2 Plan for the printer delivery truck
Read this section to obtain the information you need to make a successful coordinated delivery.
Special site access requirements
If your location will require security clearance for the printer delivery truck, you will need to work with the
trucking company to arrange security clearance before delivery is attempted.
Printer reception requirements
Identify the printer delivery location and receiving dock parameters, such as:
●Truck access and any truck size restrictions
●Available unloading space
●Delivery location (receiving dock) features to match delivery truck needs

NOTE: The printer should be kept indoors. If it is moved from a cold location, allow suicient time to acclimate
the printer to the installation site.
ENWW Special site access requirements 3

3 Plan for moving and uncrating the printer
This section will help you to determine whether the printer can be moved in the crate to the nal location, or
whether it will need to be uncrated and then rolled.
CAUTION: Unloading and moving the printer and all system components is your responsibility and not HP's.
Failure to provide the required moving and lifting equipment could result in personal injury or printer damage
during installation.
Moving equipment and personnel
NOTE: The printer should be uncrated as close to the installation location as possible.
●You may decide to hire a specialist mover, who should be familiar with your site and should read the moving
information in this guide.
●Ensure that you have the equipment needed to handle the crate: HP recommends a fork lift or pallet jack.
CAUTION: After the printer has been uncrated, do not attempt to move it with a fork lift or pallet jack,
which would damage the printer.
●The printer should be moved in the upright position at all times.
4 Chapter 3 Plan for moving and uncrating the printer ENWW

Moving the crated printer
Determine whether the printer crate can be moved to the nal location (see Printer crate dimensions and weight
on page 3). Check whether the dimensions of the doorways and hallways along the delivery path meet minimum
clearance requirements listed below.
With packaging
Minimum doorway width 1343 mm (52.87 in)
Minimum doorway height 2300 mm (90.55 in)
Space requirements for uncrating
Ensure that you have enough room to uncrate the printer.
NOTE: Measurements are approximate, and should be used as general guidelines only.
The oor space required for uncrating the printer is 2.4 × 5.9 m (7.9 × 19.4 ft), and the minimum ceiling height is
2.44 m (8 ft).
Uncrating the printer
Uncrating the printer will require a minimum of two people.
NOTE: The shipping crate comes with a ramp.
ENWW Moving the crated printer 5

4 Plan the printer production area and
environment
You are responsible for the preparation of the printer production area, which includes the following topics:
●Safety
●Printer space requirements
●Flooring considerations
●Environmental requirements
●Electrical requirements
Safety considerations
Fire-ghting equipment
You must provide two re extinguishers for the site. Make sure the extinguishers are placed where they are easily
accessible in case of re.
●A re extinguisher certied for electrical res must be in the print production area.
●A re extinguisher should be placed in the materials storage area, due to the large amount of combustible
dust (material).
Suitable materials for re-ghting include carbon dioxide, water spray, dry chemicals, and foam.
Emergency exits
Exit paths and rst-aid stations should also be considered.
Other equipment in the production area
Make sure that the printer is located in an area accessible by trained personnel only.
The printer is not intended for hazardous locations or ATEX-classied zones: ordinary locations only.
An ordinary location is a location that is not expected to have combustible dust clouds, and therefore it does not
need any specic protection against explosions. The opposite would be a hazardous location or ATEX-classied
zone, in which you can expect to nd combustible dust clouds, and which is therefore generally constructed to
resist explosions caused by an ignition source close to the dust clouds.
HP recommends that the recommended operation space be maintained. Additionally, the printer should be
protected against risks potentially created by other nearby installed equipment. That is, the printer can be
installed in the same room as other equipment, but it should be installed away from other equipment that could
potentially create a hazard during operation.
6 Chapter 4 Plan the printer production area and environment ENWW

When installing the printer in a room with other equipment, it is important to know whether the other equipment
requires an exclusion zone around it. If so, follow the manufacturer’s recommendations and material Safety Data
Sheets about how much space needs to be left around the equipment, and do not locate the printer inside that
exclusion zone. Follow your environmental, health, and safety processes and procedures.
The printer does not create combustible dust clouds during normal operation. Therefore, most equipment can be
installed following only the recommendations of both systems in terms of space needed. Some equipment can
create a hazardous or ATEX-classied location, so always check the documentation of your other equipment to
assess the potential risks, and decide what is the best setup for all of your systems.
Post-processing of parts
After printing the parts and removing the material in the processing station, you must clean the parts to remove
the thin layer of material attached to the surface. To do this, you need a bead-blasting machine. HP recommends
a bead-blasting machine with the following specications:
●Manual or automatic operation
●Air pressure in the range 2–5 bar (29–72.5 psi)
●Glass beads of diameter 210–297 μm (50–70 mesh)
Printer space requirements
Designing the optimal printing area
You will need a space of at least 2785 × 2530 × 2438 mm (109.6 × 99.6 × 96.0 in) to perform the following
tasks:
●Printing and printer maintenance (operation space)
●Servicing the printer and replacing components (service space)
Location of the network and electrical connections
ENWW Printer space requirements 7

