5.9 Installation, connecting and filling of liquid manometers (optional accessory)
●
Liquid manometers (supplied separately) are used for measuring the pressure loss of air filters. During installation follow the
visual instructions supplied. After installation level the manometers horizontally.
●
Connect the manometers to collection points on the unit´s surface using tubes. Connect the tube to the top of the manometer
and run it to the plastic bushing on the unit´s surface. The tube must always connect two matching connection points identified
by symbols "+" / "F+" and "-" / "F-" (cannot be combined). Make sure that tubes from just one filter are connected to the
manometer.
●
Attach the relevant label near each manometer. Fill out the boxes with the filter grade and record the flow rates and pressure
losses of the clean filter (initial pressure loss) and when clogged (final pressure loss) using data from the table below. The values
must be adjusted on the basis of actual air flow rates through the unit. The label without information completed is included.

Note: Values in the tables apply to external static pressure 200 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 labels makes it possible to regularly inspect the recorded values.
●
Unscrew the rotating knob as much as possible to zero on the scale (the bottom knob identified by - +), then screw it back by
approximately two full turns ensuring 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 to precisely zero. Screw the top filling
plug in.
●
ATTENTION: After installing the manometers do not tilt the machine or the door (if they are installed on the door).
Measurement liquid may leak out.
5.10 Installation and connecting of the hot water air heater (optional accessory)
●
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 solely designed to
cover the pressure losses of the water heater!
●
If the unit is not equipped with a shut-off damper on the outdoor air inlet e1, a tight shut-off damper must be installed in the
upstream duct of the unit (a type with a servo drive and emergency stop, i.e. which automatically shuts off in the event of a
power cut).
●
The inlet of the heating system into the unit must be equipped with a sludge filter.
5.11 Installation and connecting of the control set of the hot water air heater (optional
accessory)
●
During the mechanical installation and connection of the control set of the hot water air heater follow the manual supplied.
5.12 Installation and connecting of shut-off dampers e1, i1 (optional accessory)
●
During the mechanical installation and connection of the servo drive of shut-off dampers follow the manual supplied.
