Installation procedures should be performed in the
sequence that they appear in this manual. Do not destroy or
remove the manual from the unit. The manual should
remain weather-protected with the unit until all installation
procedures are complete.
Note: It is not the intention of this manual to cover all possible
variations in systems that may occur or to provide
comprehensive information concerning every possible
contingency that may be encountered during an installation. If
additional information is required or if specific problems arise
that are not fully discussed 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 Company assumes no liability for installations 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 procedures 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 procedures.
Unit Inspection
Inspect material carefully for any shipping 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 characteristics
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 following 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 damage before it is stored
and as soon as possible after delivery. Concealed damage
must be reported within 15 days. If concealed damage is
discovered, stop unpacking the shipment. Do not remove
damaged material from the receiving location. Take photos
of the damage if possible. The owner must provide reason-
able evidence that the damage did not occur after delivery.
[ ] Notify the carrier’s terminal of damage 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 TTA units are shipped with a holding charge of nitrogen
in each circuit. Remove the compressor access panel(s)
shown in Figure 1 through Figure 7. Locate the liquid line or
suction line service valve for each circuit. Install gauges to
determine if the circuits are still pressurized. If not, the
charge has escaped. Repair as required to obtain a leak-free
circuit.
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
distributed. Approximate unit weights are given in Table 4.

ON-SIGHT LIFTING
EQUIPMENT MUST BE CAPABLE OF LIFTING THE
UNIT WEIGHT WITH AN ADEQUATE SAFETY FACTOR.
THE USE OF UNDER-CAPACITY LIFTING DEVICES
MAY RESULT IN SEVERE PERSONAL INJURY OR
DEATH AND CAN SERIOUSLY DAMAGE THE UNIT
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: Use spreader bars to prevent lifting straps
from damaging the unit. Install bars between lifting
straps. This will prevent the straps from crushing the
unit cabinet or damaging the unit finish.
