The inspection must be carried out by a suitably qualified person. DateSignatureNotesDescription

Heating medium (page 14) Shut off valves Safety valve 11UKV 100 | ENFor the User MAINTENANCE The safety valve in the system where the accumulator tank is installed must be inspected regularly (about four times a year) to prevent blockages. To inspect the valve, open the safety valve manually and check that water flows through the overflow pipe. If this does not happen then the safety valve is defective and must be replaced. SERVICE For service, contact the installer. Serial number (PZ3) (14 digits) and installation date should always be stated. Only replacement parts supplied by NIBE may be used. UKV 100 | EN12For the Installer GENERAL UKV 100 has several different areas of use. UKV 100 can be used during external control of the heating system. The heat pump then charges UKV 100 with floating or fixed condensing. The external control function controls the heat distribution from UKV 100 to the consumer. If the flow to the heating system can be restricted using radiator thermostats, for example, install a UKV 100 as an intermediate tank. This ensures a secure flow for the heat pump. UKV 100 also allows a greater flow to the heating system than across the heat pump. In some installations, so-called heating clicks occur as a result of movements during changes in temperature. To eliminate temporary changes in temperature, and thereby prevent heating clicks, install a UKV 100 after the heating installation. UKV 100 can also be used to increase the system volume and thereby prevent malfunctions. The accumulator tank consists of a condensation-insulated steel vessel with polyurethane insulation. Outer cladding in white, powder-coated sheet metal with ends of durable plastic. The accumulator tank is designed and manufactured for a maximum cut-off pressure of 6 bar. The working temperature is +4 to +95 °C. TRANSPORT UKV 100 should be transported and stored in the dry. ASSEMBLY The accumulator tank must be installed in a dry area at a temperature that does not drop below 0 °C (frost-free). MOUNTING UKV 100 has to be installed vertically suspended on the wall. First install the enclosed mounting bracket on the wall, then suspend UKV 100 from the bracket. SUPPLIED COMPONENTS Suspension bracket.

DOCKINGS NOTE These are outline diagrams. Actual installations must be planned according to applicable stand- ards. Volume increase as well as reduction of heat spikes A UKV 100 is installed as a volume increaser in those cases where the system volume in the climate system is below the minimum recommended volume for the heat pump. Volume and flow increaser and reduction in heat spikes A UKV 100 is installed as a volume and flow increaser in those cases where the system volume in the climate system is below the minimum recommended volume for the heat pump and/or the flow is restricted without control. Volume increase as well as reduction of heat spikes A UKV 100 is installed as a volume increaser in those cases where the system volume in the climate system is below the minimum recommended volume for the heat pump. PIPE INSTALLATION Pipe installation must be carried out in accordance with current norms and directives. The drain valve is installed on the heating system’s return line (XL2). The system where UKV 100 is installed must be supplied with a safety valve of max. 6 bar (0.6 MPa). The overflow pipe must be the same size as the safety valve's. Route the overflow pipe from the safety valve, sloping along its entire length, and ensure that it is frost- proof and well supported. The mouth of the overflow pipe must be visible and not placed close to electrical compon- ents. Ensure that incoming water is clean. If uncertain, contact a plumber alternatively see applicable standards. FILLING Fill the accumulator tank as follows:

1. Vent the accumulator tank by loosening the connection

(XL1) at the top of the accumulator tank.

2. Fill the vessel through the drain valve.

3. When only water comes out of the connection (XL1) (an

air-water mixture emerges initially), the connection can be closed and the accumulator tank is filled.
