WARNING
Due to the presence of glycol, corrosion of the system is
possible. Uninhibited glycol will turn acidic under the
influence of oxygen. This process is accelerated by the
presence of copper and high temperatures. The acidic
uninhibited glycol attacks metal surfaces and forms
galvanic corrosion cells that cause severe damage to the
system. Therefore it is important that:
▪ the water treatment is correctly executed by a qualified
water specialist,
▪ a glycol with corrosion inhibitors is selected to
counteract acids formed by the oxidation of glycols,
▪ no automotive glycol is used because their corrosion
inhibitors have a limited lifetime and contain silicates
which can foul or plug the system,
▪ galvanized pipes are NOT used in glycol systems since
the presence may lead to the precipitation of certain
components in the glycol's corrosion inhibitor.
Electrical installation (see "6Electrical installation"[413])
DANGER: RISK OF ELECTROCUTION
WARNING
Electrical wiring connection method MUST be in
accordance with the instructions from this manual. See
"6Electrical installation"[413].
WARNING
▪ All wiring MUST be performed by an authorised
electrician and MUST comply with the applicable
legislation.
▪ Make electrical connections to the fixed wiring.
▪ All components procured on-site and all electrical
construction MUST comply with the applicable
legislation.
WARNING
ALWAYS use multicore cable for power supply cables.
CAUTION
Do NOT push or place redundant cable length in the unit.
WARNING
The backup heater MUST have a dedicated power supply
and MUST be protected by the safety devices required by
the applicable legislation.
CAUTION
To guarantee the unit is completely earthed, always
connect the backup heater power supply and the earth
cable.
WARNING
Stripped wire. Make sure that stripped wire cannot make
contact with possible water on the bottom plate.
Maintenance and service (see "10Maintenance and
service"[435])
WARNING
If the internal wiring is damaged, it has to be replaced by
the manufacturer, its service agent or similarly qualified
persons.
DANGER: RISK OF BURNING/SCALDING
The water in the tank can be very hot.
CAUTION
Water coming out of the valve may be very hot.
CAUTION
Although the water circuit is drained, some water may be
spilled when removing the magnetic filter/dirt separator
from the filter housing. ALWAYS clean up spilled water.
CAUTION
To protect the piping connected to the magnetic filter/dirt
separator from damage it is recommended to perform this
procedure with the magnetic filter/dirt separator removed
from the unit.
CAUTION
Opening the magnetic filter/dirt separator is ONLY required
in case of severe issues. Preferably this action is never to
be done during the complete lifetime of the magnetic filter/
dirt separator.
CAUTION
Check the condition of the O-rings and replace if needed.
Apply water to the O-rings before installation.
CAUTION
Make sure to open the valve (if equipped) towards the
expansion vessel, otherwise the overpressure will be
generated.
Commissioning (see "8Commissioning"[432])
WARNING
Commissioning method MUST be in accordance with the
instructions from this manual. See
"8Commissioning"[432].
