For 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 ows through the overow 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.

For the Installer

GENERAL

UKV 100 has several dierent areas of use.

UKV 100 can be used during external control of the heating system. The heat pump then charges UKV 100 with oating or xed condensing. The external control function controls the heat distribution from UKV 100 to the consumer.

If the ow to the heating system can be restricted using radiator thermostats, for example, install a UKV 100 as an intermediate tank. This ensures a secure ow for the heat pump.

UKV 100 also allows a greater ow 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 maximum cut-o pressure of 6 bar.

The working temperature is +4 to +95^ .

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^ (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.

All connections (including connections or holes that are used) must be insulated to minimise energy losses.

DOCKINGS

NOTE

These are outline diagrams. Actual installations must be planned according to applicable standards.

Volume increase as well as reduction of spikes

A UKV 100 is installed as a volume increaser in those cases the accumulator tank by loosening the connection where the system volume in the climate system is below (XL1) at the top of the accumulator tank. the minimum recommended volume for the heat pump. 2. Fill the vessel through the drain valve.

Volume and ow increaser and reduction in heat spikes

A UKV 100 is installed as a volume and ow 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 ow 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

Ripe 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 overow pipe must be the same size as the safety valve's. Route the overow pipe from the safety valve, sloping along its entire length, and ensure that it is frost- atof and well supported. The mouth of the overow pipe must be visible and not placed close to electrical components.

Ensure that incoming water is clean.

If uncertain, contact a plumber alternatively see applicable standards.

FILLING

Fill the accumulator tank as follows:

Case: vent the accumulator tank by loosening the connection to LW (XL1) at the top of the accumulator tank.

1. Fill the vessel through the drain valve.

2. 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 lled.
