NOTES:
1. Use two all-stainless hose clamps per connection. One set of 1” insert barb x
Double O-ring adapter fittings is included with AHK5EC hose kit.
2. One set of cam adapters required for connection to flush cart hoses. Cam
connectors should be left with the installed Flow Controller for future service.
Most flush carts will have female cam fittings that will mate to these fittings.
3. Adapters from 1” MPT to copper sweat or PVC glue provided by others.

Piping Installation
The Flow Controller features Double O-ring fittings for
flexible and easy installation. Table 1 illustrates the
connection options available for Flow Controllers with
polystyrene cabinets. Avoid using 3/4” [19.1mm] piping
on flows greater than 6 gpm [0.38 l/s]. Pressure drop in
piping systems should be calculated to insure adequate
flow through unit. All piping should be properly insulated
with closed cell insulation of 1/2” [12.7 mm] wall thickness.
Table 2 shows the insulation requirements for typical piping
materials. Piping insulation should be glued and sealed
to prevent condensation using closed cell insulation glue.
The swivel connectors on the Flow Controller are designed
to be hand tightened only. Connections between the Flow
Controller and adapters are sealed with double o-rings
fittings shown in figure 4.
Loop side piping is typically polyethylene piping directly
into the Flow Controller. Connection to the Flow Controller
