Charging refrigerant
Check the type of refrigerant to be used (on the machine nameplate).
Fill from the gas pipe in liquid form.
1-1. Charging additional refrigerant
• If the total length of refrigerant piping exceeds 10m, add refrigerant.
• Subtract 10m from the overall length and write the result in column.
20g x
1-2. Completely recharging refrigerant
The total amount that must be added is the amount listed on the machine nameplate and the amount of the additional refrigerant.
Important information regarding the refrigerant used
This product contains fluorinated greenhouse gases.
Do not vent gases into the atmosphere.

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

to 2 decimal places)
on the refrigerant charge label supplied with the product.
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.
NOTICE
In Europe, the greenhouse gas emissions of the total refrigerant charge in the system (expressed as tonnes CO
is used to determine the maintenance intervals. Follow the applicable legislation.
Formula to calculate the greenhouse gas emissions:
GWP value of the refrigerant × Total refrigerant charge [in kg] / 1000
Use the GWP value mentioned on the refrigerant charge label. This GWP value is based on the 4th IPCC Assessment
Report. The GWP value mentioned in the manual might be outdated (i.e., based on the 3rd IPCC Assessment Report).
Precautions for compressor
Electric shock hazard
• Use this compressor on a grounded system only.
• Turn power OFF before servicing.
• Replace terminal cover before applying power.
Injury hazard
• Wear protective goggles.
Explosion or fire hazard
• Use tubing cutter to remove compressor.
• Do NOT use torch. System contains refrigerant under pressure.
• Do NOT drive under air or vacuum condition.
• Use only approved refrigerants and lubricants.
Burn hazard
• Do NOT touch with bare hands during or immediately following operation.
