2. DESCRIPTION
The USW-1 is an upright free-standing water heater with a single heat exchanger (coil) and can be connec-
ted to an independent, central or district heating system or it can be used in forced-circulation solar heating
systems. The USW-2 is an upright free-standing water heater with a double heat exchanger (coil) that can
be connected to a thermal solar collector, which uses solar panels to generate domestic hot water, or used
when it is important to split up the heat exchanger surface due to considerable uctuation in demand.
In both models the surface of the heating element is large enough to produce large quantities of hot water.
The lower part of the exchanger is angled downwards to allow the entire volume of water in the storage tank
to be heated. LAS-E electric heating elements . It is necessary to be especially careful when electric power
is switched on by a qualied engineer according to the separate manual. Water must be lled up in the sto-
rage tank at anytime! Perfect insulation is provided by extra-thick high-density eece-or soft foam.
3. OPERATION
This water heaters are designed for domestic hot water supply in residential or industrial applications hea-
ted by hot water, electricity, or indirect heated by separate heat exchangers.
It can be installed in any heat pump or solar panel heating system.
The water heater must be connected to the water supply via the cold water coupling and to the hot water
utilities via the hot water coupling. When hot water is required, cold water enters the tank where it is heated
to the temperature set on the thermostat, if there is one.
The ideal setting is 60-65 °C because this temperature guarantees the best performance of the water heater
as well as:
• maximum hygiene
•cost effectiveness
•reduced scaling
4. INSTALLATION
This appliance is designed to heat domestic hot water to a temperature below
boiling point at atmospheric pressure. It must be connected to a heating system
and a domestic hot water distribution network that are compatible with its perfor-
mance and power specications.
The following operations must only be carried out by professional qualied per-
sonnel. Failure to follow this rule will invalidate the warranty.
4.1 Choosing a location
The place of installation must be protected from frost.
The product must be as close as possible to the heat generator. This is to avoid heat loss. If this is not pos-
sible, it is important to insulate the connection pipes.
It must be positioned so as to allow laying all pipes works.

4.2 Plumbing connections and preliminary operations
The position and function of the couplings are shown in the label attached.
It is advisable to install the appliance as close as possible to the point where most water is used, in order to
avoid heat loss along the pipes. It should also be close to a drain for convenience when emptying it.
A safety valve must be installed in the cold water pipe upstream of the heat exchanger.
It must not be possible to shut off the pipe connecting the heat exchanger and the safety valve as this would
damage the heat exchanger due to overpressure.
Take care when installing the safety valve. Do not force or tamper with it. The safety valve a rated setting
of 6 bar. Slight dripping from the safety valve is normal during heating, so it is advisable to connect it to a
trapped drain. If the mains pressure is close to the valve setting, install a suitable pressure reducer as far
away from the water heater as possible.
If the system has a pressure reducer and/or a non-return valve, it is mandatory to
install an expansion vessel the capacity of which is not less than 5% of the rated
capacity of each heating element.
Non-return valves must not be installed between the safety valve and the expansion vessel.
In general, in order to protect the appliance and the system, it is always advisable to install an expansion
vessel as specied above.
Inate the diaphragm chamber of the expansion vessel as instructed by manufacturer.
Before connecting the appliance to the mains, ll it with water as follows:
•turn on the cold water tap:
• turn on a hot water tap (e.g. bath, sink, etc.), bleed air from the system and wait for a constant ow
of water from all the water
taps;
•check all the plumbing connections for leaks.
When the local water is hard, it is advisable to install specic devices to prevent excessive scale build-up.
Please note that some of them are similar to non-return valves, which means that a suitable expansion
vessel must be provided.
The appliance can have a recirculation pipe connected to it. If this is done, the pipe must be insulated.
For recirculation it is necessary to install a pump tted with a timer or a minimum contact thermostat to acti-
vate cooling of the recirculation water. If the coupling is not used, a seal cap must be provided.
The inlet and outlet pipes must be connected at the established points of the heat exchanger.
• Check that the thermal output of the heat generator is at least 15% higher than the thermal input of
the water heater.
• If there are any impurities in the mains water, provide a suitable lter and check that the circulation
pumps have a sufcient ow rate and pressure head and work efciently.
•Make sure the thermostat and thermometer probes are positioned correctly.
•Check that the thermostat controls operate correctly.
The plumbing system must be connected as shown in the label attached.

5. START-UP PROCEDURE
When the product has been installed, ll it with cold water for the domestic hot water system and turn on a
tap to bleed air from the system.
Then ll with water for the heating system and turn on a hot tap to bleed air out.
Regulate the hot water temperature in the system on the instrument as instructed. The recommended tem-
perature setting is 60-65 °C.
Check periodically that all the control and regulation devices are in proper working order.
The water heating system must be started up by a qualied service angineer.
5.1 Filling the heat exchanger
The heat exchanger element is connected to the heating circuit (s), so to ensure that water is circulating
inside merely check that the water pressure inside the boiler is high enough for it to operate correctly.
Refer to the primary head instructions for further details.
5.2 Filling the appliance
This requires a tap for lling the domestic hot water circuit. Turn on the heat exchanger tap and turn on any
tap to bleed the system.
5.3 Emptying the appliance
Turn off the mains lling tap, connect one end of a hosepipe to the drain outlet and place the other end in an
external drain.
Turn on a tap and leave it on; open the drain outlet and allow the system to empty completely in a slowly
way.
6. MAINTENANCE AND CLEANING
Always empty the appliance before carrying out any maintenance work.
6.1 General points to remember
The outside of the product can be cleaned with a soft cloth and a suitable cleaning product. Do not use
abrasive products, solvents, petrol, alcohol or the like.
Do not use water.
If the appliance is used in a room where the temperature may go below zero, it must be left running or emp-
tied completely.
6.2 Inspecting and cleaning the inside of the tank
To clean inside the tank, drain the appliance slowly, unscrewes in the plastic cap and remove the cover.
Remove the counter-ange or screwes from the inspection openings.
Take care during cleaning not to damage the tank and heat exchanger (heating element).
Clean with a jet of water. If necessary use a suitable tool made of wood or plastic to remove any build-up of
scale.
Lastly, remount the ange and gasket (replace the latter if damaged), ll the tank and check for leaks from
the ange and tap.
Fill the appliance, referring to the start-up instructions, and check for leaks.
If the local water is particularly hard, it is advisable to de-scale the water heater at least once a year.
