Notes
(1) With option kit *KHBDP installed: Height = XXX mm
(2) DB/WB 7ºC/6ºC - LWC 35ºC (DT=5ºC)
(3) The sound pressure level is measured via a microphone at a 1m distance from the unit. It is a relative value, depending on the distance and acoustic environment.
(4) The sound pressure level mentioned is maximum possible value inside operation range of unit
(5) 15ºC-25ºC: BUH only, no heat pump operation = during commisioning
(6) Including piping + PHE + back-up heater; excluding expansion vessel
(7) Value mentioned is connection after ball valves, Connection at unit is G1-1/4 FEMALE
(8) See separate drawing for operation range
(9) \> 50ºC BSH only, no heatpump operation
(10) BUH 3V/9W can only operate at flow \> 12/15 l/min
(11) Refer to operation range for detail for differences between *RHQ* and *RLQ* models
(12) PED unit category: Art3§3: excluded from scope of PED due to article 1, item 3.6 of 97/23/EC
