WARNING! DO NOT LOOSEN THE CONNECTORS FROM THE ENCAL 3000
HOUSING. THE SOLDERED TUBE WILL BE DAMAGED! THE JOINT BETWEEN
CONNECTOR AND HOUSING IS AN INTEGRAL PART OF THE ENCAL 3000's
ATTENTION
SAFETY APPROVAL
To prevent loosening the connectors use a second key wrench to prevent the coupling
from turning.
IF THE CONNECTOR IS ACCIDENTALLY LOOSENED PLEASE SWITCH OF THE
ENCAL 3000 AND CONTACT THE MANUFACTURER
CAUTION
The adapter can be replaced without removing the hood from the gas chromatograph
and is suitable for connecting a Swagelok pipe fitting (3 mm or 1/8").
Each gas outlet consists of the coupling (a 1/8" Swagelok pipe fitting) and a filterless
adapter. The adapter can be replaced without removing the hood from the gas
chromatograph and is suitable for connecting a Swagelok pipe fitting (3 mm or 1/8").
The external pipework required should be made of stainless steel and permanently
connected. The supplied sample gases must comply with the specifications or be pre-
filtered as the particulate filters in the adapters are only designed to protect the device
The breather valve (also known as a vent valve or short breater) on the rear of the housing
is used to allow an atmospheric pressure equalization process between the interior of
the device and the ambient area so as to comply with the ATEX regulations.
These state that the gauge pressure inside the housing must not exceed 100 mbar in
the event of a complete gas rupture, in other words, if all the gas supply lines inside the
housing were to be detached at the same time.
DO NOT UNSCREW THE BREATHER VALVE.
DO NOT CONNECT THE BREATHER VALVE'S PIPELINE TO OTHER PIPELINES.
CAUTION
The breather valve in the device is made from Stainless steel and sintered metal. It is
suitable for a IIC and for Class I/Division 1 environment in conjunction with capillary
flame arrestors with an ID of maximum 0.015" (0.38mm) and a length of minimal
250mm. It has an outlet connection of ¼" NPT
It must not be sealed or blocked, for example by water, condensation, ice, insects, dirt or
the like, as otherwise the pressure equalization process will be adversely affected. In the
case of outdoor installation, it may be protected, for example by connecting a gooseneck
pipe or a vent line.
