369622 09.09 Further examples of applications (mixer heating circuits, connection to solar heating system, etc.) may be found in the software and hydraulics manuals. Please note: The heat pump must be protected by a circuit breaker with an allphase switch (not by 3 individual fuses)!! The diagram on the right must be used. Local regulations must be observed.
Technical information Prior to installation 4. Prior to installation 4.1 Transport Upon delivery of the heat pump, it must be checked for transport damage and complete delivery according to the order confirmation. Where material is damaged or missing, the transport company must be immediately notified in writing. Care must be exercised during transport, set-up and preparation or when handling the unit so as not to cause damage.
Prior to installation The AMBIflo heat pump is very quiet in operation, however, in the knowledge that noise perception is very subjective, the pump should not be set up near a window, bedroom or leisure site (terrace, swimming pool deck, etc.). A sufficient distance to the adjoining properties should be observed. It is not recommended to set up the pump in a wall niche (possible echo or air blockage).
4.3 Outdoor installation Base The base should project approx 50 mm beyond all sides of the heat pump and be sufficiently high enough to account for snow and water ingress. Prior to installation Fig. 3: Dimensions of air inlet 1 2 Heating flow Ø 1" (16), Ø 1¼" (AMBIFLO 20) flexible. The hydraulic and electrical connections can all be located on the left or right of the heat pump. Heating flow Ø1" (16), Ø 1¼" (20) flexible.
Fig 4. Alternative condensation water outlet via drainage shaft is possible. Drainage pipe insulation at least 3 cm. Minimum size of drainage shaft H = 50 cm W = 50 cm D = 50 cm Water-tight empty pipe (plastic) to be installed 800 to 1000 mm below the ground by the customer, at a gradient of 2% towards the building. Only 45° brackets should be used. 4.
Prior to installation Optimised defrosting When the outdoor temperature drops below 7°C, frost will form on the air/heat exchanger's evaporator. This will result in the formation of ice and will consequently reduce heat exchange and thus the degree of efficiency of the heat pump. To remove this frost or ice, the evaporator must be defrosted.

Prior to installation Fig 7: Connection plan Please note: The heat pump must be protected by a circuit breaker with an all-phase switch (not by 3 individual fuses)!! The diagram on the right must be used. Customer's control panel Local regulations must be observed. AMBIFLO 16B The AMBIFLO16B power supply circuit diagram in the installation instructions must be taken into account.
Assembly 5. Assembly 5.1 Heat pump roof Pre-rolled opening for air/water heat pump installed outdoors There is a pre-rolled opening (1) at the bottom of the pump system, behind the electrical control panel, through which the pipes pass into the ground. Where a heat pump is installed outdoors, we recommend that you use this duct. The heating pipes, the condensate connection and the electrical cables all pass through this opening.
Assembly 5.2 Weather protection grid The two weather protection grids (on the inlet and outlet side) must be fixed to the interior frame of the cover. This can be done with the aid of an Allen key (Size 3) or a battery-driven screw driver. The outlet side may be on the left or right. The outlet grid must be used when the system is installed outdoors. Where the weather protection grid is to installed (outdoor installation), the air sensor (5) must be pulled out of the grid. Fig. 9 25 369622 09.
Installation 6. Installation All transport safety devices must be removed before operation. The regulations and diagrams must be carefully followed. The accessories must be installed by an expert (heating system technician) according to the instructions for installation included. The noise emanating from a heat pump of this type is very low, due to the three-step, sound-absorbing bearings used for the movable components and the sound insulation cover.
Installation Fig. 10 6.2 Accumulator When the heat pump is operated with a buffer storage tank, Andrews Water Heaters accumulators of the Solar series are recommended. 6.
Installation The outdoor temperature sensor is enclosed. See circuit diagram for connection instructions. Cable replacement All electrical cables, with the exception of the main power supply cable, must be replaced with Andrews Water Heaters special cables, where required. Only cables of the type H05VV-F are to be used when replacing the main power supply cable. Contact safety Once the AMBIFLO has been opened, the cover panels must be replaced, using the appropriate screws, to ensure contact safety.

Commissioning 7. Commissioning Danger! An accredited heating technician must commission the system! The heating technician will check the leak-tightness of the pipes, the proper function of all control and safety devices and measure the combustion values.
Commissioning Where commissioning is requested without all these conditions being met, Andrews Water Heaters will take no responsibility for any system operating problems. The system is then operated at the user's own risk and responsibility. The following points must be observed or checked: 1. 2. 3. 4. 5. 6. - Hydraulic circuits: Check concurrence with the documentation provided. Check the electrical connections and fuses. Check the terminal allocation at the heat pump control unit.
Commissioning 7.5 Instructing the operator Instruction The operator must be duly instructed in the operation of the heating system and the function of the protective devices. In particular, the following must be pointed out to him: - The state of the cover is to be checked. The fastening of the outer cover is to be checked. To protect the paintwork, no objects should be leaned against or placed on top of the device.

Programming Indoor effect (750, 1050, 1350) The feed temperature is calculated as a function of the outside temperature using the heating curve. This control type assumes that the heating characteristic is set correctly, because with this setting, the controller does not make use of the indoor temperature.
Programming Fast heating-up (770, 1070, 1370) The fast-heating-up function becomes active when the indoor target value switches from protection level or reduced level to comfort level. During fast-heating-up function, the indoor target value is increased by the value set here. The actual indoor temperature increases to the new threshold in a relatively short period, due to this setting.
