Installation for Premium Norma/Optima tubs
Kirami aluminium tubs have Ø75mm connection pipes and
connection plates. The heater is fixed to the tub with two rubber
hoses and two plates on the sides. (Picture on the right)
1) In the DIY versions of the tubs the plates are installed for
correct width by inserting the plates into the holder from
the outside. In the panelled tubs the plates are
preinstalled.
2) The heater is pushed into its place so that the tub pipes go inside the hoses on the heater.
And the heater remains in horizontal position.
3) Tighten the hose clamps form both ends.
4) Use the supplier self-drilling screws to fix the heater to the tub's plates. The screws are
meant to drill through the wooden panel, the tub plates
and the heater plates. There should be three screws on
each side of the heater. Four top ones make the actual
fixing and the two lower ones fix the panel so that it stays
in nice vertical position. If a drink holder / panels is not
installed the only two screws are used on both sides.
The heater will be hanging on the wall of the tub by the hoses and
plates. Some support can be added underneath the heater if
necessary.
