Tubing
Route the regulator tubing so any condensation in
the air lines will not run into the control. Allow slack
in the regulator tube leads so that they can be
pinched for maintenance and diagnostic purposes,
Each regulator tubing lead may be used to supply air
to two nipple line regulator inlets. This will assure
enough flush water volume per line to move air and
sediment down the nipple lines and out. Run each air
supply tube across the ceiling and down the water
supply hose to each of the regulators, attaching it to
the provided hose barb on the bottom of each
regulator,
Warming the end of the
tubing will aid in installation.
Caution: Over-Heating of tube end can cause
distortion and leaking.
Compressed Air Supply
Air compressor (not supplied) guidelines to operate the system.
• All air compressors must have a minimum rating to run 4
times per hour for 5 minutes each run.
• One (1) PDS™ Control - 2 gallon minimum recommended
air supply tank.
• Two (2) - four (4) PDS™ Controls - 5 gallon minimum
recommended air supply tank.
• Five (5) - six (6) PDS™ Controls - 10 gallon minimum
recommended air supply tank.
• Air regulator with 1/4" fitting and has adjustable range of
0-125 psi
• Approved air regulators:
• Grainger Industrial Supply Part number 4ZMO8
• Grainger Industrial Supply Part number 4ZMO6
• NAPA Part number 90-725
Note: The PDS Control operates at 12 psi [68.95 kPa]. Most air regulators supplied with air
compressors will not effectively regulate air pressure at 12 psi [68.95 kPa]. Chore-Time
recommends using one of the approved air regulators listed above.
BEFORE
connecting the compressed air supply to the control, turn the red adjustment knob clockwise (Decrease)
until the knob stops turning,
BEFORE
connecting the compressed air supply to the control,
the compressed air supplied to the PDS™
control, must be regulated between
6 and 12 psi [41.37 and 68.95 kPa]
.
Failure to do this will result in
damage to the gauges and possibly other components.
After the air supplied from the compressor is confirmed
to be between 6 and 12 psi
[41.37 and 68.95 kPa]
, connect the air supply to the incoming pressure line on the PDS
The PDS Control has an air pressure gauge to monitor the incoming air
pressure. Under normal operating conditions, this gauge should show
between 6 and 12 psi
[41.37 and 68.95 kPa]
of air pressure.
