dusts, it is recommended to clean them frequently. If necessary,
comb the coil fins with an appropriate tool.

Care must be taken not to damage the fins while cleaning them.

9 - Preliminary Checks Before Start-up

1. Make sure that system piping has been cleaned and all the air

has been purged, before starting up the unit.

2. Ensure that air filter (optional) is clean and properly installed.

3. Make certain that fan rotates freely.

4. Make sure that all water and electrical connections are properly

tightened.

It is not the manufacturer's policy to make recommendations
in terms of water treatment (please contact a specialised
water treatment company).

However, given the critical nature of this subject, particular
care should be taken to ensure that, if treatment is required,
it works effectively.

Using untreated or unsuitable water leads to excessive
clogging inside the coil tubes (earth and mud deposits,
corrosion, etc.) with major consequences on the thermal
efficiency of the unit and irreversible damage to the equipment.

The manufacturer and its representative decline all
responsability in the event of untreated or incorrectly treated
water being used.

If the water pipes are exposed to temperatures below 0 °C,
take the necessary precautions (draining, antifreeze, etc.) to
avoid the coils freezing. Adding antifreeze to the circuit reduces
the unit's performance (if necessary, please contact our sales
network).
