1. Fitting the Water Heater
Mounting templates can be downloaded from the Transvend website: www.transvend.com.
Ensure that all water heaters are tted level and mounted in accordance with the instructions so that
the tap cannot be accidentally operated or knocked.
Mount the heater unit in such a way to :
• Prevent splashing onto the vehicles occupants.
• Prevent any interference with the driver.
• Prevent exposure to hosed water/jet wash devices.
• Eliminate any possibility of accidental operation/opening of any emergency door
• Allow easy access to any grab/safety handles.
• Protect it against airborne contaminants and accidental damage, a tap cover may need to be
tted depending on tting location.
Water Heater Mounting
Mount the heater to a secure vertical surface. Only use the bolts provided to screw into the heater, if
longer bolts are used they may damage electrical components within the heater.

2. Connecting to Power
• IMPORTANT! Check your +ve and -ve negative supply cables are correctly labelled.
DO NOT REVERSE THE POLARITY.
• Check the serial label underneath the water heater for the current and wattage rating.
• Cable thickness – The supply cable should be a minimum 10mm2.
• The water heater is supplied with a heavy duty socket to enable quick connection of the heater
(12vdc & 24vdc only).
• Contact pins to t to the supply cable are included, these should be terminated either by crimping,
with a heavy duty crimper, or soldering.
• Position the front of the contact pin so that it slips under the barrier and snaps over the end of the
retaining spring, listen for the ‘SNAP’.
• The supply cable should be fused with a 50A fuse for a 30A heater.
• The supply cable should be fused with a 80A fuse for a 60A heater.
• We recommend the use of screw type connections that cannot work loose.
• The cables should be tted to a suitable fuse block.
• Check the vehicle manual or refer to the dealer before tting to ensure that the heater will not
overload the electrical system.
• If the incorrect size of supply cable is used, loss of performance may result and the supply cables
may become hot and may become hazardous.
• If in doubt seek professional advice.
• Earth connection cable should be a minimum of 10mm2.
• Use a nut and bolt with large at washers to make the connections to the earth point. The earthing
point should be free from corrosion and paint to ensure a metal to metal
connection. Suitable battery termination grease can be applied to the earthing point after
connection.

Fuse Information
When installing Transvend equipment it is important to fuse the water heater correctly. Transvend rec-
ommend the use of either a MIDI / MEGA bolt-down fuse and the associated housing or an automotive
MAXI fuse. Make sure that the fuse is rated in accordance with the water heater specication.

• Turn the machine on using the On/O Button on the front of the heater.
• The Power On LED and the Low Water LED will illuminate.
• Fill the heater with fresh clean drinking water to the MAX mark DO NOT OVER FILL.
• The Low Water LED will go out and the Heating LED will illuminate.
• Check to ensure water ows from the tap.
• The temperature has been factory set to 920C, when this temperature is reached the Heating LED
will go out and the Ready LED will illuminate.
• When the Ready LED is illuminated the water has reached the correct temperature.
Features only available on 12vdc and 24vdc water heaters.
If ‘Frost Protection’ is activated:
• If the water heater has‘Frost Protection’ activated then the water heater will keep the temperature
of the water above 30C. This stops any risk of damage from expanding freezing water.
If ‘Voltage Sensing’ is activated:
• If the water heater has‘Voltage Sensing’activated then it has a factory dened or user dened
voltage threshold set. This feature is recommended if you’re wiring the water heater to any
supplementary or leisure batteries in the vehicle and don’t already have some form of battery
protection in use. It will stop your supplementary or leisure batteries from going at if the water
heater is in operation.
If Alternator Sensing’ is activated:
• If the water heater has‘Alternator Sensing’activated then it will sense when your engine is running.
This feature is recommended if you’re wiring the water heater to the vehicles main battery. It will
stop your main crank battery from going at if your water heater is in operation.
If ‘Press To Heat’ function is activated:
• If the water heater has‘Press to Heat’ activated then it will be set to ’once only’ heating cycles. The
water temperature will reach 920C, when it cools and reaches 870C the water heater will turn itself
o. The user will have to press the On/O Button to start another heating cycle.

• Transvend recommends the use of ‘Milton Sterilising Fluid’ which is a chlorine based agent for the
inside of the water container. Always follow the manufactures instructions carefully.
Servicing & Maintenance
• See website for error codes.
• The most likely problem to be encountered is the build-up of lime scale within the heater and tap.
This can be removed using a proprietary kettle descaler.
• Descale regularly, to keep your water heater in good working order.
• Follow the instructions on the descaler, rinse several times, then ll, heat until ready and discard the
water, to ensure no residues are left.
