Installation Guidelines

Pipe Preparation

Step	Action
1	Cut pipe square using pipe cutter or sharp blade
2	Deburr pipe end to remove any rough edges
3	Ensure pipe end is clean and free of debris
4	Mark insertion depth on pipe for verification

Installation Procedure

Inspect tee for debris or damage before installation

Loosen mechanical joint clamps on all three ports

Insert first pipe end until it bottoms out (check depth mark)

Tighten first clamp to specified torque (5–8 Nm typical)

Route second pipe and insert into opposite end

Tighten second clamp and verify alignment

Insert branch pipe into third port

Tighten third clamp and verify all connections

Pressurize system and check for leaks at all three connections