Printer placement
Select the printer location carefully so that it will not need to be moved after it is installed. If possible, allow
additional space around the printer for service access.
IMPORTANT: If your printer needs to be moved even within the same room, you should contact your support
representative for assistance. The printer has been calibrated and leveled for optimum performance, and those
critical adjustments will need to be made again after the move.
Do not move the printer for any purpose without service assistance. Additional packing precautions and
installation calibrations are required for signicant displacements of the equipment.
Moving the uncrated printer
Read this section if you need to move the printer after uncrating.
The route between the unloading area of the printer and the installation site, including any corridors and
doorways through which the printer must be transported, is important to proper site preparation and should be
planned before the arrival of the printer. This pathway should be clear when the printer arrives.
Refer to the printer dimensions and weight table below, then review the doorway specications, do a thorough
review of the pathway identifying any equipment or furniture that needs to be removed, check for any narrow
doors, check whether any section of the ooring needs to be protected, and evaluate any threshold gaps
between rooms as well as any ramps over which the printer will be moved.
CAUTION: If you need to move the printer on its wheels to its nal position, move it down from the pallet but do
not remove all the transport protections and locks.
CAUTION: Unloading and moving the printer and all system components is your responsibility and not HP's.
Failure to provide the required moving and lifting equipment could result in personal injury or printer damage
during installation.

The muer accessory is recommended for installations in which the printer exhaust is vented into the room.
●Diverts hot air exhaust away from operators and adjacent surfaces
●Easy connection and disconnection with a simple hose clamp (included)
●Aesthetically pleasing all-black nish
●Reduces noise at the front (operating position) by 2 dB and by 5 dB at the back (near lamp exhaust duct)

●Dimensions: 510 mm × 186 mm × 127 mm (20.1 in × 7.3 in × 5 in)
●Weight: 1.24 kg (2.73 lb)
Ventilation
Adequate ventilation needs to be provided to ensure that potential airborne exposure to materials and agents is
adequately controlled according to their Safety Data Sheets. Consult the Safety Data Sheets available at
http://www.hp.com/go/msds to identify chemical ingredients of your consumables (material and agents).
You should provide a minimum of 6 ACH (air changes per hour) of fresh air ventilation and a minimum room
volume of 35 m³ (1236 ft³); or a minimum of 3 ACH plus an exhaust hood providing 4.25 m³/min (150 ft³/min)
over each installed unit. See Ducts and HVAC recommendation on page 48.
Take into account that personal protective equipment should be selected specically for the workplace,
depending on the concentration and quantity of hazardous substances. Technical measures and appropriate
working operations should be given priority over the use of personal protective equipment, in accordance with
local regulations.
NOTE: The ventilation units should not blow air directly onto the equipment.
ENWW Environmental specications and considerations 11

Ventilation should meet local environmental, health, and safety (EHS) guidelines and regulations.
Air conditioning
As with all equipment installations, to maintain operating conditions, air conditioning in the work area must
compensate for heat produced by the equipment. Typically, the printer's power dissipation is in the range of 4–6
kW (13.6–20.5 kBTU/h). If local exhaust is installed for the lamp outlet (air is ducted out of the room), the power
dissipation into the room decreases to 2.5 kW (8.5 kBTU/h).
Exhaust air temperature
The temperature of the air coming out of the printer may be up to 90°C (194°F) at the lamp exhaust duct, at sea
level. This should be considered when conguring your exhaust and HVAC system.
Typically, the printer's power dissipation without local exhaust is in the range of 4–6 kW (13.6–20.5 kBTU/h).
If local exhaust is installed for lamp outlet, the power dissipation into the room decreases to 2.5 kW (8.5 kBTU/h).
NOTE: Most of the hot air produced by the printer comes out of the top left, so that is where you should place
an extractor hood if you wish to use one, to avoid heating the whole room.
Material storage
Material storage, handling, and disposal should be performed as per local laws. See the Safety Data Sheets at
http://www.hp.com/go/msds for adequate handling and storage. Follow your Environmental Health and Safety
processes and procedures.
NOTE: Material and agent cartridges are designed to have an 18 month shelf life from the day they are
manufactured.
Electrical requirements
NOTE: Electrical requirements are not the same as for other HP Jet Fusion 3D printers; please review the
requirements carefully.
A certied electrician is required for the setup and conguration of the building’s electrical system as well as
connecting the power cable to the printer according to the electrical installation details in this guide.
It is the customer’s responsibility to make sure that the electrician is appropriately certied according to local
regulations, and to provide a copy of this document to the certied electrician who will validate and/or congure
the building’s electrical system used to power the printer to meet the printer’s electrical requirements and the
Electrical Code requirements of the local jurisdiction of the country where the equipment is installed.
NOTE: The printer is supplied without a power cable. Your electrician must provide a power cable that meets
the electrical requirements described in the power specications table.
12 Chapter 4 Plan the printer production area and environment ENWW

