RZQG71~140L + RZQSG100~Y1B(9)

Split system air conditioners

4P327537-1 – 2012.08

11.4. Vacuum drying

To remove all moisture from the system, proceed as follows:

1

Evacuate the system for at least 2 hours to a target vacuum of –

100.7 kPa (= –1.007 bar). 

2

Check that, with the vacuum pump turned off, the target vacuum 
is maintained for at least 1 hour. 

3

Should you fail to reach the target vacuum within 2 hours or 
maintain the vacuum for 1 hour, the system may contain too 
much moisture. 

4

In that case, break the vacuum by pressurizing with nitrogen gas 
to a gauge pressure of 0.05 MPa (0.5 bar) and repeat steps 

1

 to 

3

 until all moisture has been removed. 

5

The stop valves can now be opened, and/or additional 
refrigerant can be charged (see 

"12. Charging refrigerant" on 

page 13

).

12. Charging refrigerant

12.1. 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

+

 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.

12.2. Precautions and general guidelines

When servicing the unit requires the refrigerant system to be 
opened, treatment and evacuation of refrigerant must be done in 
accordance with applicable 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 

"11. Leak test and vacuum drying" on 

page 12

).

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.

On this model it is not necessary to charge additionally if the piping 
length 

30 m.

For RZQG units only: 

 

If the piping length <5 m: See 

"12.5. Total charging weight of the 

refrigerant (after a leak, etc.)" on page 15

.

INFORMATION

After opening the stop valve, it is possible that the pressure 
in the refrigerant piping does not rise. This might be 
caused by e.g. the closed state of the expansion valve in 
the outdoor unit circuit, but does not present any problem 
for correct operation of the unit.

CAUTION

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

WARNING

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.

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

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.
