Safety information

The device can be used by children over 8 years old and people (including children) with reduced

physical, sensory or mental capabilities, or lack of experience or knowledge, if they have received

guidance or information on how to use the device safely and understand the risks that may occur.

Children must not play with the device. Cleaning and maintenance must not be carried out by

children without the supervision of an adult.

Electrical installations carried out in connection with the drier installation must be done by a

qualified electrician in accordance with local and national regulations.

1. The drier is only intended for indoor use.

2. The drier must not be covered during operation, as this may cause overheating and fire.

3. The drier's protective covers and shields must always be in place during operation.

4. The drier must not be used as a worktable, trestle or stool.

5. The drier is not intended to be stood or climbed on.

6. Never operate the drier without installing the filter as this may damage the drier. Ensure that

the filter is clean. If it is blocked, the machine may overheat.

7. Avoid sucking oil, grease or similar into the drier.

8. The drier may not be used in areas where it can produce explosive gases.

9. Do not insert objects into the intake or exhaust vents as this could damage the drier and

people.

10. The machine must be used and transported upright.

11. The drier must always be upright when it is in operation. Place the drier on a firm and flat

surface so that it cannot overturn.

12. Do not damage the electrical cable. Extension cables must be intact and of the right quality

and dimension. They must nor run through water or over sharp edges.

13. Never carry or drag the drier by the electrical cable or the drain hose.

14. Using electrical equipment in very damp or wet conditions can be dangerous. Do not operate

the drier if it is standing in water.

15. Always use an earth-fault breaker to minimize the risk of electric shock.

16. Water must not encounter the drier's electrical components. If it does, ensure that they are

dried thoroughly before the drier is used again.

17. Never open the drier for cleaning or service without first ensuring that the drier is

disconnected from power.

18. Repairs and maintenance of the drier's cooling system must be performed by a qualified

refrigeration engineer.

19. Repairs and maintenance of the drier's electrical system must be performed by a qualified

electrician.

20. The drier must not be used with accessories other than those described in this manual or

approved by Corroventa Avfuktning AB.

21. The dehumidifier must be placed at a distance of at least half (0.5) meters from the walls and

ceilings to ensure that the air can circulate.

22. The equipment must be scrapped in accordance with local regulations.

Contact the supplier of this drier for further advice on the safety and use of the product.

Relative humidity and its impact on materials

All air contains a greater or lesser degree of moisture. We cannot see it with the naked eye until it

appears in the form of small water drops against a cold metal or glass surface for example. However,

before it is visible, moisture is already causing problems by affecting materials and manufacturing

processes, causing corrosion and growth of micro-organisms.

Air moisture is measured and usually given in relative humidity (% RH). It is a measurement of how

much water vapour the air contains over how much it can hold in total at a given temperature and

pressure. The higher the temperature, the more water the air can hold, but it is the relative humidity

that is calculated and must be controlled to prevent corrosion or mould growth.

At 100% RH the air is saturated, and the moisture falls in the form of small water droplets. Steel

corrodes at 60% RH and at 70% RH there is a risk of mould. A rule of thumb is that 50% RH is a good

climate for most materials.

•The dryer contains Propane (R290), a natural refrigerant with low environmental impact.

•The refrigerant gas is flammable.

•Ensure that the cooling circuit's pipelines are not damaged. In case of damage to the

cooling circuit, carry the machine out or ventilate the space and avoid naked flames or

other spark-generating sources.

•Note that the refrigerant gas is odourless.

•The machine must always be stored upright, frost-free and in a ventilated area without

sources that may cause sparking or near flammable substances.

•Do not use agents/methods to accelerate defrosting or cleaning other than those

recommended by the manufacturer.

•The cooling circuit must not be punctured.

How to choose dehumidification technique for a given situation

Compared to the adsorption principle, condensing dehumidification has the advantage of not having

to route the wet air out from the room.

As a general aid to selecting technology for a given drying situation, it can be said that condensing

dehumidification is the primary choice for drying in warm and humid spaces where drying must be

achieved in an energy efficient way and when it is difficult to route the wet air out. One of the

advantages over the adsorption technique is that the heat is not dissipated with the wet air from the

room.

An adsorption dehumidifier with air-cooled condenser like L4, bridges these properties by working

within a large area, including the primary area of the condensing dehumidifier. In other words, it is

the best option for room drying at low temperatures, ideal for emergency damage and construction

dehumidification.

As the graph above shows, condensing dehumidifiers are used in hot and humid spaces if room

drying is required.

How the drier works

The integrated fan (7) circulates the room air through the drier. When the moist air passes through

the evaporator (2) it is cooled down to dew point and condensation water is deposited. The water

runs down into the collection receptacle via a condensation filter (4). The condensation water is

evacuated from there automatically by the integrated water pump (8), which can manage a height of

up to five meters. The pump runs continuously and if it does not manage to drain the water because

of a pinched hose or other fault, the overflow sensor (5) activates, which stops the machine.

The dry and cold air then goes through the condenser (3) where it is heated, partly by the compressor

heater (6) and partly by the energy recovered during the previous transformation of water vapour to

water. The dry and hot air is then blown into the premises again.

For optimal operation, machine defrosting is demand controlled and is only activated when the

temperature and humidity conditions are such that frost forms on the cooling coil.
