5.2 Bag filter (code ATEF)
The air filters in an air handling unit are designed to prevent dust and other
impurities from entering the building. They should also protect sensitive
components inside the unit, e.g. water coils
and heat exchangers, from exposure to
impurities.
The dust separation efficiency varies consid-
erably between various filter types. The dust
collecting efficiency also varies substantially.
It is therefore important to use filters of the
same quality and capacity when you change
them. Separation class is specified with
standard designations M5 for medium filters
and F7 for fine filters. Higher digits denote a
higher collecting efficiency.
The filters are designed for one-time use.
If they become fouled, the unit will lose
capacity. The filters should therefore be changed if the pressure drop across
them exceeds the specified final pressure drop. It is important to stop the unit
before changing filters to prevent dust from coming loose and being drawn
into the unit. The inside surfaces of the filter sections should therefore also be
cleaned when the filters are changed.
Inspection
Check the pressure drops across the filters. A manometer connected to probes
is used for these measurements. The probes are connected to each side of the
filters.

If the filter has reached its specified final pressure drop, it should be changed.
The final pressure drop is specified on the filter section decal (filled in when the
air handling unit is put into operation).

5.3 Filter cabinet (code ATET-08)
The filter cabinet is an optional extra and
can be used for
• aluminium filter on the extract air side
• carbon filter on the
supply air side
Aluminium filter Carbon filter, Black Ridge
The aluminium filter is intended for use
where the extract air contains grease par-
ticles to avoid grease being sucked into
the unit. The filter is a knitted mesh sheet.
The aluminium filter can be cleaned us-
ing hot water and a mild detergent.
The carbon filter can be used to remove odours in
the form of organic and odorous gases/vapours. The
carbon filters are fitted to the supply air side..
The carbon filters are Black Ridge filters, construct-
ed as compact and highly efficient, molecular filters.
The filters are designed for one-time use and the
filter is combustible in its entirety.
Inspection
Aluminium filter
Check the pressure drop across the filter.
A manometer connected to probes is used
for these measurements. The probes are
connected to each side of the filter. If the filter
has reached its specified final pressure drop,
it should be changed. The final pressure drop
is specified on the filter section decal (filled in
when the air handling unit is put into operation).
Also carry out a visual inspection of the filter for damage and deposits.

Operation and Maintenance Instructions
Envistar Top / Home Concept
DSTH140822.04.EN
Continuous product development may give rise to specification changes without notice.
Carbon filter
The function and lifespan of the carbon filters depends on the volume of air
that passes through and on the molecular density of odorous substances. This
means that the time intervals for filter replacement can vary from unit to unit
depending on operation mode and the volume of odorous substances in the air.
Units delivered with IV Produkt integrated control equipment are equipped with
the control function filter control – FLC (Filter Lifetime Control). FLC indicates
when it is time to replace the carbon filter. Indication is through an alarm on the
hand-held terminal display.
FLC calculates the volume of air passing through the carbon filters and triggers
the alarm for filter replacement when the preset value has been reached.
The volume of air passing through is measured in mega cubic metres (Mm3).
The function does not take into account the odour content of the air, which
means that the indication should be regarded as a recommendation for check-
ing the filter function. If no odours pass through, there is no need to replace the
filter.
Preset FLC values, as per the table below, are based on max. air flow over 12
months of full-time operation. If required, the value can be lowered in order to:
- change to more frequent filter replacement intervals for max. air flow
- retain the filter replacement interval of 12 months for lower air flows.
To change the value, see separate Climatix control documentation.

5.4 Rotary heat exchanger (code ATRR)
The purpose of the heat exchanger is to recover heat from the extract air and
transfer this heat to the supply air. This reduces the output required and the en-
ergy use.
A faulty heat recovery function through
reduced recovery efficiency entails in-
creased energy use. This also means that
the planned supply air temperature will not
be reached when outdoor temperatures are
low.
A conceivable reason for reduced recovery
efficiency may be that the rotor rotates too
slowly because the drive belt is slipping.
Rotation should not be lower than 8 RPM
during full energy recovery.
It is not usual for the rotor passages to be-
come fouled with dust, since the rotor is
normally self-cleaning. However, this might occur if the dust is of a sticky nature.
A reduction of the extract air flow, e.g. due to fouling of the extract air filter, en-
tails reduced heat recovery efficiency.
The units are equipped with a control function for the pressure balance over
the purge sector, which means that the pressure balance does not have to be
inspected or adjusted. For units supplied with IV Produkt integrated control
equipment, the function is activated at the factory. For units not supplied with
control equipment this function has to be connected to the unit.
Inspection
1. Shut down the unit via the control terminal and lock the safety switch in the 0
position.
2. Wait until the fans have stopped, then open the inspection door.
WARNING!
Positive pressure inside the unit, risk of personal injury.
Allow the pressure to drop before you open the inspection
doors.
3. Check that the rotor rotates easily. If it is sluggish, you might have to adjust
the bristled sealing strip.
4. Check that the rotor’s bristled sealing strip seals against the side plates and
that it is not worn. The bristled sealing strip is subject to wear and can be
adjusted or replaced if the need arises.
5. Check that the drive belt is properly tensioned and does not slip. If it slips, it
will have to be shortened. The rotor speed should not be lower than 8 RPM
during full energy recovery.
6. Check that the drive belt is intact and clean.
7. Check that the rotor’s inlet surfaces are not covered with dust or other impu-
rities. NB: Avoid touching the rotor inlet and outlet surfaces with your hands
or tools.

9. Check the differential pressure across the rotor. The purging sector is
factory-installed, set to the maximum open position. Depending on the
unit’s pressure ratios, the purging sector may need adjustment. An incorrect
setting may impair the efficiency. Inspection and adjustment should be
carried out as follows:
– Measure and write down the differential pressure between the outdoor air
(P1) and the extract air (P3).

Continuous product development may give rise to specification changes without notice.
Cleaning
• Remove dust by carefully vacuum cleaning using a soft brush.
• If the rotor surfaces are severely fouled by greasy dust, spray the rotor with
water mixed with a dishwashing detergent that will not corrode aluminium.
Alternatively, use detergent designed for heat exchangers, e.g. Re-Coilex
(see below).
• Compressed air at low pressure (max. 6 bar) can be used for blowing the
surfaces clean. To avoid damage, the nozzle should not be held any closer to
the rotor than 5–10 mm.
A hygroscopic rotor variant can absorb particles which in some cases give off
odours. To prevent odours arising, exercise run the hygroscopic rotor using the
integrated control function. If an odour still arises, we recommend cleaning the
rotor with e.g. Re-Coilex, see below.
Re-Coilex is a weak alkaline, highly concentrated, special cleaner
that is diluted with water and applied liberally with a pressure sprayer,
if possible when the unit is in use so that the detergent is sucked
through the rotor.
For cleaning it is recommended that the purge sector is fully open
and the rotational speed is 8 RPM. This assists with the sucking through of the
detergent. Post-rinsing is not normally required.
Re-Coilex is marketed by Resema AB.
Lubrication
The bearings and drive motor are permanently lubricated and do not require
additional lubrication.
