English 299.3 Level Check of the Indoor UnitAfter the indoor unit is installed, it is required to check the level of the whole unit. The unit must be placedhorizontally, but the condensate pipe shall be installed obliquely, so as to facilitate the drainage of condensate.Air SupplyBAir IntakeCondensate DrainpipeLevel InstrumentCondensate DrainpipeEnlarged ViewiAs the inside of the unit is inthe negative pressurestatus, it is required to setup a backwater elbow.

Firstly apply liquid nail on the pipes, then,attach the thermal insulation cotton with a layer of tinfoil. Use the liquid nail cover to fix it. Lastly use tinfoiladhesive tape to carefully seal the joints. Other good thermal insulation materials can also be used.The air supply pipes and the air intake pipes shall be fixed to the prefabricated boards of the ceiling by•using iron supports. The joints of the pipes must be sealed by glue so as to avoid leakage.The design and installation of air pipes must be in conformity with the relevant state engineering criteria.•The edge of the air intake pipe must be at least 150mm away from the wall. The air intake must be covered•with filter.Silencing and shock absorption shall be considered in the design and installation of the air pipes. Addition-•ally, the noise source must be far away from where people stay. The air intake shall not be located abovethe place where users stay (offices and rest places, etc.).
