General information

Thermostatic radiator valves control the room temperature by

modifying the flow of hot water through the radiator. As the heat

demand is often very low (especially during transition periods), the

valves are opened by the thermostat to only a small amount. As

a result, flow noises may occur due to high differential pressures.

To prevent these noises, differential pressure independent

thermostatic valves, such as «AQ», or devices influencing the

differential pressure should be used; for example adjustable

circulation pumps, automatically working differential pressure

regulators or differential pressure relief valves.

It is recommended to adjust the flow temperature to the

outside temperature, preferably by using a weather guided flow

temperature control.

Further information can be obtained from the manual «User

instructions» and the technical data sheets «Thermostats»

and «Thermostatic radiator valves».

Installation of the valve

The radiator valve is to be installed so that the thermostat is in a

horizontal position and a good circulation of air is guaranteed. If

this is not possible, a thermostat with remote sensor or remote

control should be used. It is most important that the capillaries

are not kinked or flattened.

The radiator valve is installed in the supply pipe to the radiator,

with the flow in the direction of the arrow.

When using compression fittings, the thread of the fitting and

the compression ring are slightly oiled at works. Do not use any

additional lubricant! Do not allow the oil or lubricant to come into

contact with the EPDM valve disc. EPDM is not oil resistant.

When using compression fittings for thermostatic valves with

female threaded connection (only possible for sizes DN 10,

DN 15 and DN 20), the «Ofix» compression fittings are to be used

to guarantee a perfect sealing function between the pipework

and the thermostatic valve.

It is important that the pipes are cut to the correct length at a right

angle to the centre line. The ends of the pipe must be free from

burrs and undamaged.

Installation instructions for the specialised installer

When using thin walled and very soft pipes, reinforcing sleeves

have to be used. The reinforcing sleeve supports the pipe and

provides the strength to enable the necessary compression.

Reinforcing sleeves cannot be used for pipes with welded

seams. The recommendations of the pipe manufacturers have

to be observed in any case. If necessary, a practical test has to

be carried out.

The special screwed fittings «Cofit S» or press fittings «Cofit

P/PD/PDK» may be used for the Oventrop composition pipe

«Copipe». The installation instructions supplied with the fittings

must be observed.

When choosing the operating fluid, the latest technical status

has to be considered (e.g. VDI 2035 — Avoidance of damage to

hot water heating systems).

All radiators and pipework must be flushed thoroughly to

prevent any problems caused by welding beads and dirt.

When converting old heating systems, it is recommended that

a plastic strainer should be fitted at the inlet port of all radiator

valves.

Do not fit the thermostat until all building work has been

completed. During the construction period, the valve can be

operated with the protection cap. The cap is not to be used for

permanent shut-off of the valve against system pressure (e.g.

while the radiator is removed). In this case protect the valve

outlet with a metal cap.

Installation of the thermostat

To ensure an easy installation, the handgrip must be opened to

the maximum position (figure «5»). In this position, the collar nut

(«Uni LH») or the squeeze connection («Uni LD») of the thermostat

may be easily fitted to the valve body.

Turn the thermostat so that the indicator mark is facing up. Hold

in this position and tighten the collar nut without using excessive

force.
