Insulation
1. The insulation design and materials should be complying with local and national codes and regulations.
2. Chilled water pipes and all parts on the pipes should be insulated.
The flow resistance of the connecting valve/hydraulic kit assembly is obtained from the following formula:

Pipe Connection
1. Using suitable fittings as water pipe connections with reference to the outline and dimensions.
2. The water inlet is on the bottom while outlet on top.
3. The connection must be concealed with rubberized fabric to avoid leakage.
4. Tightening torque should not be too high when connecting water pipes, in order to avoid brass deformation
or water-leakage by torsion split.
Wiring
1. Refer to the wiring diagram of the appropriate controller.
2. For connection with the DAIKIN controller, position the water temperature probe into the appropriate
position. Refer to the dedicated controller installation and operation manual.
