HVAC Chiller Installation Procedure

 HVAC Chiller Installation Procedure

In this post we can learn about how to do the chiller installation in hvac system.  The following documents are needed to install the chillers in hvac system

  1. Typical Installation Detail Drawing.
  2. Working drawings showing DCS Plant room.
  3. Chiller supplier’s installation manual..

We should prepare the following tools need to install the chillers. 

They are 

  1. Measuring Tape.
  2. Marking Pad / Ink.
  3. General Hand Tools.
  4. Impact Drill.

  6. Water Level.
  7. Winch.
  8. Hydraulic Jack.
  9. Protective Sheet

The following preparation work should be done

Check Chiller for the correct model and type when it arrives on site.

Examine Chiller's plinth size, location, and height in relation to the Plinth Layout and working drawings.

Check and double-check the type, size, and quantity of vibration isolators.

Check the clearance of the chiller delivery route from the ground level to the plant room.

Apply for clearance for a mobile crane and a low bay trailer at least one day before the actual lifting activities.

Safety is the one main thing in every work has to be done. we should keep eyes on safety work during chiller installation.

If necessary, barricade the affected work areas for safety.

Wear personal protective equipment (PPE) for your own safety and protection.

Before using mobile crane gear equipment, confirm the documentation.

Only qualified lifting supervisors, signallers, and riggers may command and control lifting operations.
