Installation
The method of installation of rainwater outlets depends on the gutter material. Gutter thickness should be at least 1.5 – 2 millimeters.
For Stainless steel gutter, installed by Argon-welding method
															- Mark the position of rainwater outlet
 
															- Drill a 220 mm. hole
 
															Wipe the gutter clean
															Place Spigot assembled with Adapter Flange on the hole
															Weld Spigot all the way around to secure the position
															Slit the rubber gasket off
															Install Stud Rod and Spacer at all 4 points
															Install Anti-Vortex Plate and tighten the nut at all 4 points
															Installation complete
For steel gutter, installed by bolt and nut tightening method
															- Mark the position of rainwater outlet
 
															- Drill a 220 mm. hole
Wipe the gutter clean
 
															Mark the position by the holes on Backing Ring onto Spigot to all 10 points
															Drill holes on Spigot as marked for all 10 points
															Place Spigot on the gutter, then mark the position on it, and drill all 10 holes
															Caulk silicone sealant on the gutter, then place a rubber gasket and caulk it with silicone sealant again
															Place Spigot onto the rubber gasket, then install all 10 pieces of Bolt M6.
															For underneath the gutter, install backing Ring, then tighten all 10 pieces of Nut M6
															Install the rubber gasket
															Install Adapter Flange followed by Backing Ring, then tighten Nut M6
															Install Stud Rod and Spacer for all 4 points (place Spacer higher from the Spigot base at least 3 cm.)
															Install Anti-vortex
															Tighten Nut M8 over all 4 points
															Installation complete
For concrete roof, installed by concrete embedment method
															Drill a hole at Spigot’s wing for the threat of Stud Rod to secure the outlet’s position
															Drill a hole on shutter board to position the Sleeve
															Place concrete outlet covered with plywood to prevent mortar fill-in, which can cause clogged downpipes
															Set the outlet level with the top edge at the same height as Depressed Floor
															Tie the wire to secure the outlet’s position
															Use a horizontal level indicator (water level gauge ruler) to check the gradient and weld to secure position
															Concrete pouring and casting.
															When the concrete is set and the rainwater drainage pipework is ready to use, remove the plywood
															Slit the gasket out
															Install Stud Rod M8 and Spacer
															Install Anti-Vortex and tighten Nut M8
															Installation complete
JAS Siphonic Rainwater Pipe Installation
The installation of JAS Siphonic system pipe must be installed in accordance with ISOMETRIC Drawing created by design engineers. The ISOMETRIC drawing will indicate the pipe size and pipe length based on the actual work site. In case that the actual pipe length from site work has changed or the pipework cannot be straightened according to the ISOMETRIC Drawing, the design team will re-calculate the change in pipe size and pipe length to be precisely installed in order to make the siphonic rainwater drainage function at full capacity.
An example of ISOMETRIC drawing for JAS Siphonic system pipe installation
Type: Multi-Outlets system 
Pipe: HDPE 
Method: Butt Fusion

Overflow Channel Installation
at the gutter can reduce the risk of overflowing rainwater to the building due to heavier-than-usual rainfalls or clogged downpipes. The overflow channel must be installed to enhance the building’s safety,
