2

Remove  the  burrs,  and  paint  the  edges  and  areas  around  the
edges using repair paint to prevent rusting.

4.2.4

To prevent the outdoor unit from falling
over

1

Prepare  2  cables  as  indicated  in  the  following  illustration  (field
supply).

2

Place the 2 cables over the outdoor unit.

3

Insert  a  rubber  sheet  between  the  cables  and  the  outdoor  unit
to prevent the cable from scratching the paint (field supply).

4

Attach the cable’s ends. Tighten those ends.

4.3

Connecting the water piping

4.3.1

To connect the water piping

NOTICE

Do  NOT  use  excessive  force  when  connecting  the  piping.
Deformation of the piping can cause malfunctioning of the
unit.  Make  sure  that  the  tightening  torque  does  NOT
exceed 30 N•m.

To facilitate service and maintenance, 2 shut-off valves are provided.
Mount  the  valves  on  the  water  inlet  and  on  the  water  outlet.  Mind
their  position:  the  integrated  drain  valves  will  only  drain  the  side  of
the  circuit  on  which  they  are  located.  To  be  able  to  only  drain  the
unit, make sure the drain valves are positioned between the shut‑off
valves and the unit.

1

Screw the outdoor unit nuts on the shut-off valves.

2

Connect the field piping on the shut-off valves.

NOTICE

Install a manometer in the system.

NOTICE

Install air purge valves at all local high points.

4.3.2

To protect the water circuit against
freezing

If  negative  outdoor  temperatures  are  expected,  add  glycol  to  the
water  circuit.  The  required  concentration  depends  on  the  lowest
expected  outdoor  temperature,  and  on  whether  you  want  to  protect
the  system  from  bursting  or  from  freezing.  To  prevent  the  system
from  freezing,  more  glycol  is  required.  Add  glycol  according  to  the
table below.

INFORMATION

▪ Protection  against  bursting:  the  glycol  will  prevent  the

piping  from  bursting,  but  NOT  the  liquid  inside  the
piping from freezing.

▪ Protection  against  freezing:  the  glycol  will  prevent  the

liquid inside the piping from freezing.

▪ The  addition  of  glycol  applies  to  BOTH  cooling‑only

models (008BAVP) AND reversible models
(008BAVP),  and  is  independent  of  cooling
or  heating  operation.  ALWAYS  add  glycol  if  negative
outdoor temperatures are expected.

▪ The  required  concentration  might  differ  depending  on

the type of glycol. ALWAYS compare the requirements
from the table above with the specifications provided by
the  glycol  manufacturer.  If  necessary,  meet  the
requirements set by the glycol manufacturer.

▪ The  added  concentration  of  glycol  should  NEVER

exceed 35%.

▪ If the liquid in the system is frozen, the pump will NOT

be  able  to  start.  Mind  that  if  you  only  prevent  the
system from bursting, the liquid inside might still freeze.

▪ In  case  of  a  power  supply  failure  or  pump  failure,  and

NO glycol was added to the system, drain the system.

▪ When  water  is  at  standstill  inside  the  system,  the

system is very likely to freeze and get damaged.

The following types of glycol are allowed:

Ethylene glycol

;

Propylene glycol

, including the necessary inhibitors, classified as

Category III according to EN1717.

WARNING

Ethylene glycol is toxic.
