B. Required Connections
1. Water:
All ASTRA machines (except the Gourmet series and Steamers) are
provided with a 1/4” male flare connection in the front, under the
drain tray (See Figure 1). The Gourmet series and Steamers are
provided with the 1/4” male flare connection underneath the
machine towards the right rear (See Figure 2).
A WATER PRESSURE REGULATOR IS SUGGESTED IF THE
WATER PRESSURE EXCEEDS 50 PSI.
2. Power:
All ASTRA machines must be connected according to the local and
national electrical and plumbing codes. For a 110 - Volt machine, a
separate circuit with ground is required. A 220-Volt machine must
be connected to a single phase power (2 hot and ground ) and the
equipment must be grounded.
3. Drain:
All ASTRA machines are provided with a flexible hose (1” outside
diameter) which must be connected to the drain basket under the
front drain tray (please see Figure 1) and must be sloped properly.
Please note that all ASTRA equipment must be installed in
accordance with all applicable Federal, State and/or local
electrical and plumbing codes.
C. Water Softener
It is highly recommended that the machine be used in conjunction
with a water softener in order to ensure the integrity of your
espresso drinks and to prolong the life of the individual
components of the machine.
The water softener must be periodically serviced (regenerated or
replaced) based on your usage. Please see the drawing (Page 24)
at the end of this manual for instructions for regeneration.
