Operation

2.1 Installation

The standard pump (except the versions

equipped with an explosion hazard rated

motor) is not suited for installation in explo-

sion hazard areas. Pumps equipped with

EExcIIT3 motors may only be used in type

2 areas. When planning such an application

please contact us first.

The TRIVAC-B pump can be set up on a flat, horizontal

surface. Rubber feet under the coupling housing ensure

that the pump can not slip.

If you wish firmly install the pump in place, insert bolts

through bore holes in the rubber feet.

Max. tilt for the pump (without further

attachment) with possibly fitted standard

accessories is 10° from the vertical.

The rubber feet act as vibration absorbers.

They must therefore not be compressed by

screws. When installing the TRIVAC-B

pump, make sure that the connections and

controls are readily accessible.

The site chosen should allow adequate air

circulation to cool the pump (keep front and

rear unobstructed). The ambient temperatu-

re should not exceed +40 °C (104 °F) and

not drop

below +12 °C (55 °F) (see Section 2.5.3).

The max. amount of heat given off approxi-

mately corresponds to the rated motor

power.

2.2 Connection to the

System

Before connecting the TRIVAC-B, remove the shipping

seals from the connection flanges (7/2) and (7/3).

Retain the shipping seals in case you need

to store the pump in the future.

The pump is shipped with intake and exhaust flanges

mounted for horizontal connection of the connecting

lines. You can easily convert the ports for vertical

connection by removing the four capscrews, rotating the

flanges as required, and reinstalling the capscrews.

Connect the intake and exhaust lines with a centering

ring and a clamping ring each. Use the centering ring

with dirt trap for the intake port.

Connect the intake and exhaust line using anti-vibration

bellows, without placing any strain on the pump.

The intake line must be clean. Deposits in the intake line

may outgas and adversely affect the vacuum. The

connecting flanges must be clean and undamaged.
