We cannot accept any liability for any heat 1 Notes on the documentation pump malfunctions which have been caused by the heat source system, the heating system, Read this manual carefully before incorrect adjustment of the regulation and con- trol elements or due to natural hazard events you begin to commission/adjust the (lightning, flooding,...).
Under normal operating conditions, the heat The heat pump is filled with the non- pump heats the storage tank from +10° C to flammable refrigerant R 134a. +52° C within 9 hours. Always use protective clothing and protective eyewear when working on 4.2 Delivery the refrigerant circuit! The heat pump is delivered ready to install, i.e.
No light fittings or pipework are to be located When installing air intake and outlet ducting above the heat pump. (ventilation system) the minimum diameter of the ducting tubes must be 160 mm (spiral tube The tank should be located as close as possible 160).
If necessary, a pressure reducing valve and a Installation: with heating heat pump filter should be installed in the inlet pipework. Air ducting: Air intake from damp rooms (air wake required by means of intake openings e.g. slats in doors) or partially from installation room, The hot water tank must be fully exhaust to outside air.
For heating boilers with sliding mode control the Ochsner will accept no liability for malfunctions boiler sensor for the heating boiler control can caused by wrongly-sized safety components! be fitted in the existing 1/2" immersion sleeve in the heat pump tank. The power supply to the We recommend running the 230 V/50Hz supply charge pump is from the boiler control, which wiring via its own protective circuit, so that if...

6 Operation The heat pump is monitored and regulated by a digital controller. The user has for this display units and operating elements at his disposal, via which the data can be set and called up. The user can set an “operation selection“ as well as “set values“ OPERATION SELECTION Heat pump AUTOMATIC...
6.1 Settings Switching heat pump ON/OFF LED off: Heat pump switched off LED blinks: Heat pump running LED on: Heat pump switched off – Standby operation. The set value S1 has been reached See Point. 3 The compressor stand-by interval (20 minutes) is activated Keep button pressed for min.
6.2 Setting the Legionella function A one-off DHW heating, which will be started at adjustable intervals (days) t1, can be pro- grammed into the control. Here, the DHW will be heated by the heat pump up to a set value S2. Should the set value not be reached within 4 hours, the heat-up cycle will be stopped by the pro- gram.
