DANGER: RISK OF BURNING/SCALDING

Mounting the outdoor unit (see

"7.3 Mounting the outdoor unit"

WARNING

Fixing method of the outdoor unit MUST be in accordance with the instructions from
this manual. See

"7.3 Mounting the outdoor unit"

CAUTION

To avoid injury, do NOT touch the air inlet or aluminium fins of the unit.

WARNING

Rotating fan.

Before powering ON or servicing the outdoor unit, make sure that the

discharge grille covers the fan as protection against a rotating fan. See:

▪

"7.3.6 To install the discharge grille"

▪

"7.3.7 To remove the discharge grille, and put the grille in safety position"

Mounting the indoor unit (see

"7.4 Mounting the indoor unit"

WARNING

Fixing method of the indoor unit MUST be in accordance with the instructions from
this manual. See

"7.4 Mounting the indoor unit"

Piping installation (see

"8 Piping installation"

)

WARNING

Field piping method MUST be in accordance with the instructions from this manual.
See

"8 Piping installation"

In case of freeze protection by glycol:

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.

WARNING

Ethylene glycol is toxic.
