0 Important Safety Information
0.1 Mechanical hazards
1 Avoid exposing any part of the human body to the vacuum.
2 Never operate the pump without a connected intake line or without fitting
a blank flange on intake port.
3 Do not operate the pump with any of the covers removed. Serious injury
may result.
4 The location at which the TRIVAC
®
T (including its accessories) is being
operated should be such that angles over 10° from the vertical are avoid-
ed. Select the operating place so that all controls are easily accessible.
5 The pump when filled with oil must only be moved in its vertical position.
Spilled oil involves the risk of falling.
6 Make sure that the gas flow from the exhaust port is not blocked or re-
stricted in any way.
7 If exhaust gases must be collected or contained, do not allow the exhaust
line to become pressurised. The pressure in the oil box must not exceed
1.5 bar (absolute). An exhaust line which is too small in diameter or which
is blocked can result in the formation of overpressures within the pump.
Possible consequences can be damage or even burst open the pump.
Thus the exhaust line must be checked from time to time to ensure that
there are no obstructions.
8 When moving the TRIVAC
®
T always use the lifting means provided.
0.2 Electrical hazards
1 The electrical connections must only be provided by a trained electrician
as specified, for example, by the regulations EN 50110-1. Observe local
regulations.
2 Lethal voltages are present at the mains connections. Before starting with
any maintenance and service work, de-energise (lockout/tagout) the prod-
uct first.
3 Lay connecting lines so that they cannot be damaged. Protect the lines
against humidity and contact with water. Avoid any heat stress on the line
due to unfavourable laying conditions.
4 Suitably support the connecting lines so that the pumps are not exposed
to any major mechanical stress.
5 After a mains power failure the pump will run up automatically again. This
also applies in the case of an emergency shutdown. In order to prevent
the pump from running up automatically again, the pump must be inte-
grated within a control arrangement such that it can only be switched on
manually again after the mains power has returned.
6 Provide an adequate wall ground connection for the pump so as to avoid
any electrostatic charging.
7 Before starting up for the first time, the motor circuit must be equipped
with a suitable protective motor switch. Please take note of the infor-
mation in these Operating Instructions and on the electric motor (wiring
diagram).
