10. Exchange of SOLSTICE
®
PF-C solvent
The programme of the EkoFlush unit is according to the recommendation of company Honeywell set
so, that after 20 flushing procedures (not only cycles) the unit informs SOLSTICE
®
PF-C solvent
should be changed showing symbols – 3 horizontal blinking lines on a display.
The company Honeywell recommends to change the flushing solvent SOLSTICE
®
PF-C after flushing
20 A/C or refrigerating circuits. The real efficiency abatement of the flushing solvent depends on the
type and level of fouling of the cleaned equipment.
The number of remaining flushing procedures appears on the display three times after turn on the
main switch.
After SOLSTICE
®
PF-C solvent is changed the report – 3 horizontal blinking lines – has to be
cancelled with following step:
- turn on the main switch
-
pressing simultaneously PB4 and PB5
Provided the flushing unit is used only for distillation of used SOLSTICE
®
PF-C (see chapter 11), this
indication is unimportant, but it is necessary to cancel it by a described method. Provided the report is
not cancelled trough described procedure, it appears always after machine switch on before the new
flushing procedure starts and for continuing of programme setting is necessary to press
simultaneously PB2 and PB3.
11. Oil Change, Adding Oil
The oil change procedure: open the sight glass and drain off the oil from the Unit into a suitable
vessel.
During filling, it is necessary to place a sufficient volume of oil in a suitable vessel under the oil inlet
(pos. 33), so that the hose fitted to the valve aperture reaches the bottom of the vessel. Then follow
the procedure stated below.
Procedure:

11.2 Connect the inlet (IN) and the outlet (OUT) with a hose with a ball valve and close the valve.
11.3 Turn the main switch on.
11.4 Press PB 4 button and wait for 20s until LED 6 stops blinking.
11.5 Press PB 4 again – the compressor will turn on and the oil from the vessel will be sucked into the
device.
11.6 Once the vessel is empty, press PB 5 – “END”.
11.7 Close the valve pos. 33, disconnect the hose between the device’s inlet and outlet, and turn the
