Check/Replacement Of The Sacrificial Anode; Emptying The Tank; Replacement Of The Power Cord; Requirements For The Operation, Service And Installation - Ferroli EGEA TECH 200 HT Manual

If the operator is unable to elim­
inate the fault, switch off the
equipment and contact the Tech­
ATTENTION
nical Assistance Service, com­
municating the model of the
product purchased.
9.3 CHECK/REPLACEMENT OF THE SACRIFICIAL
ANODE
The integrity of the Mg anode must be checked at least eve­
ry two years (better once a year). The operation must be
performed by qualified personnel.
In fact, magnesium is a weakly charged metal compared to the
material of which the inside of the boiler is coated, therefore it
attracts first the negative charges that form with the heating of
water, consuming itself. The anode therefore "sacrifices" itself
by corroding itself instead of the tank. The boiler has an anode
mounted at the bottom of the tank.
Before doing the check:
• Close the cold water inlet.
• Proceed with emptying the boiler (see par. "9.4 EMPTYING
THE TANK").
• Unscrew the upper anode and check its corrosion; if the cor-
rosion affects more than 2/3 of the anode surface proceed
with replacement.

EMPTYING THE TANK

When not in use, especially in the presence of low temperatu-
res, it is advisable to drain the water present inside the tank.
For the appliance in question, just disconnect the water inlet
connection (see par. "8.7 Hydraulic connections" on page 173).
Alternatively, if you are setting up the system, it is recommended
that you install a drain cock.
NB!: empty the system in case of low tempe­
ratures in order to avoid freezing phenomena.

REPLACEMENT OF THE POWER CORD

DO NOT TAMPER WITH THE
POWER CORD.
If the power supply cable is dam­
ATTENTION
aged, it must be replaced by the
manufacturer or the technical as­
sistance service or in any case
by a person with similar qualifi­
cations, in order to prevent any
risk.
The cable must be replaced in compliance with the laws in force
in the country where the product is used.
Replace the damaged power cord with a new one with the same
or equivalent characteristics to the original cord.
