as directed.
Item V01 – 2 Station Valve Block (44963D) may be substituted with:
Item Part Number Name Quantity
V01 44933D VALVE BLOCK ASSEM UC4-BC 2-STATION CC/LS VARIABLE RATE 1
The 44933D is a direct replacement for the 44963D. Both valve blocks function the same. The blocks
are identifiable by the filter cap shape and by the part number stamped on the side.
The A and B ports are opposite on each valve block so verify that the hoses are being connected to
the correct port. The raise lines always go to the “B” port and the lower lines go to the “A” port.
