7. Device flushing procedure
7.1
Check the hose interconnection (see capture 6).
7.2 Open all valves on the refrigerant cylinder and hoses as well.
After ending of the complete flushing procedure is the situation identic!
After switching on and starting up the unit automatically evacuates the flushed equipment, the
next automatically step fills the flushed equipment with the solvent liquid.
For flushing equipment with more sections are recommended following steps:
As soon as the sight glass (Pos.6) is filled with the liquid, close the hose valve on "OUT"
marked outlet.
The sight glass Pos.7 enables the control of filling of the complete system with the solvent
SOLSTICE
®
PF. Until the liquid stops to flow in the sight glass (Pos.7), the complete flushed
system is filled and it is possible to open the hose valve on "OUT" marked outlet. Further runs
the procedure automatically.
At simple equipment it can be omitted.
7.3 Size of the refrigerant cylinder is to be adapted to the size of the flushed device (alternative
refrigerant cylinders of volume 12,5 litres or 27,5 litres). Maximum recommended volume of the
flushed component can be 14 litres by using a refrigerant cylinder with a total volume of 27,5
litres. If the recommended volume is 3 litres, a refrigerant cylinder with a total volume of 12.5
litres should be used.
Permissible filling of a 12,5 litre refrigerant cylinder using SOLSTICE
®
PF-C is 11,0 kg.
Permissible filling of a 27,5 litre refrigerant cylinder using SOLSTICE
®
PF-C -TZ is 24 kg.
Recommended range of the line inside diameter (Dn) of the flushed components is 8 to 20 mm.
7.4 When the filter of a sight glass (pos. 6) is fouled and the current process slows down or stops
practically (the pressure on low pressure gauge pos. 16 is slowly increasing compared to
normal operation or it doesn´t increase), act upon following instructions:
Close the valve on the hose connected on outlet, let the unit to run up until the pressure on the
low pressure gauge (pos. 16) doesn´t drop under 0 bar (1 bar of absolute pressure).
Then turn off the unit (pos. 31), wait for several minutes, if the pressure does not increase on
the low pressure gauge. Provided the pressure increases over 0 bar (1 bar of absolute
pressure), repeat the process (turn on the unit and wait for the pressure drop). When the
pressure does not increase after the turn-off of the unit, you can dismantle the sight glass and
clean the filter.
The unit has to be turned off while dismantling of the sight glass, herewith the valve
(pos. 21) is closed, and at the same time the valve of the hose on the outlet (pos.35) has
to be closed!!!
