6. REFRIGERANT PIPING WORK 〈For refrigerant piping of outdoor units, see the installation manual attached to the outdoor unit.〉 〈Execute thermal insulation work completely on both sides of the gas piping and the liquid piping. Otherwise, a water leakage can result sometimes.〉 (When using a heat pump, the temperature of the gas piping can reach up to approximately 120°C, so use insulation which is sufficiently resistant.) 〈Be sure to check the type of R410A refrigerant to be used before doing any work. - Page 13 Not recommendable but in case of emergency You must use a torque wrench but if you are obliged to install the unit without a torque wrench, you may follow the installation method mentioned below. After the work is finished, make sure to check that there is no gas leak. When you keep on tightening the flare nut with a spanner, there is a point where the tightening torque suddenly increases.

Page 16: Drain Piping Work
7. DRAIN PIPING WORK (1) Rig drain piping • As for drain work, perform piping in such a manner that water can be drained properly. • Employ a pipe with either the same diameter or with the diameter larger (excluding the raising section) than that of the connecting pipe (PVC pipe, nominal diameter 25 mm, outside diameter 32 mm). - Page 17 <PRECAUTIONS FOR DRAIN RAISING PIPING> • Install the drain raising pipes at a height of less than 675 mm. The drain pump of this unit has a high delivery flow rate. Therefore, the higher the drain raising height is, the lower the sound of draining will be. For this reason, a minimum drain raising height of 300 mm is rec- ommended.
