Connecting to a Water Supply
All Espresso Café machines must be installed with an Everpure water filtration
system. This system consists of a QL3 filter head (with shut-off valve) and 4H
water filter cartridge. This system is compatible with the Everpure Model JT
Sanitizing Cartridge, which is required to perform the In-Place Cleaning
(sanitizing) Cycle in compliance with NSF standards.
NOTE: The w ater filter must be installed between thewater source and the
coffee maker (maximum 3 feet away). Also note that the inlet valve is
equippedw ith aflow regulator andbackflow preventionsystem.

12
Connecting to a Water Supply
1. Connect a ¾” inlet fitting to the inlet valve at the rear ofthe coffee maker,
making certain the rubberwasher is inserted between the fitting and the
inlet valve.
2. Tighten the fitting onto the inlet valve – hand-tighten only. Connect the
water tubing to the fitting and install the lock clip to lock it in place.
3. Turn the wateron at the source,checkfor leaks and repair, if necessary.
4. Plug the service cord into a walloutlet and switch ON the power to the
coffee maker.
5. Check for leaks once more and repair, if necessary.
NOTE: Installation of this equipment must comply with all local,
state/provincial andfederal plumbing codes.
CAUTION: Place a cup on the drip tray when the coffee maker is
initially filled with water. Approximately 50ml (1.7 oz) of water will
be dispensed by the spout due to the purging of the water system.
* Illustration is for refer ence
purposes only.
Do not over-tighten the inlet
fitting as this may preventwater
from entering the inletvalve.

13
Drain Installation
To install a drain kit on an Espresso Café, the drip tray must first be modified to
remove the float post and create a drain hole.
1. Remove the drip tray grill.
2. Remove the retaining clip that secures the float to the post.
3. Remove the float.
4. Turn the drip tray upside down.
5. Using a ¼” drill bit, align the bit in the centerguide ofthe drip tray and
carefully drill a pilot hole.
6. Change to a 3/8” drillbit and carefully drillanotherhole where the pilot
hole was drilled to enlarge it.
7. This removes the float post from the drip tray and creates a channelfor the
drain system.

14
Drain Installation
8. Connect the drain hose to the drain fitting underthe front ofthe machine.
The hose must go straight down – do not route the hose underneath the
machine.
9. Secure the drain hose to the fitting with the plastic clamp.
10. Connect the otherend of the hose to the drain systemthat will be used at
the installation location.
11. Connect the programmer and powerup the machine.
12. Scrollto the “DRAIN INSTALLED?” menu and press the green <START>
button on the machine.
13. Press the“+” button on the programmer – the lower line on the display
