Aqua-Mex
Installation, general
Aqua-Mex and Aqua-Mex FE can be installed together with a heat pump, solar panels or other heatsource, either with built-in
temperature control or solely as a heat exchanger.
Pipe installation shall be performed first and must be completed before work starts on the electrical installation by an
authorized electrician. The primary circuit (hot water) should be connected by a plumber.
• The heat exchanger should be fitted within 10 metres of the pool and within 5 metres of the heat source, in order to minimize
pressure drop and heat loss.
• The pipes leading to and from the heat source should be insulated.
• The heater is equipped with 2" couplings (diameter 63 mm) for bonding.
• We recommend to fit an air bleed valve at the highest point in the primary circuit. After completion of installation, the primary
circuit should be bled (see the section entitled "Maintenance").
• The circulation pump's motor, openings and condensation holes must be left free from any supplementary insulation material.
• If there is a risk of sub-zero temperatures, and also if the pool is closed for longer than one month, the heat exchanger should
be drained of all water.
Installation, pipe-work
For fitting above the pool's water surface, the pipes should be installed in a loop to prevent the heat exchanger from draining itself.
Injection of chlorine, acid or other substances shall take place after the heat exchanger to avoid the risk of corrosion.
The Aqua-Mex FE shall be fitted horizontally on a wall or similar surface, see the diagram below.

Fully equipped Aqua-Mex FE:
The circulation pump may not be connected until all welding or
soldering work has been completed and the pipes have been
flushed clean.
1. Check the direction of flow prior to installation:
The secondary circuit's flow (the pool water) is marked on the heat exchanger's
flow switch housing. NB! The primary and secondary circuits' flow shall be in opposite
directions for maximum effect, see the diagram below and the section entitled
"Alternative direction of flow".
2. Seal the thread on the non-return valve using thread sealing tape or similar.
3. Fit the two wall mounting brackets. Each bracket has two holes Ø6, c/c 91 mm.
Between the brackets the c/c distance is 610 mm.
4. Place the heat exchanger in the brackets.
5. Connect the secondary circuit (the pool water).
6. Screw the brackets together.
7. Check that the connections do not leak.
After this, the pool's circulation system can be started up.
8. Connect the primary circuit.
NB: The heat exchanger's existing nipples (A) on the primary circuit must not be removed. .
9. Check that the connections do not leak.
10. Bleed the primary circuit.
11. The electrician can now connect the circulation pump, see the section entitled "Electrical installation".
