How to Upgrade Conventional R.O. System*

Connect the Pump Bot as shown.

Important: if your R.O. machine includes 4-way shut off valve (control valve), flow restrictor, manual flush valve remove them on the R.O. system itself. The unit’s internal components will be used to provide the same or enhanced functionality.

After the installation use your R.O. system as you normally would. If your tank is not full the unit will turn on automatically and fill it up with filtered water. Then it will flush the membrane and shut off automatically. If you open the faucet and take some filtered water from the tank the pump will turn on automatically to refill the tank again.

* See the product manual for further details, safety information, operating requirements and possible limitations.

With X855 model you may even turn your old system into a modern direct flow high-production R.O. machine with unbeaten water freshness, efficiency and further cost savings.

Connect the Pump Bot as shown.

Please note: you need a high-production membrane for the direct flow scheme to work acceptably. Minimum recommended production rating of the R.O. membrane is 300gpd.

Important: if your R.O. machine includes 4-way shut off valve (control valve), flow restrictor, manual flush valve remove them on the R.O. system itself. The unit’s internal components will be used to provide the same or enhanced functionality.

After the installation use your R.O. unit as you normally would. To get pure water, just open the filtered water faucet. The pump will turn on automatically and will produce the filtered water flow in real time until you close the faucet. At the end of each water production cycle the membrane will be flushed, and then the system will shut off automatically.

• Supply water pH range: 4.0-11.0
• Supply water turbidity: <1 NTU
• Supply water components: Hardness (CaCO₃) <180 mg/L (<10.5 gpg), Iron <0.1 mg/L, Manganese <0.05 mg/L, Hydrogen Sulfide 0.00 mg/L
• Maximum supply water TDS: 1000 ppm
• Electrical input: AC 100-240V 50/60 Hz
• Electrical plug: US Type A / Europlug CEE 7/16
• Maximum length of the line between the unit and the membrane (“split installation”): 50 ft (15 m) (purchase of extra tubing may be required)
• Tubing: ¼”

Weight and Size:

• Size (WDH), body only, excluding protrusions: 8.74 x 4.80 x 12.44” (222 x 122 x 316 mm)
• Weight, without water and tubing:
  • 8.2 lbs (3.7 kg) for X845;
  • 8.6 lbs (3.9 kg) for X855

Performance Guidelines:

Performance of the appliance such as pressure boost or flow rate of the connected R.O. unit is highly dependent on local conditions (inlet water pressure, temperature and TDS, R.O. membrane type and flow rating, R.O. unit type and its design specifics) and R.O. system use pattern.

• Typical pressure boost (ΔP, extra pressure built upon the inlet pressure) is up to 50 psi (0.34 MPa) for 50-100 GPD R.O. membrane for X845, and up to 100 psi (0.69 MPa) for 150-500 GPD membrane for X855. For example, the higher the GPD rate of the membrane attached or the higher the water temperature the lower is an actual pressure boost for a given setup but the higher the output flow rate in working mode. Typically, in working mode outlet water pressure reaches 80-110 psi for X845 and 110-160 psi for X855 depending on local conditions and membrane used.
• Drain water flow restrictor: 300 cc (ml/min) nominal, up to 450 cc in working mode, open flow in flush mode.
• Auto-flush duration: 18±5% s
• Idling protection: 120 minutes (the unit will shut-off the pump and goes into ‘reset required’ mode if working mode continuous duration reaches 2 hours without interruption)
