6-4. Precautions of Installation of the Refrigerant Fill Product

Make sure to pay special attention to the following for the machine that is delivered with the refrigerant filled and
comply with the following precautions about refrigerant leakage accidents when delivering or installing.
LG Electronics does not take any responsibility for problems due to not complying with the precautions.
6-4-1. Checklists before Delivery and Installation
1) Check if ventilation facilities are prepared in the machine room in which the Centrifugal Chiller will be installed.
No ventilation in case of the refrigerant leakage may cause suffocation.
6-4-2. Precautions during Bring-in and Installation
1) Move the Centrifugal Chiller after balancing enough. Make sure to pay a meticulous attention when moving as an
impact on the Centrifugal Chiller or tilted Chiller may cause damage to the Centrifugal Chiller due to the leakage
of the refrigerant.
2) Make sure that the wire does not interfere with the valve and piping, etc. up when lifting the Centrifugal Chiller
up.
3) Make sure that the piping or valve does not collide with the pillar or obstacles when lifting or bring down the
Centrifugal Chiller.
4) Refrigerant filled and oil weights are added to the Centrifugal Chiller weight when bring in it. Make sure to con-
sider additional weight when bring in the Centrifugal Chiller.

6-4-3. Precautions after Installation

1) Make sure to avoid damage of the valve and piping, etc. of the Centrifugal Chiller when implementing works
such as connecting water piping, safety valve discharge piping and cold insulation.
2) Make sure that high temperature water does not flow into the Chiller after water piping construction.
3) Consult with service staffs for a long-term storage.
4) Always run the ventilation facilities. Leakage of the refrigerant may cause oxygen deficient accidents.
6-4-4. Actions for the Refrigerant Leakage
1) Close the joint and valve and block the leakage when the leakage part is found and can be handled without a dan-
ger.
2) Move the Centrifugal Chiller to an open and danger-free place to discharge when the leakage does not stop and
the Centrifugal Chiller can be moved.
Open the installation room for enough ventilation if the Centrifugal Chiller cannot be moved.
3) Evacuate people in the surrounding area and ban access of the people by blocking with a rope around the place
of leakage if the leakage volume is large. Make sure to wear oxygen breathing apparatuses.
4) Clean eyes with flowing clean water for more than 15 minutes and see a doctor immediately if the refrigerant
contacted the eyes.
5) Immediately take off wet clothes, shoes and socks as there is a danger of frostbite when the refrigerant con-
tacted the skin. See a doctor immediately after first-aids.
6) Go to a place with fresh air immediately and warm the body with a blanket and see a doctor immediately after
first-aids when inhaled highly concentrated gas.
