2. General

2.1 Handling the air handling
unit before commissioning
The air handling unit and its duct connections should be pro-
tected against wetness and condensation until the unit is com-
missioned.

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.
The GOLD CX units can also be used for the ventilation of mod-
erately humid buildings; however not where the humidity is
continuously high, such as in indoor swimming baths.
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 design 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).
GOLD CX is designed and tested for temperatures, in the sur-
roundings and the air stream, from -40°C to +40°C. If the air
handling unit is placed outdoors, the expansion vessel must be
equipped with anti-freeze resistance and insulated when the
design outdoor temperature is lower than -10 °C.
The fans are approved for continuous operation in temperatures
of up to 40°C.
The fans are tested for, and can manage operation for one hour
at 70°C.
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 CX units are available in 4 physical sizes and for 8
airflow ranges.
The outer sheet steel skin is painted in Swegon's grey metallic
colour (closest RAL colour: 9007). The handles and decor strips
are black. Internal material: aluminium-zinc plated sheet steel
and Magnelis. Environmental Class C4. Panel thickness of 52
mm with intervening insulation consisting of mineral wool.
The GOLD CX units have class ePM10 60% (M5) or ePM1 50%
(F7) supply air and extract air filters made of glass fibre.
The coil heat exchangers in the size 035-080 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. A pipe coupling unit
supplied in unmounted condition is available as an accessory for
the size 100/120 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 control system 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, Operation times
and a large number of internal and external functions as well as
alarms.
