Title: Instructions manual - THGT fan.pdf
The following risks have been identified for consideration:- Installation: incorrect installation or function represents a risk to safety. Rotational speed: identified on fan name plate and motor. Never exceed this speed. Rotation of impeller: identified on fan with direction arrows. Do not run impeller in reverse. Working temperature: identified on fan nameplate and motor for S1 duty cycle. Never exceed this range. Refer IEC 60034-1. Protection devices: These should always be operational and never disconnected for S1 duty cycle. Refer IEC 60034-1. However, Emergency ventilation fan and motors are suitable for S1 duty cycle, and one off emergency smoke operation, where fan is able to run at stated temperature and time, or to destruction, and thus no motor protection devices must stop this. The fan motor power supply must be designed to accommodate any motor protection devices, where applicable, for S1 duty cycle and these must be disabled or by-passed in event of one off emergency smoke operation.
