This set contains a safety valve (A) and instructions (B).

Application

• The safety valve can be used in a closed heating or cooling system. (glycol max. 50%)

• Only use the valve in a dry and frost-free location.

• Min./Max. system temperature: -10 ºC/+120 ºC

Safety

Check whether the maximum load and the opening pressure that are indicated on the valve match

the values of the system.

The opening pressure has a pre-set value; do not change this!

The following points are important to ensure a good operation of the valve and the safety of the

installation.

• Only have the installation carried out by qualiﬁ ed personnel. Comply with local legislation and

guidelines.

• Fit the valve to the installation and use for this the special spanner indentations (C).

• Carry out the installation on a system that is not under pressure.

• Only ﬁ t the valve once the pipes have been thoroughly ﬂ ushed and brought under pressure.

• Do not weld or solder in the vicinity of the valve.

• Fit the valve in the supply pipe close to the boiler.

• Pay attention to the arrow that indicates the ﬂ ow direction.

• Do not place a circuit breaker (D) between the boiler (E) and the valve.

• The diameter of the inlet and outlet pipes may not be smaller than the inlet and outlet con-

nections on the valve.

• Ensure there is a free outlet opening (circuit breaker installation) under the fall and directly

connected to the outlet of the valve (e.g. Flamco funnel F)

• Beware of steam from the exhaust: it can cause burns!

• Never ﬁ t the valve with the inlet or outlet pointing upwards (G-H).

• Check the valve annually using valve lights and ﬂ ush through the valve thoroughly. Seal the

valve afresh.

• If the valve regularly blows off steam during use, consult the installation specialist.

Release the pressure from the system. There is a danger of burns! Hot water can ﬂ ow out of the

system. Remove the valve.

Environment

Comply with local legislation when disposing of the valve.
