REGULATOR MAINTENANCE & SAFETY FEATURES
• Because the Shrinkfast UL ® approved regulator assembly is assembled and tested at the
factory to conform to UL ® Standard 144, any maintenance or repairs should be in
accordance with this listing as well as any other applicable regulations. Regulator parts
showing wear should be replaced as necessary. Contact your local distributor or
Shrinkfast directly for descriptions and part numbers.
IMPORTANT SAFETY FEATURE: Inside the POL fitting on the
Regulator Assembly there is a safety featured called the “Excess Flow Device”.
• This safety feature is designed to stop the flow of propane if the hose becomes
cut or detached from the regulator or heat tool during operation.
• The Excess Flow Device does not stop the propane flow 100%, but it does
reduce the flow so the user has time to get to the tank and shut off the propane
and prevent a dangerous situation from occurring.
How the Excess Flow Device Works:
• When the propane tank is first turned on the Excess Flow Device believes there
may be a downstream leak and temporarily closes the POL. The POL does not
stop the flow entirely, so there is enough propane entering the hose to begin
pressurizing the system.
