  • Page 57 8.4. SAFE INSTALLATION DISTANCES  All materials used at a distance less than 100 mm from the product must be non-flammable (do not burn, flame up, burn down) or only slightly flammable (do not burn, fall apart – e.g. plasterboard). These materials must not cover the inlet and outlet openings of the unit.
  • Page 58 8.5. POSITIONING AND SUPPORT  All units must be installed in the horizontal position. Any other position is prohibited.  The unit must be installed in such a way that the direction of the air inlet and outlets corresponds with the air circulation in the air distribution ductwork.
  • Page 59  Place the product in a horizontal position then tilt it about 3º towards the condensate connection (s) so that the condensate can easily drain away when in operation. Ceiling mounted products (HRFL2)  Products for ceiling void installation are equipped with pre-fitted hanging brackets and anti-vibration mounts. The integral brackets shall be used in conjunction with suitable threaded drop rods to facilitate lifting and levelling.
  • Page 60  The design of the ceiling must provide for access to the product for commissioning and maintenance of the equipment.  Discharge diffusers and plenum boxes should be supported independently from the ceiling. Return air grilles should not be positioned directly under the inlet of the product but located some distance away. They should ensure good air distribution throughout the room and that air at room temperature passes over return air temperature sensors (if fitted).
  • Page 61  Connections should be made using suitable clamps or clips ensuring that an airtight joint is achieved and the ductwork is then insulated and taped down. Ducting or connections smaller than the unit spigots should not be used.  It is recommended that shut-off dampers are installed in the atmospheric side to avoid drafts when the equipment is not in operation.
  • Page 62 8.7. NON DUCTED CONNECTIONS  If an opening of the unit is not connected to the ductwork, an metallic mesh in accordance with the Machinery Directive Requirements or similar protection must be used to avoid the contact with the fan, heating coils etc. ...
  • Page 63 8.8. OPTIONAL PRE HEATER COILS HRFL2/HR95  The unit can optionally be fitted with an electrical pre-heater manufactured with open coil heating elements and galvanized casing.  The heater is complete with fully modulating SCR (Silicon Controlled Rectifier) control (0-100%) and 2 stages of overheat protection (automatic and manual reset) all integral to the unit’s control strategy.
  • Page 64 HRFL2  The unit can optionally be fitted with an electrical post-heater manufactured with open coil heating elements and galvanized casing.  The heater is complete with fully modulating SCR (Silicon Controlled Rectifier) control (0-100%) and 2 stages of overheat protection (automatic and manual reset) all integral to the unit’s control strategy. ...
  • Page 65 8.10. PIPEWORK CONNECTIONS  To avoid strain on pipe joints from movement or vibrations, pipework should be connected to the unit as soon as possible.  Inlet and outlet connections shall be connected using suitable flexible hoses of the same size as the installation pipework.
  • Page 66 8.11. CONDENSATE REMOVAL  As long as there are conditions favourable for the creation of condensate ensure the unit condensate outlet (s) is connected to an appropriate water waste system.  Ensure the equipment is angled slightly (recommended 3 ) towards the condensate tray outlet spout to º...

    9. ELECTRICAL INSTALLATION 9.1. GENERAL  Mains power supply wiring to the unit units should be via a local switch isolator fitted no more than 1.5 meters away from the unit electrical/controls enclosure.  The isolator switch should have 3mm contact separation on both poles (‘live’ and ‘neutral’) and the unit must be earthed.
  • Page 69 9.2. MAINS POWER SUPPLY  The connecting terminals for the mains power supply cable is located inside the controls housing.  The minimum size of the protective grounding lead must be in compliance with local safety regulations for heavy current through the lead of the protective grounding of the device. ...
  • Page 70 HR85 Units  HR85-070 units are provided with a CEE 7/16 circuit breaker rather than a mains power switch (isolator). IMPORTANT: Minimum size of the protective grounding lead must be in compliance with local safety regulations for high current. For these reasons, units of 450, 550 and 750 size are provided with an additional grounding terminal located close to the electronics.
