5.6 Installation of filters and RO membrane
WARNING!
The system start-up must be carried out or monitored by persons approved and trained by Condair. Errors in the start-up phase may ultimately result in illness, injury and death of humans.
CAUTION!
When fitting water filters, RO membranes, hoses and other components in direct contact with water please, wear sterile gloves or touch only the packing paper to keep the filter bacteria-free. Remember to wash your hands!
CAUTION!
Commissioning of the pump should be the last thing performed at an installation site. When the pump has run with water and the preservation fluid (windscreen wash) has been flushed out, it should always be kept on (summer and winter) in order to keep the system hygienically clean by allowing it to run its automatic flushing.

5.6.1

Commissioning work
Disconnect the power before starting any commissioning work.

Install filters The filters are already packaged inside their housings.

Note: The front right filter will house the granular active carbon (GAC) filter, the front left filter will house the silt filter. Check the configuration before installation. See picture.
1. Remove the housings from the filter heads.
2. Take off the plastic covers. 3. Remove the plastic packaging from the
filter elements. 4. Place the filters back into their housings. 5. Screw the housings back into their heads
and tighten with the wrench.

Warning: When installing the RO membrane, you should pay attention to the direction of the membrane. Put the end with the two O-rings into the housing first. When installing correctly you only need a little force to put the reverse osmosis membrane into the housing. If you encounter too much resistance, please do not force installation. Doing so may cause permanent damage to the membrane shell or membrane components.
4. Remount the lid. Tighten it using the wrenches. 5. Reconnect the water inlet pipe to the push fit.

26 Installation Condair RO-H

5.6.3 RO membrane flush and startup, RO-HM
CAUTION!
The first time a new RO membrane is to be used, it is important to flush out any preservation fluids so that they do not end up in the system.
After confirming that the water route connections are correct, confirm that inlet water, power supply, drain and connection to the application are installed. The latter should not be connected yet. Then follow these steps to commission/troubleshoot the unit (see graphic chapter 5.3.5):
1. Open the tap water inlet valve [1], close the storage tank valve [5] and plug in the power source. An automated, 30-second flushing process starts; water will start to drain through the discharge outlet. Do not connect to humidifier yet!
2. Wait for the water treatment system to operate stably (about 5­10 seconds), check each connection to make sure it is secure, see if there is any leakage from the membrane shell, filters, etc.
3. Connect the RO line to the humidifier unit. Make sure the inlet valve of the unit is closed. Wait approximately 30 seconds, check whether the RO stops producing water.
Open the application’s inlet valve. If no water is flowing after 5­10 s, check if ­ the water line is open. ­ the RO is powered on. ­ concentrate water is flowing. 4. Close the RO inlet valve [1]. After a short time observe whether the RO has stopped operating. Open the RO inlet valve [1] again. 5. Flush the RO unit for at least 10 min before using any water for humidification. Reason: the reverse osmosis membrane element package contains a small amount of protective solution and the post-activated carbon filter will emit activated carbon powder the first time it is used. Now close valve [8]. 6. Before starting the commissioning of the humidifier unit, open the tank valve [8] and let the tank fill (15 min for 3.17 gal tank, 18 min for 4.8 gal tank).
Notes on commissioning 1. The major components of the RO membrane are plastic. When using the product always observe the integrity of the water treatment unit to ensure safe use. 2. When you start operating the water treatment system the pure water TDS value may be a little high. After running for some time the TDS value for pure water will gradually decrease until it is stable. 3. Once the RO has been installed, the inlet ball valve should never be closed except for short periods of maintenance work. If the ball valve is closed for longer periods, bacterial contamination will happen in the pipes (bacterial contamination on standstill) which may cause serious bodily harm when the water thereafter is used for humidification. When the RO is not in use, the highpressure switch will automatically cut off the water supply automatically.
In these “usage methods”, “usage” refers to when the power supply is connected and/or the inlet water ball valve is open so the water treatment system is in a working condition.
Installation Condair RO-H 27

5.6.4 Equipment protection
Pressure switch (inlet water) The RO-H has a pressure switch, which monitors the inlet water pressure. If the inlet water pressure drops, the controller will stop the pump, thus protecting it against dry running. If the water pressure drops, the starter screen will display a zero, equalling `PM Water pressure too low’.
