Note: Values in the tables apply to external static pressure 100 Pa. Different pressure requirements
may result in a different situation. If needed, the detailed initial and final pressure loss data of the
filters are available on request from the supplier of the unit.
Make sure that the position of the label makes it possible to regularly inspect the values recorded.
Unscrew the rotating knob as much as possible to set zero on the scale (the bottom knob
identified by - +), then screw it back by approximately two full turns to have leeway to make
settings in both directions.
Unscrew the FILL plug (the top knob) and keep filling the machine with measuring liquid (included
in delivery) until the liquid is visible near the zero mark on the scale. Use the bottom knob to set
the value on the scale precisely to zero. Screw the top filling plug in.
After installing the manometers do not tilt the machine or the door (if they are installed on the
door). Measurement liquid might leak out.

Installing hot water heating coil
During the mechanical installation of the hot water air heater follow the manual supplied with this
optional accessory.
The following rules must be adhered to during the installation of the heater:
The maximum permitted temperature of heating medium is 110 °C and operational positive
pressure up to 1.0 MPa.
For the proper operation of the control set of the hot water heater the heating system must be
fitted with a circulation pump of suitable power that will fully cover its pressure losses. The pump,
which is supplied with the control set, is designed solely to cover the pressure losses of the water
heater!
If the unit is not equipped with a shut-off damper on outdoor air inlet e1, a tight shut-off damper
must be installed in the duct upstream the unit (a type with a servo drive with emergency stop, that
is, that automatically shuts in the event of a power outage).
The heating system must be equipped with a sludge filter in the inlet into the unit.
A temperature sensor must be installed into the air duct to provide for anti-freeze protection of the
hot water heating coil. The sensor is to be installed behind the hot water heating coil in the
direction of air flow. Please follow the instructions in the guide enclosed to the temperature sensor
TA when installing the sensor.
