(3) Disconnect the lead wires from the 3 reactors. (Photo 12)
(4) Remove the reactors from the unit (4 screws 4x10 on each
reactor).
13. How to remove the brine pump
(1) Pull out the module unit assy. (Refer to Procedure 11.)
(2) Remove the 8 Hex screws 5×12 from A to H of the module
unit assy to remove the module unit front . (Photo 13-1).
(3) Remove the module box top and the module box side R
from the module unit assy (13 screws 4x10). (Figure 11-5-
1)
(4) Disconnect the relay connector of brine pump.
(5) Remove the rubber mount, band C and band H. (Figure
13-1)
(6) Remove the flexible pipe (brine in) from the brine pump (the
fastener and the O-ring on the flexible pipe side). (Figure
13-1)
(7) Remove the TH32 lead wire. (Figure 13-2) (If the pipe
cover and the tape cannot be reused after removing TH32,
obtain them locally.)
(8) Release the lead wires from the clamps on the brine pump
base. (Figure 13-2)
(9) Remove the brine pump assy and the pipe BPUMP
BPHEX together (the fastener and the O-ring on the
P-HEX side, 2 screws 4x10 ).
(10) Remove pipe BPUMP BPHEX from the brine pump. (The
fastener and the O-ring on the brine pump side) (Figure
13-2)
(11) Remove the brine pump from the brine pump base (4
