Healy Systems, Inc. – the innovative leader of Stage II vapor recovery equipment
Vapor ready dispensers will require a Healy Systems adaptor to make the hose
threads compatible with other Healy Systems equipment. Install following
instructions packed with the adaptor. Various adaptors and pigtails are available,
depending on how the dispenser is configured: M34 metric (Healy designation F3 or
S3) or balance ready (Healy designation S4).
Healy Vapor Recovery Hoses are available in various lengths to satisfy local
ordinances and still provide “far side” fueling capability. Install these following
instructions contained on the shipping box.
Breakaways are required: Install either Model 8701-VV breakaway or Model 807
swivel breakaway; install using the instructions supplied with the unit.
The Healy Systems nozzle Model 900 (EVR) is the only nozzle necessary to complete
the upgrade.
Check to be sure the nozzle hanger is mounted in the highest position.
Be sure to check for proper fit in the nozzle holster and that the nozzle can be locked
in the off position. Also, be sure that when the nozzle is locked, that the dispenser
can not be activated from the locked position.
14. VP1000 THEORY OF OPERATION
The Healy Systems VP1000 is a self-contained rotary vane pump, designed for gasoline vapor
recovery utilizing various parts of the Healy System Vapor Recovery product line. It is intended
for use by either OEM dispenser/pump manufacturers or as an after market add-on to make
existing equipment compatible with Healy System technology. In order to convert to ‘others’
equipment, an electronic interface is required to adapt the targeted pump/dispenser to the new
vapor recovery equipment. The interface senses when authorization to dispense has been
given and sends signals to the motor to operate at a low speed for one hose, or a higher speed
for two hoses. It also functions to shut off the pump/dispenser if it senses that the vapor
pumpis not operating properly. The vacuum is regulated at a level sufficient to clear liquid
gasoline from the vapor path in MPD applications. The actual amount of vapors withdrawn is
controlled by the Healy nozzle, itself, in response to the liquid gasoline flow rate.
