General Information
Foreword
These instructions do not attempt to cover all variations in
systems, nor to provide for every possible contingency to be
met in connection with installation. Should further information
be desired or should particular problems arise which are not
sufficiently covered for the purchaser’s purpose, the matter
should be referred to the manufacturer.
Reception
On arrival, inspect the unit before signing the delivery note.
Specify any damage on the delivery note, and send
aregistered letterofprotestto thelastcarrierof thegoodswithin
72 hours of delivery. Notify the local Trane Sales Office at the
sametime.The unit shouldbe totallyinspected within 15days
of delivery. If any concealed damage is discovered, stop
unpacking the shipment. Take photos of the damage material,
if possible. Notify the carrier immediately by phone and
registeredmail. Notifythe localTraneSalesOffice.Concealed
damage must be report within 15 days of delivery. Check the
unit nameplated to confirm that the proper unit was shipped.
Available power supply must be compatible with electrical
characteristics specified on component nameplates.
General Information
This manual covers the Installation, Operation, and Mainte-
nance of the SRUB080, SRUB 110 and SRUB 130 single
circuit, and the SRUB 160, SRUB 190, SRUB 220 and SRUB
250 dual circuit. These new package air-cooled self contain
models are completely redesigned for a scroll compressor,
improved application flexibility, servicing and maintenance
accessibility, and an improved accessory line. They are of the
vertical or horizontal discharge with the vertical standard.
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 manufacturer assumes no liability for installation
or servicing performed by unqualified personal.
Special Note on Refrigeration Emissions
World environmental scientists have concluded, based on
the best currently available evidence, that ozone in our
upperatmosphereis beingreduced due torelease ofCFC
fully halogenated compounds.
The Trane Company urges all HVAC servicers working on
Trane equipment, or any manufacturer’s products, make
everyeffortto eliminate, ifpossible, or vigorously reduce
the emission of C F C, H C F C, and H F C refrigerants to
the atmosphere resulting from installation, operation,
routine maintenance, or major service on this equipment.
Always act in a responsible manner to conserve refrigerants
for continued use even when acceptable alternatives are
available.
Unit Inspection
Inspect material carefully for any shipping damage. If
damaged,it must bereported to,and claimsmade againstthe
transportationcompany.Compare theinformationthat 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.
WARNING : Open and lock unit disconnect to
prevent injury or death from electric shock or contact
with moving parts before attempting any installation
or maintenance.

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.
Warning : 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.

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 consealed 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.

Installation Considerations
1. The floor or foundation for the unit must be level, solid and of sufficient strength to
support the unit the floor before positioning the air conditioner.
2. Allow minimum recommended clearances for maintenance and routine service.
Refer to “Service Data”. See in figure 1
3. Availablepower supplymust agreewith electricaldata oncomponent nameplate.
4. If external accessories are installed on the unit, additional clearance must be
provided.
5. All duct word should be properly insulated to prevent condensation and heat loss.
6. If adding external accessories to the unit, additional clearances must be
considered for the overall space needed.
7. For installation of accessories available for this unit follow the instructions packed
with each accessory.
