HOSE PREPARATION
It is essential the hoses are cut off as straight as possible to prevent leakage. After cutting, any
rough edges need to be removed and the cut needs to be cleaned. Bevelling the hose ends slightly
will aid the assembly. Use a sharp knife or scissor to prevent crimping of the hose. Make sure to
install all hoses in such a manner that they are not in contact or exposed to a heat source.
HOSE LENGTHS
With the components fitted and placed in their respective final locations, the hose lengths can
be determined. The hoses must be dimensioned in such a way that they can be fitted to the
individual components without sharp bends, kinks or over-stretching. Allow for over length to
move the unit when the membrane needs to be replaced. In case the hose sections supplied in the
kit are not sufficient to complete the installation as is explained in this manual, extra hose might
be required. Make sure that, when purchasing extra hose from external sources the hoses are of
the correct diameter and are genuine food quality.
Two types of connections are used in the installation.
1.
Push-in connections
With push-in connectors, the correctly prepared hose is simply pushed into the coupling.
Pushed in sufficiently, the hose will bottom on a ridge inside the coupling (Fig. 16a).
After the hose bottoms, the hose must be pulled backwards (away from the connector) to
lock the coupling. Pulling back the hose also pulls back the locking ring on the coupling,
and with the hose firmly pulled back a leak free connection has been made (Fig. 16b).
The hose can be removed from the coupling by means of pushing the locking ring in and at
the same time pulling the hose out (Fig. 16c).
It is advised to closely inspect the hose for damage after removal before using it again.
In case of doubt the damaged or suspect section must be cut off. See figures below for
push-in coupling handling.

Screw on connections
With the kit two of screw/push-in connectors are supplied to connect the system to the
water supply, and to the drain system. See figure 17 below for their appearance and
application.
