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 reasonable
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.
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 2.

WARNING
Improper Unit Lift!
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 death or serious injury or
possible equipment or property-only
damage.
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.
