Good to know about NIBE f2026 Principle of operation This is a simplified version of how it works. The outdoor air is drawn into the heat pump and meets a closed system. The system contains a refrigerant with the capacity to turn into gas at a very low temperature. Under high pressure, a compressor considerably increases the temperature of the refrigerant, which is now gaseous. Then, using a condenser, the heat is transferred to the house s heating system, while at the same time the refrigerant reverts to liquid form, ready to turn into gas once more and to collect new heat energy. Maintenance F2026 is equipped with control and monitoring equipment, however some exterior maintenance is still necessary. Make regular checks throughout the year that the grilles are not clogged by leaves, snow or anything else. Strong wind combined with heavy snowfall can block the intake and exhaust air grilles. Make sure that there is no snow on the grilles. The condensation water trough and drain pipe may require cleaning from leaves or similar during the year. If necessary the outer casing can be cleaned using a damp cloth. Care must be exercised so that the heat pump is not scratched when cleaning. Avoid spraying water into the grille or the sides so that water penetrates into F2026. Prevent F2026 coming into contact with alkaline cleaning agents. Transport and storage F2026 should be transported and stored vertically. Control F2026 is equipped with an integrated electronic controller that handles all functions necessary for heat pump operations. It controls defrosting, stop at max/min temperature, connection of the compressor heater as well as enabling the heater for the drip pan, monitoring of motor protection and pressure switches. The number of starts and the operating time can also be read. The integrated controller is set during installation and can be used during a service. Under normal operation conditions the home owner does not need to have access to the controller. F2026 has an integrated electronic return line sensor that limits the return temperature. F2026 is switched on/off via signals from other control equipment or a thermostat. If F2026 is to be controlled using the accessory SMO 10 or VVM 300 then relevant procedures are described in respective instructions. SMO 05, SMO 10 and VVM 300 communicate with F2026, which means that all settings and measurement values from F2026 can be adjusted and read on SMO 05/SMO 10/VVM 300. Sound pressure levels F2026 is usually positioned next to a house wall, which gives directed sound distribution that should be considered. Accordingly, you should always attempt to find a placement on the side that faces the least sound sensitive neighbouring area. The sound pressure levels are further affected by walls, bricks, differences in ground level, etc and should therefore only be seen as guide values. F2026 works in summer with a low fan speed and at other times with a high fan speed (does not apply to F2026-6 kw that only has one fan speed).

installation F2026 can be connected in several ways. Below are some of the most common alternatives. Further system solutions are available in respective assembly instructions for the accessories used. NIBE F2026 + NIBE VVM 300 system solution F2026, together with VVM 300, creates a complete heating and hot water unit. VVM 300/EVP510 is equipped with a control box that currently makes it the most economical operator, both for the integrated immersion heaters (max 13.5 kw) and compressor operation in F2026. VVM 300 comes complete with an automatic by-pass, three way valve, circulation pump, speed controlled charge pump and safety equipment. With VVM 300, pool heating is possible as well as an extra shunt group, i. e. two heating systems with different flow temperatures. VVM 300 is designed for simple connection to F2026. NIBE F2026 + NIBE SMO 10 system SMO 10 controls up to nine F2026 (of which one can be used for hot water), additional heat, circulation pumps, shuttle valve, etc. F2026 HP1 prioritises hot water charging via a shuttle valve. If there is no hot water or heating demand, F2026 is available for pool heating. F2026 runs with floating condensing towards the heating system.if F2026 cannot handle the heating demand, additional heat is connected. The fan works in stage 1 or stage 2 depending on the outdoor air temperature. In cases where the system volume in the radiator circuit is below 20 l/kw (heat pump output at 7/45 C) and/or the radiator flow is choked uncontrolled, a buffer vessel is installed as a volume and flow increaser. RC SMO 10 10 Oil/Gas/Electrical Oljepanna alternativt elpanna boiler med shunt F2026 F20XX POOL VVM 300 F2026 VP2 NIBE F2026 + SMO 05 system SMO 05 is an intelligent control module that, together with the air/water heat pump and existing heating and hot water equipment, creates a complete unit. With the SMO 05, it is possible to position the display unit in a suitable position for the end user. For example, in the hall or kitchen. The controller has full intelligence and is part of a new NIBE generation controller platform. Which domestic hot water cylinder to use, you will find in the product leaflet for SMO 05. Electrical addition External addition Gas boiler Buffer Buffel vessel F2026 VP1 VPA 300/200 Hot water control VST 11, VST 20 (accessory) This accessory allows the heat pump F2026 with SMO 10 to prioritise hot water charging on systems with floating condensing. This also requires a hot water accumulator, for example, NIBE VPA or NIBE VPB as well as a thermostat. When the hot water sensor for hot water temperature is connected, the control system is automatically activated for the charging functions. When there is a demand for hot water, the heat pump gives this priority and devotes its entire heat pump output to water heating. No room heat is produced in this mode. F2026 NIBE F2015-6, -8, -11 6 NIBE F2026 Controller SMO 05 Room unit NIBE VPB 200N Existing boiler This system set up is often used to back up an existing heating system. The built-in controller in the outdoor unit can work with a thermostat. This installation make use of existing equipment and thus keep installation costs down. However, the energy savings that can be achieved are not as high as with the three other systems described.
