Page 22: Product Handling And Installation
This chapter mainly introduces the air conditioning works required to be conducted or focused after the product is arrival. The Vertiv standard AHU is delivered in two sections. The lower section should be positioned in the final operating location first. The upper section should be carefully lifted and mounted on the top following the instructions provided. Always ensure operator and equipment safety procedures are followed. - Page 23 This floor stand is also conducive to the connection of the AHU condensate drain pipe, so it is recommended that the height be above 100 mm. Figure 5-3 is a schematic diagram of the floor stand for customers’ reference. Figure 5-3 Schematic diagram of floor stand Vertiv™ | Liebert® AHU | Technical Manual...

Page 28: Maintenance Space Requirements
5.5. Maintenance Space Requirements Note1: AHU is advanced precision air conditioner and the recommended way is to install them as a standalone equipment. Note2: Do not use the indoor unit in open and harsh outdoor environment. Note3: Avoid positioning the indoor unit in concave or narrow areas, which can baffle the airflow and shorten the cooling cycle resulting in short circuiting of air and air noise. -
