from beginning to end. Once you are familiar with your ROV, you can use it as a
reference or to refresh your memory.
This document covers:
General safety information
Components of the ROV system
How-to guides for ROV operations including testing and field use
Tips and tricks to get the best out of your ROV
Storage instructions
Approved maintenance instructions
Guidelines for packing and travelling with the ROV/sending the ROV by third
party freight
Troubleshooting tips
Appendices with more detailed specifications of ROV components.
3.1 Other Luna documents
Battery safety information and instructions
This document does NOT cover any instructions or safety information relating
to the Lithium Polymer (LiPo) batteries used in your ROV battery pack. For this
information you must read our Boxfish Battery Charging Manual. (latest version
available on our website: https://www.boxfish.nz/downloads/.
Camera control
This document does not describe how to take video or still images with the
Luna. We have created a separate manual, the Boxfish Luna Camera
Operations Manual with all information related to shooting video and photos.
3.2 IMPORTANT and WARNING messages
Throughout this document you will see the following messages:
IMPORTANT!
Important notices draw your attention to things you must do (or must not
do) so that you don’t BREAK OR DAMAGE the ROV or its accessories.

Boxfish Luna Owner’s Manual
p9 R7. All rights reserved. Information and specifications may change at any time without notice.
WARNING!
Warnings are for your SAFETY so that you don’t CAUSE INJURY
to yourself, any other operators of the ROV, or people nearby.
LiPo BATTERY WARNING!
Warnings for SAFETY so that INJURY or DAMAGE does not
occur when dealing with the Lithium Polymer (LiPo) batteries in
Boxfish ROV battery packs.
If not treated according to our instructions, LiPo batteries could
leak corrosive substances, emit toxic gases, catch fire or
explode.

4 Important safety information
Please follow the information in this section closely to prevent injury, damage,
or violation of your warranty conditions (available in our Terms of Sale at
https://www.boxfish.nz/support/terms-conditions/).
4.1 Battery safety, maintenance, storage and disposal
The ROV uses Lithium Polymer (LiPo) batteries in its battery pack.
Please refer to our Boxfish Battery Charging Manual. (latest version available
on our website: https://www.boxfish.nz/downloads/.
4.2 Lifting ROV components
The ROV, Accessories Box (with Control Station inside) and larger tether
reels (>1.2km version) require two people to lift. Take care when lifting.
The ROV can only be safely lifted by the stainless-steel bumper/protection
bars, carbon fibre frame tubes, or the lifting eye on top.
4.3 Hazards
Take extreme care around deep water and potential slip hazards when
piloting and retrieving the ROV.
Plan your operations to minimize trip hazards from the ROV system,
especially the tether and cables.
LiPo BATTERY WARNING!
You must read the Boxfish Battery Charging Manual and follow
the instructions carefully. Misuse of the Boxfish ROV lithium
battery pack may cause a battery fire and/or explosion.

Boxfish Luna Owner’s Manual
p11 R7. All rights reserved. Information and specifications may change at any time without notice.
Never operate the ROV in the presence of unaware swimmers or other
vessels.
Supervise children and keep them well away when ROV is operating.
While ROV is running pay close attention to the thrusters. Do not touch the
thrusters any time the ROV is powered on, or serious injury may occur. Keep
fingers, long hair and loose clothing or anything that may become entangled
well clear of the thrusters when operating.
The ROV should not be operated close to any object which may get caught
in the thrusters.
DO NOT look directly into the ROV LED illumination lights when they are
turned on.
DO NOT look directly into the ROV scaling lasers (if supplied). The scaling
lasers emit Class 3R laser light. Laser protective eye wear is normally not
necessary. A Class 3R laser is not a skin or materials burn hazard.
DO NOT look directly into fibre optic cables, or fibre optic ports on the ROV,
tether reel or Control Station while the ROV or Control Station is operating.
The lasers used to transmit the signal is invisible but can cause damage to
the retina of the eye. The below stickers are present on these ports to
remind you.
4.4 Safe ROV operation
The Boxfish Luna takes at least two people to operate: one person to pilot
the ROV and one person to manage the tether cable.
DO NOT use the ROV below its depth rating: check the rating specified in
your order or contact us if you are unsure. Some domes have different depth
ratings to the ROV – check with us if you are unsure.
DO NOT operate in currents where control is impeded.
DO NOT operate outside the water temperature range of -10˚C to +45˚C.
DO NOT store the ROV outside the range of -20˚C to +70˚C.

Each component of your Boxfish Luna system will be stored in a black
waterproof Pelican case. A typical Luna system is shown below.
ROV case
(left)
ROV case. Includes the Boxfish Luna ROV.
Tether case
(middle)
Includes tether reel and cable. Winder handle and

to 15.6V This will prevent the battery from draining completely and will
prolong the life of the battery and protect the components inside the ROV.
See our Boxfish Battery Charging Manual for instructions.
IMPORTANT! The Control Station must be stored inside the Accessory
Box case for protection.
