* Water tank & Floor heating installation
1. Use the pump (1) with sufficient capacity to assure loss of overall water pressure and to supply
water to the Hydro Kit.
2. Install the shut-off valve (2) on both sides of the pump to clean and repair the pump.
3. Install the flexible joint (3) to prevent noise and vibration transferred from the pump.
4. Install the pressure gauge (4) to monitor the water pressure from water tank. (Option)
5. Install the expansion tank (5) to accommodate the water contracted or expanded from the temper-
ature difference and to supply the water.
6. After the installation of water pipe system is completed, open the water supply valve (6) and sup-
ply the water.
7. When installing the water tank, insert the water tank temperature sensor (7) to measure the tem-
perature of the water inside the tank.
- For the water tank temperature sensor, use the sensor supplied on the product.
- When heating the floor, measure the temperature by using the remote controller or remote tem-
perature sensor (Separately sold).
8. Use the water tank (9) with the heat exchange coil (8) installed so that the heat can be exchanged
sufficiently inside the tank.
