If not there may be water leakage from the indoor unit when the air conditioner is operating in cooling mode. It is possible to realize the pipe connection on Baxi Astra Indoor Unit by simply removing the below cover panel in the inferior part of the unit... - Page 18 Installing the connections between the two units Drill a hole 70 mm in diameter on the left side (rear view) or right side (front view) with a slight downward slope. Use adhesive tape to hold the indoor unit fitting in place. Then wrap the connection with electrical tape to prevent condensation.
- Page 19 Installation with side connections lt is also possible to install the indoor units using the existing side pre-shearing. Please note that the wiring, the drainage, and the refrigerant connections are fully suited for connection on either side of the unit. Even when installing with feedthrough connections, wrap up all the connections to prevent condensation problems.
