Step 1: Choose Your Power Source

Your hot water system runs on two power options:

• 240V mains power – when you’re plugged into a campsite outlet
• LPG gas – when you’re free camping without power

Choose the one that suits your setup, and follow the relevant instructions below.

Step 2: Running the System on 240V Power

• Plug your vehicle into a 15AMP campsite power source.
• Once connected, the water will heat automatically within 20–25 minutes.

Don’t forget: You still need to activate the correct switches inside (see Step 4).

Step 3: Running the System on LPG Gas

1. Go to the rear driver’s side of your motorhome to locate the gas bottles.
2. Ensure the top selector switch is pointing at the bottle you want to use.
3. Open the selected gas bottle fully—partial opening can cause failure.
4. Head inside and continue with the steps below.

Step 4: Switch on the Right Controls

There are two types of control panels. Identify which one you have:

• Black Panel: Turn on both the 12V and Tap buttons.
• White Panel: Turn on the Tap button only.

This step is required for both 240V and gas operation.

Step 5: Set the Thermostat

At the kitchen sink, locate the thermostat switch and:

• Push it up to 60°C to begin heating on gas.
• Heating should complete in around 30 minutes.

Step 6: Troubleshooting Errors

• If you see a red light stay lit, it means something went wrong.
• Check that:
  • The gas bottle is fully open.
  • The selector switch is pointing to the correct bottle.
  • The control panel switches are correctly activated.
  • The thermostat is set to 60°C.

Then retry the process.
