  • Page 11: C Description Of The Appliance

    DESCRIPTION OF THE APPLIANCE The main functions of the machine, and its relative parts, are described below, with a view to ensuring its maximum performance. COFFEE DISPENSING (K-Kwts-S-M-C-B) Independent dispensing groups with predosed or manual selections. Filterholders for one or two cups. DISPENSING OF HOT WATER AND STEAM (K-Kwts-S-M-C-B) The machine has one or two steam wands and a hot water dispenser which allows the use of large milk or water containers thus guaranteeing good general ergonomics.
  • Page 12 CONTROL OF WATER TEMPERATURE IN THE BOILER (K-Kwts-S-M-C-B) This keeps the temperature of the coffees constant as opposed to the temperature and the pressure of the steam. Consequently, it also controls the pressure in the boiler. STABILIZING THE BREWING TEMPERATURE (K-Kwts-S-M-C-B) Each dispensing group has a heating circuit for brewing water that functions with a heat exchanger.
  • Page 13 UPPER CUP HEATER TRAY (K-Kwts) Models equipped with larger cup heater trays and electric heating with automatic temperature control. The heating can either be enabled or disabled. DRIP TRAY (K-Kwts) Improves the draining and cleaning of the work counter. Avoids blocking of the drain. USER ALERTS (S-M-C-B) The machine can give the user a series of alerts through different LED light on/off combinations for each coffee dispensing button, on each of the two or three groups on the machine.
  • Page 14 Customer requirements Special Programming is the exclusive responsibility of the dealer’s specialized technician who will have been specifi cally trained by ELEKTRA to do so. Special Programming should be carried out on the dealer’s premises prior to installation.
  • Page 15 UNPACKING Packaging is carried out with the aim of protecting the machine from damage during transportation. The packaging materials used are recyclable. They are, therefore, chosen according to environmental protection criteria and ease of disposal, the latter process being geared at further integration in productive cycle materials.
  • Page 16 Installation must be carried out exclusively by a specialized technician from the Technical Assistance Service. The company Elektra declines any and all responsibility for tampering or interventions carried out by non authorized persons. Such intervention automatically renders the guarantee null and void.
  • Page 17 WATER SOFTENER CONNECTION (Kwts) The machine must only be used with the three types of special water softener supplied by ELEKTRA, i.e.: 8 litre ELEKTRA water softener 12 litre ELEKTRA water softener 16 litre ELEKTRA water softener No other type or brand of water softener may be used with this model.
  • Page 18 DRAIN CONNECTION (K-Kwts-S-M-C-B) The machine has a rubber connecting pipe with pipe-end fi tting, approx. 1.5 metres in length. This pipe must be made to fl ow into a fi xed drain manifold with a minimum internal diameter of 35 mm located underneath the machine work counter. The space created by difference in diameter of the two pipes inserted one into the other must be left free for the venting of air during the discharging of the water.
  • Page 19 FILLING THE HYDRAULIC CIRCUITS (K-S-M-C-B) 1) Ensure that the water supply is turned on. 2) Switch on the machine by turning the main switch from position “0” to “1”: the machine goes on and loads water into the boiler, while powering the heating elements. FILLING THE HYDRAULIC CIRCUITS (Kwts) Before switching on the machine, fi...