Using an external power supply or Uninterruptible Power Supply (UPS)
If you can ensure that the power network meets the specications constantly at all times of day, then it is not
necessary to install a UPS. However, if the voltage falls too low to provide good quality, the printer will show a
system error.
Although the specied input voltage is in the range 200–240 V, bear in mind that a variation of ±10% is allowed
for; so the minimum voltage accepted by the printer is 180 Vac.
If an external power supply or UPS is used, it is required that its input supply wires include one uninterrupted
copper ground wire (protective earth) from the main building service panel. This ground wire should run in the
same conduit and should be at least equal in size to the phase wires.
HP does not recommend a specic UPS for your printer. Should you decide to use a UPS in line with the input of
the printer, the UPS must be rated to meet the power requirements of the printer. It should be connected by a
certied electrician in accordance with the Electrical Code requirements of the local jurisdiction where the
equipment is installed. The customer accepts responsibility and liability for any damages or injury resulting from
the addition of a UPS.
Output power
The output power required from the external power supply depends on the number of printers to be powered.
For each printer, add 10 kVA to the output power.
Installing an external power supply
Install the external power supply following all instructions and recommendations provided by the manufacturer
of the power supply; and ensure that the installation is in accordance with the Electrical Code requirements of the
local jurisdiction of the country where the equipment is installed.
In order to facilitate normal operations and maintenance of the printer, HP strongly recommends installing the
external power supply with at least some separation from the printer.
Once the external power supply is installed and connected to the mains, ensure that the AC output of the power
supply is in accordance with the printer power, current, and voltage requirements described in the appropriate
power specications table below, before connecting it to the printer.

Example of a single-circuit connection to the building’s electrical system
The certied electrician needs to congure the proper wiring based on each specic country and building
installation, ensuring that it meets the voltage, current, and power requirements specied in the above table.
NOTE: The electrician must determine the appropriate circuit breakers, which are not shown in these schemes.
1. L1 wire
2. L2 wire
3. Protective earth wire
4. Jumpers (0360-3729 provided)
5. Circuit breaker
Circuit breaker (required)
The customer-provided circuit breaker must meet the requirements of the printer and should be in accordance
with the Electrical Code requirements of the local jurisdiction where the equipment is installed.
ENWW Electrical requirements 15

If the Electrical Code requirements of the local jurisdiction require an external RCCB or GFCI for earth fault
protection, install a device with sensitivity of 100 mA or higher, with appropriate rated current for the supply
conguration. Also ensure that other protective devices for earth fault protection upstream from the printer are
always greater than the one selected for the printer.
WARNING! Ensure that mains fault current is adequate for proper operation of the supplementary protection
incorporated in the equipment (5 kA rated interrupting capacity).
Power line disturbances
Reliable operation of your printer depends on the availability of relatively noise-free AC power.
●In order to ensure optimum performance and reliability, your printer should be protected from variations in
line voltage, which are common to production printing environments. Lighting, line faults, or the power
switching commonly found in machinery in factory environments can generate line transients that far
exceed the peak value of the applied voltage. If not reduced, these micro-second pulses can disrupt system
operation.
●If the power line supplying the installation site is a public low-voltage line shared with other users, the
power line impedance Zmax must be less than 80 mΩ, to comply with European standard EN/IEC
61000-3-12. If other users on the same power line report any ickering of incandescent light bulbs,
contact your electricity supplier to verify that the power network has an impedance lower than that
specied above.
●You are recommended to include overvoltage (OVP) and transient protection on the power supply to the
printer.
●All electrical noise-generating equipment, such as fans, uorescent lighting, and air-conditioning systems,
should be kept separate from the branch circuit used for your printer.
If you have power-quality issues when taking power from the grid, an external Uninterruptible Power Source
(UPS) can be used in order to meet the requirements of your conguration.
Electrical grounding
The printer must be connected to a good-quality, dedicated ground line (also known as a protective earth) in
order to avoid electrical risk. Note your obligation to comply with the National Electrical Code (NEC) in the country
of installation.
The following grounding tasks must be fullled to meet the site preparation requirements:
●Grounding wires should be insulated and at least equal in size to the phase conductors.
●Ground impedance should be less than 0.5 Ω.
●You should install a single point and dedicated ground.
Electrical installation details
The certied electrician will provide the following components:
●Power cable with appropriate specication (see power specications table below) and grounding ferrule
●Strain relief or grommet to install on the plate
●Drill and tool to make the hole in the plate
Additionally, the certied electrician will perform the following tasks:
1. Conrm that the main switch is in the OFF position.
