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 proce-
dure:
Units must be unloaded and handled only from
the long side, one at a time.
In order to avoid damage to the driptrays or fall-
ing of the unit, ensure that the lifting forks cover
both inner support beams on the lower pallet.
4 Unpacking and lifting
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 posi-
tion, loosen the fixing materials from the lower
support pallet and remove pallet.

5.4 Drip tray drain
The drain line diameter must be at least the size
of the drip tray drain diameter and should be laid
with an adequate slope. For room temperatures
below 0° C drain line insulation and an inter-
nal or external heating element are required to
prevent freezing .
A syphon must be installed on the drain line,
outside the cold room
Tighten drain connection by hand only.

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 perform-
ing any maintenance activities on fans and fan
motors.
Unscrew fixing bolts and remove old fan. Mount
new fan in identical position. Use an anti corro-
sion 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 drip-
tray 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.
Respect the maximum opening angle to avoid
damage to the driptray hinges.
6.3 Side covers
All side covers are hinged and can be opened
for inspection, cleaning and maintenance pur-
poses.
To open side covers, loosen fixing bolts.

side covers on both sides. Disconnect heater
element, remove fixing screws and extract ele-
ments from coil. Mount new elements in reverse
order, close side covers and restore electrical
connections.
6.5 Driptray defrost element replacement
Always disconnect power supply before handling
defrost heater elements. Attention: heater ele-
ments can be hot!
To remove driptray heater elements, open drip-
tray.
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.
Mount new element in reverse order, close drip-
tray and restore electrical connections.
