Multiple reducers/ crimped duct Serve bends Multiple direction changes 3.5 Exessive use of flex-duct and long flex-duct runs should be avoided. 3.6 Fire dampers must be fitted as per national and local fire regulations.
  • Page 10: 4、Installation Method

    Installation Method 4 Installation method 4.1 Preparing the anchor bolts Mount the washers (outer diameter of>21 mm for M10, >24mm for M12) and nuts onto the pre-recessed anchor bolts (M10 or M12), as shown in the figure below. When using (customer-prepared) vibration isolation rubber, there is a possibility of this causing a decrease in strength, so we recommend the following type of construction.

  • Page 20 Precautions for Use 11. Intelligent air volume compensation (PS: only applicable to the highest speed): During the long-term operation of the equipment, the filter screen will accumulate dust and gradu- ally block, which will lead to the increase of equipment resistance and the decrease of air volume. In order to make up for the air volume loss, the air volume will be increased along with the regular pres- surization of the supply and exhaust fans (the pressurization percentage can be set in the parameter item).
  • Page 21 Precautions for Use 16. One button high speed Application: In the kitchen or bathroom, the equipment can be turned on remotely through the rocker switch. One remote rocker switch control interface is reserved on the mainboard. When the interface is connected, the supply fan and exhaust fan operate under the highest speed.
