Air Conditioner Pipe Pre-Installation

Before or during renovation, the air-conditioning technician plans the connections between the indoor and outdoor units: the interconnecting cable, refrigerant pipes, drain line, and power cable. This allows the units to be placed in less conventional locations and helps avoid disruptive drilling and wall-chasing after renovation, which can create considerable dust and inconvenience.

Pre-installation steps

1. 01Assessing the site and agreeing on indoor and outdoor unit locations, with room for future maintenance
2. 02Planning the refrigerant pipe route and required diameter, as well as wall penetrations between the units
3. 03Installing and insulating the refrigerant pipes in advance, then protecting their ends from construction dust and debris
4. 04Planning the condensate drain route and providing the required slope for unobstructed water flow
5. 05Routing the interconnecting and power cables; sizing the power cable for the equipment and electrical load
6. 06Checking the connection routes before wall finishing, and verifying drainage operation and refrigerant pipe tightness
