2. General
2.1 Handling of air handling
units before commissioning
The air handling unit and its duct connections should be protec-
ted against wetness and condensation until the unit is commis-
sioned.
2.2 Range of Application
The GOLD units are designed for use in comfort ventilation appli-
cations. Depending on the variant selected, GOLD units can be
utilised in buildings such as office buildings, schools, day nurser-
ies, public buildings, shops, residential buildings, etc.
GOLD units equipped with plate/coil heat exchangers (PX/CX)
and separate supply air and extract air handling units (SD) can
also be used for the ventilation of moderately humid buildings;
however not where the humidity is continuously high, such as in
indoor swimming baths.
The separate GOLD supply air and extract air handling units (SD)
are designed for applications in which the supply air and extract
air flows need to be completely separated from one another or
where, due to limited available space, separate units for supply
air and extract air respectively are needed. They can also be used
individually if only one of the variants is needed.
In order to fully obtain all the benefits the GOLD system has to
offer, it is important to take the special characteristics of the air
handling units into account when planning them into the pro-
ject, installing, commissioning and operating them.
The air handling unit in its basic version should be installed
indoors. The TBTA/TBTB accessory should be used if the air
handling units are installed outdoors. If the duct accessories are
installed outdoors, they must be housed in an insulated casing
(type TCxx).
Important!
Always read the safety instructions in Section 1 that
explain the risks involved in running the unit and desig-
nate who shall be permitted to operate and service the
unit, and carefully follow the installation instructions
provided in each paragraph.
The product identification plates are located on the inspection
side of the air handling unit and on a wall inside the fan section.
Refer to the particulars on the product identification plate when
you contact Swegon.
2.3 Mechanical Design
The GOLD is available in 9 physical sizes and for 18 airflow
ranges.
Its sheet steel exterior is painted in a beige colour. NCS S2005-
Y30R. Handles, decorative strips and the upper part of the junc-
tion hood are painted dark grey, NCS S 8502-B.The lower part
of the junction hood is painted black, NCS S 9000-N. The inner
skin material is aluminium-zinc coated sheet steel. Environmental
class C4. Panel thickness of 52 mm with intervening insulation
consisting of mineral wool.
The size 11-30 GOLD units with plate heat exchanger (PX) or
rotary heat exchanger (RX) with air intake from above and the
separate size 04-08 supply air and extract air units (SD) as well as
the GOLD RX Top are equipped with pleated, class F7 filters. The
units in other variants/sizes have class F7 supply air and extract
air filters made of glass fibre.
The type RECOnomic rotary heat exchanger is variable speed
controlled and has a temperature efficiency of up to 85%.
The plate heat exchangers are as standard equipped with bypass
and shut-off dampers for variable and automatic control of the
heat exchanger’s efficiency on heat recovery.
The coil heat exchangers in the size 35-80 one-piece GOLD CX
air handling units are supplied completely mounted from the fac-
tory; including mounted pipework package with all the necessary
components. The system is normally filled with liquid, vented,
commissioned and performance-tested prior to delivery, but can
also be ordered in unfilled condition e.g. for housing improve-
ment projects or if the application requires filling with another
mixture instead of 30 % ethylene glycol. Pipework packages
in unassembled form are available for the size 100/120 GOLD
CX one-piece units and for the size 12-120 GOLD SD separate
supply air and extract air handling units.
The supply air and extract air fans are of GOLD Wing+ type, an
axi-centrifugal fan with backward-curved blades. The fans are
direct-driven and have a motor controller for variable speed
control.
2.4 Control System
The IQlogic control system is microprocessor-based and is inte-
grated into the air handling unit. It controls and regulates the
fans, heat exchanger, temperatures, airflows, in operation times
and a large number of internal and external functions as well as
alarms.
2.5 Environm. Documentation
For a complete Declaration of Construction Materials, see our
home page at www.swegon.com (applicable to Sweden only).
The air handling unit is designed in such a way that it can be
dismantled into its natural parts for scrapping. When the unit has
ended its useful product life, the services of an accredited recy-
cling company should be utilised for disposal.
The recyclable weight of the GOLD is about 94% of its initial
weight.

Contact Swegon AB, Phone: +46 (0)512-322 00, if you have
any questions regarding the dismantling instructions or the air
handling unit’s impact on the environment.
2.6 Type of Heat Exchanger
The GOLD one-piece air handling unit is supplied with either a
rotary heat exchanger (RX), plate heat exchanger (PX) or coil heat
exchangers (CX). A coil heat exchanger is available as an option
for the separate supply air and extract air handling units (SD).
If any section, function, etc. deals only with one type of heat
exchanger, it is marked with an appropriate symbol as speified
below:

exchanger (RX)
Coil heat exchangers
(CX, possibly SD)
Plate heat ex-
changer (PX)
