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.

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.

Precautions for compressor

WARNING

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.

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

-equivalent) 

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  The  GWP  value  mentioned  in  the manual might be outdated (i.e., based on the 3rd IPCC Assessment Report).
