Security Advice
Please ensure the power supply and electrical outlet are securely connected and that the
grounding wire is connected.
The average operating current of the chiller is small, but the instantaneous operating current could be
up to 10 amps.
Please make sure there is a stable and normal voltage for the working chiller!
The standard operating voltage for the chiller is 220V.
Mismatched power frequency can cause damage to the chiller!
Be sure you can run a machine with 50 Hz.
To protect the pump, it is strongly advised that you do not run the chiller without having
water in the water reservoir!
The machine is packaged without water in the tank, so make sure the tank has enough water inside
before starting it otherwise the pump can be damaged.When the water level is below the green
(NORMAL) range of the water level gauge, the cooling capacity of our chiller will go down slightly,
hence please ensure the water level is within the green (NORMAL) range. Do not drain the water by
circulating the pump!
Please be sure that the air inlet and air outlet have good ventilation!
There must be at least 30 cm from obstructions to the air outlet in the back of the cooler and at Ieast
8 cm between obstructions and the side air inIet.
The fi lter screen must be regularly cleaned!
It‘s essential to unpick and clean the dust gauze, or a serious blockage could cause a breakdown to the
chiIIer.
Please pay attention to the effect of the condensate water!
When there is higher ambient humidity, and when the water temperature is lower than the ambient
temperature, condensation will appear on the surface of the water circulation pipes and the cooled
components. If this occurs, setting a higher water temperature or keeping connected pipes and cooled
parts warm is recommended.

Installation
Open the Fillport to fi ll in cooling water
Keep observing the water level gauge while adding water slowly. For the
cooling of carbon steel equipment, the water should be added an appropri-
ate amount of anti-corrosion additives.Working in cold areas, it‘s better to
use noncorrosive antifreeze fl uid.
Connect the water in- and outlet to your cooling circuit
Use two G1/4  ttings to connect the chiller with tubes.
Plug in power, turn on the power switch
Do not start up without water in the water reservoir!
1. The  rst time of operating may cause more bubbles in the tube leading
to a fl ow alarm. It will go back to normal after a few minutes of operating.
2. Check whether the system leaks immediatly!
3. If the water temperature is below the set value, it is normal the fans and
other components do not work.The temperature controller will automati-
cally control the working conditiond of the compressor,magnetic valve, fans
and other parts based on the set controlling parameters.
4. According to different conditions it may take more time to start the
compressor and other single components. So do not turn off and on again
frequently to avoid damaging parts.

Installation
Check the water level
The  rst startup of the new chiller empties the air in the water tubes,
leading to a small water level decline in the reservoir. Observe the water
level for a period of time and add adequate water if necessary.A rapid
water level drop may be a sign of system leakage.
Adjust parameters of the temperature controller
The machine uses an intelligent thermostat. Normally, users should not
need to adjust it. If it becomes necessary to do so, please refer to the
“Parameter adjustment” chapter.

Sicherheitshinweise
Stellen Sie sicher, dass Ihr Gerät sicher mit einer Stromquelle verbunden und der
Erdungsdraht angeschlossen ist.
Die durchschnittliche Stromstärke während des Betriebs ist zwar gering, kann aber Stromspitzen von
bis zu 10 Ampere erreichen.
Die angelegte Spannung sollte für den Wärmetauscher ausgelegt und stabil sein.
Die Standartspannung für das Gerät liegt bei 220V.
Nicht abgestimmte Frequenzen können das Gerät beschädigen!
Achten Sie darauf, ob Sie ein Gerät mit 50 Hz betreiben können.
Schalten Sie den Wärmetauscher niemals ohne Kühlfl üssigkeit an, dies kann die Pumpe
zerstören!
Das Gerät wird ohne Kühlfl üssigkeit im Tank ausgleifert. Füllen Sie also vor der Inbetriebnahme
genügend Wasser ein, sodass der Wasserstand im grünen Bereich liegt. Liegt der Wasserpegel darunter,
wird die Kühlstärke leicht abnehmen. Auch das Ablassen der Kühlfl üssigkeit ist bei laufender Pumpe
untersagt.
Stellen Sie sicher, dass die Lüfter genug Freiraum haben, um heiße Luft abzuführen und
Frischluft anzusaugen.
Lassen Sie hinter dem Gerät etwa 30cm Platz und zu den Seiten mindestens 8cm.
Reinigen Sie regelmäßig die Staubfi lter!
Je nach Arbeitsumfeld des Wärmetauschers, ist es notwendig den Filter häu g zu reinigen. Bei starker
Verschmutzung kann das Gerät sehr heiß werden und wird ich selbst abschalten.
Achten Sie auf entstehendes Kondenswasser!
Bei hoher Luftfeuchtigkeit und geringerer Wassertemperatur als Umgebungstemperatur entsteht
Kondenswasser an den Schläuchen und den zu kühlenden Bauteilen. Tritt dieser Fall ein, emp ehlt es
sich eine höhereWassertemperatur einzustellen oder die Schläuche und Bauteile künstlich zu
erwärmen.

Installation
Oberen Einlass öffnen und Kühlfl üssigkeit einfüllen
Behalten Sie dabei den Füllstand im Auge, der Pegel sollte im grünen
Bereich liegen. Für die Kühlung von Karbon-Stahl-Anlagen, sollte der
Kühlfl üssigkeit eine entsprechende Menge Anti-Korrosion Zusatz zugefügt
werden. Bei Einsatz in sehr kalten Gebieten ist es ratsam, nicht
korrodierendes Frostschutzmittel hinzuzufügen.
Kühlkreislauf mit demWasserein- und auslass des
Wärmetauschers verbinden
ZumVerschlauchen benötigen Sie 2 G1/4 Schlauchanschlüsse.
Mit Stromquelle verbinden und Gerät einschalten
Starten Sie das Gerät nicht ohne Kühlfl üssigkeit im Tank!
1. Bei der ersten Inbetriebnahme kann es vorkommen, dass sich vermehrt
Luftblasen bilden und der Durchfl ussalarm ausgelöst wird. Dieser löst sich
normalerweise nach wenigen Minuten wieder auf.
2. Prüfen Sie Ihren Kreislauf sofort auf Dichtigkeit.
3. Ist die Wassertemperatur unter den werkseitigen Einstellungsparame-
tern, ist es normal, dass Lüfter oder andere Komponenten nicht sofort
anlaufen. Die interne Temperaturkontrolle passt die Laufl eistung der Kom-
ponenten automatisch an.
4.Abhängig von den Umgebungszuständen, benötigen die Komponenten
unterschiedlich lang zum anlaufen. Häu ges An- und Ausschlaten, in kurzen
Abständen, kann zu Schäden an den Bauteilen führen.
