CALEFFI DISCAL 551 Series Guía del usuario

Function

Air separators are used to continuously remove the air contained

in the hydronic circuits of heating and cooling systems. The air

discharge capacity of these devices is very high. They are capable

of removing automatically all the air present in the system down to

micro-bubble level.

The circulation of fully de-aerated water enables the equipment to

operate under optimum conditions, free from any noise, corrosion,

localized overheating or mechanical damage. Micro-bubbles, fusing

with each other, increase in volume (get larger) until they become

large enough to rise to the top where they are automatically

released.

CAUTION: If the DISCAL

valve is not installed, commissioned and

maintained properly, according to the instructions contained in this

manual, it may not operate correctly and may endanger the user.

CAUTION: Make sure that all the connecting pipework is water tight.

CAUTION: When making the water connections, make sure that the

pipework connecting the DISCAL

is not mechanically over-stressed. Over

time this could cause breakages, with consequent water losses which, in turn,

could cause harm to property and/or people.

CAUTION: Water temperatures higher than 100°F (38°C) can be dangerous.

During the installation, commissioning and maintenance of the DISCAL

valve, take the necessary precautions to ensure that such temperatures do

not endanger people.

Installation

DISCAL

units may be used in heating or cooling systems to ensure the progressive removal of

air which is continuously formed. The units should preferably be installed after the boiler and on

the pump suction side, as these are the points where the formation of micro-bubbles is greatest.

DISCAL

air separators for horizontal pipes must be installed vertically. Flow direction of the

DISCAL

air separator is bidirectional: ﬂow in either direction is permitted. In installation conditions

where inspection is not possible, it is recommended that the venting valve cap is replaced by a

Calefﬁ Code R59681 hygroscopic safety vent. The standard replacement cap code is 59119.

CHILLER

Construction details

DISCAL

air separators are designed to allow

maintenance and cleaning without having to

remove the valve body from the pipework.

All DISCAL

air separators (except vertical

versions) come standard with a bottom

connection for installing a drain valve. All

internal air release control components are

fully accessible in all the models.

The automatic air vent, located at the top of the

units, has a long

chamber for the

movement of the

ﬂoat. This feature

prevents any

debris present in

the water from

reaching the

sealing seat. A

stainless steel

ﬂoat guide pin (3)

prevents the ﬂoat

from sticking due

to accumulating

59829

residue in the ﬂowing ﬂuids, even when the

DISCAL

air separator is not installed perfectly

vertical.

A replacement air vent assembly for the

DISCAL

brass 551 series (except vertical

and compact) is code 59829; for the DISCAL

steel 551 and NA551 series is code 59756.

The moving parts that control air venting are

accessed simply by removing the upper cover

(4). Replacement cap and ﬂoat assembly for all

versions of the brass DISCAL

551 and NA551

series is code F39807.

When cleaning, simply

unscrew the portion of the

body containing the automatic

air vent (5). For the vertical

and compact models without

a drain, the element can be

removed by removing the

upper cover(4). There is no

need to remove the air vent

body for these models.
