User Manual for Innova 100H Heat Recovery Unit

Quick guide from the manual

This manual provides essential instructions for the installation, operation, and maintenance of the Innova 100H heat recovery unit. Before starting, ensure the unit is not powered. Installation must be performed by qualified personnel. Key requirements include a 230V single-phase power supply, proper condensate drainage with a siphon, and adequate space for maintenance access.

Main Components

The unit consists of several key parts:

• Heat recovery core
• Inlet and exhaust fans
• Finned batteries
• Electrical cabinet
• Recirculating air damper
• Air filters

Installation

The unit can be installed on the ceiling or floor. Ensure the mounting surface is strong enough to support the weight and will not cause vibrations. Do not mount the unit with sides in direct contact with walls to avoid noise; use rubber or neoprene strips if necessary.

Condensate Drain Connection

Proper drainage is critical to prevent moisture buildup. Ensure a slope of at least 2% at the outlet pipe. A siphon must be installed and kept full of water, with dimensions H1 > 40mm and H2 > 40mm.

Aeraulic Connections

The unit features four circular rear connections and a rectangular front port. Refer to the unit's stickers for correct ducting. It is recommended to use at least 500mm of flexible piping to reduce vibration and noise.

Plumbing Connections

The unit uses hydronic coils. Respect the IN (inlet) and OUT (outlet) markings. Ensure piping weight does not bear on the connections. Water quality must meet specific limits, including hardness < 10°F and pH between 7.5 and 9.

Electrical Connections

All electrical work must be done with the power disconnected. Use a dedicated power supply circuit and install a circuit breaker. The unit must be grounded. Wiring diagrams are provided in the manual for specific versions. For multi-unit control, use an RS485 network with shielded 2-wire cable, terminating the line with the provided 120 Ohm resistor.

Operation

The unit is controlled via a wall-mounted touch panel. Users can adjust fan speeds (Silent, Nominal, Maximum), change seasons (Winter/Summer), and set temperature or humidity set points. The 'Auto' function uses humidity and air quality sensors to regulate airflow.

Maintenance

Regular maintenance is required for optimal performance:

• Filters: Clean or replace periodically. Access via dedicated knobs.
• Heat Exchanger: Verify status during filter changes. Clean gently with a vacuum or low-pressure compressor.
• General Cleaning: Periodically clean fans, condensate drain, and internal walls. Do not remove balancing clips from fan blades.

Alarm

If an alarm occurs, an error code will appear on the display, or an LED on the electronic board will flash. Note the error code and contact your installer. Common issues include display failure (check power/fuse), low airflow (check filters/exchanger), or high noise (check panels/siphon).
