RECEIVER DRAIN TIMER
OPERATION
The Drain Timer is designed for trouble-free
draining of un-wanted accumulations of
condensate. The timer module initiates a drain
cycle by energizing the valve coil that opens
the valve and allows the condensate to drain.
At the end of the cycle, the coil is de-
energized and the valve is spring-returned to
the closed position. At the beginning of drain
cycle the ON light illuminates and the OFF
light turns off. The lights switch at the end of a
timer cycle.
First, when power is applied to the timer, the
timer will immediately put power to the valve
for the amount of time indicated by the setting
of the ON TIME. Removing and reapplying
power will again actuate the timing cycle.
Second, pushing the test button located on the
front panel will actuate the valve for as long as
the button is depressed.
Third, once the timer is plugged in the timing cycle will begin. The valve will be actuated at the interval of time that
is indicated by the setting of the knob for the Off Time.
TESTING THE DRAIN TIMER
COMPRESSED AIR CAN BE DANGEROUS. Be sure the pressure vessel is depressurized prior
to any attempt to install or remove the Drain Timer. DO NOT REMOVE the power cord or timer
from the valve while the Drain Timer is plugged in. If the drain does not seem to be working
properly, contact your distributor. Any attempt to repair the drain without authorization will
VOID WARRANTY.
1. Fully drain the vessel by opening an auxiliary gate valve or push the test button on the timer. When all of the
condensate has drained, set the OFF TIME to the maximum 45 minute setting and the ON TIME to the
maximum 10 seconds.
2. Remove the valve guard strainer and inspect for debris and damage. Clean or replace as necessary.
3. Return prior to the time 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 1 & 2.
4. 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. 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.
