4 Unpacking and lifting
Always follow guidelines and instructions as given in the air cooler product manual AHE00042.
Arctigo ID air coolers are delivered in mounting position, mounted on wooden beams and a wooden
pallet on top. Handling and positioning can take place with use of a forklift. When more than one
cooler units are delivered in a single shipment, air coolers may be stacked during transportation.
Arctigo ID air coolers are to be unloaded one by one and lifted according to the following procedure:
Units must be unloaded and handled only from
the long side, one at a time.
In order to avoid damage to the driptrays or falling of the unit, ensure that the lifting forks cover
both inner support beams on the lower pallet.
AHE00054EN 1607

Place the unit on the ground and loosen the
fixing materials from the top pallet. Remove the
top pallet. Lift the unit into mounting position and
secure following instructions given in chapter "5
Installation".
Once the unit is secured in the installation position, loosen the fixing materials from the lower
support pallet and remove pallet.

6 Maintenance
Always follow guidelines and instructions as given in the air cooler product manual AHE00042.
Always disconnect power supply before any maintenance activities take place.
6.1 Fan replacement
Always disconnect power supply before performing any maintenance activities on fans and fan
motors.
Unscrew fixing bolts and remove old fan. Mount
new fan in identical position. Use an anti corrosion compound when remounting the fixing bolts.
Restore electric connection when the new fan
has been mounted.
6.2 Driptray
Driptrays can be opened for inspection, cleaning
and maintenance purposes. Always disconnect
drain line before opening the driptray.
Prior to opening, run a full defrost cycle to
remove any ice in the driptray. Ensure the driptray is empty before opening. The weight of any
leftover water could injure the service operator if
the driptray fell open accidentally.
To open tray, first loosen and remove fixing bolts
and then lower the drip tray.
6.3 Side covers
Respect the maximum opening angle to avoid
damage to the driptray hinges.
All side covers are hinged and can be opened
for inspection, cleaning and maintenance purposes.
To open side covers, loosen fixing bolts.

Always disconnect power supply before handling
defrost heater elements. Attention: heater elements can be hot!
To remove a pair of coil heater elements, open
side covers on both sides. Disconnect heater
element, remove fixing screws and extract elements from coil. Mount new elements in reverse
order, close side covers and restore electrical
connections.
Always disconnect power supply before handling
defrost heater elements. Attention: heater elements can be hot!
To remove driptray heater elements, open driptray.
Driptray defrost heaters
Fixing clips
Disconnect heater element. Bend slightly to take
the fixing clips out of their slots and gently slide
the heater element from under the clamps that
hold it to the bottom plate.
