3. Installation Process Embedding the Tubing and Wiring 3-1. Do not connect tubes to locations that are embedded. Be sure to bind refrigerant tubing and inter-unit cables together with vinyl tape. The power cable must be obtained on-site. (φ2.0: Less than 15 m / φ2.6: Less than 20 m / φ3.5: Less than 26 m) Be sure to apply the provided labels to both ends of the inter-unit cables to prevent miswiring. -

Page 11: Refrigerant Operation System
3-10. Refrigerant Operation System When the air conditioner is turned ON, the compressor starts to work. The compressor absorbs low-temperature and low-pressure refrigerant from the evaporator; the refrigerant is then compressed into high-temperature and high- pressure refrigerant gas and goes into the condenser (COMPRESSION). This high-temperature and high-pressure refrigerant gas is condensed into liquid refrigerant;... -
Page 12: Air Purging
4. Air Purging Air and moisture remaining in the refrigerant system have undesirable effects as indicated below. There- fore, they must be purged completely. pressure in the system rises operating current rises Service Manifold gauge valve on cooling efficiency drops (special for R410A) narrow High-pressure valve... - Page 13 (4) With the “Lo” knob of the manifold valve open and high-pressure valve (“Hi”) closed completely, run the vacuum pump. Run the pump until the pres- sure is –101 kPa (–76 cmHg). The operation time for the vacuum pump varies with tubing length and the capacity of the pump.
