Specific installer safety
instructions

Always observe the following safety instructions and regulations.

Installation site (see 

"4.1 Preparing the installation site"

 [

4

 4])

WARNING

Follow  the  service  space  dimensions  in  this  manual  for
correct  installation  of  the  unit.  See 

"4.1.1  Installation  site

requirements of the indoor unit"

 [

4

 4].

Opening and closing the unit (see 

"4.2 Opening and closing the

unit"

 [

 5])

DANGER: RISK OF ELECTROCUTION

DANGER: RISK OF BURNING/SCALDING

Mounting the indoor unit (see 

"4.3 Mounting the indoor

unit"

 [

4

 6])

WARNING

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

"4.3  Mounting

the indoor unit"

 [

4

 6].

Piping installation (see 

"5 Piping installation"

 [

 7])

WARNING

The  field  piping  method  MUST  be  in  accordance  with  the
instructions 

from 

this 

manual. 

See 

"5 

Piping

installation"

 [

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.

Electrical installation (see 

"6 Electrical installation"

 [

4

 10])

DANGER: RISK OF ELECTROCUTION

WARNING

Electrical  wiring  connection  method  MUST  be  in
accordance with the instructions from:

▪ This manual. See 

"6 Electrical installation"

 [

4

 10].

▪ The  wiring  diagram,  which  is  delivered  with  the  unit,

located  on  the  inside  of  the  indoor  unit  switch  box
cover.  For  a  translation  of  its  legend,  see 

"10.2  Wiring

diagram: Indoor unit"

 [

4

 33].

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.

WARNING

If the supply cord is damaged, it MUST be replaced by the
manufacturer,  its  service  agent  or  similarly  qualified
persons in order to avoid a hazard.

CAUTION

Do NOT push or place redundant cable length into the unit.
