Water boiler emptying

Werecommend refreshing the boiler water fromtime to timetoclear impurities that maybuildin theboiler.

•Switch themachineoff at thepowerpoint.

•Opensteam taps andlet all steam out of the boiler. Ensure thepressuregauge needle indicates“0”

•Once ALLsteamand pressure has beenreleased, openthe boiler draintap underthe drip tray.

•Whentheboilerhasbeen drained, closethe boiler drainagetap. Turnthe machine ON and theboiler will re-fill.

Caution

Water drained fromtheboilermay be VERY hot. Be careful to avoidburns.

Position: Inside the machine (on the right

side) there are 2 selectors.

Theleft switch (1) is for thethird group (in 3

group machines).

Switch 1isshipped in position “OFF”. This

means that group 3 isheated up

“staggered” as a “slave” group. This gives

reducesthe peakpower requirement of the

machine and reduces the possibilityof an

electrical powerboard fuse overloading.

Theright switch (2) secures the main boiler

element.Themachine is shipped with

switch (2) in position “ON”.This meansthat

securityis ON, and when the boiler is filling

with water, the main boilerelement will be

OFF to protect it from burning out.

Switches (1)and (2)

Position: Lower right side, blackin colour.

Use: Switches the machine “on”.

The Technologica® can be configured to operate on 30, 20 and 10 Amps bydisconnecting one ortwo main boiler

elements.

On full power, the main steamboiler takes about 10 minutes to heat up, on 20 Amps (one boiler element disconnected)

heat up time isabout 20 minutesand on 10 Amps(twoboiler elementsdisconnected)heat up time is about 40 minutes.

Because the large steam boileroperatesindependentlyfrom theespresso making mini-boilers,the steam pressure can

be configured to give up to 1.5 barssteam pressure which isgood for high volume espresso bars.

Espresso making mini-boilershave a heat up time of onlyfourminutes

Position: Located at the right of eachgroup on the backvertical panel.

The firstgroup (left) and the second are “masters” and the lastone (right side)is a “slave”. This isfor staggeringthe

electrical power requirement to prevent overloads. When the second group (theone in the middle)reaches 80º C, then

the third group ispowered up.

Groupsmaybe switched ‘OFF’ if not required to conserve element lifespans.

Position: Located between the 2 coffee touch pads.

Use: Automatic PID advanced technologytemperature control foreach mini-boiler (350 ml). The temperature controllers

pulse the heat to eachelement to keep and maintain a constant ‘setpoint’ temperature.

The range oftemperatureof each group is from70ºC till 110ºC. It is easyto adjust,and comesin Celsiusor Fahrenheit

degrees. We recommend a set point temperature of 89 º C forGolden Moka® blend. Should you wish to adjust the set

point temperatures, please phone AMANTI on FREEcall 1-800-COFFEE(1-800-263333) from anyland line for technical

assistance.

A red LED will light when the brew water temperatureistoo low and the controller will activate a 1,500 watt mini-boiler

element when the temperature is lessthan the set point. If the temperature slightly exceedsthe set point, that element will

be switched off. The overtemperature value that has been programmed is 0.2º C.

Use: Indicates the boiler pressure (scale 0 to 3 bar) and also thewater inlet pressure (scale 0 to 16 bar).

Target Boiler pressure: between 1 and 1.8 bar(standard valueon the Technologica® machine).

Correct Water pressure with motor-pump = 9 bar.

The maximum pressureof the water inlet without motorcannot exceed 5bar. If this happens ,please ask your plumber to

install a 350 kpa pressure limiting valve..

The portafilter handle should alwaysbe locked into inthe warm ‘group’ in order to keep ithot (working position).Cups

should be located above the machine so theytoo are hot priorto coffee preparation.

With a Technologica® machine, you donot need towait until steam is available before making espresso. The main boiler

isused for water and steam onlyand the mini-boilers heat the waterfor extracting espresso.

To switchon agroup mini-boiler, press the orange push-button switchlocated on the right side of each group and wait

four minutes for the mini-boiler to heat up. From the moment of switchingonthe mini-boilers, thetemperature controllers

start to heat the brewing water. Apart from operating the mini-boilers, the processof coffee extraction is the same asfor

regular machines.

It isnecessaryto wait until the main steam boiler machine reachessteaming heat at over0.5 barsboiler pressure -

approximately 10 to 40 minutes depending on the power configuration of the main boiler element. Oncehot, the main

boiler is able to deliver steam and hot water.

The main boiler must be hot with a boilerpressureabove 0.5 bars.

