Reverse Osmosis System
Model – 021-4P-GM
Congratulations on your purchase of the
most advanced water purifier system
available!
Installation and Service Guide short web version,
this is not the instruction manual you will receive
with your purchase of a PSI-021-4P-GM but a
shortened version that is available on our web site,
it is a shorter version due to other suppliers likely to
copy this instruction manual as their own.
This reverse osmosis system is designed for those persons that want to self maintain the system and
using the extra equipment supplied with this unit analyse how the system is operating.
The gauges measure the mains water pressure (bottom Gauge), the top gauge measures the pressure
after the water has passed through the two primary cartridges. The sediment from the mains builds
up on the cartridges and will start to slow the flow rate through the primary cartridges, this pressure
drops the pressure and this is shown on the top gauge, by noting the pressure difference between the
two gauges indicates the level of pressure drop.
The total dissolved solids (TDS) meter supplied with the unit measures the success level of the
membrane in parts per million TDS, this is an electronic devise and is simple to use, you fill a clean
glass with tap water and take a reading, then fill the glass with reverse osmosis water and take a
reading, the difference between the two readings gives you the success rate. The reverse osmosis
systems are very reliable, the TDS meter is really to re-assure all is working well.
