INSTALLATION INSTRUCTIONS FOR THE
POSI DRAIN®
1. Wire in parallel
2. Maximum of four valves per controller.
DIAGRAM 2 - WIRING MULTI-VALVE DRAIN
INTRODUCTION
The POSI VALVE is designed for trouble-free draining of
unwanted accumulations of condensate and other foreign
matter from compressed air systems.
TESTING THE POSI-DRAIN
1. Plug the POSI-DRAIN7into a 115V 60HZ grounded socket.
2. Set in "TEST" position. The POSI-DRAIN will cycle on (1-
15 seconds as set) and off for 5 seconds in the "TEST"
position.
3. Removing and reapplying the power will cause the drain
valve to open for the set ON TIME (1-15 seconds).
INSTALLATION and ADJUSTMENTS
1. USE CAUTION: COMPRESSED AIR CAN BE DANGER-
OUS. Be sure the pressure vessel on which the drain will be
installed is depressurized prior to any attempt to install the
POSI-DRAIN. DO NOT REMOVE the cover of the drain while
it is plugged in. If the drain does not seem to be working
properly, contact your distributor for return authorization. Any
attempt to repair the drain without authorization will VOID
WARRANTY.
2. The POSI-DRAIN drain valve must be installed so that the
flow of the condensate is in the same direction as the arrow on
the valve. Improper installation will cause the valve to leak and
could damage the valve seat. For optimum life and perfor-
mance, the drain or valve should be mounted in a vertical and
upright position. This would reduce the possibility of any
foreign matter accumulating in the core tube area. The drain
should be installed as close to source as possible.
3. Fully drain the vessel by opening an auxiliary gate valve (see
Diagram 1) or switch the POSI-DRAIN to test as described
above (Testing the POSI-DRAIN)
4. When all of the condensate has drained, set the OFF TIME
to the maximum 50 minute setting and the ON TIME to the
maximum 15 seconds.
5. Return prior to the time that the drain is expected to open
and check to see how long it takes for the valve to exhaust the
liquid. If at the end of the drain open period all the liquid has
not been expelled, adjust the OFF TIME downward and repeat
steps 3, 4, and 5.
6. Set the ON TIME equal to the amount of time it takes to drain
the vessel. We suggest increasing the time by 20% to
compensate for small fluctuations in air system usage or
climatic changes.
7. The drain should be checked periodically to ensure a proper
setting was achieved. In climates with large changes in
humidity, the drain should be checked and reset accordingly.
WARRANTY
The POSI-DRAIN and valves are warranted to be free from
defects in workmanship and materials for a period of one year
from the date of shipment. The liability of the manufacturer
and/or distributor is limited to repair or replacement of the drain
at its option. In no event shall the manufacturer and/or
distributor be liable for special or consequential damages or for
any delay in performance of this warranty.
