REMKO RKW 1000 – 9800 INOX Stainless Steel Chiller Operation ...

Changing the Target Values (Parameters)

A parameter is a modifiable value that can be set by the

operator/installer to adjust the chiller to the specific conditions

and guarantee optimum operation.

For example, the return temperature, the frost protection

alarm temperature and the new switch-on differential

can be changed after the target temperature has

been reached.

Access rights for system operators and qualified maintenance

and service personnel is divided into two parameter

levels. The operator can only change basic parameters

on the first level and the service personnel can

change system-specific parameters on the second level

after entering a password.

A technical data sheet which explains the second parameter

level can be requested separately by a qualified

company from REMKO GmbH &Co. KG.

First Parameter Level for the System Operator

The first parameter level is accessed by pressing the

ON/OFF/RESET button. The current return temperature

is displayed.

After pressing the MENU button, the programmed value

of Parameter 02 (right-hand code display) appears in

the left-hand display. The right-hand parameter display

begins to blink when the SET

button is pressed. This mode displays the options for

changing the parameters to the programmer.

If one of the arrow keys is now pressed, the parameter

jumps to the next higher or lower parameter.

Once the correct value has been reached for the parameter,

the value display begins to blink after the SET

button has been pressed. The displayed value can now

also be changed using the arrow keys. The programming

level can be exited by pressing the SET button a

third time. The settings are saved and the return temperature

is displayed again.

Maintenance and Service

The unit almost never requires maintenance. Regular

care and the observation of a number of basic rules will

ensure the unit’s long service life and reliable operation.

◊ We recommend concluding a maintenance agreement

with a company who specialises in this type of

work. This will guarantee that the system operates

safely at all times!

◊ Keep the unit free of dirt, plants and other deposits

and only clean the units with a damp cloth.

Do not expose the units to a direct stream water.

◊ Do not use an abrasive cleaning agent or one that

contains solvent; if the units are extremely dirty, only

use suitable cleaning materials.

◊ Before taking the unit out of operation for a longer

period of time, clean the plate fins of the unit while

the ventilator is in operation and cover the unit with a

plastic sheet to prevent dirt from entering the unit.

◊ For systems with brine, check the ratio of water to

Antifreeze N or Antifreeze L before taking the unit out

of operation in winter to protect the system from

frost.

◊ We recommend having the unit checked at regular

intervals (once or twice a year) to ensure that it is

functioning properly and there are no leaks.
