4.1 Condensate drain
The condensate must be disposed in order to avoid damages to people and things.
Unit discharge tting: the connection must not transmit mechanical stresses and must be performed taking care not to damage the unit
•
discharge tting.
Provide a siphon that, eliminating the negative pressure caused by the fan, prevents the air intake from the discharge duct.
•
The ducting must have a min. slope of 3% to allow the runo.
•
Anchor the ducting with an adequate number of supports.
•
Insulate the duct and the siphon to avoid the condensate drippings.
•
Connect the condensate discharge to a sewerage drainage network.
•
DO NOT use white water or drainage networks to avoid the aspiration of odours in the case of evaporation of water contained in the siphon.
Check at the end of the work, the regular condensate runo pouring some water in the tray.
4.2 Risk of freezing
If the unit or the relative water connections are subject to temperatures close to 0°C:
mix water with glycol, or
•
safeguard the pipes with heating cables placed under the insulation, or
•
empty the system in cases of long non-use
•
4.3 Anti-freeze solution

5 Aeraulic connections
The dimensioning and correct execution of the aeraulic connections are fundamental to guarantee good unit operation and adequate level
of silence in the room.
When designing and manufacturing the ducting, consider LOAD LOSSES, AIR FLOW AND SPEED that must be consistent with the unit features.
Particularly consider that load losses higher than the unit useful prevalence, lead to reduction in ow rate, with consequent unit blocks.
the weight of the channels must not burden on the connection anges
•
place anti-vibration joints between channels and unit
•
connection to the anges and between the various sections of the channels must guarantee air seal, avoiding dispersions penalising the
•
overall eciency of the system
limit the load losses by optimising the path, the type and number of bends and junctions
•
use wide bends evaluating the opportunity of equipping them with deectors (in particular with high air speed or bends with reduced
•
radius)
5.1 Treated air channelling
The internal surface of the channel must be smooth, enable its washing and must not contaminate the air.
Thermally isolate the channels and the anges to avoid energy losses and forming of condensation.
DIFFUSERS INLETS GRILLES
A correct diusion of the air in the room is determining for the level of comfort.
When choosing and positioning the grilles, inlets and diusers, avoid:
excessive air speed
•
forming of stagnant and stratication areas
•
cold air delivery in room
•
forming of localised currents (also due to uneven distribution of air)
•
excessive room temperature variations, vertically and horizontally
•
short circuits of the supply air towards the return air
•
For sound comfort, consider that:
the air diusers must be chosen verifying the sound power generated at nominal ow rate conditions
•
the cut-o to diusers must be carried out with exible elements
•
the return grilles must be widely dimensioned
•
Thermally isolate the channels and the anges to avoid energy losses and forming of condensation.

9.1 General description
Maintenance must be done by authorized centres or by qualied personnel.
The maintenance allows to:
maintain the unit eciency
•
increase the life span of the equipment
•
assemble information and data to understand the state of the unit eciency and avoid possible damages
•
Before checking, please verify the following:
the electrical power supply line should be isolated at the beginning
•
the unit isolator is open, locked and equipped with the suitable warning
•
make sure no tension is present
•
After turning o the power, wait at least 5 minutes before accessing to the electrical panel or any other electrical component.
Before accessing check with a multimeter that there are no residual stresses.
9.2 Inspections frequency
Perform an inspection every 6 months minimum.
The frequency, however, depends on the use.
In the event of frequent use it is recommended to plan inspections at shorter intervals:
frequent use (continuous or very intermittent use, near the operating limits, etc)
•
critical use (service necessary)
•
√ intervention frequency (months) 1 6 12
1 presence corrosion X
2 panel xing X
3 fan xing X
4 coil cleaning X
5 bowl cleaning + sanitisation X
6 outow test X
7 air lters cleaning / inspection X
8 check of the xing and the insulation of the power lead X
9 check of the earthing cable X
10 electric panel cleaning X
11 capacity contactor status X
12 termina closing, cable insulation integrity X
13 voltage and phase unbalancing (no load and on-load) X
14 absorptions of the single electrical loads X
15 test of the compressor crankcase heaters X
16 Checking for leaks *
17 survey of the refrigerant circuit operating parameters X
18 safety valve *
19 protective device test: pressure switches, thermostats, ow switches etc.. X
20 control system test: setpoint, climatic compensations, capacity stepping, water / air ow-rate variations X
21 control device test: alarm signalling, thermometers, probes, pressure gauges etc.. X
* Refer to the local regulations; and ensure correct adherance. Companies and technicians that eect interventions of installation, maintenance/re-
pairs, leak control and recovery must be CERTIFIED as expected by the local regulations. The leak control must be eected with annual renewal.
M06K40A18-00 CKN-XHE2i 7.1-14.2 4
9.3 Unit booklet
It’s advisable to create a unit booklet to take notes of the unit interventions.
In this way it will be easier to adequately note the various interventions and aid any troubleshooting.
Report on the booklet:
date
•
intervention description
•
carried out measures etc.
•
9.4 Standby mode
If a long period of inactivity is foreseen:
turn o the power
•
avoid the risk of frost (empty the system or add glycol)
•
Turn o the power to avoid electrical risks or damages by lightning strikes.
With lower temperatures keep heaters turned on in of the electrical panel (option).
It’s recommended that the re-start after the stopping period is performed by a qualied technician, especially after seasonal stops or seasonal
switching.
When restarting, refer to what is indicated in the “start-up” section.
Schedule technical assistance in advance to avoid hitches and to guarantee that the system can be used when required.
9.5 Outdoor air coil
Contact with the exchanger ns can cause cuts: wear protective gloves to perform the above described operations.
It is extremely important that the battery gives the maximum thermal exchange; therefore, its surface must be cleaned from dust and deposits.
Remove all impurities from the surface.
Using an air pressure gun, clean the aluminum surface of the battery; be careful to direct the air in the opposite direction of the fan air
movement.
Hold the gun parallel to the ns to avoid damages.
As an alternative, vacumn cleaner can be used to suck impurities from the air input side.
Verify that the aluminum ns are not bent or damaged, in the event of damages contact the authorized assistance center and get the ns
straightened in order to restore the initial condition for an optimal air ow.
4 CKN-XHE2i 7.1-14.2 M06K40A18-00
9.6 Indoor air coil
Contact with the exchanger ns can cause cuts: wear protective gloves to perform the above described operations.
The nned surfaces of the cooling coils and, in particular, the condense collection bowls constitute places where microorganisms and moulds
greatly ourish.
It is very important to foresee periodical cleaning with suitable detergents and, eventually, disinfect with sanitising products.
9.7 Electric fans
Check:
the fans and the relative protection gridsare well xed
•
the fan bearings (evident by noise and anomalous vibrations)
•
the terminal protection covers are closed and the cable holders are properly positioned
•
9.8 Condensation collection basin
Dirt or scale can give rise to clogging.
Also, microorganisms and mould can ourish in the bowl.
It is very important to foresee periodical cleaning with suitable detergents and, eventually, disinfect with sanitising products.
Once cleaning is completed, pour water inside the bowl to check the regular outow.

