CONTROL METHODS
In winter use the heat recovery cell of VALLOX 75 and VALLOX 95 recovers heat from the
air leaving the dwelling and uses it to heat the air coming from the outside.
Electric radiator
VALLOX 75 / 95 units feature a 500 W post-heating radiator.The temperature of supply
air is adjusted at the thermostat regulatorlocated inside the unit.Adjustments can be made
within the range of 0...25°C.
POST-HEATING
In summer use the heat recovery cell is bypassed in VALLOX 75 and VALLOX 95 with anin-
built damper.
In the summer position airflow through the cell is prevented, and heat recovery bypass is
activated.

Post-heating radiator
Water radiator (VKL model)
VKL models come standard with a water radiator (P). Temperature of air going from the unit
is adjusted by a self-actuated thermostat valve (T). Heat pipes coming to the unit are connected
within the unit with 12 mm clamps (L) to the radiator.
Water radiator defrosting
Defrost thermostat (T) of the post-heating radiator (P) stops the unit when the temperature
of the water radiator goes below the setpoint, thereby preventing the freezing risk of the
water radiator. This also causes self-actuated one-way dampers (Y) to close, preventing the
flow of outdoor air to the unit. The unit starts automatically as soon as the risk of freezing
has passed. The threshold temperature of the risk of freezing can be set at the thermostat
(J) of the water radiator.
Though VALLOX 75/95 VKL units incorporate efficient freezing protection, at least detached
houses should be equipped with a separate heating circuit, with a water-glycol mixture (or
other non-freezing solution) as the heat transfer fluid. The system may be equipped with an
optional heat exchanger (V). Without non-freezing water-glycol mixture, there is a risk of
freezing in the post-heating radiator because it is in direct contact with outdoor air.

MAINTENANCE INSTRUCTIONS
Detaching and attaching of self-actuated one-way damper
(vacuum damper)
APut the hook of the damper (Y) rim under the back edge of the fastening collar (K) of
the fan (F). Then push the damper downwards until the steering edges of the valve go
inside the rubber collar.
Push the front edge of the collar with your finger.
Put the hook of the front edge of the damper below the front edge of the collar. When
detaching the damper, take the same steps in the opposite order. Self-actuated one-
way dampers are only used in VKL model units.

Thermostat sensor is not locked. The sensor is detached by
turning the sleeve to the direction shown by the arrow.
When reattaching the sensor, turn the sleeve to the direction
shown by the arrow to make the claws lock in the open
position, check that the green indicator dot is visible, and push
the thermostat sensor to the body of the valve.

Description of operation for VALLOX 75 / 95
Control of operation
Power supply to the unit is controlled with the 0/1 switch in the
distribution panel. There is also a service switch SS inside the
unit.
Fan speed adjustment
The Sand Efans of the unit are controlled depending on
operating conditions with a separate 4-step (1, 2, 3 and 4)
control centre HS located in the ventilation zone, or with a
cooker hood.
Supply air temperature
Regulating thermostat T1 controls the operation of the electric
radiator R, keeping the supply air going out from the unit at the
setpoint.
Heat recovery bypass
Summer-time bypass of the heat recovery cell HR is done
manually by turning the HR damper Hin the bypass position for
the summer.
Heat recovery antifreezing
The antifreezing thermostat T4 of the HR cell keeps stopping the
supply air fan S, thereby preventing the risk of the freezing of
the HR cell. The fan starts automatically as soon as the risk of
freezing has passed. The threshold temperature of the risk of
freezing can be set at the thermostat T4.
Overheat protector of the electric radiator
The overheat protector T2 of the radiator Ris triggered and
power supply to the heating unit is stopped, if the temperature
of the thermostat exceeds +80°C.
The overheat protector is reset manually.

INSTALLATION
VALLOX 75/95 location
VALLOX 75 / 95 is mounted in a place where temperature is more than +10 °C. The unit
must be located in a place where the acoustic disturbance for residents is minimal. If residents
can boost ventilation so that it exceeds the ratings for the time of operation, the sound level
rating may be exceeded by +10 dB. If needed, the unit shall be encased.
Ceiling mounting
VALLOX 75 / 95 can be equipped with an optional easy-to-use ceiling mounting plate (patent
pending). The ceiling mounting plate is fixed to the ceiling with M8 thread bars. Fix the bars
so that they stand the weight of the unit, i.e. approximately 40 kg.
The ceiling mounting plate has to be fixed horizontally in order to ensure that the unit will be straight.
Installation
Lift the unit straight upwards, till the locking wings on the sides of the mounting plate lock
into the side plates of the unit. You can detach the unit from the mounting plate by releasing
the locking wings from the side plates.
To facilitate mounting, you may use a lubricant,
such as O-ring grease, in the collar sealings.
Mounting accessories include rubber silencers,
base plates and nuts. Thread bars are
not included in the delivery.

Wall mounting of VALLOX 75 / 95
Wall mounting
The delivery of VALLOX 75/95 includes wall mounting accessories with the exception of
screws. The unit has to be mounted horizontally and vertically straight.
Wall construction
Pay attention to the wall construction when mounting the unit. Avoid mounting the unit on
a hollow, echoing dividing wall and on a bedroom wall because of air conduction, or
prevent air conduction.

VALLOX SILENT non-return valve
ensures a condensing water
connection that will not gurgle.
Vallox water seal “SILENT”
VALLOX 75/95
INSTALLATION

The condensing water pipe must
have a downward slope.
The condensing water pipe must
never be connected directly to the
sewer.
It is not recommended to connect
a condensing water pipe to a water
seal or a floor drain where hot
wash or shower water goes.
(If hot wash water goes to the floor
drain and condensing water seal
gets dry during the summer,
steaming air is released from the
drain to the unit's negatively
pressured outlet side, which causes
water to condense from the air in
the pipe. A condensed water drop
may generate an audible sound
from the floor drain. The sound
may be generated in winter as well
if the water seal of the condensing
water pipe is not filled and does
not prevent air from flowing. Air
flow and the formation of water
drops in the condensing water pipe
should be prevented.)
The delivery does not include a
water seal nor the pipe and its
components.

and filling
Normally to the floor
drain
May generate sound when
the water seal gets dry.
When there is no condensing water, the
water seal may get dry in 1 to 4 weeks.
To the water seal in
the wash basin
May generate sound
when the water seal
gets dry.
Normally to the floor
drain with a long water
seal
A long water seal ensures
soundlessness for a long
time.
Straight to the floor
drain without a
water seal
The downward slope of
the pipe is so steep that
a water drop generating
sound cannot remain in
the pipe.
Normally to the floor
drain
The pipe has a fork which
decreases suction from the
floor drain. No sound. Water
seal not necessary. The fork
can also be used to fill the
water seal if such a seal is
used.
Normally to the floor
drain through a
funnel
No water seal. No sound
because there is no
suction in the pipe. The
unit sucks replacement
air from the funnel.
Normally to the floor
drain through a non-
return valve
The valve prevents air flow
in the pipe but lets
condensing water flow into
the floor drain. No sound.
To the collector
No sound.
