envirovent SABIK 350-500 Heat Recovery Unit User Guide

Whole House Heat Recovery System

What is it and why is it there?
The Sabik 350 and 500 are centralized heat recovery ventilation units that continuously remove stale, moist air from your bathroom, kitchen, WC and replaces it with clean fresh tempered air through circular valves mounted in your ceiling and into your living room areas.
The unit also helps to maintain good thermal comfort; ventilation airflows help heat to mix from different sources, so it circulates throughout your
home, especially from the central heating system during cold periods.

How will it help?

It will prevent the build-up of moisture in the house, remove steam/condensation and odours during bathing and cooking, prevent black moulid
forming on the walls, behind cupboards etc.
It will also help stop the dampness that you can get in your cupboards and wardrobes, on your clothes and furnishings, caused by poor ventilation.
It provides continuous, all year round ideal indoor air quality.

How do I control it?

The system operates continuously 24 hours a day at a low rate known as ‘trickle’, to ensure your home is ventilated at the appropriate level.
The system can be sent into a higher rate called ‘boost’ via the touchscreen controller to rapidly remove excess moisture or odours.
Your unit will automatically control the humidity levels in the home quietly and efficiently

Remote Control Versions
The Sabik 350 and 500 come with a wired touchscreen controller as standard.
The functions of the controller are seen in the table below:

Press for 1 second| Result| Press for 5 Seconds| Symbol displayed
---|---|---|---
| Boost and reduce the unit depending upon the number of presses.| | | Unit shuts down for one hour.
| Boost and reduce the unit depending upon the number of presses.| | | The unit will enter automatic mode if a weekly program me is activated or there is a specialist sensor installed.
| Boost the unit, this can be set by a timer for a specific period.| | | Filter reset. The filter should be checked, cleaned and potentially replaced before this is reset.
| The summer bypass becomes active for 8 hours. This would be used in periods of excessively hot weather.| | | This activates the summer bypass to prevent warm air entering the dwelling. If the outdoor temperature is >13°C this is an automatic function.
| | | | In periods of cold weather, if the preheater is not installed and there is a risk of freezing, the supply airflow will switch off and the unit will enter frost protection mode. When this is displayed, the unit is in frost protection mode.

For further information, on the controls and their functions, please consult the installation guide.
Do not permanently turn off the mechanical ventilation systems or block permanent vents.
If you feel drafts when the system is running, first check if boost mode has been turned on, and if needed change this back to normal mode.
If you permanently turn off mechanical ventilation systems, your home will be poorly ventilated, causing high humidity and an increase in other
indoor air pollutants.
Turning off the unit may also damage the system and invalidate the warranty.

Summer bypass

This feature is included as standard and helps to reduce the air temperature coming into the dwelling during the warmer periods.
It is an automatic function and operates when the supply air temperature to the property is above 13 degrees Celsius, reducing the warming of incoming air (from outdoors) by the extracted indoor air.

Staying cool in hot weather

Public Health England cautions that prolonged periods of extremely hot weather pose serious health risks.
For guidance about this, please consult the following website, which includes advice on protecting yourself and your dependents:

During normal operation, the MVHR unit warms up the outdoor air supplied to the indoors using the warm air extracted from your home.
This means the central heating system does not need to supply this part of the overall heating needed for your home, which is likely to decrease your total energy costs compared to other types of ventilation systems.

Maintenance

More detailed instructions for maintenance are included in the Installation Guide.

Maintenance checks:
These simple actions will help to ensure energy use is kept to a minimum and systems operate effectively.

• Ensure that there is a sufficient amount of air flowing through each of the supply diffusers in the system.
• This Mechanical ventilation with heat recovery (MVHR) systems include air filters that must be inspected every 6 months and replaced at least every 12 months, if air filters are not changed regularly, they will become blocked, which will result in poor ventilation, increased electricity use and noise, and may shorten the life of the fans installed in the MVHR system.

Recommended maintenance schedule:
(see next page for the diagram).

• Remove the filter cover from the top of the unit (1).

• Take the used filters out of the unit (2/3) and dispose of them appropriately.

• Insert the new filters, ensuring that the printed arrows visible on the end of the filters are pointing downwards as per the diagram.

• Hold down the symbol on the controller for five seconds to reset the filter.

• Following this, the symbol will no longer be illuminated.

• ‘Call Environut on 01423 810 810.
  The filter part codes are:

  • FILTER-SK350-G4
