Safety
Read and understand these instructions carefully before beginning installation. The unit should only be installed by a competent person.

Electrical Connection
The unit requires a continuous electrical power supply. Connection to the fixed wiring must be made outside the unit in a suitable location. The unit must be able to be disconnected from the main supply after installation. The unit must be earthed and a double pole switch having a minimum contact separation of 3.0mm must be used to provide isolation for the unit.

The power cable running into the unit must remain the supplied flexible cable (not a solid core lighting cable]. If the power cable becomes damaged, it must be replaced by EnviroVent, an authorized service agent for your region/country, or a similarly qualified person to avoid a hazard. Do not remove or tamper with any electronic components inside the unit.

All wiring must comply with Building Regulations and the current IET Wiring Regulations (BS7671 in the UK) or equivalent standards for other countries. The final installation should be examined and tested by a qualified electrician.
This product is not suitable for use with a Type AC RCD.

Location

Check there is space for the unit in your chosen location including room for access and future servicing of the unit. The unit must not affect the operation of open-flue appliances. Consider the external vent locations for open flames from appliances e.g. boilers. You must ensure the external supply grilles are positioned away from open flues to avoid drawing harmful gases into the property. Consult your local regulations or a qualified gas engineer. Envirovent recommends at least 2m clearance.

Users
This unit is not intended for use by persons [including children] with reduced physical, sensory, or mental capabilities or lack of experience and knowledge unless they have been given supervision and usage instruction by a person responsible for their safety. Children should be supervised to ensure they do not play with the unit. Cleaning and user maintenance must not be performed by children.

Diagrams

Overall unit dimensions and minimum area required for access & maintenance (mm). The local isolator must be connected to the mains as part of the fixed wiring. Connect the cores of the power cable to the matching terminals on the local isolator (3A fuse spur or similar). The black switch live core of the mains cable can be wired to a switch input such as a light switch. When the switch is turned on, the boost function is engaged. When the switch is turned off, the unit will return to normal running mode. In this configuration, a triple pole isolator must be used.

About the energiSava® 200
The energiSava® 200 is an MVHR unit (Mechanical Ventilation with Heat Recovery). It is ideal for small to medium-sized properties with a kitchen and up to 5 additional wet rooms. The unit is capable of delivering a maximum airflow of 245m3 /h (68l/s) and a maximum system pressure of over 500Pa.

The unit will help to create a fresh and healthy living environment by supplying filtered air into a property through supply valves. Moist, stale air is removed from the property through extract valves. The heat exchanger inside the unit transfers waste heat energy from the extracted air to the supplied air to improve the thermal efficiency of the property and reduce heating costs. When outdoor temperatures are low, the frost protection feature automatically reduces the supply air flow rate to ensure the heat exchanger inside the unit does not freeze.

The Intellitrac® humidity tracking function monitors the humidity levels in the extracted air and will automatically increase the supply and extract air flow rates when the humidity levels rise. Once the humidity levels are lower the air flow rates will return to the normal rate. The automatic, mechanical bypass helps to control the temperature entering the home on warmer days. The energiSava® 200 includes a switch live function. When wired through the lighting switch of a room (such as a bathroom) the unit will enter boost mode whenever the light is turned on.
