Follow the ventilation recommendations in the site preparation guide. NOTE: The ventilation units should not blow air directly onto the printer. Air conditioning As with all printer installations, to maintain ambient comfort levels, air conditioning in the work area should take into account that the printer produces heat. Typically, the printer's power dissipation is in the range of 4-6 kW (13.6-20.5 kBTU/h). Air conditioning should meet local environmental, health, and safety (EHS) guidelines and regulations. NOTE: The air conditioning units should not blow air directly onto the printer. An HVAC unit is required which can consistently maintain the recommended operating temperature in order to achieve optimal printing performance. More specific technical information can be found in the site preparation guide. Sound pressure level The HP VCVRA-1804 maximum A-weighted sound pressure level over bystander positions while printing is 80 dB(A). Hearing protection may be required as per local laws; consult your EHS specialist. Printer transport hazard Special care must be taken to avoid personal injury when moving the printer. ● Move the printer over smooth, flat surfaces without steps. ● Move with care and avoid shocks during transport, which could spill the material. ● Lock the front casters when not moving the printer. Remember to unlock them before moving it. If you move the printer between different rooms, bear in mind that it should be kept in constant environmental conditions, and recalibrated when it reaches its new location: recalibrate the load cells, check the spacing between the spreader roller and the preheat plate, and check printhead alignment, realigning if necessary. 3D part retrieval Wear heat-resistant gloves when retrieving 3D printed parts manually. Safety gloves are also recommended when retrieving 3D printed parts after auto-extraction, as the parts may still be hot. Personal protective equipment HP recommends the following equipment, which may be used for material handling and certain maintenance and cleaning tasks: 1. A pair of heat-resistant gloves per person. 2. Conductive or electrostatic-dissipative footwear and clothing. 10 Chapter 2 Safety precautions
