Product description
Maxi-Flo Titan is a type of tubular heat exchanger with spiral-shaped tubes for the optimal heat transfer. It is made of titanium
to be used in the systems with a high corrosion risk.
Titanium is advantageously used in the pool systems where salt water or chlorinator is used.
Maxi-Flo Titan must be connected to a heat source, such as boiler, heat pump or storage tank for the solar energy collecting
facility.
Maxi-Flo Titan is available in two versions: 75kW and 200kW.

Installation
Place the heat exchanger as in the drawing.
When installed above the pool water, the pipes should be laid in the loop, so that the heat exchanger cannot get self-drained.
Dosing of chlorine, acid or similar substances must always be done AFTER the heat exchanger.
If the pool circulation is terminated or suspended, the circulation pump on the primary side shall be switched off.
At the risk of freezing and if the pool is closed for the winter for longer than 1 month, the heat exchanger must be drained of
all water.
Mounting
Measure and mark where the heat exchanger is to be located.
Wall xture should be mounted on a solid, at surface/wall.
Modell MFT260
1. Mount the supplied wall brackets onto the wall.
2. Insert a strap into every wall mount.
3. Hold the heat exchanger and tighten the straps around it.
Model MFT680
1. Insert the supplied wall brackets as is shown in Fig.2.
Mount the top bracket with three screws in the round holes.
Mount the bottom bracket rst into the hole with a screwdriver.
2. Hang up the heat exchanger.
Slide up the bottom bracket until the heat exchanger lies against the xture.
Mark at least three of the round mounting holes and put down the heat exchanger.
Fasten the lower xture (at least three of the round holes).
3. Hang up the heat exchanger.
4. Mount the self-adhesive gaskets for heat exchanger tube spigots.
5. Place the detachable ange onto the heat exchanger tube
spigot, see Fig. 3.
Drag the screws through the anges and make sure
that the screws on the left side of the heat exchanger
go through the hole in the wall bracket (A).
6. Tighten the screws (with a washer and nut)
with a torque of 30 Nm.
Flange sleeve (2x)
