Design ambient temperature range “Ta” Unless differently agreed with the customer, can be: -20°C ≤ Ta ≤ +40°C: standard temperature range for all type of pumps 5.0 Theory of Operation The PULSAlarm® leak detection system utilizes a two-layer PTFE diaphragm, coupled to the PULSAlarm®... - Page 9 The enclosure is labeled with applicable safety agency ratings for hazardous area installation. Since the switch is of the mechanical contact type, it can never qualify as non-sparking (non-incendive, or “M”) for occasional and short-term hazardous area use. Protection must be provided by the enclosure. In North America installations, the external supplemental ground is not to be used.

Thin oils such as silicone oil or mineral oil can also be used. Liquids of higher viscosity will extend the time required to properly prime the system. Thinner liquids will allow for faster setup. Pulsafeeder supplies low viscosity silicone oil standardly. - Page 14 System identification is noted on the switch cover nameplate, and on your Pulsa Series pump nameplate. The barrier fluid used to prime the system will vary with the application. The fluid selection must be compatible with the materials of construction used in the diaphragm and detection assembly.
- Page 15 used to pull the barrier fluid into the system. 6. Open the bottle of barrier fluid and run the tubing on the inlet side so the end near the bottom. Try to hold the bottle so that the bottom is at the same level as the inlet side fitting.
- Page 16 another). Refer to the Pump manual for further instruction. 16. If the pump is not already hydraulically primed, re-prime it now using the procedure found in the Pump Operating Manual. If the diaphragm was never removed, this step should not be necessary. If a new diaphragm is being installed, the pump will need to be re-primed.
