On models 2450 & 1750, screw on legs.

Connect drain hose to drain fitting located at bottom, on
front of machine.

Place flexible drain hose into a permanent drain. Make sure
there are no obstructions or kinks.

Install water filter supplied with unit. Failure to use in-line
water filter voids warranty.

Turn water “ON” and allow at least one gallon of water to
flow through the tubing on the outlet side of the filter. This
will flush out any foreign matter that may be present. When
water runs clear shut water “OFF.”

Connect copper tubing from filter to the flare inlet valve
located underneath the machine.

Turn main water supply valve “ON.” Check for leaks at
fittings and connection points.

Fully open machine valve on' " flare inlet by turning counter-
clockwise.

Flush heat exchanger by pulling the hot water handle down
and running water through the hot water spout. (Dispense
approximately 

1

/

2

-1 gallon of water.)

Check to make sure main switch is “OFF” then plug
machine into a grounded receptacle. Models 2450 & 1750
use 115V, 20 AMP receptacle. Q Models use 230V (3 wire
plus ground) 20 AMP receptacle. E models use 230V, 15
AMP receptacles with proper plug installed.

Although the main switch is “OFF” when machine is
plugged in, the red light labeled "AUTOFILL" will light up.
Water will be heard filling the boiler for three to five minutes.

When the "AUTOFILL" light is no longer on, the boiler has
filled.

Flip the main power switch to the "ON" position. (Do not turn
on until machine has completely filled.)

The vacuum breaker, located 
under the cup warming area 
on the top of the machine, 
will vent air and steam to 
the cup warning area 
upon start-up.

If the vacuum breaker 
does not close, then 
excessive steam will 
vent to the cup 
warming area. To 
correct this, 
remove the
cover from the 
machine and tap 
the top of the 
vacuum breaker.

Flush the group heads by turning both brew switches on.
Let water run for approximately one minute.

When the main power switch is placed in the "ON" position,
the amber indicator light -the heater light-will also go on.

The amber light indicates that the heating element is on,
heating water in the boiler to produce steam pressure. The
amber light will go out when steam pressure increases to
approximately 20 P.S.I.

Steam pressure decreases as steam is released to froth or
steam milk, warm cups, etc. When steam pressure
decreases to approximately 17 P.S.I., the heater light again
becomes lit, indicating that the heating element is again
heating water to increase steam pressure to approximately
20 P.S.I.

It will take 30-40 minutes for water in machine to fully heat
upon initial installation, depending on 
temperature of water source.

Cord retainers have been provided to enable power cord
and water line to be lifted off of the counter. To install, push
cord retainers into mounting holes on bottom panel as
shown. Snap cord and water line into cord retainer.
