MAINTENANCE
When using the SSSD models it is strongly recommended
to blow-off accumulation in the strainer a day or two after
the system has been installed. A periodic blow-off or
cleaning of the strainer should be instituted.
If trap fails, close isolation valves and remove cap using a
suitable spanner. Dirt or sediment on the disc or body
seating will cause abnormal operation. To clean these
parts use a soft cloth and solvent. DO NOT WIRE BRUSH
OR USE ANY ROUGH IMPLEMENT. Reassemble the
unit with the groove in the disc facing down. Apply
antiseize compound on the cap threads. Avoid getting
compound on the disc or body seating surfaces. See the
torque table to the right for recommended torque values.
For the SSST option a peroidic cleaning of the strainer
should be instituted. Unscrew the strainer plug using a
suitable spanner, withdraw the screen and clean it or
replace it if damaged. To reassemble, reverse the
procedure. A periodic check of system calibration is
recommended. The Series TDST is 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 return goods authorization number before
shipping.
