NAUTIC WATER HEATER
Our long experience in the nautical sector has enabled us to develop a series of water heaters with innovative
features compared to the market standard. The advantages that Quick®nautic water heaters offer are:
• High-quality materials ensuring durability and resistance over time.
• Heat exchanger with a large exchanging surface.
• Possibility of producing hot water even with the electric element, complete with adjustable and safety thermostat.
• Relief/non-return valve that allows the water heater to drain the water when not in use.
• Easy installation on a at area.

INSTALLATION AND USE MANUAL - QUICK B3 SERIES WATER Heater - REV001A
4 - Installation / Use
4.0 - Installation requirements
The water heater must be installed in a dry and well-ventilated place. This precaution is necessary, even if the
water heater is made of materials resistant to the marine environment, due to the presence of electrical devices
(in models equipped with them). In addition, installation in an unventilated place may cause condensation;
condensation may be mistaken for a false leak.
WARNING: do not install the water heater in environments with the presence of gas or potentially
ammable materials.
WARNING: the weight of the water heater indicated in the technical specications refers to empty
equipment. For the weight when fully loaded, add the weight of the mass of water lled in the
equipment to the weight when empty (1 litre of water corresponds to approximately 1 kg. / 2.2 lb).
4.1 - Installation procedure
A - Apply the brackets to the tank.
B - Fix the water heater to a at surface as shown in gure 1 (page 9) using supports suitable for the weight of the
water heater and the type of surface available for installation.
C - Make the hydraulic connections for the tap hot water input and output and the engine cooling circuit to the heat
exchanger (in models featuring it) as shown in gure 2 (page 9). The connection between the engine cooling circuit
and the water heater exchanger should be as short as possible.
WARNING: follow the engine manufacturer’s instructions to withdraw the coolant to be sent to the
water heater exchanger.
WARNING: the overpressure release pipe must be positioned on a continuous downward slope and
in a place protected from ice formation.
WARNING: water may drip from the overpressure stub pipe; leave this pipe open so that it can drain
the water in the atmosphere.
WARNING: use Loctite 243, 577 or Teon when installing the ttings.
Check that there are no water leaks.
4.2 - Use
WARNING: follow the engine manufacturer’s instructions to withdraw the coolant to be sent to the
water heater exchanger.
• Position the stub pipe (2) of the valve (1) securing it with the clamp (3).
Position it in such a way that any spillage of water will not damage other objects.
• Open the hot water taps of the washbasins and start the water pump. This allows
the air in the water heater and in the pipes to ow out. Close the taps as soon as
only water starts to ow out.
• Check that there is no leakage from the ttings.

INSTALLATION AND USE MANUAL - QUICK B3 SERIES WATER Heater - REV001A
4.2.0 - Cautions for use
Before connecting the equipment, make sure that cables are not live.
Never switch on the electric element if the water heater is NOT lled with water, otherwise the
heating element could be irreversibly damaged and the protection devices will not work properly.
WARNING: if the power cable is damaged, have it replaced at a Quick® service centre. To avoid
accidents, the equipment must only be opened by authorised personnel. The warranty will be void if
the equipment is opened by unauthorised personnel.
4.2.1 - DC power supply of the equipment
The equipment is provided with a box for DC network connections.
For connections to the DC network, see g. 3. Before supplying power to the water heater, make sure that its
operating voltage corresponds to that supplied by the DC network.
An equipment ON/OFF switch and a 30A fuse must be installed in the electrical system. The insulation material
between the contacts of the connections to the DC network must be at least 3 mm.
Connections to the DC network must be made in accordance with the national standards on electrical systems.
4.2.2 - AC power supply of the equipment
The equipment is already provided with a power cable for the AC network. For connections to the AC network,
see gure 3. Before supplying power to the water heater, make sure that its operating voltage corresponds to that
supplied by the AC network.
A double pole switch must be installed in the electrical system to turn the equipment on and off and a fuse suitable
for its absorption. The insulation material between the contacts of the connections to the AC network must be at
least 3 mm. Connections to the AC network must be made in accordance with the national standards on electrical
systems.
4.2.3 - AC thermostat setting
The thermostat factory-set temperature value is 60°C.
If you wish to change this value, follow the procedure below:
• interrupt the power supply.
• Remove the protection cover to reach the thermostat.
• Use a screwdriver to turn the thermostat knob and set the desired temperature value.
• Ret the protection cover.
• Restore the power supply.
The thermostat regulates the water temperature
only when operating with electric element.

6 - Maintenance
6.0 - B3Series maintenance
WARNING: if the overtemperature safety device is triggered repeatedly during the use of the water
heater, contact a Quick®service centre.
WARNING: if the power cable is damaged, have it replaced at a Quick®service centre. To avoid
accidents, the equipment must only be opened by authorised personnel. The warranty will be void if
the equipment is opened by unauthorised personnel.
• During the cold season, if the water heater is not in use, it is advisable to empty it using the valve lever (g. 1 page 7).
This is to avoid damage caused by frost.
• Periodically check the hydraulic system ttings for leaks; check the tightness of the fastening screws and replace
them if they are worn out or corroded.
• Periodically check the efciency of the electrical system.
6.1 - B3Series AC maintenance
WARNING: Quick®water heaters (only AC model) are equipped with a double thermostat with manual
reset that cuts off the power supply in the event of too high water temperature.
If this condition occurs, proceed as follows:
It is advisable to check the magnesium anode every 12 months.
Replace it if deteriorated.
This simple preventive maintenance guarantees a long
equipment life over time.
PROCEDURE for SINGLE-PHASE manual reset (only for AC model):
• Interrupt the power supply
• Remove the protection cover (B) to reach the thermostat (C).
• Use a screwdriver to turn the thermostat knob (g. 4 page 10) and
set the maximum temperature value.
• Press the reset button on the double thermostat (g. 4 page 10).
• Use a screwdriver to turn the thermostat (C) knob and set the
desired temperature value.
• Ret the protection cover (B).
• Restore the power supply.
