Warranty Information
Solenoid valves and all other products manufactured by Spartan are warranted by Spartan to be free from defects in material and work-
manship for a period of 1 year from the date of purchase. Spartan's obligation under this warranty is limited to repair or replacement of the
defective product or refund of the purchase price paid solely at the discretion of Spartan and provided such defective product is returned to
Spartan freight prepaid and upon examination by Spartan such product is found defective. This warranty shall be void in the event that the
product has been subject to misuse, misapplication, improper maintenance, modication or tampering. This warranty is expressed in lieu
of all other warranties, expressed or implied from Spartan Scientic, Inc., representatives or employees.
Excessive use of pipe sealant can cause clogging and leakage. Please follow ASME standards for applying pipe sealant and tape. Do
not use media, voltage or pressures other than that recommended by Spartan Scientic Inc. as valve malfunction could result. Misuse or
misapplication of Spartan solenoid valves could cause serious bodily injury or property damage.

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. Connecttheunit’sinletporttothecondensateline;followtheowarrowontheCRDV/S,(itisadvisabletoinstallaballvalve
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 Scientic 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.

High Flow Mode:
If, during normal mode, there is a high production of condensate, the CRDV/S function will change to accommodate the
increasedneedtoremovewaterfromthesystem.Asinnormalmode,theCRDV/Sremainsdormant,sensingforcondensate.
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

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
