1.3. SAFETY

General health and safety standards

The heat exchanger ORKA ST 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 device must be installed so that under normal operating conditions, there is no risk of contact with moving parts and power.
• The ORKA ST meets legal requirements for electrical equipment.
• Before working on the machine, always turn the power off.
• Use appropriate tools.
• Use the machine only for the purpose for which it is intended.

2. TECHNICAL INFORMATION

2.1. INTRODUCTION

ORKA ST 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%

By avoiding the heat exchanger, the by-pass system 100% of the ORKA product allows you to enter fresh night air without letting it warm up from contact with the hot air accumulated during the day. This system works manually (See chapter 5.2).

2.2. DESCRIPTION

• HR and ST: Extraction: 4 spigots d.80 +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 sufficient 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 air.

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.

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.

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 fi lter change:

The unit has a timer "12 months TIMER" that alerts the user when to change the filters.

5. CONTROL OF ORKA

5.1. INSTALLATION

5.1a. 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.

5.1b. Alarm change filters

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 flashing 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 2/3 seconds and the pilot light will illuminate a number of times to the number of months remaining to reach 12 months.

To confirm 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.

5.2. 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 airfl ow:

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.

6. COMMISSIONING THE ORKA
