Note: It is not the intention of this manual to cover all possible varia- tions in systems that may occur or to provide comprehensive information concerning every possible contin- gency that may be encountered dur- ing an installation. If additional information is required or if specific problems arise that are not fully dis- cussed in this manual, contact your local Sales office.
Note: “Warnings” and “Cautions” appear at appropriate
places in this manual. Your personal safety and the proper
operation of this machine require that you follow them carefully. The Com- pany assumes no liability for installa- tions or servicing performed by unqualified personnel.
Installation Checklist
An “Installation Checklist” is provided at the end of the installation section of this manual. Use the checklist to verify that all necessary installation proce- dures have been completed. Do not use the checklist as a substitute for reading the information contained in the manual. Read the entire manual before beginning installation proce- dures.
Unit Inspection
Inspect material carefully for any ship- ping damage. If damaged, it must be reported to, and claims made against the transportation company. Compare the information that
appears on the unit nameplate with ordering and submittal
data to insure the proper unit was shipped. Available power supply must
be compatible with electrical charac- teristics specified on component nameplates. Replace damaged parts with authorized parts only.
Inspection Checklist
To protect against loss due to damage incurred in transit, complete the fol- lowing checklist upon receipt of the unit.
[ ] Inspect individual pieces of the shipment before accepting the unit. Check for obvious damage to the unit or packing material.
[ ] Inspect the unit for concealed dam- age before it is stored and as soon as possible after delivery. Con- cealed damage must be reported within 15 days. If concealed dam- age is discovered, stop unpacking the shipment. Do not remove dam- aged material from the receiving location. Take photos of the dam- age if possible. The owner must provide reasonable evidence that the damage did not occur after delivery.
[ ] Notify the carrier’s terminal of dam- age immediately by phone and by mail. Request an immediate joint inspection of the damage by the carrier and the consignee.
[ ] Notify the sales representative and arrange for repair. Do not repair the unit until the damage is inspected by the carrier’s representative.
Initial Leak Test
All CTA units are shipped with a hold- ing charge of nitrogen in each circuit. Remove the service access panel(s) shown in Figures 1 to 4. Locate the discharge or liquid line gauge ports for each circuit. Install gauges to determine if the circuits are still pres- surized. If not, the charge has escaped. Repair as required to obtain a
Lifting Recommendations
Before preparing the unit for lifting, estimate the approximate center of gravity for lifting safety. Because of placement of internal components, the unit weight may be unevenly dis- tributed. Approximate unit weights are given in Table 2.

WARNING
Heavy Objects!
Do not use cables (chains or slings) except as shown. Each of the cables (chains or slings) used to lift the unit must be capable of supporting the entire weight of the unit. Lifting cables (chains or slings) may not be of the same length. Adjust as necessary for even unit lift. Other lifting arrangements may cause equip- ment or
The crated unit can be moved using a forklift of suitable capacity. For lifting the unit, attach lifting straps or slings securely to the lifting holes at each corner. Use spreader bars to protect the unit casing from damage. Test lift the unit to determine proper balance and stability.
CAUTION
Equipment Damage!
Use spreader bars to prevent lift- ing straps from damaging the unit. Install bars between lifting straps. Failure to properly lift unit may result in crushing unit cabi- net or damaging unit finish.
