Notes: 1. Specifications are based on the following RWEYQ10TYM RWEYQ12TYM RWEYQ12TYM conditions: RWEYQ12TYM RWEYQ12TYM RWEYQ12TYM • Cooling: Indoor temp.: 27ºCDB, 19ºCWB / inlet 3-phase 4-wire system, 380-415 V/380 V, 50/60 Hz water temp.:30ºC, Equivalent piping length: 7.5 m, Height difference: 0 m. 305,000 324,000 345,000 • Heating: Indoor temp.: 20ºCDB / inlet water 89.5 95.0 101 temp.: 20ºC, Equivalent piping length: 7.5 m, 345,000 365,000 386,000 Height difference: 0 m. • Sound level: Anechoic chamber conversion 101 107 113 value, measured at a point 1 m in 18.2 20.1 22.0 front of the unit at a height of 1.5 m. 19.1 21.3 23.6 During actual operation, these lvory white (5Y7.5/1) values are normally somewhat (1,000 × 780 × 550) × 3 higher as a result of ambient conditions and oil recovery mode. Hermetically sealed scroll type When there is concern for noise to 3.7 × 2 + 4.7 3.7 + 4.7 × 2 4.7 × 3 the surrounding area such as 19.1 (Flare) residences, we recommend investigating the installation 34.9 (Brazing) location and taking soundproofing 28.6*2, 34.9*3 (Brazing) measures. 2. This unit cannot be installed in the outdoors. (PT1 1/4B) × 3 internal thread Install indoors (Machine room, etc). (PT1 1/4B) × 3 internal thread 3.
