GENERAL RECOMMENDATIONS
The heat exchanger ORKA HR has been designed to be incorporated into a ventilation system. Following installation, there should be no risk to safety, health and the environment according to EC directives. This also applies to other products used in the installation.
The following general guidelines are important:

Follow the safety instructions to prevent injuries and damage to the motorised fans.
The technical characteristics described in this manual may not be changed.
The motorised fans must not be modified.
The motorised fans must be supplied with a single phase AC supply of 230 V / 50 Hz.
So that the installation complies with EC directives, the ORKA HR must be connected to the electricity grid according to current national standards.
The ORKA HR meets legal requirements for electrical equipment.
Use appropriate tools.
Use the machine only for the purpose for which it is intended.

TECHNICAL INFORMATION

INTRODUCTION
ORKA HR ensures optimal ventilation of the house with maximum energy recovery. Stale air is extracted from the “wet” rooms (bathrooms, toilets, laundry rooms, etc.) and fresh air is supplied into the main “habitable” rooms (living room, bedrooms,studys,…). Both airflows are filtered before forwarding to the heat recovery unit, where warmth from the stale, outgoing air is transferred to the cooler incoming airflow. The unit performance can reach:

HR: 92%
ST:70%

In this exchange, water is generated due to condensation forming as the warm outgoing air rapidly cools. It is essential that this water is properly drained away from the unit via the supplied condensate drain pipe.

ORKA HR has a 100% bypass that allows fresh air from outside to be introduced directly, without receiving the heat energy from the extraction air, generating free cooling. It is a manual activation.

DESCRIPTION

HR and ST: Extraction: 4 spigots d.80 + 1 spigot d.125.
HR D150 and STD150: extraction: 1 spigot d.150 and 1 spigot d.125.
The rest of connections: 3 x d.125 (adapter 125/150-160 supplied for each spigot)

New fresh air inlet:
This spigot is to connect the supply duct of fresh air from outside.
Install the fresh air intake (wall or roof) a suffi cient distance from any area of high pollution (trees, exhaust fumes, road, etc).

This duct must be sealed and insulated to prevent condensation on the outside and inside.

Supply fresh air into the building:
Connected to the air intake duct in the property.
To avoid thermal losses, it is recommended to use insulated ducts for the warmed

Extract air from the building:
Connected to the extract duct from the property.
To avoid thermal losses and optimise the performance of the installation, it is recommended to use insulated ducts for the warm air

Discharge of extract air:
Connected to the discharge duct to the outside

This duct must be well sealed and thermally insulated to avoid condensation both on the inside and outside.

By-pass :
The 100% by-pass system of the ORKA allows the introduction of cooler fresh air (during the evenings and in the night) avoiding the heat exchanger and thus without it being tempered by the outgoing warm air which has accumulated in the house during the day

Alarm filter change:
The unit has a timer “12 months TIMER” that alerts the user when to change the fi lters

DIMENSIONAL CHARACTERISTICS

**Central

**

**Remote control

INSTALLATION

The equipment must be installed in a heated room in the home (>10ºC) if this is not possible, the condensate outlet must be thermally isolated

In areas that regularly have negative temperatures (<-2ºC) a pre-heating battery must be installed. Operating temperature (<-2ºC, 45ºC)

Ducts must be thermally insulated and correctly installed

**Spigot arrangement Ø 80 mm

**

**Spigots that are not used must be plugged with the supplied accessory.

MOUNTING IN A FALSE CEILING
To ensure correct installation, it is necessary to place the supplied positioning accessories as indicated:

Extraction: without accessories

For correct maintenance, a sufficiently large equipment access hatch must be installed.
Recommended Dimensions: 1000 x 750 mm.

