Install the back hanger to the location shown in the diagram.

Clean the area around the urinal drainage 
outlet of dirt and water, 

then attach the 

seal ring to the urinal drainage outlet.

  

Align the centers of the urinal drainage 
outlet and drainage flange, then hang 
the urinal unit from the back hanger.

Be careful not to tighten the 
nut too strongly and crack 
the urinal unit.
Be careful that the shutoff 
valve does not strike the 
urinal unit.

Fix the flange bolt to the lower part 

of the urinal with the washer (large) 

and nut.

*  The washer (large) and nut are 

packaged with the drainage flange.

*  The hex size of the nut is 13 mm.

A board ratchet wrench with a total 

length of 150 mm or less is 

recommended to tighten the nut.

CAUTION

CAUTION

Planar view

Drill a pilot hole of around Ø3 at the 
marked installation hole position. 

*  Drilling a pilot hole of around Ø3 will 

make it easier to work.

Do not immediately fix the back hanger 
with the three wood screws; instead, 
temporarily fix it with the elliptic holes 
only.

 

Attach the seal ring onto the urinal  

 for a trial at first,

 hang the urinal from

the back hanger, adjust it to the indicated 
position, then fix it in place. If the urinal 
does not reach the indicated height, 
loosen the back hanger's wooden 
screws, then place a metal plate 
between it and the wall to adjust it.

Refer to the

 

Installation Manual

 attached to the urinal for information
 on how to install

 the quick fastener.

CAUTION

Insert the valve straight into the shutoff valve.

*  Use a switch box for a single device 

(no cover).

*  A grounding wire is not needed, so 

use a two-core power wire.

*  Use a screwless conduit (nominal 

designation, provided on-site).

*  Leaving around 40 cm of slack outside 

the box, wind the power wire inside the box.

Align the flanges on the shutoff valve and valve, 

then insert the quick fastener.

*  If the valve is not fully inserted, it will be impossible 

to install the quick fastener.
Confirm that the flange is fully inserted into the 

recess on the quick fastener, rotate it to the front and 

rear, then check the connection between the shutoff 

valve and valve.

If the quick fastener does not rotate 

smoothly after connecting it, reconnect it

If the quick fastener is not connected properly, 

water leaks could result in flooding damage to 

property, such as household belongings.

Install the quick fastener properly, then 

check visually or through other means.
