EVERY 6 MONTHS
BEFORE MAINTENANCE PROCEDURE
Before starting the 6-month maintenance procedure, make the following
preparations.
1.
Turn off your machine by moving both the red and white switches to
the “off” position.
2.
Turn off water supply, either at the source or at the filtration system.
3.
Disconnect machine from power source.
4.
Lift to remove cup tray assembly.
DR AINING STEAM TANK
As steam is produced and exits the wand, minerals in the water are left
behind build up inside the boiler. The steam tank needs to be drained
periodically to remove these excess minerals. For assistance with this
procedure, refer to parts diagrams.
PARTS AND TOOLS:
• 1/4
"
teflon or poly tubing
• Wrench
PROCEDURE:
1.
Follow instructions in above video to remove the machine’s left side
panel.
2.
Locate the shutoff valve on the lower left side of the steam boiler.
Insert a 1/4” teflon tube into the quick-connect fitting located after the
shut-off valve, pressing firmly until the tube clicks into place.
If teflon tubing is not available, poly tubing may be used instead. If
using poly tubing, see note under step 7 before beginning step 7.
3.
Aim the open end of the 1/4” teflon tube into a sink or bucket, then
secure the tube or weigh it down with a heavy object.
4.
Use a wrench to open the shut-off valve. The steam in the boiler will
push all of the water in the tank through the teflon line and into the
drain.
If using poly tubing, do not open the valve fully; high pressure
will damage tubing.
5.
Allow the tank to drain, then continue with steps 6-. Other
maintenance tasks may be performed during this time.
6.
Close the shut-off valve and carefully remove the tube from the quick-
connect fitting.
7.
Reinstall the side panel.
8.
Reconnect power and turn on water supply.
9.
Move brew and steam actuators to the “on” positions.
10.
Engage red power switch to refill tanks.
11.
When water begins to flow from groupheads, indicating that the tanks
have filled, move brew actuators to the “off” positions. Keep steam
actuators in the “on” position.
12.
Engage white power switch to turn on heating elements.
13.
When steam begins to exit wands, close steam actuators and allow
machine to fully heat.
STEAM VALVE PIN O -RINGS
When the steam actuator is moved into the “on” position, it pushes a
brass pin into the steam valve, which causes the valve to open and allows
steam to flow. The two (2) o-rings on the steam valve pin should be
replaced every six (6) months.
PARTS AND TOOLS:
• Steam Valve Pin O-Rings
• Flat-head screwdriver
• 3/4
"
socket wrench
• Pliers
• Pick or awl
PROCEDURE:
1.
Remove top/side first?
2.
While holding the corresponding nut on the machine’s interior with a
3/4
"
socket wrench, use a flat-head screwdriver to loosen and remove
the shoulder bolt.
3.
Use pliers to remove the steam valve pin (#7).
4.
Use a pick or awl to remove the o-rings (#8) from the steam valve pin
and discard them. Put the new o-rings on the pin.
5.
Rub Slayer lubricant on the pin and return the pin to the steam valve.
