Witt BDP2 Instruction Manual

Please read this manual carefully before installing, commissioning or operating the BDP2
ATEX
The BDP2 without optional level sensor has no ignition sources and therefore it does not meet the definition of
devices according to the ATEX Directive 94/9 / EC. The basis for this is an risk assessment of ignition sources
according EN 13463-1, chapter 5.2. Even during possible occurring malfunctions there are no own potential igni-
tion sources present.

Instruction Manual
BDP2
Intended use
The automatic oil return system BDP2 is solely intended to return refrigerant oil
in a refrigeration or heat pump system.
Safety requirements
Any work with refrigeration systems must be carried out by trained and knowl-
edgeable personnel. All safety regulations / EC-Material Safety Data Sheets and
codes of practice concerning the use of refrigerants must be adhered to.
Under no circumstances are the indicated temperature- and pressure-limitations
on the data plate to be exceeded!
From Rev. i of 07.01.2019, the 25 bar version of the BDP is safety approved up
to 120° C. However, a continuous operation at temperatures above 75° C consid-
erably decreases the lifetime of the Teflon materials used in the BDP. During
normal operation, these temperatures should not occur (see chapter 11).
Applicable standards and regulations for installing or operating refrigeration
plants, e.g., EN 378 must be adhered to.
Before work is carried out and screws are loosened, it
is important pressure has been entirely released from the BDP2
housing.
When opening the BDP2 a sudden evaporating of trapped refrigerant
may occur. Therefore, special attention must be paid to wearing pro-
tection clothing and safety glasses.
