2.2. Step-by-step installation Find an appropriate area to place the device. Place the medical device (control unit) within the dental cabinet in a suitable position for your activity and leave enough free space to allow easy handling and proper aeration. Keep a minimum of 10 cm clearance around the unit. Do not stack it with other equipment. The medical device must be placed on a secure and flat surface (with a maximum slope of 5 degrees).

Check for proper water and air supply lines. Verify that your dental cabinet has a filtered tap water source and a compressed air source using air and water hoses EG-110 and EH-142, respectively. In case your cabinet water and air lines are not provided with the required hoses EG-110 and EH-142, a proper installation by qualified personnel is required. Call EMS Service for support. In order to prevent retro contamination, connect the cable to EN-1717 or DVGW 2 compliant fluid sources.

Check for a proper and safe power grid. This device uses a Class-I insulating system that requires protective earth. Plug the unit only into an FI protected mains supply (FI = Residual current protection). For USA and Canada: connect only to a hospital-grade outlet. Check that the rated voltage of the device is suited for the local line voltage to prevent damaging the unit, risk of fire and electric shock. The mains plug of the unit must be accessible at all times. DO NOT INSTALL the device in case your dental cabinet does NOT have protective earth. If you have any concerns about this, call EMS Service for on-site support by qualified personnel.

Be aware The use of cables and accessories other than those supplied by EMS may negatively affect EMC performance. Use only parts supplied by EMS. The device uses a low power radio, 8 dBm EIRP max, Bluetooth® 2.4 GHz, to communicate with the wireless pedal. Interference may occur in the vicinity of this equipment. The Bluetooth® radio is automatically disabled (powered off) when a wired pedal is connected. Portable RF communications equipment (including peripherals such as antenna cables and external antennas) should be used no closer than 30 cm (12 inches) to any part of the device, including cables. Otherwise, degradation of the performance of this equipment could result. 2
