For the flow and return connections fit the 1¼” union (TopGas
60,80) or 1½” union (TopGas 100,120) on the flexible pipe to
the extension pipe. Before fitting apply PTFE tape (or other
suitable thread sealing media). Tighten to ensure a good seal
is made.
See page 35 for the TopGas 60,80 or page 36 for TopGas
100,120 for pump and valve set connection instructions. Fit
the remaining side of the flexible pipe to the respective valve.
A gasket must be used at either end to ensure a water tight
seal. Tighten accordingly.
