MACHINE INSTALLATION
CONNECTING TO MAINS WATER SUPPLY – EVOLUZIONE R, R 58
and R 60V RANGES ONLY
The Rocket Espresso Evoluzione R, R 58 and R 60V ranges are built
with full commercial rotary pumps. This feature enables the user to
connect the machine directly to the mains water supply.
The Evoluzione model range is preset at the factory to use the
supplied 2.9 litre water reservoir.
The R 58 and R 60V controllers are preset to source water from the
machines water reservoir.
To connect the Evoluzione, R 58 or R 60V machine to mains water
supply, use the steel braided water hose provided and ensure the
following instructions are adhered to:
1. Use a certified plumber to complete the installation and ensure
that the installation meets local authority standards and
regulations in all cases.
2. Line pressures exceeding 5 bars should be limited with the use of
a pressure-regulating valve on the water feed line.
3. Use a shut off valve to isolate the water supply to the machine.
4. If you are drawing water from a non-pressurised system (ie. from
a remote water supply tank, not mains pressurised) fit a non-
return valve to the end of the water supply hose to ensure that
the line pressure is maintained at all times.
5. Use an inline filter to ensure the water supply to the machine is of
the highest quality (example: Everpure OCS filter range).

complete it will be necessary to
switch the machine from water tank
supply to mains pressure supply.

6. For the Evoluzione refer to Fig A. Remove the water reservoir
tank from the machine, move the switch from the water tank icon
position to the water tap icon position. In the case of the R 58 or
R 60V please see ‘Programming your R 58 / R 60V’.
7. Mains water supply will result in a different line pressure to
the machine. It will therefore be necessary to adjust the pump
pressure for optimum extraction results. Fit the blind filter into
the portafilter and insert the portafilter tightly to the group head.
8. Open the group lever (as if to make coffee) and take note of the
maximum pump pressure reading (pump pressure is the right
hand gauge). Pump pressure should be at 9 bar. Close the group
lever to release pressure.
9. Should the pump pressure require adjusting, it is externally
adjustable from under the machine (Fig B). With care using a
14mm socket loosen the pump pressure adjustment lock ring.
10. Using a short screwdriver to adjust the pump pressure. With the
pump running, turn the screw (brass colour) whilst observing
the pump pressure until the required 9 bar pressure is achieved.
Turning anti clockwise will decrease the pressure, clockwise will
increase the pressure.
11. Re-tighten the lock ring.
12. The procedure is now complete. Follow the rest of the installation
guidelines on the next page except for step 2 (filling the water
reservoir).
