Dwyer SVT - Manual (Page 4)

MAINTENANCE
Warning: To prevent the possibility of death, serious injury or
property damage, turn off electrical power, depressurize system
and unit before servicing.
The SVT/SVTE should be cleaned periodically. The amount of
time between cleanings depends on the application. Preventive
maintenance includes keeping media clean of material and oil
free, and periodic testing to insure proper operation and to look
for wear or damage.
Warranty
Upon final installation the series SVT Solenoid Valve Enclosure
with Timer and the series SVTE Expansion Module, no routine
maintenance is required. A periodic check of the system
calibration is recommended. The series SVT and SVTE are not
field serviceable and should be returned if repair is needed (field
repair should not be attempted and may void warranty). Be sure
to include a brief description of the problem plus any relevant
application notes. Contact customer service to receive a returns
goods authorization number before shipping.
