INSTALLATION PROCEDUCE
1. Please select an appropriate branching pipe set model and a pipe size by consulting with the installation manual of the indoor unit
or other relevant technical documents.
Attention
①
Use a pipe conforming to a pipe size specified for indoor unit connection for the section between an indoor unit and a branching pipe.
②
Use a pipe conforming to a pipe size specified for outdoor unit connection for the section between an outdoor branching pipe and an outdoor unit.
2. Cut a branching pipe set or a different diameter joint with a pipe cutter to make it fit for a selected pipe size before application.
Attention
①
In cutting pipes, always use a pipe cutter. Remove burrs from a cut end when you cut a pipe. In doing so, keep a cut end downward so
that no chips or burrs may enter the pipe.
②
Take utmost care so that no foreign matter such as dust or water may enter piping during installation work.
・
Please cover all the open ends of piping until installation work is completed. Particularly, any openings in the section of piping laid
outdoors should be sealed stringently.
・
As long as possible, avoid open ends left facing upward. Make them face either horizontally or downward.
③
A branching joint (for both gas and liquid) must always be positioned in such a way that it branches either horizontally or vertically.
・
In the case of a branching pipe set (model type DIS)
・
In the case of a outdoor unit’s branching pipe set (model type DOS)
