INTRODUCTION
The SURE DRAIN is designed for trouble-free draining of
unwanted accumulations of condensate and other foreign
matter from compressed air systems.
TESTING THE SURE-DRAIN
1. Plug the SURE-DRAIN into a 115V 60HZ grounded
socket.
2. Set in "TEST" position. The SURE-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
SURE-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 SURE-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
performance, the drain or valve should be mounted in a
vertical and upright position. This would reduce the possibil-
ity 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 SURE-DRAIN to test as described
above (Testing the SURE-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 compen-
sate 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 SURE-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/

liable for special or consequential damages or for any delay in
performance of this warranty.
