### Flow of water:
|
|
1. Filter 1 - Sediment filter
|
|
2. Filter 2 - GAC Filter (Granulated Activated Carbon Filter)
|
|
3. Filter 3 - CTO Filter (Clorine, Taste and Odour Control)
|
|
4. Low pressure switch
|
|
5. Solenoid
|
|
6. Input for TDS Adjuster
|
|
7. Membrane -> Flow restrictor on the drain
|
|
8. Merge back TDS Adjuster
|
|
9. T-Connector which goes to the Pressure Tank
|
|
10. High pressure switch to turn off the RO When the tank is full.
|
|
11. Post Carbon Filter
|
|
12. UV Filter
|
|
13. Output at 30-40 PSI as set in the Pressure Tank
|
|
|
|
TDS Adjuster will make sure that we have TDS in range that we want. It can be adjusted according to our need.
|
|
Chandigarh is making nice hard ice. We should check the TDS there and make sure that the water we use has the same TDS.
|
|
150 GPD Membrane (AXEON Maybe) Check initial TDS
|
|
[AXEON HIGH REJECTION (HR) 150 GPD MEMBRANE + LEFOO 100 GPD @ 3000+ TDS LIVE TEST](https://www.youtube.com/watch?v=-kc6B9lx7M4)
|
|
1600 mlm flow restrictor (restrictor mlm * .38 / 4 = Membrane GPD)
|
|
Check A Solenoid valve before the membrane
|
|
150 GPD pump
|
|
Check all the filters
|
|
UV Filter
|
|
TDS Adjuster to control the TDS (Input from before the membrane and output to after the membrane but before the uv filter)
|
|

Pressure tank after (35L should be fine)

line after uv tank T to ro and outlet and a high pressure switch there to turn off the ro when the pressure is high. then a T ... one to the ice machine and other to the water tank
|
|
|
|
this will take care of the RO for both
|
|
|
|
Pressure should be around 45 psi (The Ice machine requires 14-70 psi Scotsman 606) .... but with the pump, that should not be an issue

300GPD will give 40 Ltrs / hr and is also a good idea for upgrade to the basement RO. Only the Pump and RO needs to be upgraded
|
|

|
**Clean and sanitize Ice Machine every 4 months**

### Electrical Connections
|
|
|
|
1. Mains into the SMPS
|
|
2. Pump and Solenoid together into the SMPS out
|
|
3. Low Pressure (LP) switch between the SMPS out Live (Red) and the Pump/solenoid to cut out pump in case of no input water
|
|
4. High Pressure (HP) switch between the LP coutout and the Pump/solenoid to stop the pump once the output tank is pressurized |
