5. UNIT INSTALLATION 5.1 Before installation Before installation Be sure to confirm the model name and the serial number of the unit. Handling Due to relatively large dimensions and heavy weight, the unit should only be handled using lifting tools with slings. The slings can be fitted into foreseen sleeves at the base frame that are made specifically for this purpose. - Page 14 ■ To prevent exposure to wind, install the unit with its suction side facing the wall. ■ Never install the unit at a site where the suction side may be exposed directly to wind. ■ To prevent exposure to wind, install a baffle plate on the air discharge side of the unit.
