1� Remove the two end fittings from the flow meter� Lubricate the O-rings and install the
fittings onto the flow meter�
LIQUID PIPE SEALANTS, PVC/CPVC PRIMERS AND PVC/CPVC CEMENTS CONTAIN
SOLVENTS THAT ARE NOT COMPATIBLE WITH POLYSULFONE PLASTIC. ALLOWING
LIQUID PIPE SEALANTS TO CONTACT THE PLASTIC FLOW METER WILL RESULT IN
WEAKENING OF THE FLOW METER BODY AND POTENTIALLY CAUSE FRACTURING
UNDER PRESSURE.
2� Prepare the flow meter PVC fittings and PVC pipe couplings with PVC cleaner/solvent�
3� Apply a thin layer of PVC glue to the PVC flow meter fittings� Orient the meter during
curing so that excessive glue will not run into or onto the flow meter� Connect all PVC
glue joints by inserting the pipes fully into their mating components and twisting 1/8
turn to provide adhesion� Allow sufficient drying time�
4� Using the method outlined in steps 2 and 3, apply half of the PVC union to the flow
meter outlet fitting�
5� Install the other half of the PVC pipe union to the outlet pipe�
6� Make sure the flow direction arrow on the flow meter corresponds with the system
flow direction� See
Figure 4 on page 9
� Lubricate the union O-ring and connect the
union together�
OTEE:
N
Piping should be supported and aligned properly to avoid placing stress
on the flow meter body�
7� Slide the limit indicators to point to appropriate positions on the flow meter scale� To
remove the limit indicators, slide them fully toward the flow meter outlet
