System Maintenance - Geyser ALLEGRO Manual

Replacement of cartridges of I, II, III stage
Turn the water off at the input and in the storage tank. Open the tank with clean water
to release a pressure in the system. Remove the case flask using a wrench (I, II, III stages)
and replace the corresponding cartridge. It is recommended to grease a sealing ring with
the food grade silicone or petroleum jelly before reinstallation (do not confuse with a sealing
agent!). Install the flask into position and tighten with a wrench. Check the system for the
sealness.
Before using flash the preliminary purification system. For this purpose detach the tube
from the membrane case and intercept the flow of water. Wait for the effluent water to be
clean and assemble the filter in the inverse order.

Membrane replacement
The membrane is delivered vacuum-sealed for its preservation during transportation and
storage. Before installation remove the package, shut off a tap of the tank and the water feed
tap, open the tap of clean water and detach tubes of the VI case connection (1). Withdraw the
old membrane (2). Install the new membrane and grease seals with the food grade silicone
or petroleum jelly (3). Screw the membrane case cap. Use only recommended membranes
for the replacement.
Replacement of the carbon post-filter and mineralizer
Detach tubes from the case (1), replace the post-filter with the new one, connect tubes.
Replacement of the mineralizer is carried out in the same way.
Note. Do not confuse the water input and output on the post-filter. The water flow
direction is indicated by the arrow on the post-filter case.

It is recommended to shut off the source water feed, disconnect the system from the
power supply and drain the purified water from the storage tank in case of a long (more than
1 week) interruption of the system usage.
