Honeywell EkoFlush-K572 User's Operating Manual page 8

At the beginning of the flushing process, the unit automatically evacuates the circuit to clean
from the air, then automatically fills it with the solvent SOLSTICE
PLEASE NOTE
For circuits with more sections, the following steps are recommended:
As soon as the sight glass (Picture 4 - Pos.6) is filled with the liquid, close the valve on the
-
hose connected to the outlet marked "OUT" (on the left in picture 3).
The inlet sight glass (Picture 4 - Pos.7) enables the control of the filling of the complete
-
system to flush with the solvent SOLSTICE
When the liquid stops to flow in the inlet sight glass (Picture 4 - Pos.7), the circuit is
-
completely filled and it is possible to open the valve on the outlet hose marked "OUT" (blue,
on the left side of the picture).
The flushing procedure goes on automatically.
-
With simple circuits, the instructions above can be omitted.
7.3 The size of the solvent cylinder needs to be adapted to the size of the circuit to be flushed.
Please consult your local supplier for recommendations on the most suitable cylinders for your
flushing operations.
For best performance, the optimal internal diameter (Dn) of the circuits to flush should range
from 8 to 20 mm.
7.4 When the filter of the Outlet sight glass (Picture
slows down or practically stops (the pressure on the low pressure gauge - Picture 4 - Pos. 16 is
increasing slower than normal or it doesn´t increase at all), please follow these instructions:
- Close the valve on the hose connected with the "OUT" outlet (Picture 4, on the left, in blue),
- Let the unit run until the pressure on the low pressure gauge (Picture 4 - Pos. 16) reaches 0
bar (equal to 1 bar of absolute pressure).
- Turn off the unit using the Main Switch (Picture 4 - pos. 31)
- Wait for several minutes. The pressure on the low pressure gauge (Picture 4 – Pos. 16)
should increase.
- If the pressure increases over 0 bar (1 bar of absolute pressure), repeat the process (turn on
the unit and wait for the pressure to drop).
- When the pressure does not increase after having turned off the unit, you can dismantle the
sight glass (Picture 4 – Pos.6) and clean the filter.
Using the external P48 Filter prevents the Sight Glass filter to accumulate dirt.
It's important to follow the instructions here above to prevent injuries when disconnecting it
from the EkoFlush unit.
The unit must be turned off while dismantling the sight glass or the P48 filter. At the
same time, the valve of the hose on the outlet marked "OUT" (Picture 5 – left side – in
blue) must be closed!!!
