BYPASS SETUP
Pin Valve
Pump Bypass: With the brew group in M mode, turn the associated brew
group actuator momentarily to the le. Adjust the regulator to control pre-
infuse pressure. Turn le twice in a row and adjust the pump pressure
(typically 9 bar.) Finally, turn le once more and adjust bypass pressure
using the pin valve at the pump. Adjust to taste (factory seng is 7 bar.)
The pre-infusion me and ramp up, or bypass, me
are set on the Temperature Control screen of the
display by following the direcons on page 34. Press
the buon next to the line to be adjusted and use
the up and down arrows to adjust the set me.
With these sengs in place, you can taste the eects of pressure ramping applied to each shot. The shot be-
gins with pre-infusion. Low pressure water saturates the puck, swelling it to reduce channeling. Aer the pre
-infuse me has elapsed, ramp up (bypass) begins. The bypass system creates a slow rise in water pressure
by parally diverng water away from the brew group. Aer the ramp up me ends, the bypass closes and a
brew pressure (9 bar) stage begins. Ramp down returns to bypass pressure. When in M or MP mode, the op-
erator enters ramp down by moving the group top actuator momentarily to the le. Volumetric groups can
be programmed to automacally begin ramp down at a set percentage of the shot as described on page 35.
MVP / MVP HYDRA INTRODUCTION
The MVP Hydra is a machine model with a pump and motor for each group head. The MVP Hydra has inter-
nal plumbing and wiring to accommodate separate and disnct pressures in each brew group. In contrast,
an MVP has a single pump and motor for the enre machine. Having individual pumps and motors allows
the operator to control brewing pressure at each group head, and each brew group funcons independently
without aecng the pressure at the other groups.
MVP Hydra groups can funcon in Manual mode (M) with full manual control, in Manual Program mode
(MP) with med pre-infusion and pressure ramp up, or in Volumetric Program mode (VP) with programmed
pressure ramping. Any group head can be changed on the y to any conguraon at any me.
Last Shot Brewed:
The MVP and MVP Hydra have a storage feature where the last brewing funcon is stored in a temporary
memory. This applies to any brewing funcon. If you quickly purge a screen, this will be stored as the last
shot brewed. If you manually brew an espresso that is perfect, this is the last shot brewed. The following
funcons do not change the memory of the last shot brewed:
 Turning on save mode (hold any brew group handle right for 2.5 seconds)
 Shiing thru the 6 available programs (momentary presses of the brew group handle to the right)
 Saving (momentarily pressing the brew group handle le from within save mode)
 Saving again to addional program locaons, on the same, or dierent groups
 Exing save mode (hold any brew group handle right for 2.5 seconds)
 Shiing between programs M, MP, VP, by holding the handle on the desired brew group le
When a running group is stopped, the parameters are stored. Aer shot parameters are saved they can be
viewed and altered on the hand held controller. Any alteraons are saved as new shot parameters.
