Requirements To The Source Water - Geyser ALLEGRO Manual

ATTENTION! The reverse osmosis system performance directly depends on a pressure in a
water conduit. If a pressure in your water conduit is less than 3 atm., that it is necessary to
complement the reverse osmosis system with the booster pump.
The water pressure at the inlet of the system with a pump, atm.
The water pressure at the inlet of the system without a pump, atm. 3-8

Higher values of indicators require the additional preliminary purification.
ATTENTION! If characteristics of the source water do not comply with the specified
requirements, that the operating life of the membrane and replaceable filtering modules can
be smaller than the operating life stated in this manual.
RECOMMENDATIONS FOR CONNECTION AND OPERATION
the connection is carried out only by the qualified specialist or the manufacturer's
„
representative;
strictly follow the manual in case of individual connection;
„
all filter cases were tested for sealness and hydraulic impact, that is why there is on
„
water inside cases of the filter;
it is not recommended to disassemble factory connections without the need.
„
PREPARATION TO THE CONNECTION
1. Shut off the cold water feed to the connection point
(Fig. 1) and discharge a pressure by opening the mixer.
2. Make sure that the filter flasks are reliably tightened * .
Tighten them, if necessary.
* Periodically check a reliability of the filter flasks tightness and
tighten them, if necessary.
Attention! A position of the vertical label, which is placed strictly
align the filter front center, does not guarantee the connection
leakproofness. A position of the label can be changed during
tightening of the flask screwed connection.
