3 ABOUT THE UNIT The is a whole house heat recovery unit which works by continuously extracting stale, moisture-laden air from the Wet Rooms of the apartment or a house - the kitchen, bathroom and en-suite rooms - and ducts this to a central unit. This extracted air passes through a high efficiency counterflow heat exchanger before being ducted to the outside. Fresh air is drawn into the unit from outside, which is warmed by the heat exchange cell and delivered into the living, dining and bedroom areas.

4 INSTALLATION INSTRUCTIONS IMPORTANT Be sure to have read and understood these instructions before beginning the installation process. PRE-INSTALLATION CHECK LIST Make sure that the unit can physically fit in to the desired location. The unit should be situated so that access for maintenance or replacement of parts is possible. Make the ductwork runs as short as possible. Having the most direct route and using as few bends as possible will reduce air resistance and improve the efficiency of the unit. SAFETY AND RECOMMENDATIONS All wiring must comply with Building Regulations and the current I.E.E. Wiring Regulations (BS7671) or the equivalent standards for your country. The final installation should be examined and tested by a qualified electrician. Precautions must be taken to avoid the backflow of gases into the dwelling from the open flue of gas or other fuel-burning appliances. Make sure the mains supply complies with the rating label for voltage, frequency and phase. This appliance 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 or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.

5 INSTALLATION INSTRUCTIONS FIRST FIX - Installing ductwork and electrical supply 1. Locate external terminations (supply and extract) in accordance with the latest addition of the Domestic Ventilation Compliance Guide. 2. Ductwork within house Ø125mm - maximise duct size where possible. Make sure that the ductwork is insulated in unheated spaces. Minimise flexible duct. 3. Locate the mains supply within 1m of the location of unit. The position of the electrical power supply or unit (a fused switched isolator) must not be mounted above or closer than 1m to a cooker where it could be affected by excessive heat or moisture. 4. Make sure that there is room for the MVHR unit. The unit is designed to be vertically mounted in a kitchen or utility cupboard (on the wall). It can also be floor mounted in a loft space with an additional drainage kit. EnviroVent Part number KIT-CONDENSATE-ES Also make sure that there is a free space at the front of the appliance for cleaning the filter and carrying out maintenance on the appliance. Ducting Configuration See page 7 for duct connections to the unit/airflow directions Installed example, RH unit shown.

6 INSTALLATION INSTRUCTIONS SECOND FIX - Installing the unit 1. Fixing the unit. 3. Carefully remove the top foam moulding by pulling it straight forward. Foam mouldings must remain parallel. Take care not to damage the sealing gaskets. 2. Remove the front cover...held on with Velcro pads. Do not pull from one edge as this may damage the internal fixing rods. Laying the unit down on a stable surface remove retaining screws and washers x 4, store safely.

7 INSTALLATION INSTRUCTIONS SECOND FIX - Installing the unit 4. Fixing the unit. 6. Fix the mounting plate to the wall or joists with supplied fixings mounts and plugs Remove mounting rods and washers x4, store safely. Ensure that there is enough space for the condensate drain to be fitted and ducts to be connected. 4 tilt recommended. 7. Reassemble the case assembly unit to the mounting plate. Steps 5 and Prepare the drain. All MVHR units produce condensate. The condensation drain should be located at the lowest point in the foam moulding as shown overleaf. The drain can also be prepared before the case assembly is mounted. Stand the unit upright on a stable surface and carefully separate the case assembly from the back plate, leaving the fixing rods attached. Pull out the heat cell and decide drain location, see next page.

10 COMMISSIONING Electrical connections The appliance must be earthed. All wiring must completed by a qualified electrician. This appliance is suitable for 230v ~ 50Hz single phase supply fused at 3 amps. The appliance is supplied with a mains flexible cable (PVC sheathed, 6-core blue 1, yellow 2, white 3, green 4, black 5, and red 6) See next page. A double pole switch having a minimum contact separation of 3.0mm must be used to provide isolation for the unit. Typical settings It is recommended that Low (R1) is set as the base or trickle rate. Medium (R2) and High (R3) may be set as required. Unit airflow rates must meet Building Regulations Approved Document F. Settings must be recorded at commissioning for future reference. See page 11 for how to commission an MVHR Unit The fan speed control must not be mounted above or closer to 1m to the cooker where it could be affected by excessive heat or moisture. Fan speed controllers are supplied separately. Switch Positions Low (R1) Medium (R2) High (R3) Function 100% adjustable 100% adjustable 100% adjustable Remote Switch Positions (R4) (R5) 100% adjustable 100% adjustable

11 COMMISSIONING Wiring diagram Typical settings The adjustment panel can be found inside the control box. The potentiometer s range of movement is 270. Use an appropriately sized screwdriver to alter the potentiometer. Commissioning adjustments made to R1, R2, R3 affect both supply and extract fans simultaneously. See Pg 11 for how to commission an MVHR Unit.

12 COMMISSIONING Commissioning of a continuous running ventilation system - MVHR Commissioning of the system is necessary to provide adequate ventilation to the dwelling, as stipulated in Approved Document F (ADF) of the Building Regulations* Conditions All maintenance and development works should be completed prior to the commissioning of the unit, this is to avoid high levels of dust being drawn into the system and general disturbance to the setup. The unit should only be commissioned when fully installed, with power, ductwork, valves and vents in place. See Domestic Ventilation Compliance Guide. Equipment required Anemometer which is capable of measuring l/s or m³/hr. Commissioning method Once the previous conditions are met, High and Low rates need to be set. These should be set as outlined in the commissioning guide (page 10). Extract and Supply (Flow rates should be balanced on boost and trickle) Commissioning guide Boost rate (minimum high rate) Determine the whole building ventilation rate. See ADF of the Building Regulations. Open ceiling/wall valves. Measure all extract points summing the individual room rates. Measurements to be carried out with an appropriate anemometer. Adjust using fan speed using R1, R2, R3 until the total extract rate is met. See the individual product s instruction guide for method (page 10). When the desired overall rate is achieved, the individual valves should then be adjusted to draw the appropriate volume of air from each room, typically starting with the largest extract requirement first: kitchen, bathroom, utility room, en-suite and WC. It may be necessary to adjust the fan unit slightly to account for increased pressure. When adjustments are completed the valves should be locked into position to maintain settings. Trickle rate This should be set around about 75% of the Boost rate. See ADF of the Building Regulations. As the valves have been commissioned at high they will not need to be altered further, the Low rate should be adjusted up or down, until the lower extract rate is met. See the individual product s instruction guide for method on page 10. For guidance on good installation practice for MVHR systems see the latest edition of the latest edition of the Domestic Ventilation Compliance Guide*. This guide provides in depth information on all aspects installation, inspection, testing and commissioning. * Applicable in England and Wales. For other countries please refer to your local building regulations.
