1.1.

General safety

Only adults sufficiently familiar with the operation and maintenance manual may operate the

equipment.

The user must not tamper with or modify any part of the equipment, particularly the power supply

lines!

Only professional service technicians with relevant qualifications may perform equipment repairs.

Unprofessional repairs are very risky and may result in loss of warranty.

Before opening the equipment´s door for cleaning, filter replacement or general maintenance

always make sure that the equipment is disconnected from power supply and prevent its

reconnection by another person.

For rules of connecting air duct please see chapter 4.5.

If the equipment has been out of operation for a prolonged period of time, extra care should be

taken when putting it back into operation.

1.2.

Operational safety

The indoor version of the unit is intended for a basic environment - ambient temperatures must be

between +5 and + 55 °C with relative humidity up to 60 % (60 % relative humidity up to 20°C). If

the appliance is located elsewhere, its sufficient protection must be ensured.

The appliance may be operated within the temperature range of ventilation air between -25 and

+40 °C with relative exhaust air humidity up to 80%, in an environment where there is no risk of

fire or an explosion of flammable gases and fumes, and air transported must not contain organic

solvents or aggressive substances that might damage mechanical parts of the unit. If there is a

danger of such gases and fumes temporarily entering the duct system (e.g. during floor bonding,

painting), the unit must be switched off sufficiently in advance.

In the event of a failure the appliance must be disconnected from power supply as soon as

possible!

The water chiller in all versions must be filled with an antifreeze solution with sufficient thermal

resistance, or it must be drained for the period during which outdoor temperature might fall below

+5°C. We recommend draining water from the chiller with pressurized air, not using a gravity flow!

Appliances with hot water heaters

Must be permanently connected to power supply to provide for the anti-freeze protection of the

hot water heater. In the case of a prolonged power outage the heating medium must be

drained from the hot water heater including the control set. We recommend draining water

from the heater with pressurized air, not using a gravity flow!

It may only be operated if the heating system including the hot water heater and control set

are filled with a heating medium and air bled; also applies to periods outside the heating

season! In the case when the heating system including the hot water heater and control set

are not filled with a heating medium, the appliance must be drained of the remaining heating

medium, dried properly and disconnected from power supply.

The appliance is designed for environments with Class ETA 1 extract air; in environments with

extract air Class ETA 2 and ETA 3 it is necessary to comply with conditions specified in the

chapter 4.2.

S t o r a g e a n d t r a n s p o r t

The appliance may only be stored in dry, covered places with ambient temperatures between

-25°C and +55 °C in such a way that its surfaces that are to be in contact with transported air

remain protected against the weather and stay dry and clean.

Packaging may not be removed until immediately before the installation of the appliance in its

operating position. If that is not the case, all parts must be checked for cleanliness before

installation and thoroughly cleaned if necessary.

The appliance must not contain any operational liquids (e.g. water in the hot water heater, water

chiller etc.) during storage and transport.

The appliance may only be transported on handling blocks (included). During transportation the

appliance must be protected against mechanical damage and water penetration and all openings

must be covered with protective covers.
