Installation and maintenance instruction 7 FläktGroup DC_8642GB 20180131_R0 Specifications are subject to alteration without notice ITEMS TO CHECK WHEN MAKING ADJUSTMENTS Water: Determine the proportion of calcium and bicarbonate in the water, and its pH level. This information can be obtained from a water analysis or from the local water company. Enter the values obtai- ned in chart 1 on page 4 to determine which zone the water can be classified. If the water quality is in zone 4 a water softener must be used. Testing operation of humidifier: – Turn on the external switch. – Give the start signal to the humidifier by closing input TF1 (if this signal is interrupted the humidifier will stop and the water will drain out). – The tray should only start to fill with water when there is a need for humidification, i.e. when the RH1 input closes. Now check: – that the humidifier starts to fill with water. – that the pump starts and pumps water (input RH1 must be closed). If there is no water flow, change the direction of rotation, see figure 3. – Preset the required supply water flow rate according to Table 3. This is done by setting the adjustment screw on the flow con- troller, see figure 4. – that water sprays out of all the holes in the spray pipe(s). Use a needle to clear any clogged holes. If the pipe is clogged with dirt, remove the end plugs, pos. 16, fig. 1, clean the spray pipe with a round brush, then flush it clean. – that the supply flow stops when the water reaches level A. – that the water bleed-off rate is correct. Open the outlet valve, figure 2, by holding in the left arrow key on RC1. When the water level has fallen below level B the valve should open fully and the display should show ”Emptying”. When the water drops below level C the water inlet should open, and after the preset time the drain valve should start to close. When the water reaches level C the pump should stop briefly. The tray will then refill with water. Droplet eliminator The droplet eliminator must be installed in the correct direction of the air flow, see the arrow on the droplet separator. Table 3 gives the amount of water that the circulation pump must be set to. It is not the water consumption.

Installation and maintenance instruction 8 FläktGroup DC_8642GB 20180131_R0 Specifications are subject to alteration without notice WATER BLEED-OFF Water consumption consists of the useful evaporation and essential water bleed-off flow. This bleed-off flow is necessary to reduce the concentration of salts in the circulating water. If the salt concentration becomes too high, salts are precipitated out in the humidifier fills, which will reduce the performance and working life of the humidifier. Chart 1 can be used to determine the appropriate bleed-off flow, by determining zone for the current water quality. Then set the appropriate bleed-off flow to ensure that the water in the tray is kept clean it is recommended that it is drained and flushed once every 24 hours (timing is preset at factory for 12.00–12.15). If high demands are made on hygiene or if humidification require- ments are high for an extended period, i.e. Δ x > 8 gram per kg of air (90 % humidifier) or Δ x > 5 gram (60 % humidifier), it is re- commended that an extra drainage and flushing cycle is added in each 24-hour period. It may be necessary to extend the dilu- tion time, see table 4. The value (T) is set using the display.

CHART 1 Zone 1 is the safe zone, where the water is soft or demi- neralised. Zone 2 is the lower part of the transition zone, where the water is normally of drinking water quality. Zone 3 is the upper part of the transition zone, where the water is relatively hard. Zone 4 is the precipitation zone, where the water is very hard. The water must be partially demineralised so that the result will be a quality that corresponds to zone 2–3. The water should not however be demineralised so much that it falls into zone 1. EXAMPLE Data from the local water works: pH = 7,6 Bicarbonate 70 mg/l Calcium 30 mg/l Chart 1 indicates zone 1 (the safe zone) Apart from the risk of lime precipitation, the concentrations of chloride (Cl) and copper (Cu) must be checked. The concentration in fresh water must not exceed 50 mg/l for chloride and 0.02 mg/l for copper. HOW TO USE THE CHART Enter the chart on the right hand side with the bicarbonate (A) rate and the Ph (B) and find the intersection (C). run a line over the chart with the calcium rate (D) and find the intersection in the applicable zone.

PRESET LEVELS AND PARAMETERS CHOSEN TO SUIT HUMIDIFIER SIZE (CAN BE CHANGED WITH PASSWORD) Example S = Installation height of ultrasound sensor above the bottom of the water tray. A = Max. water level for filling. C = Min. water level (Pump stopped). F = Adjusting/scaling sensor output. B3 = Level for zone 3 B2 = Level for zone 2 B 1 = Level for zone 1 CP = 1-4 Function assigned to pump(s) when inputs for hygro- stats RH1 and RH2 are closed. 1 pump, 1 step CP = 1, RH1 starts CP1, RH2 is disconnected. Alarm from CP2 is interlocked. 2 pumps in parallel CP = 2, RH1 starts both CP1 and CP2, (default setting). Can be used even if just CP1 is fitted. 2 pumps, in sequence (special) CP = 3, RH1 starts CP1, RH2 starts both CP1 and CP2. 2 pumps, mode (special) CP = 4, RH1 starts CP1, RH2 starts CP2, RH1+RH2 starts both CP1 and CP2. IMAGE 7. SETTING THE CLOCK The clock must always be reset if power to the humidifier has been cut off for around 100 hours or more. The clock switches automatically between summer/winter time according to EU standard. To change the time, do as follows: Press arrow down so that the clock time flashes. Press OK. The date and time will now be displayed. Use the arrow keys to move the flashing field and change the relevant value using the + and – keys. When the date and time are set, press the OK key. IMAGE 8. TO SET THE INACTIVITY TIME SETTING The water in the humidifier will be emptied if the humidifier has been inactive for a period longer than the preset inactivity time (no need for humidification). When the RH1 input closes, the pump starts up (if the water level is not too low). When the RH1 input opens, the pump stops and a time counter begins counting the time that the humidifier is inactive ”Not in operation” and the tray is emptied of water. When the RH1 closes again, the time counter is reset to zero, the tray is filled with water and the pump starts up. To change the inactivity time setting, proceed as follows. Press the arrow-down button to cause the value to flash in the display. Press the + or – button to change the setting to the value of your choice. Then press OK. S = 1 2 0 B 3 = 5 3 A = 7 3 B 2 = 3 3 C = 2 0 B 1 = 2 8 F = 5 4 0 C P = 2 Caution! The pumps are interlocked if the water level is low, if the humidifier is not running and if there is an alarm from the relevant overload protection.

Installation and maintenance instruction 14 FläktGroup DC_8642GB 20180131_R0 Specifications are subject to alteration without notice TO ZERO CALIBRATE THE ULTRASOUND SENSOR The sensor is zeroed by FläktGroup with an empty water tray. If it is necessary to change the zero calibration to suit future needs this can be done by adjusting position of the sensor by means of the lock nuts. The sensor must reach working temperature before calibration, i.e. the humidifier must be allowed to run for at least 15 minutes after switching on. The display may give a reading that is out by a few millimetres during the warming-up period. ALARMS There is a potential-free group alarm output inside the junction box. The alarms that appear on the monitor screen are: Alarm level The water level is continuing to rise above the maximum level ”A”. The most likely reason is that the solenoid valve MV1 is not closing. The alarm stops after five minutes. The water level does not reach the maximum level ”A” during filling. The most likely reason is that the solenoid valve MV1 is not opening, the water tap is turned off or the drain valve SV1 is not closing. The alarm stops after 30 minutes. The sensor has detected unreasonable values, outside its detection rage, is not correctly aimed at the water surface or has stopped working. This fault is also shown by the sensor LEDs both glowing red. The alarm stops after five minutes. Alarm CP1-Q1 or CP2-Q2 Has been initiated because the overload protection for circula- tion pump CP1 or CP2 has tripped. Resetting alarm Press the Esc key to reset an alarm.
