The installer must:
Provide a 120V 50/60Hz single-phase circuit equipped with a 20 Amp circuit breaker. Locate an outlet in close
proximity to the intended location of the Thrii unit. The Thrii unit is equipped with a 6.5 feet long electrical cord.
A GFCI equipped circuit is recommended, and likely required by your applicable regulations. If so, ensure that a
GFCI is present on the circuit that meets your locally applicable electrical/building/plumbing codes.
The circuit must be equipped with a circuit breaker that is accessible without requiring the fascia of the Thrii unit to
be opened first. Be sure to turn off the circuit breaker before working on or installing the Thrii unit.
Provide a cold water supply mounted behind the wall below the ‘hinge’ side of the aperture. Terminate the cold
water supply with a suitable isolating tap. For optimum operation a dynamic water flow pressure of between 14.5
psi and 43.5 psi is required.
If you are planning on connecting your Thrii unit(s) to a gravity-fed water supply, please contact Intersan in advance
for advice and guidance.
Provide a waste pipe with a 1-1/4” or a 1-1/2” connection and suitable deep seal waste trap behind the wall,
below the ‘hinge’ side of the aperture.

Remove the support frame from the packing box.
2.
Orientate the frame with hinge plates on the right-hand side and waste outlet parts at bottom and facing away
from you. The frame front edge should now be facing towards you.
3.
Place the frame into the front of the aperture, ensuring it is flush fitting with the finished face of the wall, at the
correct height and perfectly level in the horizontal and vertical planes. The hinge-side of the frame should be hard
up against the aperture.
