Platinum™Oxygen 0 Part No 1118396
SHIPPING AND HANDLING
Before you install and operate the concentrator, please refer to the Platinum Owner s
Manual (1118389).
The concentrator should ALWAYS be kept in the upright position to prevent cabinet
damage while being transported. The shipping container has been designed to assure
maximum protection of the concentrator.
If the concentrator is to be reshipped by common carrier, additional cartons are available
from Invacare.
The air compressor suspension system has been engineered to withstand severe motion
and orientation.
Unpacking
1. Check for any obvious damage to the carton or its contents. If damage is evident,
notify the carrier, or your local dealer.
2. Remove all loose packing from the carton.
3. Carefully remove all the components from the carton.
NOTE: Unless the oxygen concentrator is to be used IMMEDIATELY, retain containers and
packing materials for storage until use of the concentrator is required.
Inspection
1. Inspect/examine exterior of the oxygen concentrator for nicks, dents, scratches or
other damages. Inspect all components.
Storage
1. Store the repackaged oxygen concentrator in a dry area.
2. DO NOT place other objects on top of
the repackaged concentrator.