MOUNTING IN A FLOOR
To ensure correct installation, it is necessary to place the supplied positioning accessories as indicated

discharge side: without accessory
Product Overawe

For correct maintenance, access must be allowed to the equipment to each exposed side.
Access is from the top

SAMPLE “MIXED DISTRIBUTION” ASSEMBLY

The use of flexibleduct must be reduced to short sections and must be correctly stretched.

It is recommended not to put the RDR flow regulator on a branch, both in extraction (kitchen) and in supply (living room) to take advantage of the peak fl ow activated by the remote control.

SAMPLE “PLENUM DISTRIBUTION” ASSEMBLY

The use of flexible duct must be reduced to short sections and must be correctly stretched.

It is recommended not to put the flow regulator on a branch, both in extraction (kitchen) and in supply (living room) to take advantage of the peak fl ow activated by the remote control.

CONTROL OF ORKA

INSTALLATION

1a. Airflow selection

The equipment has 2 configurations (A and B) for low speed depending on the connection (see chapter 4). The peak airflow (high speed) function is common to both configurations.

1b. Alarm change fiiters

The unit has a timer “12 months TIMER S&P” that alerts the user when to change the filters. It is a movable device and must be located where the user can view the alarm status.

The alarm is timed to activate at 12 months. Once this time has elapsed, the pilot will light up every 10 seconds during the first 4 days. Subsequently, the fl ashing will be every 30 seconds for the next 9 days.

When the filters have been changed, the alarm must be reactivated by pressing the button for 5 seconds.

To check the remaining time until the end of the timing, press the button for 3 seconds and the pilot light will illuminate a number of times to the number of months remaining to reach 12 months.

Toconfi rm that the battery has sufficient charge, press the button (<1 second) and the pilot light will illuminate once.
If not, the battery should be replaced with a new one. The remaining time for the alarm activation is saved.

The battery life for normal use is approximately 3 years.

The battery is CR2032 type.

Remove the battery protection for activation.

DURING USE

The remote control allows the user to:

Activate the peak airflow
Activate the by-pass 100%

Low airflow:
Activates the low airflow corresponding to curve A or B depending on the configuration chosen in the
electrical connection.

Peak airflow:
Peak airflow activation

By-pass (ON/OFF):
By avoiding the exchanger, the 100% ORKA bypass system allows fresh air from outside to be introduced without being overheated by the outgoing air from indoors, this is mainly recommended in summer to get free cooling. Manual activation.

COMMISSIONING THE ORKA

To start your ORKA unit use the following process:

Verify that all system components are correctly installed and connected:
- Fresh air intake duct insulated and connected correctly (Do not use a fresh air intake equipped with insect screen).
- Fresh air and exhaust ducts insulated and connected correctly.
- Fresh air and exhaust vents connected.
- Flow regulators mounted in the right direction (if installed).
- Air outlet using insulated duct and connected to the outside (Using a roof cowl or outlet without an insect screen).
- Insulated fl exible ducts taut and large radius bends (if installed).
- Check that the unused spigots on plenums are sealed (if installed).
- Condensation drain well connected (siphon).
- Check that all connections are sealed (on the ORKA, on plenums and vents).
- Check the setting of the power circuit breaker.
Turn on the ORKA, checking the selected speed.

MAINTENANCE

In order to take advantage of the equipment’s services throughout its useful life, it is essential to carry out maintenance tasks correctly.

Every 12 months: change the filters. The unit is supplied with 1 x M5 filter in the outdoor air side and 1 x G4 filter in the extract air side.

The supply filter M5 can be replaced by a G4 filter if required (filters replacement sets with 2 filters per set are sold as accessories).

Filters replacement set M5 + G4: 5416996500 KIT M5/G4 ORKA
Filters replacement set G4 + G4: 5416996600 KIT G4/G4 ORKA

Alarm Reset of the fi lter change (see chapter 5.1 B)
Maintenance

Every 24 months: remove dust from inside of the heat recovery unit with a vacuum cleaner.
Every 6 months: clean the extraction spigots of kitchen and bathroom with warm water and soap.
