Aqua Medic Titan 4000 Mode D'emploi page 4

With the purchase of this cooling unit, you have selected a top quality product. It has been specifically designed
for the cooling of closed water cycles like fresh and salt water aquaria.
The Titan coolers are supplied with heat exchangers made from salt water proof Titanium steel. These heat
exchangers are corrosion resistant and free of contaminations. The cooling units can be used in fresh and salt
water as well as in various chemicals.
The coolers have a one-phase cooling system containing the cooling medium R 134a (FCKW-free). They work
with capillary injection as control system.
1. Product description
The Aqua Medic cooling units Titan 4000 are supplied with:
- a temperature computer with digital display
- connections for water in- and outlet
- a solid cover made of plastic and metal
2. Set-up and installation
1. The cooling unit must be set up at a well-aerated place. The complete heat taken out of the water by
the unit and the waste heat of the unit itself are emitted at the unit to the surrounding air. A build-up of heat
directly at the cooling unit leads to a heavily reduced cooling power output. Therefore, a sufficient ventilation
is essential.
The environmental temperature should not exceed 35 °C.
2. The cooling unit has to be connected at the connecting pieces to a closed water cycle. This is done either
through a fixed connection of plastic tubes or through hoses (connection pieces are available as optional
It is recommended to place the unit below the water surface (max. 150
extras).
cm resp. 0.15 bar). The cooling unit may only be operated with a maximum
pressure of 0.15 bar, otherwise, it will leak which is not repairable. This must
be strictly observed when setting up and selecting the pump.
3. Switch the water flow on. It is important that the water flows continuously through the cooler. Because the
temperature-sensor is placed within the unit, the heat exchanger cannot freeze in case of a failure of water
supply. The minimum flow rates are: 3,000 – 6,000 l/h.
4. Before starting, the cooler should stand up straight for at least 1 hour. Connect it to 230 V power source and
switch the unit on (plug in the mains and switch on). Now, the actual water temperature is shown in the
display. Because the thermo sensor is placed in the water inlet, always a temperature which corresponds to
the temperature in the tank is shown.
3. Temperature control
The cooling unit of the Titan series is supplied with a digital temperature controller.
Programming: The display shows the actual temperature of the water.
Check the set point: Press the „SET" button (shortly). Now, the set point is shown in the display and a LED
(up, left) flashes. After some seconds, the unit switches back to the actual temperature.
Adjustment of the set point: Press the „SET"- button for approx. 5 sec. Now, the set value is "LbS" displayed.
Press "SET" again. The set value can now be changed in steps of 1 °C, using the ▲ and ▼ buttons. By pressing
the "SET" button again, the set point is saved. Don't change other values of the menu (dFt = 3, dSt = -4.0, CHd
= C1). These values can be reached by pressing the arrow keys after the release of LbS and then confirm with
set. Adjust the set point again with arrow keys and confirm again with set.
The status of the cooler (compressor on or off) is indicated in the small LED in the display (between the second
and third digit of the display).