Installation Inspection of the installation Current regulations require the heating installation to be inspected before it is commissioned. The inspection must be carried out by a suitably qualified person and should be documented. The above applies to closed heating systems. If the heat pump is replaced, the installation must be inspected again. Installation and positioning Position F2026 outdoors on a firm and level surface that can take the weight, preferably a concrete foundation. If concrete slabs are used these should lie on tarmac or gravel. The concrete foundation or slabs must be positioned so that the lower edge of the evaporator is at the level of the average local snow depth, although a minimum of 300 mm above ground level. F2026 should not be positioned next to sensitive walls, for example, next to a bedroom. Also ensure that the placement does not inconvenience the neighbours. F2026 must not be placed so that recirculation of outdoor air can occur. This causes lower output and impaired efficiency. Large amounts of condensation water as well as melt water from defrosting can be produced. Condensation water must be led off to a drain or similar. Care must be exercised so that the heat pump is not scratched during installation. Do not place F2026 directly on the lawn or other non solid surface. If there is a risk of roof slides a protective roof or similar should be installed over the heat pump, pipes and wiring. The KVR 10 accessory should be used to guarantee function. That part of the pipe (KVR 10) that is not frost protected must be heated by the heating cable to prevent freezing. Route the pipe (KVR 10) downward from F2026. The drain of the condensation water pipe must be positioned at frost free depth or indoors (subject to local rules and regulations). The installation must be equipped with a water seal where air circulation can occur in the condensation water pipe. Pipe installation Condensation water pipe KVR 10 (accessory) Pipe installation must be carried out in accordance with current norms and directives. F2026 works up to a return temperature of approximately 50 C and an outgoing temperature from the heat pump of approximately 58 C. When F2026 is not equipped with shutoff valves on the water side these must be fitted to facilitate future service. Pipe connection (heating medium) F2026 can be connected to the heating system see the section Docking or according to one of the system solutions that can be downloaded from NIBE s website www.nibe.eu. The heat pump must be vented by the upper connection (70, VB-out) using the venting nipple on the enclosed flexible hose. The supplied particle filter must be installed before the inlet, i.e. the lower connection (71, VB-in) on F2026. All outdoor pipes must be thermally insulated with at least 19 mm thick pipe insulation. The charge pump must be operational, even if F2026 is not running, to prevent damage due to freezing. Alternatively, the heat pump is connected to an intermediate circuit with a heat exchanger, pump and water with anti-freeze. Shutoff and drain valves are fitted so that F2026 can be emptied in the event of prolonged power failures. The supplied flexible hoses act as vibration dampers. The flexible hoses are fitted so a slight bend is created, thus acting as vibration damping. Condensation water collection The integrated condensation water trough is used to collect and lead away most of the condensation water from the heat pump. The condensation water (up to 50 litres/24 hrs) collected in the trough should be routed via a pipe (KVR 10) to an appropriate drain, it is recommended that the shortest outdoor stretch possible is used.

Installation Recommended alternatives Stone caisson Drain indoors Frost Frostfritt free djup depth Electrical installation The routing of cables for heavy current should be made out through the cable glands on the heat pump s left-hand side, seen from the front (100) and signal cables from the rear (102) F2026 does not include an isolator switch on the incoming electrical supply. The heat pump s supply cable must be connected to a circuit-breaker with at least a 3 mm breaking gap. When the building is equipped with an earth-fault breaker the heat pump should be equipped with a separate one. Incoming supply must be 400 V 3NAC 50Hz via distribution boards with fuses. The terminal blocks can be accessed by removing the 2 screws for the plastic covers and electrical box screws. NOTE! The electrical installation and service must be carried out under the supervision of a qualified electrician. Electrical installation and wiring must be carried out in accordance with the stipulations in force. If the house has a cellar the stone caisson must be positioned so that condensation water does not affect the house. Otherwise the stone caisson can be positioned directly under the heat pump. The outlet of the condensation water pipe must be at frost free depth. The condensation water is lead to an indoor drain (subject to local rules and regulations). Route the pipe downward from F2026. The condensation water pipe must have a water seal to prevent air circulation in the pipe.
