REFRIGERANT

Important information regarding the refrigerant used

This product contains fluorinated greenhouse gases covered by the
Kyoto Protocol. Do not vent gases into the atmosphere.

Refrigerant type:

R410A

GWP

(1)

 value:

1975

(1)

 GWP = global warming potential

Please fill in with indelible ink,

 the factory refrigerant charge of the product,

 the additional refrigerant amount charged in the field and

+

➁ 

the total refrigerant charge

on the fluorinated greenhouse gases label supplied with the product.

The filled out label must be adhered on the inside of the product and
in the proximity of the product charging port (e.g. on the inside of the
service cover).

To avoid compressor breakdown. Do not charge the refrigerant
more than the specified amount.

This outdoor unit is factory charged with refrigerant and
depending on pipe sizes and pipe lengths some systems require
additional charging of refrigerant. See "Calculating the additional
refrigerant charge" on page 11.

In case re-charge is required, refer to "Complete recharging" on
page 11.

Precautions and general guidelines

This unit requires additional charging of refrigerant according to
the length of refrigerant piping connected at the site.

Make sure to charge the refrigerant in liquid state to the liquid
pipe. Since R410A is a mixed refrigerant, its composition
changes if charged in its gaseous state and normal system
operation would then no longer be assured.

Before charging, check whether the refrigerant cylinder has a
syphon attached or not and position the cylinder accordingly.

NOTE

National implementation of EU regulation on certain
fluorinated greenhouse gases may require to provide
the appropriate official national language on the unit.
Therefore, an additional multilingual fluorinated
greenhouse gases label is supplied with the unit.

Sticking instructions are illustrated on the backside of
that label.

Refrigerant cylinder and 
manifold for charging

When servicing the unit requires the refrigerant
system to be opened, treatment and evacuation of
refrigerant must be done in accordance with relevant
local and national legislation.

Refrigerant can not be charged until field wiring has
been completed.

Refrigerant may only be charged after performing the
leak test and vacuum drying (see "Leak test and
vacuum drying" on page 9).

When charging a system, care shall be taken that its
maximum permissible charge is never exceeded, in
view of the danger of liquid hammer.

Charging with an unsuitable substance may cause
explosions and accidents, so always ensure that the
appropriate refrigerant (R410A) is charged.

Refrigerant cylinders shall be opened slowly.

Always use protective gloves and protect your eyes
when charging refrigerant.

DANGER

When the power is on, please close the front panel when
leaving the unit unattended.

Filling using a cylinder 
with a siphon attached
Charge the liquid refrigerant 
with the cylinder in upright 
position.

Filling using a cylinder 
without a siphon attached
Charge the liquid refrigerant 
with the cylinder in up-side-
down position.
