SAFETY PRECAUTION 3-1. ALWAYS OBSERVE FOR SAFETY Before obtaining access to terminals, all supply circuits must be disconnected. 3-2. CAUTIONS RELATED TO NEW REFRIGERANT Cautions for units utilizing refrigerant R410A Use new refrigerant pipes. Do not use refrigerant other than R410A. If other refrigerant (R22 etc.) is used, chlorine in refrige- rant can cause deterioration of refrigerant oil etc.
Page 4 [2] Additional refrigerant charge When charging directly from cylinder · Check that cylinder for R410A on the market is syphon type. · Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.) Unit Gravimeter [3] Service tools Use the below service tools as exclusive tools for R410A refrigerant.
