INSTALLATION WARNING: Improper installation may result in damage to the unit, personal injury or death. All persons operating the Yacht Pro Series system must read this manual completely and fully understand the procedures for system operation and the responsibilities of the operator to insure the safety of divers supplied with air from the system.
WARNING: Divers lives depend upon proper operation of the system. Brownie’s Third Lung highly recommends that all system operators take a System Training Course. PRE START-UP CHECKS Consult the system log to see if the following maintenance needs to be done: •...
Fill times are based on filling a single standard 80 cu ft aluminum cylinder from 500 psi to 3000 psi and are approximately as follows: YP25DF - 28 minutes per tank and YP35DF - 22 minutes per tank. Cylinder volume, starting tank pressure, and tank pressure ratings will vary the fill times.
Explanation: The YP25DF and the YP35DF compress air in three stages. Air leaving the outlet (discharge) of each stage is at an elevated temperature. The air passes through cooling tubes and the temperature is reduced prior to entering the inlet of the next stage.
Recommended Maintenance WARNING: We recommend that any maintenance other than preventative be performed by an authorized service center or technician. Contact Brownie’s for service center information. MAINTENANCE TYPE OF MAINTENANCE DATE SERVICE INTERVAL CENTER After 25 hrs initially, and Oil Change (every 50 hours when using regular oil, every 50 - 100 hours and every 100 hours if using synthetics) or thereafter...
VALVES Valve Functioning The valve heads of the individual stages form the top part of the cylinders. The intake and pressure valves are fitted inside the valve heads. Note that the valves are operated by the flow of the gas. On the suction stroke, the intake valves open and the gas flows into the cylinders, and on the compression the intake valve closes, and gas flows out the pressure valve.

CHANGING THE 2ND STAGE VALVES Both the pressure and intake valves can be serviced from the outside. • Remove two captive nuts (1) and springwashers (2). • Remove plate (3). • Remove valves (4) and (7) using two screwdrivers as shown in the diagram below.
CHECKING THE DRIVE BELT The best tension for belt drive is the lowest possible, while not slipping when under full load. This is best quantified by belt depression with thumb pressure between the two pulleys, with the belt deflecting ¼ “ (10mm) . •...
OIL LEVEL CHECK Check oil level daily prior to operating compressor. Use the dipstick and a lint free cloth to check the oil, by wiping off oil several times. Note that the oil level must be between the minimum and maximum dipstick notches. Add oil if necessary and recheck level.
