General Information
This water boiler is designed for motor yachts, campers, caravans and trailers.
1. Please keep this manual for future reference & read it thoroughly.
2. Only a qualied electrician should install the unit to ensure it is properly installed.
3. This water boiler creates extremely hot water temperatures that may cause scalding. Be sure
to mix cold water and hot water before bathing/washing. When using this appliance, close
supervision of children is necessary.
4. The pressure relief valve (safety valve) shall be installed in the specied location (**see
diagram). No modication is acceptable. When water pressure is high enough, it is normal that
some water drops will escape from the pressure relief valve. Do not block the pressure relief
valve. Connect a drain hose to the pressure relief valve and lead it to drain for the exterior of
the camper. The pressure relief valve may be hot, please be careful not to burn yourself.
5. Make sure to unplug the water heater before you perform any maintenance, or wish to
examine, repair or adjust it. A qualied electrician should do all maintenance.
6. Water heater should be installed near the water drain pipe. Keep the drainpipe owing.
Expedition Uptter is not responsible for any loss of use or damage due to water leaks or spills.
7. If the power cord is damaged, be sure to have it replaced by an after-sales service technician
with a special cord, oered by the manufacturer. Contact Expedition Uptter to order. Many
of the components are insulated and protected with an insulation layer. Please consult with
Expedition Uptter before making any alterations.
8. It is strictly prohibited to use this water heater during a thunderstorm. This is to ensure your
personal safety.
9. Please cut o power to the plug and turn o the inlet valve when the water heater is not in
use for a long period of time.
10. The inlet and outlet lines are 1/2” BSP ttings we now provide you with two 1/2”BSP to NPT
ttings these should be connected rst with Teon tape.

Safety Valve
There is a safety valve (pressure relief valve)
supplied with the water heater. While the device
is heating, expect a few water drops to fall. This is
normal as it helps to decrease the pressure in the
tank. The back pressure valve ensures that hot
water does not ow back into the cold water
supply. The safety valve has been preset rated to
7Bar in factory. Do not adjust.
Installation
Choose a place that is as close as possible to the hot water tap in order to avoid unnecessary
loss of heat caused by a long water supply line. Install the boiler in a horizontal position (not in
a vertical position). The water boiler should be in a convenient location so that regular
maintenance and repairs can be made. It’s ideal if you can isolate the boiler so if there are any
water leaking issues the damage to your camper will be minimized.
Pressurized hot water boilers have to be equipped with the safety valve provided to protect
the unit from excess pressure. Excess pressure may build up and must be allowed to escape via
a safety valve drain hose. Install the safety valve and the drain valve at the drain outlet of the
boiler. Connect an additional hose to the safety valve leading to the outside or to a tank to
make sure that the excess pressure water can run out.
The correct water connection is very important for the proper functioning of this boiler. Use
pressure-resistant and non-toxic water hoses and attach them with stainless steel clamps.
*Attention*
The safety valve must not be blocked at the drain outlet.
Attach water lines with stainless ttings, use high quality braided tubing and Teon tape for all
threaded connections.

Drain Hose
After having installed
all water connections,
open your water
supply and your hot
water tap to ll the
boiler with water. Once
the boiler is completely
full, water will run out
of the hot water tap.
Thanks to its Safety
design, the boiler cannot inadvertently drain itself. You can only empty the boiler completely via a
drain valve.
First ll the boiler with water before connecting to the power. Check for water leaks before
**

connecting. Use a minimum 1.5mm or 16 gauge wire. Hook up to a 20amp fuse before
you hook up to your 20amp circuit breaker (red/brown is positive). Use the thermostat to
set the temperature. The set temperature is controlled automatically, the signal lamp
indicates the heating up of the boiler. The temperature is continuously adjustable.
*Caution! Do not operate the boiler without water*
If the boiler is operated electrically without water, the temperature safety device installed
in the heating element will come into action as soon as the excess heating temperature of
110° is reached and will switch the boiler o electrically. The temperature safety device is
located in the probe tube of the heating element.
You have two possibilities to protect your boiler from frost:
1. Keep the boiler connected to the battery and set the thermostat to the lowest setting.
Thus, the water temperature is kept above the freezing point. The electricity consumption
for this method is very low.
2. Empty the boiler via the drain valve. If the water does not run out, open the water taps
to allow air to enter the supply lines. You may need to blow out your lines to completely
remove the water.
Warranty
All devices are carefully checked before leaving our plant. We grant 1 year of warranty on
all parts. The Warranty starts to run on the day of manufacture. Warranty is not granted in
case of damage caused by frost or calcication, by meddling or by improper use. Warranty
is granted if the manufacturer has been informed about the damage right after it occurred
and if the return of the boiler to the manufacturer has been agreed upon with Expedition
Uptter beforehand.
All other claims are excluded.
In case of malfunctioning please try to get information by phone rst. It might be possible
to repair the boiler at your place without having to send it to the manufacturer.
Maintenance
If you notice that the water has white scales in it that means its time to replace the
magnesium rod (Typically after 1.5 - 2 years of continuous use). This is a simple x that
takes about 20 mins or so. You can order your replacment parts at expeditionuptter.com.
We can supply you with an instructional video for the replacement. We also carry spare
heating elements and other parts if needed.
