Circuit Board Setting; Figure 5. Flow Control Washer - Cornelius IACS224 Installation Manual

2. There is flow washer in the inlet side of the float assembly that will control inlet eater pressure from 50/120
PSI (3.4/8.16 Bars). This will prevent float flutter. In low water pressure conditions, 20 PSI (1.37 Bars) or
less, the flow washer may have to be removed from the float assembly for proper fill volume.
Push the manual DUMP switch - allow dump action to drain the water pan. When you release the momentary
switch, the pump will stop and the float will return the water level back to its original setting and shut off the wa-
ter supply.
3. You have the option of selecting dump cycle intervals of:
S
every cycle
S
every 3rd cycle
S
every 7th cycle
Remember: The higher the mineral content in the water supply the more often it will be required to dump the
water and/or clean the product if proper water treatment is not used.

CIRCUIT BOARD SETTING

Figure 6 shows the setting of circuit board. There are dump cycle dip switch (S3) and curtain selection dip
switch (SW4) in the circuit board. Even though no water curtain equipped in IACS224 and IWCs224, "single cur-
tain connection" on SW4 need to be selected.
