use of other parts may invalidate liability for

resulting consequences.

1.9 Intended use

The heater for anti-freeze protection is used to

control the temperature of the interior space of the

hydraulic module. This ensures that in the event of

a fault, the last step in the freezing of the medium

and thus defects due to frost can be prevented. A

temperature of >+3 °C is established through recir-

culated air operation. It is essential that a separate

UPS is used for the power supply.

Any different or additional use is a non-intended

use. The manufacturer/supplier assumes no lia-

bility for damages arising from 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.

1.11 Transportation and

packaging

The units are shipped in sturdy transport pack-

aging or within the heat pump housing. Immedi-

ately check the units on delivery and make a note

of any damage or missing parts on the delivery

note. Inform the forwarding agent and contractual

partner. Claims under guarantee made at a later

date will not be accepted.

WARNING!

1.12 Environmental protection and

recycling

Disposing of packaging

All products are packed for transport in environ-

mentally friendly materials. Make a valuable contri-

bution to reducing waste and sustaining raw mate-

rials. Only dispose of packaging at approved

collection points.

Disposing of the units and their components

For the manufacture of the units and components,

only recyclable materials have been used. Help

protect the environment by ensuring that the units

or components (for example batteries) are not dis-

posed of in household waste, but only in accord-

ance with local regulations and in an environmen-

tally safe manner, e.g. using authorised disposal

and recycling specialists or council collection

points.