  • Page 22 Measure the hardness of the water supply using the ELEKTRA kit provided, expressed in French degrees (°F), and store it through Basic Programming (see chapter “G – USE”).
  • Page 23 ADJUSTING THE SALINITY OF THE BREWING WATER (Kwts) With a view to obtaining the best “quality in the cup”, the taste of the brewing water may be varied by adjusting its salts concentration. Contact Technical Assistance. PROGRAMMING OF COFFEE DOSES (K-Kwts-S-M-C-B) Through the guided making of single sample coffees and the setting of doubling factors, the desired doses on each of the four automatic keys for each group may be stored.
  • Page 24 ATTENTION: (USA NSF requirements) The unit must be fl ushed after 12 hours of inactivity. With reference to the hydraulic scheme enclosed on chapter “E – INSTALLATION”, once the suitable boiler pressure for correct use of the appliance has been reached and before putting it into service, the machine must be be fl...
  • Page 25 USE OF THE WORKING AREAS (K-Kwts) The machine is divided into a coffee dispensing area on the right and a steam and hot water dispensing area on the left. It is thus possible to work with containers of up to 2.76 inches in height or up to 5.71 inches in height, depending on the heights of the work counters used (dispensing groups) and with containers of up to 5.91 inches in height (water and steam wands).
  • Page 26 WARMING THE CUPS (S-M-C-B) Place the cups on the upper cup tray and remove them when they are needed, according to a rotation system that allows them suffi cient time to heat. Do not place cloths between the tray and the cups. Do not cover the cups with cloths or other materials WARMING THE CUPS (K-Kwts) Press the button marked with the symbol...
  • Page 27 MAKING TEA – CAMOMILE TEA ETC. (K-Kwts-S-M-C-B) Draw hot water from the boiler using the water valve wand, then add the bag required to obtain the drink to be made. USING BASIC PROGRAMMING (S-M-C-B) 1) Insert the key in the lock on the control panel, gently press and turn it clockwise: the machine automatically enters a state of partial operation suitable for programming.

Rinse the fi lters and fi lterholders in boiling water in order to remove the fatty deposits of the coffee.
  • Page 36 REGENERATION OF THE WATER SOFTENER RESINS (K-S-M-C-B) After the water softener resins have removed a given quantity of calcium and magnesium salts from the water (water hardness) they rapidly become saturated, losing their softening capacity. This capacity is completely restored through regeneration, which is carried out by washing in a salt and water solution.
  • Page 37 REGENERATION OF THE WATER SOFTENER RESINS (Kwts) When the following alert appears on the display: “LOAD SALT AND PRESS ENTER-MACHINE ON”, proceed as follows: 1) Open the water softener cap 2) Pour the amount of common coarse salt indicated on the packet label into the water softener, i.e.: - 8 litre water softener 1.0 kg...

    If the problems persist, contact Technical Assistance. Do not carry out repairs directly on the appliance. The company ELEKTRA declines any and all responsibility for tampering or interventions carried out by non authorized persons. Such intervention automatically renders the guarantee null and void.
  • Page 40 WATER COMES OUT OF THE STEAM WAND (K-Kwts-S-M-C-B) This means that the boiler is completely full of water instead of containing a certain quantity of steam. The possible causes of this are: Fault in the boiler water inlet solenoid valve. Electrically isolating incrustation on the level probe or interruption in its electrical connection.
  • Page 41 A DISPENSING GROUP STARTS UP ON ITS OWN (M-B) The membrane pushbutton panel has a damaged key or water has entered it: Identify the faulty key and, by switching it off and on repeatedly, try to disable it and do not use it any more. Make the water inside the membrane evaporate by drying it with a hair dryer.
  • Page 42 ONE DISPENSING GROUP DOES NOT HEAT SUFFICIENTLY (K-Kwts-S-M-C-B) There is an obstruction to the passage of the brewing water, i.e.: Gigleur protection fi lter clogged. Group natural heating circuit clogged with scale deposits. Contact Technical Assistance THE GAUGE SHOWS A BOILER PRESSURE NOT BETWEEN 0.6 AND 1.6 BAR (S-M-C-B) Unless this value exceeds 1.8 Bar, in which case switch off the machine and contact Technical Assistance, this is a fault that does not negatively affect the use of the machine.
  • Page 43 NO SALT LOADING (Kwts) If “ENTER” is erroneously pressed before the salt is loaded in the water softener, do not try to open the water softener. Proceed as follows: 1) Wait, while continuing to operate the machine: after approx. one hour, the following alert will be displayed: “WATER SOFTENING SYSTEM FAULT - MACHINE ON - REPAIR”...
  • Page 44 THE DRIP TRAY IS FULL AND OVERFLOWING WITH WATER (K-Kwts-S-M-C-B) 1) Clean the drain box and use a metal wire to free the drain pipe of residue. 2) Eliminate any sagging or strangling of the fl exible drain pipe, ensuring that it is always angled downwards in a straight and even manner.
