Flexible connectivity options
The innovative design of the unit allows for several different connection options. Supply, extract, outdoor and exhaust air each have two connections. For example, both exhaust air outlets can be used if two connections for exhaust air are required. Supply air, on the other hand, can only be connected to one spigot, as the duct battery can only be fitted to one supply air duct.
The same unit can therefore top connected, laterally connected or L-connectors. An example is an installation where only the exhaust air is connected at the top while the other ducts are connected at the side.
The connections that are not used are covered with the supplied cover.

Installation Instructions
Art. no.: 33040
•
EAN: 7350070006215
General
Installation and commissioning shall be carried out by qualified personnel with the necessary professional knowledge to ensure correct operation.
Suitable location is in a fan room, storage room or similar space. The unit can also be placed in a cold room. Delivery is in right-hand version but can easily be changed to left-hand version.
The unit is equipped with six connection sockets, four of which are used. The connections used depend on the connection variant selected (see next page). The two connection sockets that are not used are fitted with the covers supplied.
The unit has inspection hatches on both sides to allow multiple connection options. The heating coil and possibly the cooling coil are placed in the supply air duct.
The minimum service space in front of the inspection hatch is 950 mm, to enable the replacement of all components.
Flow metering outlets
For each fan there are pressure measurement sockets for flow measurement:
- R25 = 2000-2-2945 / 52
- R40 = 28004-2-4013 / 21,4
- R50 = 28004-2-4013 / 21,4
- R70 = 31002-2-4013 / 25,8
There are two measuring sockets under the metal cover.
Heating and cooling battery
The electric battery is installed in the supply air duct and is provided with its own power supply. The electric battery is interlocked with an internal flow switch.
Water coil kit for heating and cooling contains duct coil, valve actuator, control valve and anti-freeze sensor. Supplied complete with connection instructions.

Determining connection variants
Right variant = Supply air to the right (delivery version)
- Parameter 100 is set to the upper position on delivery, which means that the right (upper) fan is the supply air fan.
- Decide which connections to use at the top and side respectively. Other connections are covered with the supplied cover.
- Install duct coil for heating and possibly cooling in the supply air duct and possibly damper in the outdoor air or exhaust air duct. The cooling coil must be installed in a horizontal duct due to condensation traps.
- Install the labelled temperature sensors in each duct: supply, extract and outdoor air.
- Green colour = Outdoor air
- Blue colour = Supply air
- Gul = Exhaust air
- Brown = Exhaust air
Left variant = Supply air to the left (change parameter 100 to lower)
- Green colour = Outdoor air
- Blue colour = Supply air
- Gul = Exhaust air
- Brown = Exhaust air
- Change parameter 100 to lower position, which means that the left (lower) fan is the supply air fan.
- Decide which connections to use at the top and side respectively. Other connections are covered with the supplied cover.
- Install duct coil for heating and possibly cooling in the supply air duct and possibly damper in the outdoor air or exhaust air duct. The cooling coil must be installed in a horizontal duct due to condensation traps.
- Install the labelled temperature sensors in each duct: supply, extract and outdoor air.

Commissioning
When commissioning, air flows must be adjusted so that the exhaust air flow is 10-15% higher than the supply air flow (negative pressure) for safe operation. Applies to all operating modes.
Important to consider when installing
- Installation and commissioning shall be carried out by a person with sufficient professional knowledge to ensure proper functioning.
- If the system is not commissioned immediately, all duct connections should be sealed inside the unit to prevent moist or cold air from entering and causing moisture damage.
- All operating modes shall be adjusted (Spruce, Comfort and convenience and Forcing).
- The control panel should be positioned so that the user has good access and overview in the event of an alarm.
- The user/manager of the installation shall be informed of the location of the control panel and its functions.
- The installer shall hand over the manuals and the guarantee certificate to the user/manager of the installation.
- The product must be registered at www.acetec.se for the guarantee to apply.
- Original filters must be used during the warranty period for the warranty to be valid.
