1. Dispose of packaging properly
2. Un-coil power and water supply
3. Connect 1/2" threaded pipe connecon
to water supply (Fig. 1)
4. Install drain hose, route hose up through access hole
under unit and push onto barb fing on the side of
the drain pan cup (Fig. 2)
5. Connect other end of the drain hose
to drainage system
6. Check incoming water pressure
• Incoming water pressure cannot exceed 20 bar
or 290 psi as this will damage the pump and
internal components
• Maximum incoming water temperature cannot
exceed 158°F as this will damage the
pump and internal components
• If incoming water pressure is less than 1 bar or
15 psi, the unit will me out and must be turned
off; This will cause excessive wear and tear on
the pump and void the warranty
• User must install pressure booster for incoming
water if below 1 bar or 15 psi

INITIAL SETUP

5
1. Turn unit on (Fig. 3) and allow boiler to fill;
internal pump will shut offwhen full
(2-3 minute fill me)
Dispensing buons will flash sequenally
during startup, leto right
2. Watch the water level site gauge (Fig. 4)
(Green secon = good)
3. Unit will start heang and building pressure once
site gauge ball is in the green
NOTE: If green level is not reached, refer to
troubleshoong on page 11
4. Boiler pressure gauge = 1.2 bars before use (Fig. 5)
NOTE: Could take up to 30 minutes depending
on unit size; If pressure does not build, refer to
troubleshoong on page 11
1. Flip program switch up to the "ON" posion (Fig. 6)
NOTE: Right most group head buons are default
for other group(s), but can sll be changed if needed
2. Dispensing buons will light up solid blue in color
3. Press program buon so just cup size lights are on
(Fig. 7)
4. Press and hold cup size(s) buon unl desired output
is reached for each size; Program 1 cup size at a me
5. Press program buon to secure cup size
programming, this will then move to the next cup
size or press again when finished with programming
6. Flip program switch to the "OFF" posion (Fig. 6) to
return machine to operang mode

portafilter
3. Press buon 1 and 5 simultaneously to start
flushing (Fig. 8)
4. Buons 2 and 4 will light up (Fig. 9); automac
reverse flushing will start and run for 10
cleaning cycles
5. To stop the reverse flushing before 10 cycles,
press buon 3 (Fig. 10)
6. Each group head should be cleaned this way
7. Turn power switch off(Fig. 11)
8. Turn offwater supply to machine
9. Turn all steam wand knobs to open
and leave them open to release
pressure from inside boiler tank
(Fig. 12)
10.Remove drain pan and grate
11.Open drain valve (Fig. 13), red lever
should be parallel with drain line,
leave drain valve open to completely
empty the tank
12.Wipe down machine as needed to

tank is empty
2. Disconnect from power supply
3. Remove 2 screws from top rear cover and
remove cover (Fig. 14)
4. Remove pressure relief valve from top of
boiler tank with 19mm wrench (Fig. 15)
5. Add water and descaling mixture to boiler
tank via pressure relief valve port unl site
gauge is in the upper half of the green secon
(Fig. 16)
6. Allow unit to soak as required by descaling
product
7. Drain and flush boiler tank with fresh water
8. Reinstall pressure relief valve and top cover
9. Cycle each group head to ensure all descaling
product is removed before use
