Air flow measurement outlets
The fixed air flow measurement outlets
are located behind the cover plate.
You can measure the total pressure of
the supply and extract air ductwork at
the measurement outlets using a
pressure gauge.
Compare the pressure readings with
the adjoining air volume curves to see
unit air flows at various adjustment
positions.
The red measurement hose gives the
pressure reading for the supply air fan
curve and the black hose the pressure
reading for the extract air fan curve.
Observe unit model and setting
(summer or winter).

Speed selector
Vallox 132 E comes with a four-step speed selector switch. The flush-mounted switch is mounted
in a standard instrument box. The switch can be used to select four of the eight speeds for
the unit. Speeds 2, 4, 6 and 8 have been preselected for the unit. An expert may select
different speeds at the transformer of the unit.
Remote monitoring control
It is sometimes necessary (for example in public facilities) to control the unit by remote
monitoring. The unit can then be controlled by VALLOX control centre 1993A YK, for instance.
Two speeds and one bypass speed can be chosen at the centre; the bypass speed can be
used to bypass the two first speeds. The standard four-step switch can also be replaced with
a corresponding control system, which must be planned by an expert for each specific case.
Control with a cooker hood
If cooking smoke abatement is connected directly to the unit, it can be controlled with cooker
hood PTXP/i132 or PTXPA/i132.

Water radiator freezing protection
VALLOX 132 E VKL comes standard with a thermostat, which protects the radiator against
freezing. It stops the unit when radiator temperature goes below +5 °C. When this happens,
the self-actuated dampers close. The unit restarts and the dampers open as soon as radiator
temperature exceeds +10 °C. The stopping threshold can be adjusted.
The thermostats are located below cover 1.
Note! Power supply to the unit must be turned off on the electric board before opening the cover.

CONTROL DIAGRAM and DESCRIPTION OF OPERATION/Electric radiator
VALLOX 132 E (electric post-heating radiator)
Control of operation
Power supply to the unit is controlled with the 0/1 switch in the distribution panel. There is also a
maintenance switch HK inside the unit. It stops power supply when the door of the unit is opened.
Fan speed adjustment
The S and E fans of the unit are controlled depending on operating conditions with a speed selector
switch NK in four steps.
Supply air temperature
Regulating thermostat T3 controls the operation of electric radiator J, keeping the supply air going
out from the unit at the setpoint.
Preheating
The preheating radiator can heat outdoor air and decrease the stopping of the fan. Thermostat T5
switches the radiator on before thermostat T4 stops the supply fan.
Preheating radiator overheat protection
Overheat protection thermostats T6 and T7 monitor the operation of preheating radiator E, preventing
the surface temperature of the radiator from exceeding the threshold. When temperature exceeds
the threshold, the overheat protector trips and power supply to the radiator stops. Overheat protector
T6 is reset automatically, whereas overheat protector T7 is reset manually.
Post-heating radiator overheat protection
Overheat protection thermostats T1 and T2 monitor the operation of post-heating unit J, preventing
the surface temperature of the radiator from exceeding the threshold. When temperature exceeds
the threshold, the overheat protector trips and power supply to the radiator stops Overheat protector
T1 is reset automatically, whereas overheat protector T2 is reset manually.
Heat recovery bypass
Summer-time bypass of heat recovery cell HR is done manually by turning the HR damper FG in the
bypass position for the summer.
Heat recovery antifreeze
Antifreeze thermostat T4 of the HR cell intermittently stops supply air fan S, preventing the freezing
risk of the HR cell. The fan restarts automatically as the risk of freezing passes. The threshold
temperature for the risk of freezing can be set at thermostat T4.
Alarms
Pressure difference switches W1 and W2 are options, designed to monitor pressure difference on the
supply and extract air sides. If the pressure difference rises too high because of dirty filters or clogged
ductwork, an indicator is lit on the front panel of the unit.
Booster or fireplace switch function
It is possible to mount an optional fireplace switch TK for the unit. The fireplace switch can be a 15...20
minute timer equipped with opening contacts.

risk of the HR cell. The fan restarts automatically as the risk of freezing passes. The threshold
temperature for the risk of freezing can be set at thermostat T4.
Water radiator antifreeze
When the surface temperature of the water radiator goes below the threshold, the antifreeze thermostat
T3 of post-heating radiator J stops the unit and self-actuated dampers SP close. This decreases the
freezing risk of the water radiator. The unit restarts automatically as soon as the freezing risk is over.
The threshold temperature for the risk of freezing can be set at thermostat T3.

What the units include can vary depending on the sales area. 13
INSTALLATION
Location of the unit
Vallox 132 E is mounted in a place where temperature does not fall below +10 ºC. Without
protective casing, the unit has to be located in a place with no acoustic disturbance:
storerooms, utility rooms etc. Vallox 132 E can also be located in a damp room, but not
in a bathroom next to a sauna bath.
Condensing water
A water seal is recommended for the condensing water pipe. The condensing water pipe
must have a downward slope.
The condensing water pipe must never be connected directly to the sewer.
If condensing water is led to a water seal or floor drain where also warm washing or
shower water is led, the use of a VALLOX Silent water seal is recommended.
The water seal and the pipes and their parts are not included in standard delivery.
CEILING MOUNTING
Vallox 132 E 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 71 kg.
The ceiling mounting plate has to be fixed horizontally in order to ensure that the unit will
be straight. The outdoor air duct must be insulated against condensation, also between
the unit and the ceiling mounting plate.
Installation of the unit
Lift the unit straight upward, 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 seals.
Mounting accessories include rubber silencers, base plates and nuts. Thread bars are not
included in the delivery.

INSTALLATION
Wall mounting
Vallox 132 E is mounted on the
wall with a fixing plate as shown
in the adjacent figure.
Wall construction
Pay attention to the wall construc-
tion when mounting the unit. Avoid
mounting the unit on a hollow,
echoing dividing wall and on a
bedroom wall because of sound
conduction, or prevent sound con-
duction.
Condensing water
The delivery includes a water seal.
By connecting a pipe to the water
seal the water condensing from
extract air can be led to a floor
drain. The pipe must never be con-
nected directly to the drain. The
condensing water pipe must have
a downward slope.
The unit comes with separate
instructions for mounting and using
the water seal.

PIPE CONNECTIONS
Connection of VKL post-heating radiator to underfloor heating circuit
To minimise the risk of freezing involved in the connection the system has several antifreeze functions.
1. The unit stops if supply air temperature goes below the set temperature and automatically starts as soon as
temperature rises.
2. When the unit stops, the self-actuated dampers (E) close.
Use of VKL post-heating radiator
• The temperature of heating water shall be adjusted according to the temperature of outdoor air.
• No water must be led into the radiator of the unit until the system has been adjusted for operation and the heating
network has heating on or it has been otherwise ensured that the radiator will not freeze.
• Water circulation in the heating network connected to the unit and the circulation pump must not be stopped during
the heating season.
• The base volume of water flow into the radiator of the unit can be adjusted with valves (R), which can also act as
stop valves.
Other connections
Heat can be conducted to the post-heating radiator of Vallox 132 E VKL in other ways than described above.
It is possible to build a separate circuit for the radiator if higher power is desired, or the risk of freezing can
be eliminated by using non-freezing heat transfer solution. For more information, see the instructions for
VALLOX VKL connections.
