The Lead-in is connected to the plastic so that the rabbet of the sealing is on both sides of the barrel
plastic and tightened securely.
A hose connector is screwed onto the internal thread, which is left outside
the inlet barrel. The removal and its hose connector are used as a bottom
coupling, which fits directly to the delivered hose. The supplied shorter
plug must be replaced into the removal, so that it can block the side hole.
(Picture on the right) Keep the longer plug, so that you can close the Lead-
in again completely. The removals of older barrels have a valve and a hose
connector, where the hose can also be connected, so then the plug is not
needed.
In all the threaded joints, where there is no sealing, approximately 12-18 windings of pipe tape should
be used, to ensure that the joint is definitely sealed.
The hose should be cut into pieces of suitable length, either in two or three parts. The third part can
be used as a filter to remove dirty water, when connected to the sand filter. These hose connectors
come with tube clamps.
Instructions regarding coupling the hoses between the filter and the pool, can be found in connection
to the filter. On the left, you can see the basic principle of hose coupling.
Before you connect the actual filter or use it. You shall
install the protection grids on all the lead in parts in the
hot tub. One on the bottom, one on the heater return pipe
and the last one to the newly installed part on the wall.
The grids prevent bigger particles, hair etc. to enter the
piping and this prevents damage and accidents while
using the filter pump.
Updated 13.9.2017
For winter and other times when the filter is removed, the return
opening must be plugged with the cover/plugs included in the
delivery. When the hot tub is not being used, the lead-through
plug should be completely removed so that it doesn't get stuck on
the lead-through part. During cold weather, the hot tub's valves
(in older hot tub models) should be left half open even if the hot
tub is empty, so that any water collected in the valves doesn't
damage the valves when it freezes.
