1.6  Safety notes for the operator

The operational safety of the units and compo-

nents is only assured providing they are used as

intended and in a fully assembled state.

n

The units and components may only be set up,

installed and maintained by qualified per-

sonnel.

n

Protective covers (grille) over moving parts

must not be removed from units that are in

operation.

n

Do not operate units or components with

obvious defects or signs of damage.

n

Contact with certain unit parts or components

may lead to burns or injury.

n

The units and components must not be

exposed to any mechanical load, extreme

levels of humidity or extreme temperature.

n

Spaces in which refrigerant can leak sufficient

to load and vent. Otherwise there is danger of

suffocation.

n

All housing parts and device openings, e.g. air

inlets and outlets, must be free from foreign

objects, fluids or gases.

n

The units must be inspected by a service tech-

nician at least once annually. Visual inspec-

tions and cleaning may be performed by the

operator when the units are disconnected from

the mains.

1.7  Safety notes for installation,

maintenance and inspection

n

Appropriate hazard prevention measures must

be taken to prevent risks to people when per-

forming installation, repair, maintenance or

cleaning work on the units.

n

The setup, connection and operation of the

units and its components must be undertaken

in accordance with the usage and operating

conditions stipulated in this manual and comply

with all applicable regional regulations.

n

Local regulations and laws such as Water

Ecology Act must be observed.

n

The power supply should be adapted to the

requirements of the units.

n

Units may only be mounted at the points pro-

vided for this purpose at the factory. The units

may only be secured or mounted on stable

structures, walls or floors.

n

Mobile units must be set up securely on suit-

able surfaces and in an upright position. Sta-

tionary units must be permanently installed for

operation.

n

The units and components should not be oper-

ated in areas where there is a heightened risk

of damage. Observe the minimum clearances.

n

The units and components must be kept at an

adequate distance from flammable, explosive,

combustible, abrasive and dirty areas or

atmospheres.

n

Safety devices must not be altered or

bypassed.

1.8  Unauthorised modification

and changes

Modifications or changes to units and components

are not permitted and may cause malfunctions.

Safety devices may not be modified or bypassed.

Original replacement parts and accessories

authorised by the manufactured ensure safety. The

use of other parts may invalidate liability for

resulting consequences.

1.9  Intended use

Depending on the model, the units and the addi-

tional fittings with which they are equipped are only

intended to be used as an air-conditioner for the

purpose of cooling or heating the air in an

enclosed space.

Any different or additional use is a non-intended

use. The manufacturer/supplier assumes no lia-

bility for damages arising from a non-intended use.

The user bears the sole risk in such cases.

Intended use also includes working in accordance

with the operating and installation instructions and

complying with the maintenance requirements.

The threshold values specified in the technical

data must not be exceeded.

1.10  Warranty

For warranty claims to be considered, it is essential

that the ordering party or its representative com-

plete and return the "certificate of warranty" to

REMKO GmbH & Co. KG at the time when the

units are purchased and commissioned.

The warranty conditions are detailed in the "Gen-

eral business and delivery conditions". Further-

more, only the parties to a contract can conclude

special agreements beyond these conditions. In

this case, contact your contractual partner in the

first instance.
