2. Delivery Check On
Arrival/Off-Loading and
Movement To The Site
2.1 Delivery Check
Check the delivery contents on arrival of
CLCH units in respect of completeness,
and note any damage which may have
occurred. In the event of any damage
being noted, a claim must be made by
return. Only by compliance with this
procedure is it possible to submit an
insurance claim. Any damage must be
noted on the delivery documentation,
dated and signed in the presence of the
delivery driver, and signalled by
registered letter to the last forwarder.
Claims in respect of obvious transport
damage or incompleteness of delivery
cannot be accepted in retrospect. In
the event of any complaints, please
notify the relevant Trane office
immediately, and in writing within 72
hours.
2.1.1. Identification
All Trane CLCH units are identified by the
sales number and manufacturer's works
order number given on the unit ID label.
Be sure to refer to the information given
on the unit identification label when
ordering replacement parts or requesting
service. The nameplate (see Figure 1) is
mounted on the fan-section access side,
and a manufacturer's plate (see Figure 2)
is fixed inside the fan section.
Figure 2 – Manufacturers Plate
2.2 Off Loading
A specific lifting method for offloading the
units is recommended as follows (see
Figure 3):
1) 52 mm-diameter lifting holes, or
certified lifting lugs, are provided on the
unit base frame.
2) ALL LIFTING POINTS in one axis of
the unit must be used when offloading
and moving the unit.
3) Slings and spreader bars are to be
provided by the rigger and attached to
ALL LIFTING POINTS.
4) The minimum rated lifting capacity
(vertical) of each sling and spreader
bar should be no less than the shipping
weight.
5) The unit must be lifted with care,
avoiding shock load by lifting the unit
slowly and evenly.
2.3 Moving To Position On
Site
Trane units are supplied in sections
modules, flat packed, or as a complete
unit, in accordance with the relevant
assembly drawings. Any necessary use
of force during unloading or movement of
the units must only be applied via the unit
base frame or shipping pallet.
NEVER LIFT THE UNITS BY COIL
CONNECTIONS OR BY ANY OTHER
PROTRUSIONS.
THE ROOF IS NOT DESIGNED TO BE
WALKED ON, BUT IF THIS IS
UNAVOIDABLE, ENSURE A MORE
EVEN WEIGHT DISTRIBUTION BY
THE USE OF BOARDS.
FAILURE TO DO SO MAY RESULT IN
SEVERE PERSONAL INJURY OR
DEATH.

Arrival/Off-Loading and
Movement To The Site
2.4 Forklift Trucks
The forks must only be applied under the
unit base frame and not against the unit
base frame. The lift point should be as
near as possible to the centre of gravity
(see Figures 4 and 4a). In the case of
larger units the use of several forklift
trucks may be required.
2.4.1. Roller Movement
Units fitted with base frames may be
moved on roller trolleys or tubular rollers
(see Figure 5).

3. Foundations and
Erection
3.1 Foundation
When selecting and preparing the unit
site, follow these guidelines:
1. Ensure that the site can support the
total weight of the unit. Unit weight
figures only provide total gross weights
and do not include the additional
weight for water in any coils.
2. Confirm that the foundation of the
mounting platform is large enough to
include the unit dimensions plus
service plus service access.
3. The floor or foundation must be level
for correct coil drainage and
condensate flow.
4. Provide adequate lighting for
maintenance personnel to perform
maintenance duties.
5. When the unit is positioned on site,
there must be sufficient space around
the unit to ensure that correct operation
and effective maintenance can be
carried out. Figure 6 gives
recommended space allowances.
•On the designated access side of the
unit, working areas must be equal to the
width of the unit, dimension “P.”
•Allowance for coil connections,
dimension “C” must be dimension “P” +
200 mm.
•A clear unobstructed area before and
after an air intake or discharge is
required to ensure correct air
movement. The width of the area must
be >= the width of the unit, and the
depth (dimension "L") must be >= 0.5 x
the overall unit height.
Complete reinforced concrete
foundations are suitable or strip
foundations may also be used (see
Figure 7).
In the case of strip foundations, concrete
or steel supports are permissible, but
support is required under breakpoints and
every 2 m along the unit base.

3.2 Erection
To minimize noise transmission,
insulation material such as cork slabbing
(TICO pads) may be placed between the
unit base and the foundation (see Figure
8).

4. Assembly and
Installation
4.1 Break Point and General
Unit Assembly
Instructions
Ensure that all the air-handling unit
sections are positioned in the correct
order.
Each section will display a unit drawing
with its position OUTLINED.
1. Each of the unit sections should be
placed on a level foundation and within
200 mm of its adjoining section.
2. Remove any supports and bracing
which are supplied with the unit for
transport. All such supports will be
clearly marked:
“FOR TRANSPORT ONLY –
REMOVE BEFORE ASSEMBLY”
3. Remove 4 M6 fixing bolts (A) from the
protruding portion of the 4 framework
joining bars (see Figure 9), then loosen
the remaining 4 bolts that are located
on the fixed side of the break point
joining bars.
Pull together the sections of the unit,
ensuring that the joiner bar in each of
the 4 corners is fitted into its adjoining
section and the plastic “T” section
sealing strip locates over the adjoining
panel.
The 52-mm diameter holes provided in
the unit base frame should be used to
manoeuvre the sections together.
Greased skid plates will greatly assist
the whole assembly operation.
4. Secure the break point joint externally
by replacing the 4 M6 bolts and
washers, which were previously
removed in step (3). Retighten the 8
bolts located on both sides of the break
point joint.
Where applicable, complete the
assembly of the unit as follows:
4.1.3. Fan sections
Bolt the outlet of the fan to the flexible
connection using the M8 bolts provided.
4.1.4. Damper sections
Pop-rivet through the damper spigot and
the adjoining plastic “J” section into the
adjacent fixed panel using 5-mm-
diameter rivets.
4.1.5. Coil sections (with drip pans)
Fix through the top of the drip pan into the
box section using the self-drilling screws,
which are provided. Then seal along all
joints with a waterproof “silicone” based
sealant. We recommend “Siloflex.”
4.1.6. Weatherproof roofs
Slide on the “Doby” cleats, which are
provided, and then fix in position at the
ends with the cleat clips on the roof return
edge using 5mm diameter rivets.

4.2 Stacked Units (Top and
Bottom)
Lower the top unit into position on top of
the bottom unit, taking care not to
damage the sealing gaskets.
Fit the self-tapping screws to the fixing
brackets, which are already positioned on
the top edge of the bottom unit,drilling into
the top unit section (10A) or base frame
(10B) depending on product, in order to
secure the top unit to the bottom unit (see
Figure 10).
Fix into position any internal joining strips
and/or brackets that are provided, and
then seal up any common sections in the
top and bottom units.
4.2.1. Stacked units (Side by Side)
Manoeuvre the two units into their correct
positions, taking care not to damage any
sealing gaskets.
Fix through the fixing brackets which are
located at both ends of the units in order
to secure the units together. Also fix into
position any base frame, unit end, and
roof joining brackets that are provided.
Fix into position any internal joining strips
and/or brackets that are provided, and
then seal up any common sections in
both of the units.
If you require further assistance or have
any questions please contact your local
Trane sales office.
4.3 Assembly of Flatpacked
Units
The unit is fully assembled in the factory
on a flat and level surface. Prior to
disassembly for flat packing (see Figure
11) all items are marked
alphanumerically. All items marked “A”
are joined at the fixing indicated at this
point. These markings are on labels on
internal surfaces so they are not evident
upon completion. DO NOT remove labels
until assembly is complete.
We would recommend opening one unit
at a time to avoid confusion.
