Operation Manual
Congratulations for your new Polar Chiller. It is a quality product and has been specially
designed for aquarium and pond use. It has been developed and tested by specialists.
The flow through chiller Polar are supplied with sea water resistant heat exchanges made
of Titanium.
The heat exchangers are absolutely corrosion proof and contamination free. The chillers
can be used for freshwater and marine aquariums and with a broad number of chemicals.
The chiller have a one stage cooling system with R 134a as cooling oil (FCKW free) They
work with capillary injection.

1. Delivery
The Theiling cooling units of the Polar series are supplied with:
- a temperature computer with digital display
- Connections for water in and outlet.
- On/Off switch with fuse.
- Exchangeable air filter
- Strong housing made of metal and plastic
The units are ready to use
2. Installation
2.1 The cooling unit must be installed in a well aerated place. The
complete heat that the unit extracts from the water is blown into the air as
well as the excess heat of the unit itself. A heat build-up at the chiller will
result in a decrease of the cooling capacity and in the long term destroy the
unit. Good ventilation is absolutely necessary. The hot air must flow open from
the back side of the unit. The unit may only be placed inside of an aquarium
cabinet, if sufficient aeration grids guarantee the exchange of the air.

2.2 Advise of the setup:
-1. Do not place the unit outdoors
-2. Do not place the nit in direct sunlight.
-3. Place the unit on a horizontal area
-4. Keep sufficient distance from a wall.
-5. Do not cover the cooler, when it is working. Do not shake it.
-6. The cooler has no integrated circulation pump. We recommend to use the River 2700
pump for the water supply.
-Do not tilt the cooler. Wait minimum 1 hour after the setup of the cooler before you
start it.
Setup of the chiller
-1. besides a filter sump. The pump circulates the water between sump and chiller
-2. besides the aquarium, but below the water level.
-3. Integrated into the filter cycle, but pressure less at the outlet.
The ambient temperature may not exceed 35°C.
3. START
1. Connect the chiller to the water cycle.
2. Switch on the water flow. Make sure, that water flows through the chiller –
always. The temperature sensor is located inside of the heat exchanger. This
prevents freezing and damage of the heat exchanger, in case the water flow is
interrupted.
3. Control all pipes and connections to be water tight. If there is a leakage, tighten
the unions. Control the water flow and make sure the pipes are not clogged.
4. The chiller must stand upright minimum for one hour before starting. Connect it to
the mains (230V/50 Hz~). Switch the unit on. The actual water temperature is
displayed. The temperature sensor is near the water inlet. The temperature displayed
is the real temperature in the aquarium
Attention: Operate the Chiller pressure less
Set up maximum 150 cm below the water level in the aquarium.

4. Temperature Display
The Theiling Polar Cooling units are supplied with a digital temperature
controller.
Programming: During operation, the display shows the actual aquarium water
temperature.
-Display of the set value
Press the „Set“ button. The programmed set value and the actual aquarium water
temperature are displayed alternating. The temperature indicator (1) is switched off,
if the actual temperature is displayed. It flashes when the set value is displayed.
-Set point adjusting
Press the „Set „ button for longer than 3 seconds to enter the program mode. Now
the set value is displayed. By pressing the and –buttons the set value can be
adjusted in the range from 3°C to 32°C. If you have adjusted the set value, you can
save it by pressing the “SET “button. Now the aquarium temperature is displayed and
the chiller is working.
-Switch on Protection.
To prevent a frequent on and off switching of the chiller, it will start again only after a
break of minimum 3 minutes. If switched on for the first time, it will start after 1
minute.
.
- Temperature control
If the cooler was switched off for minimum 3 minutes and the water temperature
rises for 1°C above the adjusted set value, the unit is switched on automatically and
the water is cooled. As soon as the water temperature reaches the set value, the
cooler is switched off.
The „working“ LED (7) is switched on when the cooler is working and is switched off,
when the set temperature is reached and the cooler is switched off. If this LED
flashes, the cooler is in the 3 minute wait phase (switch on protection).
-Automatic switch Off
The cooler is switched off automatically, when there are problems with the
temperature sensor. The display will then show: “ P1“ or „P2“

6. Maintenance
The cooling unit needs the same maintenance like conventional cooling units (Freezers).
All Maintenance and repair works have to be done by authorised workers or send the unit
back to the factory.
Clean the air cooled condenser regularly. Disconnect the unit from the mains. Open
the Housing carefully with a Philips screw driver. Clean the lamellae of the condenser
carefully with a vacuum cleaner. Without regular cleaning, the fan and the compressor
may be damaged
We recommend flushing the heat exchanger one per year with tap water to remove
sludge residues.

difference is too big.
Change the unit to a bigger
one or reduce the water
volume.
The cooler is noisy or
