5.0 FEATURES
5.1 SOLENOID VALVE - The integrated solenoid valve isolates on shut down or on power failure,
preserves vacuum integrity of system and eliminates oil returning or contamination.
5.2 IGNITION PROTECTED SWITCH and circuit breaker for use with A2L gases/refrigerant.
5.3 INTEGRATED DEMISTER - The dual stage oil mist filter effectively filters oil mist, reducing
pollution and oil consumption.
5.4 FORCED OIL LUBRICATION - The purpose is to provide lubrication to the bearings and seals
enhancing the life of the vacuum pump.
5.5 INTEGRATED VACUUM GAUGE (optional).
5.6 GAS BALLAST - The function is to allow condensable vapors (i.e. water) to be discharged
through the pump to atmosphere instead of accumulating in oil reservoir.
5.7 WIDE BODY - Ensures maximum stability by preventing tipping over.
5.8 FAN offers positive air-cooling that channels air over motor and vacuum pump casing.
This not only prevents overheating but maintains the temperature at a controlled level.
5.9 INTEGRATED MOTOR - is high torque for low temperature starts.
5.10 INTEGRATED SPARKPROOF POWER SWITCH, LEAD AND CIRCUIT BREAKER.
5.11 COMPACT, LIGHT WEIGHT AND A LOW NOISE PUMP.
6.0 START-UP PROCEDURE
THE BULLDOG A2L / DV IS SHIPPED WITHOUT OIL IN ITS RESERVOIR...
DO NOT START PUMP WITHOUT ADDING OIL!
6.1 Place pump on flat surface REMOVE Oil Filler cap.
6.2 Pour oil SLOWLY to avoid OVERFLOW AND SPILL. Fill up to the centre of the sight glass with
JAVAC approved LOW VISCOSITY OIL [Part No. VC2063 (1L) OR VS4015 (5L)].
6.3 NOTE: Oil level will rise when the pump warms up & reaches the operating temperature. Check
oil level when warm & adjust if required. DO NOT OVERFILL.
6.4 Remove cap the inlet ports.
6.5 Turn power switch ON.
6.6 Let the BULLDOG A2L / DV run for 10-20 minutes to reach operating temperature.
6.7 Turn power switch OFF and CONNECT to system.
PRIOR TO CONNECTING THE BULLDOG A2L / DV TO AN AC/R SYSTEM, REMOVAL OF
REFRIGERANT FROM THE SYSTEM IS NECESSARY; WE RECOMMEND THE JAVAC XTR-A2L
SPARK PROOF RECOVERY UNIT (XTRC2A2L) FOR THIS PURPOSE. DAMAGE TO THE PUMP
MAY OCCUR IF EVACUATION IS STARTED WHILE THE SYSTEM IS UNDER HIGH PRESSURE.
