Specific installer safety
instructions
Always observe the following safety instructions and regulations.
Opening and closing the unit (see
DANGER: RISK OF ELECTROCUTION
DANGER: RISK OF BURNING/SCALDING
WARNING
Fixing method of the indoor unit MUST be in accordance
with the instructions from this manual. See
7].
WARNING
Field piping method MUST be in accordance with the
instructions
from
this
manual.
See
7].
WARNING
Install the tundish away from any electrical device.
Possible consequence:
Electrical shock or fire.
In case of freeze protection by glycol:
WARNING
Ethylene glycol is toxic.
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.
