Fitting and Wiring Instructions
SAFETY INSTRUCTIONS FOR AIR MOVEMENT EQUIPMENT
Air moving equipment may present mechanical, electrical or noise hazards. To minimise risks associated with these potential
hazards, it is essential that safety, installation, operation and maintenance instructions are followed.
Implementation of these instructions should always be undertaken by technically competent personnel.
Potential mechanical hazards must be eliminated by guarding against access to the rotating parts whilst the air moving
equipment is operating. A range of guards are available for this purpose from Vent-Axia.
Installation work, both mechanical and electrical, must be undertaken in accordance with the safety and installation
instructions before switching on the unit.
Maintenance work should not be attempted before first switching off and isolating the fan and its control from the electrical
supply and ensuring that it cannot be accidentally turned back on again. It is essential to ensure that rotating parts have come
completely to rest before maintenance work commences.
Air moving equipment may generate unacceptable noise levels when in operation. Actual sound levels are indicated in the Vent-
Axia Industrial catalogue for each product and it may be necessary to take appropriate action to reduce sound levels.
A range of products are available for this purpose from Vent-Axia.
