INSTALLATION
Please read before installing this equipment. Failure to do so may void your
warranty.
Installation
The 801 and 802 ow meters give the best accuracy when there is a smooth,
unobstructed ow through it. To minimize turbulence, there should be at least
12″/30cm of straight plumbing upstream from the ow meter and at least
6″/15cm of straight plumbing downstream from the ow meter. Mount the ow
meter in a location that physically protects it from damage and allows liquid to
drain away after the sprayer is ushed and secured at the end of the operating
day. A straight, vertical section of the main boom supply line is the ideal location
for the ow meter.
Keep the ow meter from lying in a low section of the sprayer plumbing.
This is particularly important in cold weather when water might freeze in the
ow meter and cause damage to the unit. It is also important when applying
chemical suspensions which may settle out and stall the ow meter turbine if
they cannot drain away.
Before installing the ow meter insert, make sure there are no obstructions in
the insert cavity. Clearance at the bottom of the cavity is very close and over
compressing of foreign material in the cavity can cause damage to the ow
meter body. For 801, turn the insert locking collar until it is hand tight. For 802
install the ow meter insert until the pin openings are aligned.
Prior to each day’s spraying, the ow meter should be inspected to ensure there
are no leaks around the attachment ttings. At the end of the day, care should
be taken to thoroughly ush the ow meter with clean water.
Make sure no water or sediment is trapped in the flow meter
The impeller type ow meters supplied by TeeJet Technologies are inherently
rugged. However, continued use over time will eventually wear the internal
bearings and shafts until the meter becomes inaccurate. Replacement kits are
available to repair the ow meters. Contact your TeeJet Technologies dealer for
these parts.
