Pump units are installed in the
back of the car.
There is a 3-way valve that
leads turbine air flow out in
normal use. However if you
pull the button inside the car
the air flow will be blown
inside the car. This can be done
if some over pressure is needed
inside the car.
The pump is installed inside the
pump unit.
On the back of pump unit there
are connectors for Power and
Pump Control and Fuse.
Pump is protected by integrated
Heat sensor. So if pump gets
too hot it will automatically
stop pump and when cooled
it will be again operational.
Life time of pump is about
20.000 hours.

MEASURING UNIT
TOP:
Left sampling system
a) Panel meter
- display
- pressure difference, Pascal (A1)
- volume flow, m3/h (A2)
- total air volume, m3/h (A3)
- total time, hh:mm:ss (A4)
You can scroll different channels during
sampling.
b) Reset
- Reset panel meter memory before
every new sampling
c) Flow control
- Turn CW to enrease air flow
- Turn CCW to 0 to STOP sampling
LOWER PANEL METER AND CONTROLS
FOR RIGHT SIDE SAMPLING SYSTEMS
FUSE
- automatic fuse
If blown check what caused problem
and reset by pushing in.
MAIN SWITCH
Turns Mains Power to Measuring Unit
230VAC/50Hz

HOW-TO
1. Turn mains Power ON
2. RESET both panel meters
by pushing RESET button
once.
3. Turn flow control CW
to START sampling
You can choose from 1-3
different flow speeds.
4. After you have sampled
long enough, turn Flow
Control CCW to 0 to
STOP sampling.
5. Read panelmeter values
A3= Total volume in m3
RESET button
Flow Control
Automatic Fuse
Mains Power Switch
6. A4= Total time in hh:mm:ss
AND AGAIN:
1. Change filter
2. RESET panel meters
3. Start sampling
4. Stop sampling
5. Read panel meter values
ATTENTION!
Pump has integrated thermostat
so that if it heats too much it
will shut down. When it has
cooled it will start automatically.
