6.8. Check the Leakage
Check all the joints with the leak detector or soap water.
6.9. Thermal insulation
Use appropriate thermal insulation for pipe insulation. Use thicker insulation
when installing in hot or humid conditions.
1. Use the thermal insulation with properties that can withstand 120 C.
7. WIRING
7.1. Electrical wiring
CAUTION
1. Ensure all power cable installation works are carried out by a qualified
electrician.
2. All equipment must be grounded and have a local isolation point.
3. Ensure when installing power cables they are installed in different
containment to communication cables.
4. If you have to extend the cable, make sure you use connective blocks or
connecting terminals.
5. Before turning on the power, ensure all terminals are connected securely.
