N/A | Reverse Polarity light is illuminated on PSU - Mains Supply reversed Possible Cause: The reverse polarity light is designed to illuminate when the Live and Neutral supply has been reversed / crossed over. | The reverse polarity light is designed to illuminate when the Live and Neutral supply has been reversed / crossed over. If the light illuminates there is a problem with the site supply or the cable connecting the supply to your vehicle. The light is designed to work on UK electrical supplies (where the neutral conductor is connected to earth at the sub station). If you are using your vehicle outside the UK this light may illuminate when no fault exists. In these cases, consult the site warden for advice. | Professional Intervention Required |
N/A | Reverse Polarity light is illuminated on PSU - Generator being used Possible Cause: Instead of connecting the neutral conductor to earth, some generators centre-tap the earth connection making both neutral and live conductors 110V above earth, causing the neon polarity indicator to illuminate. | This is a normal side effect when using some types of generator. Instead of connecting the neutral conductor to earth, some generators centre-tap the earth connection making both neutral and live conductors 110V above earth. This 110V difference causes the neon polarity indicator to illuminate. In most cases it is still safe to use the generator, but please consult the generator handbook for further information. | DIY Safe |

Frequently Asked Questions
Q: How do I choose and fit a child seat in my Swift motorhome?
Go to a reputable retailer like Halfords, Smyths, or John Lewis that has trained advisers and offers a fitting service. Ask the adviser to fit various seats to the motorhome to verify suitability before buying. For height-based 'i-Size' seats or weight-based seats, ensure they are EU-approved (showing a capital 'E' in a circle with 'R129' or 'ECE R44'). Position them on the front passenger cab seat (ensuring airbag advice is followed) or the forward-facing rear seat. For ISOfix seats, use the aisle seat with ISOfix brackets and attach the top tether located under the headrest. For non-ISOfix seats, the window seat is recommended and the aisle seat is not recommended. Always push your weight into the child seat as you tighten the adult inertia reel belt so it is tight, and follow the child seat manufacturer's fitting instructions.
Q: How do I prime the water system in my motorhome?
1. Close the water tank drain valve. 2. Fill the water tank with water. 3. Close the water heater drain valve (see boiler instructions in the fitted equipment section). 4. Open all taps except the shower tap; mixer taps should be in the central position so both hot and cold pipes are purged, with spouts over the sinks. 5. Turn on the pump using the button on the control panel. 6. Turn each tap off in turn once air is expelled and water runs smoothly, moving mixer taps to hot and cold to check both pipes. 7. Hold the shower head down towards the shower drain, open the shower tap and shower head tap until air is expelled and water runs smoothly, then turn the shower taps off. 8. Top up the fresh tank with water.
Q: How should I clean and sterilise the motorhome water system?
Clean the water system at the start and end of the season using a suitable sterilising fluid available from your motorhome dealer that is suitable for stainless steel components. Do not use products containing aggressive agents, bleach, or sodium metabisulphite. Always flush the system thoroughly to remove any traces of cleaning fluids. For separate water containers: empty remaining water, clean and wash down the outside with hot water and detergent, rinse, fill completely with sterilising fluid mixed to the manufacturer's recommended strength and allow to stand for the recommended contact time, empty the solution, clean the container opening with an appropriate sterilising wipe, and store the container inverted overnight if possible.
Q: How do I adjust the pressure switch on the Truma/Flo-Jet pump?
First remove a 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 the screw clockwise 1/4 turn increases the pressure switch cut-out pressure, and turning it anti-clockwise reduces the pressure setting. Do not disturb the second screw mounted below the cover cap which is set in position with threadlock.
Q: How do I remove the leisure battery for inspection or replacement?
Step one: remove the lower front seat fascia by pulling on the clip feature located centrally on the upper edge using an upwards direction. Step two: release the battery harness by cutting zip ties securing it to the lower seat frame, then disconnect the battery harness connector by pulling firmly on each large black connector plug. Step three: remove two fabric straps by loosening them through the buckles. Step four: pull the battery forward out from under the seat frame. Step five: cut zip ties securing battery terminal covers, remove covers, and demount battery terminals using a 10mm spanner taking care not to short the terminals.
Q: How do I care for the laminate surfaces, worktops, tables, and furniture doors?
Clean worktop surfaces, furniture, and door fascias with a soft, slightly damp cloth, and dry off with a soft cloth. Do not use abrasives, chemically treated cloths, or aggressive detergents. Do not place hot objects of 70°C and over on laminated surfaces.
