The Axair PH7 is an all-season unit for air humidification
and air purification.
Via the level regulating valve (2) the water flows from the
water tank (1) to the base tub (3). The impeller (4) sucks up
the water from the base tub and projects fine drops towards
the activated charcoal vaporizer mat (5).
The fan (7) located in the upper part of the fan housing takes
in ambient air. The filter (6) purifies the air which is then
moistened by the activated charcoal vaporizer mat. Finally,
the purified and moistened air is exhausted to the room, via
the slots in the upper part of the housing.
Note: If the Axair PH7 is operated without water it works as
air purifier only and no humidification takes place.
3.3 Unpacking, checking the delivery and
removing the transport lock
•Unpack the Axair PH7.
Important! The original packaging of the Axair PH7
was designed for optimum safety during transportation.
Please preserve the original packing material as well as
the transport lock (see below) in case you once have to
return the unit for some reason.
•Lift up the hood. Pull out the mains cable from the cable
duct in the air intake screen and carefully lift up the fan
housing. Then, remove the transport lock “A”.

•Check the delivery for completeness. The Axair PH7
is supplied ready for operation, equiped with a filter
(PH7: Triplex filter, PH7 Plus: Hepa filter) and the acti-
vated charcoal vaporizer mat.
Check the equipment for damage. Please report any
damage to your Axair supplier and to the carriers, as
required.
•Put on the fan housing. Lead the mains cable via the
cable duct in the air intake screen down to the base tub.
Then, put on the hood.
4Notes on correct location
Caution! The Axair PH7 must not be installed
in hazardous locations and the unit must not be used
in rooms where water splashes may occur.
Please observe the following notes for the correct position-
ing of the Axair PH7:
Important! Empty the base tub before moving the unit,
otherwise water could possibly escape.
–To ensure proper operation place the Axair PH7 on a
solid horizontal surface only.
–To make sure the air is entirely recirculated do not
locate the Axair PH7 in narrow recesses, behind
curtains etc. Keep a minimum space of 0.5 m be-
tween the unit and nearby walls or furniture.
Make sure the air intake and exhaust slots are not
covered thus ensuring the purified and moistened air
can leave the top of the unit without hindrance.
–Do not locate the PH7 close to cold outer walls and do
not expose the unit to direct sunlight or powerful heat
sources (lamps, radiators, etc.).
–If the Axair PH7 is used in a particular location for an
extended period the filter and the activated charcoal
vaporizer mat absorbs the odour of the room. When
moving the unit to another location, the Axair PH7 emits
the odour of the previous room for a certain time. This
may be inconvenient if the unit is moved from a room
heavily loaded with smell to an almost neutral environ-
ment.
Note: if the unpleasant odour does not disappear after a
certain period, the filter and the activated charcoal va-
porizer mat must be replaced.

Connect the unit to the mains
•Make sure the required supply voltage (see type plate
inside the housing) matches the local mains voltage.
To do so, disassemble the fan housing, check the spec-
ification on the type plate, then assemble the fan hous-
ing again. Please follow the information on dismantling
and assembly given chapter 6.2.
Caution! Do not connect the Axair PH7 to the
mains if the voltage does not match!
–Important! Never move the Axair PH7 if the water tank
or the base tub are filled with water. The water could
escape and moisten the filter thus making it unusable.
–Caution, fire hazard! Make sure the air intake and
exhaust slots are not covered by objects such as clothes
when the unit is in operation as this could cause danger-
ous accumulation of heat inside the unit.
•Connect the mains plug to the wall outlet.
Recommendation! Connect the Axair PH7 to a wall
socket featuring a fault current breaker (if available).
Switching on the unit/Setting the fan speed
Switch on the Axair PH7 via the On/Off
key. The unit starts running at the fan
speed selected last (the corresponding
fan speed LED lights).
Press the fan speed key to select the
desired fan speed according to the fol-
lowing table.

(at 45%hr and 23°C)
Notes on operation
–Check the level of the water tank on a regular basis and
fill up as required (see section “Refilling the water tank”).
Recommendation: for optimum purification the Axair
PH7 should always be operated with water. As an
exception to the rule, the unit may be operated without
water in rooms that are rarely aired thus preventing
excessive humidification (however, this should not be
done in the heating period). In this case the Axair PH7
works as air purifier only.
–Important! Never operate the PH7 without filter and
activated charcoal vaporizer mat.
–Caution, risk of damage! Do not insert foreign objects
into the air intake and exhaust slots.
Putting the unit out of operation
•Switch the Axair PH7 off, remove the mains plug from
the wall outlet and wait until the fan comes to a stop.
In case you want to put the Axair PH7 out of operation for an
extended period:
•Empty the water tank and the base tub. Clean the com-
ponents as described in chapter 6.2. Make sure the
water tank and the base tub are absolutely dry, then
reassemble the unit. Store the unit in an appropriate,
dust-free location.
