Operation
(only for Aqua-Mex FE)
In order for the heater to work, the pool water must circulate.

In the event of a power failure, the set temperature will be retained in memory.
In order to achieve the highest power output, the circulation pump is set at its highest power
setting.
In order to minimize energy consumption at times of lower heating requirement, for instance for
minimal heat maintenance, follow these recommendations: Aqua-Mex FE 40kW - setting I
Aqua-Mex FE 70kW - setting II
Operation
If pool circulation ceases or is switched off, the circulation pump on the primary circuit must
also be switched off.
If there is a risk of sub-zero temperatures or if the pool is shut for the winter or for longer than
one month, the heat exchanger must be drained of all water.
On the underside of the heat exchanger there are two drainage plugs for the secondary water circuit.
Note that during storage, the pump for the Aqua-Mex FE should not be exposed to temperatures beyond -10ºC to +50 ºC.
If there is any air in the pump housing, the pump will not function optimally.

Follow the recommendations below for pool water:
Chlorine content:
max 3 mg/l (ppm)
pH rating:
7.2-7.8
Alkalinity:
60-120 mg/l (ppm)
Chloride (salt) content: max 150 mg/l (0.015%) g stainless acid-proof steel version
above 150 mg/l (0.015%) g for the titanium version
Calcium hardness:
200-1000 mg/l (ppm)
Bleeding of the system via the valve in the primary circuit.
1. Make sure the circulation pump is operating (power setting III).
2. Open the bleed valve slowly (watch out for hot water).
Bleeding of the circulation pump
(only for Aqua-Mex FE)
1. Switch off the pump. Do not touch it – risk of burn injuries.
2. Shut off the pipe in the pressure circuit.
3. Slowly open the air screw with a screwdriver (watch out for hot water).

4. Carefully press back the pump shaft several times with the screwdriver.
5. Protect all electrical components from any water that emerges.
6. Start the pump. WARNING – owing to operating pressure the pump
may be blocked when the air screw is open.
7. After 15-30 seconds, tighten the air screw.
8. Open the shut-off valve in the pressure circuit.
