5.2 Maintenance chart

Recommended in-
tervals

The following chart details the recommended maintenance intervals, under normal
operating conditions. EXHAUSTO recommends maintenance is adjusted to suit the
actual operating requirements.

Component

Procedure

Once a

year

Twice a

year

Filters*

Replace when the display shows the filter alarm

We recommend that both filters are replaced at the
same time

NB:

The control system will give an ‘early warning’

when a filter is becoming soiled, so that there is time
to order a new filter or call a service technician

Filters should be replaced at least:

X

Filter equipment

Check that all the seals are tight

X

Seals and sealing strips

Check that all the seals are tight

X

Fans and heating coil (ac-
cessories)

Check
Remove the fan unit. See section "Internal transport
with reduced weight"
Cleaning. See next section

X

Rotary heat exchanger

Check
Cleaning when required. See next section

X

Safety functions check

Fire thermostats
Temperature sensors on heating pipe (accessories)

X

Closing damper

Function check

X

Motor valve and circulation
pump (accessories)

Function check

*Filters

Only use original filters

The provided filter data and pressure loss graphs (section 7) are based on the
use of original filters

EUROVENT certification is only valid if original filters are used

Use of non-original filters may cause leakage in the VEX and impair filter func-
tion

EXHAUSTO recommends that you register the filter replacement date to en-
sure filters are replaced at the correct intervals
