• the electrical connection must have separating device built into the permanently installed
electrical installation, which enables the disconnection of all electrical contacts with a
contact space of min. 3 mm from the mains. Pay attention that the supply voltage is
correctly protected and an earth-leakage circuit breaker ≤ 30 mA is installed.
• Only use the equipment in dry rooms, in which no combustible gasses and vapors are
present.
• Do not put the equipment into operation immediately if it has been taken from a cold to a
warm area. The thereby developing condensation water could destroy your equipment
• If the equipment has visible damages, does not work anymore or has been stored under
adverse conditions for longer periods, then it is to be expected that a safe operation is no
more possible. In this case the equipment is to be secured against unintentional start-up
and if necessary to be decommissioned.
• Live parts can be uncovered when opening the cover or removing parts. Before an
alignment, maintenance, a repair or change of parts or devices, the equipment must be
separated from all voltage supplies, if opening the equipment is necessary. If after that an
alignment, maintenance or a repair on the opened equipment under voltage is inevitable, it
may only be done by experienced, skilled staff, which has knowledge of the associated
dangers and/or the relevant regulations.
• Capacitors in the equipment can still be charged, even if the equipment is separated from
all voltage supplies.
• Assembly and/or disassembly of the valve only in a pressure-free status (i.e. empty piping
beforehand)
• Valve flow and/or direction of flow must be considered.
Each person involved in the operation and maintenance of the equipment
must have read and understood the present operation manual!
It is for your own safety!
