4. PRODUCT TAKEOVER
4-1. Delivery List and Status Inspection
• The Centrifugal Chiller is shipped assembled or partially and filled with the refrigerant or nitrogen depending on the
status of the site. For partial delivery, it requires an agreement from the customer in advance.
1) Assembled or partial delivery
All parts are delivered assembled in case of the assembled product, and parts are delivered through 2 or 3 times
of delivery depending on the site conditions in case of the partial delivery.
2) Refrigerant-filled delivery or nitrogen-filled delivery
In case of the assembled product, the refrigerant or nitrogen is filled for delivery based on requests by the cus-
tomer.
In case of filling the refrigerant, the filling refrigerant volume that the Chiller needs is sealed, and in case of the
refrigerant, be cautious of the high pressure as a saturated refrigerant pressure is determined depending on the
outside temperature. (the oil is delivered separately and filled during the test run.)
The product is shipped from the factory at the nitrogen pressure of 0.5kg/cm2. If the pressure is “0”, make sure
to record and inspect leakage parts as there is a possibility of a leakage.
4-2. Product Check
1) Check if the product shipment list and takeover list matches.
2) Check terms on the product nameplate with the project information.
Refer to Section 2-4 for terms on the nameplate.
3) Check the exteriorof the product and check if there is any damage and leakage.
Check for the safety of the damaged parts (refrigerant leakage, etc.) when detected and contact the service center
to take corrective measures by our engineers after taking pictures of damaged parts for its seriousness.
4-3. Product Protection
• When taking over the product, inspect and record the following to protect the product.
1) The product is shipped with the refrigerant or nitrogen filled to prevent corrosion due to inflow of outside mois-
tures.
Make sure to avoid arbitrary control or opening of the valves of connection parts attached on the product.
The refrigerant leakage may cause damage of human life when filling the refrigerant.
If the water box is sealed by clamping with blank flanges, open it after purging the nitrogen in advance when
opening the flanges as it is filled with nitrogen at the pressure of 0.5kg/cm2.
Caution) Do not open the service valve, etc. in any case when the nitrogen or refrigerant is filled.
Product damage problem may be caused if the nitrogen is lost by opening the valve.
2) Inspect and record leakages by damage or loose bolts by inspecting the exterior and piping when taking over the
product.
3) The product is delivered with no oil filled to prevent oil from turning into steam due to the refrigerant dissolution
when delivering or storing in case the product is shipped with the refrigerant filled.
Contact our engineers if the oil level cannot be seen through the sight glass.
4) Raise contents of the problem to the deliverer if there is product damage or part abnormality during inspection
and call a person in charge at LG Electronics. Damaged products should not be installed without an approval of
LG Electronics
!
CAUTION
Make sure to check if there is any damage occurred in the process of delivery by inspecting the status of the
Chiller before unloading the product when the product delivery vehicles arrives at the site.
