components that prevent that the operation

pressure and the operation temperature

range are exceeded or go below a limit.

Install components for the limitation of

pressure and temperature in the system.

2.5.1 Avoiding excessive pressure

Appropriate safety valves that prevent

that the maximum operation pressure is

exceeded:

• Open not later than the maximum allowable

working pressure is reached.

 •Canconducttheoccurringvolumeow

(includingthemaximumpossiblerelling

volume) up to the 1.1-fold of the maximum

operation pressure;

 •Haveaprovenreliabilityorarecertied.

Do not narrow the inlet or outlet piping of

the safety valve.

2.5.2 Avoiding excessive temperature

Appropriate safety components:

• Guarantee that the operation temperature

range is not exceeded at any point of the

system;

• Are approved and tested on operation

safety.

Activate the pressure and temperature

safety devices and check them regular on

proper working.

2.6 Signs on the automat

The signs on the automat are part of the

3.3.1 Deaeration

Fordeaeratingthewater,thesystemwater

is drawn in via a bypass from the return line

of the system (H). The water is run through

aowregulator(G)andthestrainer(F)into

the deaeration tank (C). It is subjected to

a vacuum during the cyclic running of the

pump (D) and passed through a ring packing

(E).Asaresultoftheloweredpressure,and

thelargesurfaceoftheringpacking,air

dissoleves from the water.

Whenthepumpswitcheso,the

replenishingmediumowingintothetank

causes the pressure in the tank to increase

to the level of the system pressure so that

the air which has accumulated above the

water level is discharged via the vent. device

(A).Whilethepumpisrunning,thewater

quantity supplied into the tank is returned

via a bypass line to the return branch (B) of

the system.

• Fast deaeration mode (Fast = Turbo):

An interval during which the pump is run-

ning (vacuum is forming) alternates with an

interval during which the air is discharged

(pump is stopped).

• Normal deaeration mode:

An additional pause is added between

the end of the evacuation interval and

the starting of the pump. This additional

interval can be selected via a parameter

withinxedlimits.Uponexpiryofthe

deaerationinterval,thesystemchanges

tothenormaldeaerationmode,which

then takes place continuously. The
