Assemblies are shipped without drain line

Assembly instructions:
1. Determine the desired
fl
ow rate. Select a combination of V3190-XXX’s to arrive at the desired
fl
ow rate.
2. Using a drill or punch remove the desired knockout(s) in V3766. Each V3766 retainer contains two types of knock
outs. The larger knockouts are removed to install a DLFC. If two V3766 retainers are needed remove the smaller
diameter knockout that lines up with the DLFC installed in the other retainer. One or two V3766 retainers may be
used. When using one V3766 retainer V3190-XXX must be installed in the center hole. When using two V3766
retainers a V3190-XXX must be installed in the center hole of one of the retainers and the center hole on the other
retainer must remain open.
3. Smooth hole(s).
4. Install appropriate size(s) of drain line
fl
ow control washers. Pay close attention to proper DLFC orientation.
5. Assemble. Each V3766 retainer must have a V3769 o-ring installed. One each of the V3767 retainer cover and V3768
retainer ring must be used whether one or two V3766 retainers are used. The positioning of the V3768 retainer ring
varies depending on the number of V3766 retainer(s) used. Properly orientate the V3766(s) in the direction of
fl
ow.
6. Properly orientate the complete assembly in the direction of
fl
ow. Inlet and outlet threads are 3”.
