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 fluctuation 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 qualified engineer according to the separate manual. Water must be filled up in the sto
-
rage tank at anytime! Perfect insulation is provided by extra-thick high-density fleece-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 specifications.
The following operations must only be carried out by professional qualified 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.
