SHUTDOWN.
Do not tip the compressor more than 5 degrees from horizontal to
avoid flowing oil into unwanted places.
AVOID CONTAMINATION. When checking the compressor for shipping
damage, do not connect gas lines and cold head. The components may become
contaminated with compressor oil.
1. Upon receipt, inspect the shipping container and the compressor for damage.
1.1. If there is any evidence of external damage to the container, be sure the carrier’s driver
sees the damage. Note it on the shipping documents and have the driver acknowledge
it by his initials on the delivery receipt.
1.2. Remove the compressor from its shipping container and inspect for damage. If there
was external damage to the compressor, remove its covers and check for internal
damage. Notify the carrier immediately and take photographs of the damage to
document your claim to the carrier. Keep the damaged shipping container.
NOTE
Retain the shipping containers, if reusable, for returning the components to the
factory if reconditioning is required. If internal damage is suspected, retain the
shipping container for proof to the carrier.
2. Inspect for Proper Charge Pressure
2.1 The Charge Pressure of the Compressor Unit can be checked from the outside of the
shipping container without removing the packaging.
