Refilling the refrigerant

Check the type of refrigerant to be used on the machine nameplate.

Precautions when adding R410A
Fill from the gas pipe in liquid form.

It is a mixed refrigerant, so adding it in gas form may cause the refrigerant composition to change, preventing normal operation.
1) Before filling, check whether the cylinder has a siphon attached or not. (It should have something like “liquid filling siphon 

attached” displayed on it.)

• Be sure to use the R410A tools to ensure pressure and to prevent foreign objects entering.

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 piping work

7-1 Cautions on pipe handling

1) Protect the open end of the pipe against dust and moisture.
2) All pipe bends should be as gentle as possible. Use a pipe bender 

for bending.

7-2 Selection of copper and heat insulation materials

When using commercial copper pipes and fittings, observe the following:
1) Insulation material:  Polyethylene foam 

Heat transfer rate:  0.041 to 0.052W/mK (0.035 to 0.045kcal/(mh •°C))
Refrigerant gas pipe’s surface temperature reaches 110°C max.
Choose heat insulation materials that will withstand this temperature.

2) Be sure to insulate both the gas and liquid piping and to provide insulation 

dimensions as below.

3) Use separate thermal insulation for gas and liquid refrigerant pipes.

O.D. 12.7mm

I.D. 8-10mm

Minimum bend radius

Thickness 10mm Min.

40mm or more

30mm or more

Thickness 0.8mm (C1220T-O)

Filling a cylinder with an attached siphon

Stand the cylinder upright when 

filling.

There is a siphon pipe inside, so the 

cylinder need not be upside-down to 

fill with liquid.

Turn the cylinder upside-down 

when filling.

Filling other cylinders

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 refrigerant charge label supplied with the product.

Important information regarding the refrigerant used
