INSTALLATION INSTRUCTIONS (see illustrations following):
New installations:
For top and side mount models:
Drill a 3/4" diameter hole through one wall of the pipe.
For vertical mount models:
Drill a 13/16" diameter hole through one wall of the pipe.
The hole should be in centered in the pipe.
See chart for minimum location dimensions of the flowmeter from any pipe turns or
internal pipe obstructions.
For replacement flowmeters:
Make sure the mounting hole in the pipe is 3/4" diameter for top or side mount models
or 13/16" diameter for vertical models. Re-drilling may be necessary.
For all models except vertical mount on PVC pipe, the black rubber gasket is
mounted on the stem of the flowmeter.
For vertical mount on PVC pipe confirm that both Gaskets are fully inserted into both
sides of the Curved Spacer before attaching assembly to pipe. Rotate Curved Spacer
to align curved face of Spacer to pipe.
Insert the stem into the pipe hole. Strap the flowmeter in place using the supplied hose
clamps. Use double-length clamps, (2 clamps threaded together) on large diameter
pipe (4", 6", and 8" flowmeters). Flowmeter water tubes should be as vertical as
possible.
Read the flow on the scale of the side plate at the center of the ball.
Note: Scale readings are based on Schedule 40 PVC and Type M copper pipe.
If the inside diameter of pipe is different (having other inside diameters) the scales will
not read correctly.
Full Range Accuracy is ± 10% when installed according to instructions.
Flowmeters are designed to withstand temperatures up to 200°F.
Flowmeter dimensions: 9" High x 4" Wide x 1.5" Deep.
