| IF HAVING ANY PROBLEMS WITH ISOLOK SAMPLER COMPONENTS... First, consult your instruction manual and drawings. If Bulletins or Drawings are missing, request replacements from the Factory. A complete manual and drawings are necessary to correctly service your sampling equipment and also provides a list of replaceable parts along with product illustration. Contacting the Factory: SENTRY EQUIPMENT CORP Phone: 262-567-7256 Fax: 262-567-4523 E-mail: sales@sentry-equip.com IF SAMPLER LEAKS PRODUCT OR AIR OUT BOTTOM PORTS... A thorough inspection is required. Replace worn seals; also, check recently replaced seals against drawings for correct installation If sampler continues to leak, replace other worn sampler parts, such as the body, head, barrel or plunger If problems continue, contact Factory. IF SAMPLER LEAKS PRODUCT AT PIPE CONNECTION... Check installation for mis-alignment. Replace locknut fastener if a threaded installation and add commercial grade Teflon tape when re-installing. If Tri-Clamp (TC) or Instrument Hub installation, check clamp/gasket (TC) or O-ring/Fasteners (IH) attaching sampler to line adapter. Replace seals if they are damaged or show signs of chemical attack If problems continue, contact Factory. IF SAMPLE DISCHARGE IS DECREASING... Check sample spool cavity for buildup. If buildup is a problem, add flush or air eject provision to sampler body Check nose of sampler for buildup. If buildup is a problem on nose of sampler (and pipe wall interior), remove body from line frequently and clean using plant procedures. If problems continue, contact Factory. IF SAMPLER WILL NOT OPERATE... Check power source and air connections. Connect as required. Check air lines for proper connection. Plunger must dwell retracted Connection lines backwards will cause sampler to dwell (pause) extended into process line. Check for air bind. Depending on density of product sampled, this problem can sometimes be resolved by opening a top port on sampler If problem continues, contact Factory. Check sampler operating air pressure and process line pressures. Operating air pressure must be sufficient fo move plunger against process pressure. Problem may be solved by increasing or decreasing air to sampler or relocating sampler. |
