AirStage AJY040LBLAH, En-6 5. PIPE INSTALLATION 5.1. Brazing CAUTION If air or another type of refrigerant enters the refrigeration cycle, the internal pressure in the refrigeration cycle will become abnormally high and prevent the unit from exerting its full performance. Pressure regulating valve Cap Nitrogen gas Brazing area Apply nitrogen gas while brazing the pipes. Nitrogen gas pressure: 0.02 MPa (= pressure felt suffi ciently on the back of your hand) If a pipe is brazed without applying nitrogen gas, it will create an oxidation fi lm. This can degra
En-7 CAUTION Hold the torque wrench at its grip, keeping it in a right angle with the pipe, in order to tighten the fl are nut correctly. Outer panel may be distorted if fastened only with a wrench. Be sure to fi x the elementary part with a holding wrench (spanner) and fasten with a torque wrench (refer to below diagram). Do not apply force to the blank
AirStage AJY040LBLAH, En-8 6. ELECTRICAL WIRING 6.1. The precautions of electrical wiring WARNING Wiring connections must be performed by a qualifi ed person in accordance with specifi - cations. The rated supply of this product is 50 Hz, 230 V of 1-phase, 2-wire. Use a voltage within the range of 198 to 264V. Make sure to perform earthing (grounding) work. Improper earthing (grounding) work can cause electric shocks. Before connecting the cables, make sure the power supply is OFF. Be sure to install an earth (ground) leakage breaker. Otherwise, it will cause electric shock or fi re. Select a breaker (Included with earth leakage circuit breaker) of appropriate capacity a
AirStage AJY040LBLAH, En-9 6.4. Transmission line CAUTION Caution when wiring cable: When stripping off the coating of lead wire, always use the exclusive tool such as a wire stripper. If there is no exclusive tool available necessarily, carefully strip the coat- ing by a cutter etc. so that the conductive wire is not damaged. If it is damaged, it may lead to an open circuit and a communication error. Pay attention to the following points while attaching wires on the terminal board. • Do not attach 2 wires on one side. • Do not twist wires. • Do not cross the wires. • Do not short
AirStage AJY040LBLAH, En-10 6.5.2 Wiring procedure • Remove the service panel.