Operation
•
9.10 G4 Folded air lters
It is very important for the air treatment coil to oer maximum thermal exchange: the unit must always work with clean and installed lters.
Cleaning and replacement of lters are very important from an hygienic-sanitary point of view.
Operation with clogged lters leads to a reduction in the air ow rate with malfunctionings and block, up to possible breaks in the unit.
The frequency with which the lters must be checked depends on the quality of the air, the unit operation hours, the dustiness and crowding
of rooms.
Frequency can indicatively vary from WEEKLY to MONTHLY.
It is advised to start with frequent checks, subsequently adjusting frequency to degree of detected dirt.
1. Remove the closing panels
2. Delicately remove the lter avoiding dirtying the area below
3. Wash the ltering jacket in warm water with common detergent
4. Accurately rinse in running water avoiding spilling in the room
5. Dry the lter
6. Insert it back in its seat
7. Remount the closing panels
Old lters, washing wastewater and residues must be disposed of according to the current standards.

Plastic or steel tank (750x750x310 mm) with settling bottom
•
Acid detergent B01212 (code CLIVET C6460316)
•
Protective gloves and goggles
•
Graduated jug
•
Pump for manual or pneumatic spraying
•
Do not use aluminum tanks or galvanized
Foresee a stainless steel frame that keeps the lters lifted from the tank base to have a settling bottom for the muds.
The electronic adjustment is integrated in the lter; maintenance can be carried out without removing it.
Remove the pre-lter by lifting it of about 1 cm and remove it as shown in gure.
1. Position the lter to be washed on a support to facilitate work.
2. Prepare a tank with a solution of B01212 detergent and water at 1÷20.
3. Immerse the lter in this solution.
4. Ensure the solution covers the entire lter.
5. A slight chemical reaction is noticed within 2÷3 minutes with the development of foam. Wait 3 or 4 minutes.
6. Rinse the lter with a jet of water or using a low-pressure water jet machine.
7. Leave the electrostatic cells to dry in a hot room or directly in the sun for a few hours. Keep the cells lifted from the ground using two
metal or wooden laths.
8. Check the ionisation wires before remounting the lter.
The cleaner can be used to clean about 20 lters.
Can be recovered and placed in plastic containers closed; the air oxidizes the cleaner and reduces its eectiveness.
IONISATION WIRES
The impurities can determine oxidation or scaling on the wires, which can be removed using a cloth soaked in alcohol or an abrasive scourer
with very ne grain.
Due to the high voltage powering them, the ionisation wires are subject to wear.
To foresee a yearly replacement OF ALL WIRES avoids unexpected breaks.
In case of break:
1. remove all wire pieces present in the cell and remove the springs stretching the wire
2. hook the spring to the wire eyelet
3. grip the ionisation wire with curved beaks pliers
4. hook the top of the spring with the open eyelet to the wire stretcher rod of the electrostatic cell
5. keeping the ionisation wire stretched, with the other hand hook it to the other wire stretching rod, always by means of the curved beaks
pliers

10.3 Immersed electrode humidier
SUPPLY WATER
The humidier must be supplied with mains water having the following features:
pressure between 0.1 and 0.8 Mpa (1 – 8 bar)
•
temperature between 1 and 40°C
•
Do not use:
water treated with softeners: it can corrode the electrodes and form foam with possible faults/malfunctionings
•
pit, industrial or potentially polluted (chemically or bacteriologically) water
•
disinfectants or anti-corrosive substances mixed with water, as potentially irritating
•
Supplying the humidier with water treated with reverse osmosis ltering system gives the following advantages:
reduces limescale deposits
•
reduces energy consumptions
•
reduces maintenance costs
•
increases the humidier’s duration
•
Check that the lter guarantees a water ow rate higher than the ow rate of the installed humidier.
DRAINAGE WATER
It can reach a temperature of 100°C
It contains the same substances of the supply water but in higher concentration.
As it is not toxic, it can be disposed of with white waters.
Periodical checks
Do not use solvents or detergents to clean the plastic components.
For descaling use a vinegar or acetic acid solution at 20%, subsequently rinsing with water.
