The Truma Ultrastore has been used in most caravans from 2000 onwards.
240v Operation
The operation of the 240v system is quite straight forward, insure the heater is full of water and then turn on the 240v switch. This is normally situated at a low level under the front offside seat. It can however be anywhere in the caravan and there are a number of different types!
Once the heater is switched on the water will get to full temperature in 30 minutes, the water heater can be left of or the duration of your stay, however some people will turn it off a night to save energy.
If the heater fails to heat the water the thermal trip could have blown. This normally happens if 240v is supplied to the heater without the unit having waster in it This needs to be reset. To do this the 240v supply has to be disconnected from the unit. There is normally a white plug and socket close to the water heater. Take this apart, leave for a few minutes, then reconnect. The water should now heat.
Gas Operation
To light the gas water heater to flue cowl has to be removed, the heater will not light with it in position.
Turn the gray switch to the flame position, a green light will come on and the heater will attempt to light. It fails a red light will come on. Wait for a few seconds and try again. When the heater has lit the green light will stay on. There is a thermostat in the center of the gas control knob, set this to the required setting. The gas system needs to be used from time to time to ensure all the working parts stay in good condition.
Truma Ultraheat Units
Your Truma Ultra heat unit is responsible for the heating of your caravan. It is a duel fuel unit, this means that it runs on 240v mains electric and gas. The Ultra Heat is equipped with a fan that allows the warm air from the heater to be passed around the caravan via a system of pipes. This allows the whole caravan to be kept at a specific temperature.
240 Volt Operation
The heater has a mains switch, which has to be operated before the power can get to the temperature selector switch. The location of this switch varies depending on the make and model of caravan.
The heater has 3 settings on the 240v option, 500w. 1000w and 2000w. This is the maximum amount of power that will be used to heat the caravan at each setting. A green light will indicate that the power is on, the dial indicates which power output has been selected.
On the 2000w setting care has to be taken with other 240v appliances as the trip switch in the caravan can get over loaded.
The switch also has a thermostat setting dial which sets the temperature at which the thermostat operates. It is the dial with 1 through to 9 on it in the centre of the power selection switch.
The 240v heater can be used as a convector heater or the fan can be used to blow the warm air around the caravan.
Fan Operation: The fan is operated from the switch, which is located on the space heater. There are two settings - manual and auto.
The fan switch is located below the control dial numbered 1 through to 5. The centre position is off, to the left is manual and to the right is auto.
The manual fan is controlled by the numbered dial, 1, slow running fan through to 5 high speed fan.
The auto fan is controlled by a thermostat. The numbers on the dial correspond to a temperature at which the fan speed reduces. This will only work when the 2KW power output has been selected.
Gas operation
To operate the gas burner turn the gas control knob to 10 and depress fully. Hold in this position.
If you have an automatic ignighter you will hear a small “tick tick” noise. Keep the control knob depressed until the burner lights and the “tick” stops. Keep the control knob depressed for a further 10 seconds then release. The main burner will light; this can be seen through the viewing port in the cover.
If you have a manual ignighter depress the control knob for 5 seconds then press the manual spark knob repeatedly until the pilot light can be seen through viewing port.Keep the control knob depressed for 10 seconds then release, The main burner will light.
Most modern caravans will come with an oven and a microwave fitted as standard.
There are several different types of oven but they all work in the same principle. They run primarily on gas but some also have a 240v hob plate fitted. The hob has 3 gas rings (with one 240v hob plate if fitted). There is a separate grill with an oven below. All are fitted with a safety feature called a thermocouple which will shut the gas off if the flame has gone out, some are fitted with an extra safety feature that requires the hob lid to be in the fully raised position before the oven will work.
As with the ovens, most caravans are now fitted with a microwave that operates in the same way as the one at home, they run on 240v so will only work when plugged into the mains.
The caravan is equipped with a Thetford Cassette toilet that has a fresh water holding tank for the flush water and a waste holding tank for, well you know what.
Above is the water fill up point through which the fresh water flush tank can be filled. We don't recommend traveling with too much water in the tank as it will slosh about and adds weight to the caravan normally at the rear of the van, which isn't ideal.
A Flush additive can be used in the fresh tank, this helps lubricate the pump and keeps the tank free from mould build up.
Press the blue button that is situated on top out the toilet and a pump.
This will flush water around the bowl. A handle at the front of the unit just below the bowl can then be slid across to allow the contents of the bowl to pass into the cassette.
The blue chemical must be put in the cassette each time it gets emptied, to do this follow the instruction on the bottle and pour the required amount into the cassette through the bowl, and add some flush water.
When full, the Cassette can then transported to the waste deposal point, normally situated near the toilet block.
Fitted to all our caravans is a compact absorption refrigerator with a freezer. The fridge can run on 240v, gas and on 12v when the tow vehicle is running.
There are several different models of fridge but they all work on the same principle. Select the desired heat input, either 240v if you are plugged in, gas if wild camping and 12v if you are traveling. Then select the temperature control. We recommend this is set to three quarters as it gives the fridge a chance to get to temperature and rest. If it is set to high, it will never achieve it and will be running all the time.
In most cases the fridge will be running on the 240v. We recommend that the gas is used at regular intervals for a short period of time to keep it all working, normally once every three months for a few hours. If the gas has not been used for a year then the likely hood of it working when needed is slim.