The farright button on the left touch pad is for steam.

The farright button on the other touch pads are for boiling water dosages out of the hot waterspout.

To deliverhot waterthrough the boiling water spout,press aHotWater button. To stopthe operation early,pressthe

same button again.

Some Technologica® models have a water mixer, i.e. a tap which mixes cold water with the boiling water at the hot water

spout so the temperature of the water dispensed can be lowered so as not to burn the coffee fora long black.

To deliver espresso through a group, press acoffee button on the corresponding touch pad.

The process will stop according to the volumetric dose, previouslyprogrammed.

To stop the operation early, pushthe same button orany other dosage or the continuous‘C’ button on the same touch

pad.

On the left hand touchpad, push and hold the ‘C’ continuous dosage button forfiveseconds.

The LEDs will light indicating that the machine is in programming mode.

Push the dosage button that you want to program.

The ‘C’ programming LED will be lit as well as the button being programmed.

Use a handle dosed with fresh coffee – the coffee in the handle willabsorb water.

Use a medicine measure under each spout to measure accuratelythe liquid dispensed from each spout.

When the dosage is correct(NOTmorethan 20 ml+ crema from aspout), push the same button to programand

rememberthe dosage.

Note 1 : The process can be repeated as manytimes asdesired.

Note 2 : All groupsto the right of the left (first) group, are programmed when the left group isprogrammed. If you want

different dosages on the second orthird group, then those touch padsneed to be programmed independently.

Note 3 : If you need to restart the process because of an error, wait 5seconds

and tryagain.

Pre-Infusion wets the coffee in the basket prior to extracting espresso. Some aficionadossaypre-infusionmakesbetter

coffee although we have found thishard to verify.

Pre-Infusion is an option, so it can be programmed easilyat 0.2 secondsordeleted.

The farright button on the left touch pad is for steam.

The farright button on the other touch padsare forboiling water dosages out of the hot waterspout.

Programthe hot water dosage, in the same time wayas programming coffee dosages.

The boiler hasalevel probe, which informs the main electroniccontrol board about the level of water inside the boiler. If

the level probe isnot touching water in the boiler, the filling electro valve will open and the boiler will be refilled. Duringthis

processthe main boiler elementis alwaysofffor safety.This isparticularlyimportant when operating the machine for the

first time.

Filling the main boiler usuallytakes4to 5 seconds,and 2or 3minuteswhen first installing the machineorwhen

emptying andfilling again the boiler.

The machine has electronic water level control and electronic filling. Thisavoids problemsassociated with water level

sight glasses. A boiler fill LED informs the operatorof boiler filling.

The Technologica® uses Procon brand pumps that are veryreliable. Usually, espresso machinesare connectedto a

mains water supply.Ifthe operator wishesto use tank water, aone wayvalve is recommended to prevent water return to

the tank. Failure to use a one wayvalve on the waterline from tankwater mayresult in damage to the pump.

Hot water can be programmed to workwith pump or with no pump.Instructions on how toprogram thisfeature on the new

blue touch pads maybe obtained from AMANTI.AMANTI maybe contacted on FREEcall 1-800-COFFEE (1-800-

263333) from anyland line.

The internal parametersofthe temperature controllers can notbe changed, because the PID program controls them, and

this program can onlybe modified by AMANTI.

The set point can be changed bythe operator.

Each controller shows two temperatures: Red numbersand Green numbers.

The Red numbers indicate the set point / programmed temperature i.e. the temp we want, and the Green numbers

indicate the real temperature currentlyin the mini-boiler.

To change the temperature that we want in each group, the value shown bythe RED numbers must be changed.

Robusta beans requirea higherbrew watertemperature arount 95º C whereasAMANTI Super-Gourmet, 100% specialty

beans require a brewwater temperatureof only89º C

If the boiler isnot used for dispensing much hotwater, then it isrecommended to drain the main boiler from time to time,

to clear waterimpurities that mayaccumulate in the main boiler.

Danger

It is necessaryto make sure the boiler has no pressure and iscold before draining the main boiler.

If the boileris hot and underpressure, boilingwater maybe sprayed onto the operator.

Position mainswitchin position “0” off. Open both steamwands and release all steam. Checkthat the main boiler

pressure gauge reads zero “0”.

Oncethemachine hasno pressurein the boiler, open the blackboiler emptying tap situated under the driptray.(Some

machinesmayhave had the taptaken off to prevent accidental opening while the boileris pressurized).

Oncethe boiler has been drained, closetheemptying tap and both steam wands.When the machine isswitched on, the

boiler will fill automatically.
