2.1 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.
●
To prevent injuries caused by the fan wheel, a duct at least 2 metres long must always be connected to the fan discharge. The
duct must be fastened in such a way that it cannot be removed without tools.
●
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.
2.2 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 %. 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 95%, 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 anti-freeze 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 paragraph 5.2
3 . 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 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.
●
During transportation the appliance must be secured against falling. The mode of transport must also eliminate any falls of the
appliance or instances of the appliance getting loose.
●
Activities near the unit such as grinding, cutting and other ancillary works that could irretrievably damage the surface or
individual parts of the unit are prohibited.
