Installation and Use: 1) can be vertical, horizontal and hanger installation. Fan base must naturally be combined with basal plane, and not to beat coupling force base, the weight of the pipe shall be applied to the turbine components. 2) should be carefully checked before installing the impeller and the casing has no transportation damage and deformation htf fire exhaust fan, exhaust fan, if any, should be repaired before installation. 3) Check the connecting bolt is loose, the motor insulation is good two-speed exhaust fan fire price, whether or hinder the rotation of objects within the fan duct. 4) To install the fan after commissioning, abnormal rub, touch, and vibration to be excluded immediately. Two-speed exhaust fan to be more and more applications in high-level basement, garage ventilation exhaust power, then we must pay attention when installing wiring normative approach, the size of the compiled it for you today talking about the two-speed fan Wiring Methods: Large two-speed exhaust fan wiring methods: In general, the distribution of electrical power in the following 4KW Y junction; 4KW above (including 4KW) △ connection. Large air-conditioned two-speed fan of the group of companies with dual-speed motor stator winding is △ / YY (or Y / YY) connection. Two-speed exhaust fan control principle: The Company of the two-speed fan motor with double quick set its stator windings △ / YY (or Y / YY) connection, the basic principles of the connection method of vertical speed motor stator windings by changing fire exhaust fan to change the number of poles in order to achieve the purpose of speed, low-speed work for △ (or Y) method; YY way for high-speed work. The electrical control box with wind breakers, protective devices and other electrical components must be correct and reasonable by matching fan rated capacity.
