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.

WARNING

2. Delivery Check On

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.
