Thank you for purchasing an AIR HEATER or a DESTRATIFIER from the CARRIER 42AM range. We trust that this unit will give you
complete satisfaction.
To ensure correct operation, all connections (electrical, hydraulic, etc.) must be made in accordance with industry practice and the
regulations in force in the country of use.
Your unit must be maintained as recommended in this manual
1 - RECEIPT OF THE UNIT
The unit is supplied with a label on the packaging detailing all the specications of the unit used to identify it (type, model etc.).
Each device bears a name plate. The reference number shown on the name plate must be quoted in all correspondence.
It is the recipient's duty to inspect the contents of the packages upon receipt:
■In the event of missing items, the customer must provide the exact number of parcels delivered.
■All damaged or missing items must be reported on the delivery note in the presence of the driver before the delivery note is signed.
IMPORTANT: In accordance with Article 133 of the French Code of Commerce, these claims must be reported to the carrier by
registered letter within three business days of receipt. The terms "conditional" and "pending unwrapping" shall have no value. The
customer must unwrap the goods in the presence of the driver. Damage/shortages must be noted at time of delivery and described in
detail. An air heater operating with more than 10% fresh air is not compliant with the Regulation (EU) No. 1253/2014.
2 - HANDLING
Handle the unit with care.
The unit can be installed with a forklift truck using the slings. These should be positioned on the 2 lifting rings as shown in the diagram

6 - SETUP
6.1 - 42AM air heater
To ensure correct air diffusion and to comply with the EN 294 standard relating to safety
zones, you are recommended to position AIR HEATER units at a height of:
■Between 2.5 and 4.5 metres when wall-mounted
■Between 4.5 and 10 metres when ceiling-mounted.
The rear of the unit must be at a sufcient distance from the wall to facilitate removal of
the fan motor assembly when necessary.
6.2 - 42AMA Destratier
It is recommended that destratiers are positioned at a height of 5 to 15 metres.
The rear of the unit must be at least 145 mm away from any walls to facilitate removal of the fan
motor assembly when necessary.
6.3 - Wall-mounting the 42AM air heater
Installation using wall-mounting support kit
Installation mainly for HEATING purposes

Assembly procedure:
1. Pre-assemble the clamping plates on the brackets using the
Ø 8 mm serrated washers and the H M8 nuts (not tightened).
2. Fit the bracket assemblies onto the support tubes by sliding
them over the end.
3. Fix the legs of the wall bracket (7181226) using the 4 H M8x70
screws, the 4 x Ø 8 mm plain washers, the 4 x Ø 8 mm serrated
washers and the 4 x H M8 nuts, allowing the distances detailed
above.
4. Move the support assembly onto the IPN and slide the bracket
assemblies so that the lips are clamped onto the IPN. Tighten
the bracket nuts to lock the assembly in place.
5. Fix the AIR HEATER unit using the 4 x H M8 x 50 screws
supplied with the wall bracket.

6.4 - Ceiling-mounting the 42AM air heater
Installation with ceiling-mounting kit
Installation only possible for HEATING applications.
Ceiling mounting using uids at temperatures above 90°C is prohibited if the heat exchanger is still supplied with uid when
the ventilation is switched off. (Motor warranty invalidated if the motor is damaged due to the thermal inertia of the coil)
Bracket identical on all 4 sides
M8 metric screws
M8 insert
To be provided by the client:
-M8 threaded rods
-Lock nuts underneath the inserts
Assembly procedure:
1. Remove the 8 x M8 screws. (Upper and lower section of the AIR HEATER)
2. Fit the ceiling brackets and ret the M8 screws in their original locations.
