1. The CRDV/S is an automatic device and will cycle with the presence of water at the inlet and one time initially to indicate
that it is working. It is important to make all pressure connections prior to making electrical connections as the CRDV/S
automatically cycles without warning.
2. Drain the tanks, dryers, coolers or any device that is the producer of the condensate of any water and air pressure prior to
CRDV/S installation.
3. It is necessary to mount the CRDV/S below the vessel it is draining, as the condensate is gravity fed to the inlet port of the
CRDV/S.
4. Connecttheunit’sinletporttothecondensateline;followtheowarrowontheCRDV/S,(itisadvisabletoinstallaballvalve
or ball valve strainer to facilitate future service of your CRDV/S).
5. Connect the exhaust port to an air-oil separator or equivalent device.
6. Connect the wall plug to a convenient wall connection and you are ready to go.
 NOTE: Spartan Scientic strongly recommends the use of a strainer prior to the inlet of the CRDV/S to lter out any
particulate. If no strainer is used particulate build up may occur causing a minor leak. To remedy this condition, it is necessary
to apply a sustained purge of 5 to 10 seconds to clear the debris.

Normal Mode:
WhentheCRDV/Sisrstconnectedtoelectricity,theunitgoesintoaoneminuteinitializationmodeduringwhichtheoverride
button is non-functional and the following sequence occurs:
L1LED=Power(grn)/Valve(yel)
L2LED=Detect(grn)/Alarm(yel)
L1red/grn L2red/grn @1Hz(chatterwarning) for10seconds.
L1red/grn L2off @10Hzandvalvechatters for2seconds
L1 grn L2 off Pause for 3 seconds
L1yel  L2off Valveon(shortvaporpurge) for1second
L1grn/red L2off @1Hz (sensorwarmup) for35seconds
L1 grn L2 off – unit ready for /use.
Aftertheinitializationmode,theunitwillimmediatelyenternormalmode.
Ascondensateisgenerated,thewaterandefuentfallsbygravitythroughthepipingtotheinletoftheCRDV/S.
AshortvaporpurgeoccurscontinuallytoinsurethereisnotrappedairinthelinestopreventwaterfromreachingtheCRDV/S.
The time interval between vapor purges is automatically adjusted based on the need and can vary between 2 minutes and 2 hours.
NothingelsehappensuntiltheCRDV/Ssolid-statesensorsensesthepresenceofcondensate.Atthattimetheelectronicssends
thesignaltoenergizethesolenoidvalve,whichopensandexhauststhecondensatefromthepneumaticsystem.Aftera1second
purgeintervalthevalvede-energizesandthesensornolongersenseswaterattheinletport.TheCRDV/Sthengoesdormantfor
aminimumof35secondsafterwhichtheunitwillstandreadytopurgecondensateagain,onlywhenitissensed.Ascondensate
once again builds up, the sensor senses the presence of condensate and the purge cycle continues.
High Flow Mode:
If, during normal mode, there is a high production of condensate, the CRDV/S function will change to accommodate the
increasedneedtoremovewaterfromthesystem.Asinnormalmode,theCRDV/Sremainsdormant,sensingforcondensate.
If there is a high amount of condensate at the inlet port, so much so that the 1 second purge will not remove it all from the port,
the CRDV/S “learns” and opens for a 2 second purge interval. The unit then goes into a 35 second wait cycle after which the
CRDV/S, if it continues to sense condensate, continues to re-cycle adding 1 second to the purge interval each time. The sensor
goes into alarm mode when the purge interval gets to 6 seconds. During alarm mode the CRDV/S repeats the purge cycle adding
1 second to the purge interval each time until the sensor stops sensing condensate. When the sensor runs free of condensate the
CRDV/S returns to normal mode. If during alarm mode the purge interval gets to 16 seconds, the unit will enter an emergency
shutdownmodetoconserveairandwillashbothLEDsata1Hzrateuntilpowerisremovedandreapplied.
Electrical and Manual Override:
The CRDV/S is equipped with both a manual override and an electrical override. The manual override is the green push button
found on the side of the valve at the back of the unit. Pressing this button allows for drainage of the condensate line without the
needforelectricity.Theelectricaloverrideisabuttonfoundatthefrontoftheunitwhichenergizesthesolenoidanddrainsthe
condensate line. Both overrides are momentary contact, spring return.
One 1 second purge cycle every 24 hours
Thereisone1secondpurge/chattercycleevery24hoursjusttoensurethatthecondensatelinesareclearandefuentisowing
to the CRDV/S.
