When unused for short periods of time
In the event of the integrated solar collector with accumu-
lation tank not being used for a period of up to 30 days it
is possible to leave the plant filled with water and the solar
collector uncovered.
Nevertheless, before reusing the hot water it is a good idea
to completely empty the tank and then refill it again.
In case of not using the collector for longer periods (e.g.
when putting out of service in winter), completely empty
the accumulation tank (see below) and cover with the sheet
supplied.
Emptying
Whenever it is necessary to empty the EGO or EGO
PRIME system, for example in case of maintenance or
protection against low temperatures, carry out the following
steps:
Before the emptying operation, the solar collector
must be covered with the sheet supplied or with
an appropriate blacking-out system, in order to
avoid causing damage to the system by any heat
that could form inside due to the absence of water.
a) Turn on a tap of one of the users and allow a sufficient
amount of water to flow in for lowering the temperature
and rinsing out the system.
b) Close the shut-off valve at the inlet.
c) Disconnect the return line from the by-pass valve.
d) Open the drainage tap and convey the outlet water down
the drain.
If any antifreeze or integration resistors have been
installed, these must be deactivated.

Types of elecric resistor
Even though the system was designed to operate in
temperate zones with good radiation, it has a greater range
of uses if combined with ELECTRIC RESISTORS, available as
optional accessories to be requested.

Installing the electric resistors
If electric resistors are to be installed after the collector
has been started, it must be covered previously with the
supplied cover sheet (or with a suitable darkening system)
and emptied completely.
•
The integration resistor
(1 and 2 kW) must be in-
I
stalled in the upper part of the solar collector, opposite
the side where the outflow connection is positioned
•
The antifreeze resistor
(0,3 kW) must be installed in
L
the lower part of the solar collector, opposite the side
where the inflow connection is positioned
.
G

Using a plastic spanner of 1"1/4, unscrew the
plastic cap, being careful not to damage it and
making sure that the O-ring remains in its seat.
Insert the resistor into the hole and tighten
it by hand, without using tools; the structure
of the resistor and its connection to the solar
collector collector were designed to avoid their
use. Tightening by hand is enough to guarantee
system sealing.
50
Do not use any type of tool to tighten the electric
resistor; using tools can damage the sealing
thread, resulting in the appearance of leaks. In
this case, the manufacturer will not recognise any
guarantee rights.
Connect the power cable to an electric socket and check the
earthing connection.
These accessories can only be connected
to the electric power supply by a qualified
installer who is authorised to operate in the
installation area. The installer must apply all
precautions to respect standards, above all
those regarding safety, and to eliminate any
risk situation.
RISK OF ELECTRIC SHOCK
Do not connect the electric resistors at current values that are
different from those given on the plate.
Indications on using electric resistors
Should the risk of the temperature falling below 0°C be
present, the "EGO or EGO PRIME" solar collector with
integrated storage must be emptied and covered with the
PVC cover sheet. Alternatively, and always with outdoor
temperatures of not below -5°C, the antifreeze electric
resistor can be installed.To prevent the formation of ice
inside the piping, in addition to the antifreeze electric
resistor, we recommend insulating the water supply lines,
.
M
especially the outdoor sections.The 1 and 2 kW electric
resistors should be used if the "EGO or EGO PRIME"
solar collector with integrated storage is connected directly
to the user, without the addition of a boiler downstream.
In periods when there is less solar radiation, and in the
colder months, the 1 and 2 kW resistors integrate the solar
M
collector in order to take the water temperature in the
accumulation tank to values that are near those used. It is
recommended to schedule the electrical heater operation
I
just 2 hours before the programmed use of hot water.
The electric resistor settings were selected to optimise system
L
duration and operation, and were set in the factory.
Altering these values is considered as tampering with the
product, which can cause possible faults and damage; in this
case the manufacturer will not recognise any guarantee rights.
To guarantee correct resistor operation and prevent
damaging the solar collector with integrated storage, only
the types of electric resistor proposed by the manufacturer
can be used. No guarantee rights will be recognised if other
types of seals or additions are used.
If any antifreeze or integration resistors have been
installed, in the event of emptying the collector these must
be deactivated.
