Duct Connection, Cooldx Size; Duct Connection, Cooldx Sizes; Condensate Drainage From Cooling Coil; Supply Air Filter - Swegon CoolDX Series Installation And Maintenance Instructions Manual

3.3.3 Connection to GOLD units, CoolDX Sizes 20-60
Fit the sealing strip onto the GOLD unit's outdoor air and
exhaust air connections respectively. See the installation
instructions for the GOLD, as well.
If the CoolDX is to be docked directly against the GOLD
unit:
Use a forklift truck or a hand truck to position the CoolDX
against the GOLD unit as described in Section 3.3 Docking
Configurations. Make sure that the connections on the
GOLD unit and the CoolDX unit are in alignment and are
close to one another.
Important! Be careful to prevent damage to the unit!
Joint the connections together with slip clamps (acces-
sories: TBLZ-2-aa-08 slip clamps ). See the installation
instructions for the GOLD.
Distance, GOLD/CoolDX
GOLD
If the CoolDX is to be located at another place:
Position the CoolDX at an appropriate place in the fan
room. Connect ducts between the GOLD unit and the
CoolDX unit, arranging the connections as described in
Section 3.3 Docking Configurations.
Joint the ducts and connection spigots together with slip
clamps (accessories: TBLZ-2-aa-08 slip clamps ). See the
installation instructions for the GOLD.
It may be necessary to extend the communication cable
and necessary tubing (not included in the supply) de-
pending on the distance between the GOLD unit and the
CoolDX unit.

3.3.4 Duct connection, CoolDX Size 08-12

Fit rubber ring seals (not included in the supply) to the
CoolDX for connection to circular ducting. See the installa-
tion instructions for the GOLD, as well.

3.3.5 Duct connection, CoolDX Sizes 20-60

The size 20-60 CoolDX cooling units have rectangular con-
nections. Use slip clamps (accessories: TBLZ-2-aa-08 slip
clamps) for jointing to ducts.
3.3.6

Condensate drainage from cooling coil

The cooling unit is equipped with a drain tray below the
cooling coil for collecting condensate that drips from coil
surfaces.
We reserve the right to alter specifications.
The condensate discharge pipework shall be connected
across a water trap (accessory) to the drain connections of
the cooling unit and shall run with continuous slope to a
drain gulley.

3.3.7 Supply air filter

The CoolDX is supplied with its own supply air filter. Con-
sequently, the supply air filter in the GOLD unit should be
dismantled.
The hoses for measuring air pressure drop across the
supply air filter are supplied in the CoolDX and are con-
nected inside the CoolDX at the factory. These hoses must
however be connected to supply air filter pressure drop
measurement hoses inside the GOLD unit. To do this,
proceed as follows:
Extend the hoses from the CoolDX unit, through the duct
connections of both units to the extract air fan space in-
side the GOLD unit. Disconnect the existing filter pressure
drop hoses from the pressure drop measurement nipples
in the intermediate deck of the GOLD. To prevent leakage,
use an appropriate sealant to seal the nipples in the inter-
mediate deck.
IMPORTANT! Do not disconnect the hoses from the pres-
sure transducer as doing so is likely to damage the hose
connections on the pressure transducer.
Connect the blue hose from the CoolDX to the blue hose
from the pressure transducer of the GOLD unit using the
interconnection nipples supplied. Connect the white hoses
in the same way. See above sketch.
IMPORTANT! There are other variants besides those
shown in the sketch. See Section 3.3 Docking Configura-
tions.
Position and secure the hoses by means of bundling straps,
for example.
