Possible Application; Operation - HEYLO PV 4200 EX Bedienungsanleitung

(2) Possible application

In potentially explosive environments, transport ventilator PowerVent 4200 EX is the right choice. It
draws off dangerous gases safely and quickly. The housing made of a robust ABS carbon plastic
passes voltage into the floor and thus prevents static charges and for this reason dangerous sparking.
The housing and motor sealing is in keeping with the high protection class IP65 and offers an effective
protection against dust and water.

(3) Operation

Before starting up the ventilator, set the unit to the correct voltage. (230 V is preset)
Connect the unit to an earthed socket and set to switch A to ON. Check correct operation before
leaving the unit unattended. Do not move or carry the air mover during operation. Observe the
direction of air. It is marked by an arrow B on the housing.
