months from the date of commissioning or 18 months from the date of despatch, whichever is
the sooner.
Parts or Equipment supplied by AIAC for installation within the UK or for Export that are
properly commissioned in accordance with AIAC standards and specification, not
commissioned by an AIAC engineer; carry a 12 month warranty on non consumable Parts only
from the date of commissioning or 18 months from the date of despatch, whichever is the
sooner.
Parts or equipment installed or commissioned not to acceptable AIAC standards or
specification invalidate all warranty.
Warranty is only valid in
the event that
In the period between delivery and commissioning the equipment: is properly protected &
serviced as per the AIAC installation & maintenance manual provided where applicable the
glycol content is maintained to the correct level.
In the event of a problem being reported and once warranty is confirmed as valid under the
given installation and operating conditions, the Company will provide the appropriate warranty
coverage (as detailed above) attributable to the rectification of any affected Airedale equipment
supplied (excluding costs for any specialist access or lifting equipment that must be ordered by
the customer).
Any spare part supplied by Airedale under warranty shall be warranted for the unexpired period
of the warranty or 3 months from delivery, whichever period is the longer.
To be read in conjunction with the Airedale Conditions of Sale - Warranty and Warranty
Procedure, available upon request.
Procedure
When a component part fails, a replacement part should be obtained through our Spares
department. If the part is considered to be under warranty, the following details are required to
process this requirement.
Full description of part required, including Airedale's part number, if known
The original equipment serial number
An appropriate purchase order number
A spares order will be raised under our warranty system and the replacement part will be
despatched, usually within 24 hours should they be in stock.
When replaced, the faulty part must be returned to Airedale with a suitably completed and
securely attached "Faulty Component Return" (FCR) tag. FCR tags are available from Airedale
and supplied with each Warranty order.
On receipt of the faulty part, suitably tagged, Airedale will pass to its Warranty department,
where it will be fully inspected and tested in order to identify the reason for failure, identifying at
the same time whether warranty is justified or not.
On completion of the investigation of the returned part, a full "Report on Goods Returned" will
be issued. On occasion the release of this complete report may be delayed as component
manufacturers become involved in the investigation.
When warranty is allowed, a credit against the Warranty invoice will be raised. Should warranty
be refused the Warranty invoice becomes payable on normal terms.
Exclusions
Warranty may be refused for the following reasons:
Misapplication of product or component
Incorrect site installation
Incomplete commissioning documentation
Inadequate site installation
Inadequate site maintenance
Damage caused by mishandling
Replaced part being returned damaged without explanation
Unnecessary delays incurred in return of defective component
Returns analysis
All faulty components returned under warranty are analysed on a monthly basis as a means of
verifying component and product reliability as well as supplier performance. It is important that
all component failures are reported correctly.

Standard Features
FAN & MOTOR ASSEMBLY
All Models
The external rotor AC motor shall allow the use of a low power output, single phase, and
speed controllable motor to power the fan.
The motor shall have inbuilt thermal overload protection and the assembly shall be
supplied complete with a finger guard for protection.
Shall be available in either horizontal or vertical air discharge orientation, please specify
at order.
ELECTRICAL
All electrical components shall be rated for all year round outdoor use.

Optional Extras - Energy Saving
ELECTRONICALLY
COMMUTATED (EC) FAN
MOTOR
Shall incorporate external EC rotor motor technology to provide highly accurate
discreet speed control. The fans offer maximum air flow performance while keeping
sound levels to a minimum.
Each fan shall incorporate electronically commutated DC motor control using semi-
conductor modules responding to a signal from the Airedale indoor unit.
EC motors are DC motors with integrated AC to DC conversion; this gives the
flexibility of connecting to AC mains with the efficiency and simple speed control of a
DC motor. The EC fan shall offer significant power reduction in comparison with
equivalent AC fan at both full and modulated fan speeds. The inbuilt EC fan control
module shall allow for fan speed modulation from 0-100%, the modulating range of a
standard AC fan is typically 40-100% of full fan speed.
Optional Extras – General
SHORT CASE AXIAL FANS
(SCAF)
Short case axial fans shall be supplied for indoor installations where discharge air
requires to be ducted to an outdoor location. The fans shall meet duty plus nominal
75Pa of external static pressure.
CORROSION RESISTANT
COATED COILS
For aggressive atmospheres a corrosion resistant coating shall be applied to the
aluminium fins.
SHUT OFF VALVES
Where unit isolation for easier maintenance is required, shut off valves shall be
supplied loose for on site fitment.
COIL GUARDS
Protective mesh guards can be fitted to each of the outer coils to protect against
damage.

Unit Lifting
GENERAL
Employ lifting specialists
Local codes and regulations relating to the lifting of this type of equipment should
be observed
Each chain/sling must be capable of lifting the whole unit
Lift the unit slowly and evenly
IMPORTANT
Only use lifting points provided.
Do not use 1 chain between 2 lifting points to avoid load shift.
Ensure that chains/slings DO NOT crush the casework, coil or fan assemblies.
If the unit is dropped it should immediately be checked for damage and reported
to Airedale.
Airedale will accept no responsibility for mishandling during the positioning of
the equipment.
CAUTION
Check the unit is as ordered, discrepancies or transit damage should be reported
to Airedale immediately.
HORIZONTAL AIR
DISCHARGE
The unit is delivered in horizontal air discharge configuration secured to a pallet. Where
possible the unit should be moved with the pallet in place.
Use 4 lifting eyes attached to 4 individual slings/chains
(supplied by others) and attach 2 to each top leg using
the holes provided as illustrated.
VERTICAL AIR
DISCHARGE
The unit is delivered in horizontal air discharge configuration (with the mains isolator and
fan speed controller already configured for vertical air discharge) secured to a pallet.
Where possible the unit should be moved with the pallet in place.
Before lifting into final position, the unit legs should be re-orientated, refer to instructions
provided at delivery.

Sound Data
METHOD OF SOUND
MEASUREMENT
All sound data quoted has been measured in the third-octave band limited values, using
a Real Time Analyser calibrated sound intensity meter in accordance with
BS EN ISO9614 Part 1: 1995.
All Sound Power Levels quoted are calculated from measured sound intensity according
BS EN ISO9614 Part 1: 1995.
SEMI HEMISPHERICAL
Sound Pressure Levels are calculated from sound power using the semi-hemispherical
method where the noise source is in junction with 2 boundaries i.e. the floor and 1 wall.
SOUND DATA - STANDARD FAN
IMPORTANT
The sound data quoted is based on the unit having the STANDARD FAN running at
FULL SPEED under normal operating conditions.
For sound data of optional fan selections, please contact Airedale.
