AREO ACP
8 MAINTENANCE
The routine maintenance operations to be performed on AREO ACP fan
heaters mainly concern the heat exchanger. It must be cleaned to eliminate
dust build-up, which tends to obstruct the spaces between the fins,
resulting in a decrease in the quantity of heat exchanged.
This job may be done using jets of compressed air.
If grease has also deposited you can wash the fins, taking care not to wet
the electric motor and making sure the finned block is thoroughly dried
before starting the fan heater.
It is recommended to carry out these operations at least once a year before
the start of the heating season.
The electric motor requires no maintenance as it is of the closed type with
self-lubricating bearings.
Every time you start up the unit after it has been off for a long time, make
sure no air is trapped in the heat exchanger.
Special care should be taken when carrying out maintenance work:
- some metal parts may cause injuries; wear protective gloves.
- maintenance may be performed exclusively by specialised personnel;
contact your dealer or installer.
- For safety reasons, before carrying out any maintenance or cleaning
jobs, turn off the main switch of the unit to disconnect the power supply.
- If any work needs to be done on a unit that is working with hot water,
it is advisable to shut off the hot water (by means of the on-off valves)
and allow the fan to run for a few minutes until all the metal parts have
cooled down before carrying out any job on the fan heater.
Stop the fan and disconnect the unit from the power supply before
working on it.
