Frequently Asked Questions
Q: How do I adjust the pressure switch setting on a Truma/Flo-Jet pump?
First remove the cover cap from the end of the pump to reveal the pressure adjusting screw. A maximum of 1/4 turn clockwise or anti-clockwise from the factory setting is advised. Turning clockwise increases the cut-out pressure, anti-clockwise reduces it. Note that a second screw mounted below the cover cap is set with threadlock and should not be disturbed. The pump may need to be removed (drain the water system first, pull blue taps at right angles to pipe work and lift out) to gain access.
Q: How do I change a gas cylinder?
Turn off gas appliances, close the empty gas cylinder's valve, remove the high pressure hose from the gas cylinder, attach the high pressure hose to the full gas cylinder, and open the full cylinder's valve. Check the hose connection to the cylinder valve for leaks.
Q: How do I set the correct battery type on the PX310 battery charger?
After switching on charger press OK button for 3 seconds to enter Setup Mode, the battery type should then start to flash. Press the right arrow button to change battery type, then press OK to confirm.
Q: How do I activate or deactivate the Silent Mode on the PX310 battery charger?
During charging press the button for 3 secs to enter Silent Mode. Press the button again to exit Silent Mode. The charger will also exit Silent Mode when the charger is turned off then on again, or after 12 hours have passed.
Q: What is the Ford vehicle paintwork colour code for touch-ups or resprays?
Grey Matter PN4EG (note that colours can fade over time, so a colour match should be obtained if the vehicle is more than a few years old).
