Housing preparation Follow these steps to prepare your AD850 housing for use: STEP 1: Assemble your handle grips onto your housing using the provided screws (2) and Allen key. STEP 2: If you are adding any shoes, brackets or ball mounts onto your housing, mount them using the intended ¼-20 UNC threaded holes.
STEP 3: Mount your strobes and their arms onto the housing. For details about optical flash triggering and wired bulkheads, refer to the Accessories, Flash triggering section (page 25). Follow your strobe manufacturer manual and its recommendations. STEP 4: Before use, remove the main O-ring seal from its groove on the front half of the housing and carefully verify that the O-ring and its groove are free from scratches or foreign matter.

Housing closing STEP 1: Before closing the housing, remove the O-ring seal from its groove and carefully verify that the O-ring and its groove are free from scratches or foreign matter. Lubricate the O-ring with a light coat of silicone grease. Also check that the O-ring mating surface on the housing is clean and free of any physical damage.

STEP 6: Align the rear portion of the housing with the front one using the two guiding pins. STEP 7: Close the two housings shells together. STEP 8: Once both portions of the housing are pressed against each other, rotate latch towards the front until it catches the front hook, and then pull back until it locks into position.

WARNING: In the event that you should feel any unusual resistance when attempting to close your housing, do not force closure. Reopen and inspect carefully for any potential obstruction before trying again. STEP 10: Verify that both latches are locked by trying to pull them out without pressing the locking tab.
Housing opening NOTE: If your housing is under vacuum, you won’t be able to open it directly with the following procedure. See note in Accessories, Vacuum pump section. STEP 1: Unlock both latches by pressing the locking tabs and pulling them out. STEP 2: Rotate both latches to free them from the front hooks and pull out the rear portion.
Accessories Surveyor sensor Your AD850 housing comes standard with the Surveyor moisture alarm. This sensor device has two distinct purposes, a moisture detection circuitry and an ambient pressure sensor circuitry. NOTE: Once a battery is installed, the moisture detector function of the Surveyor alarm will remain on standby and does not need to be activated.

Moisture alarm mode LED code: LED is off Standby mode System is on standby Red LED flashing with audible alarm Water detected Water is making contact with probe If you want to benefit from the full capabilities of your Surveyor sensor, you can order the optional vacuum pump system (#19228).
Vacuum pump A vacuum pump will allow you to fully benefit from the capabilities of your Surveyor sensor. Your pump kit (either #19228 or #19233) includes the following parts: Vacuum pump Pressure valve Retaining nut Aquatica lubricant If your pump was not factory installed or bought separately, you will need to install the pressure valve bulkhead on your housing.
Page 24
While it is possible to mount your pump in the front 16mm port (#2), it is recommended to use the dedicated ½’’ port (#1). Using the front 16mm port will prevent you from using an external HDMI monitor bulkhead. To install your valve: STEP 1: Remove the existing plug by unscrewing the hexagonal nut inside.
Page 25
STEP 3: Remove the valve plug (#1) by sliding the quick-disconnect collar (#2). STEP 4: Insert the pump stem (#5) in the pressure valve and release the quick disconnect collar (#2). STEP 5: Make sure the pressure release plug (#6) is screwed all the way in (clockwise). STEP 6: Build vacuum inside your housing by pumping the handle (#7).
Nikonos-style bulkhead (#20084-NK and #20084-NK-VC) Ikelite-style bulkhead (#20084-KT and #20084-KT-VC) NOTE: Note that none of the offered flash triggering options on the AD850 housing are TTL compatible. For Nikonos and Ikelite style bulkheads, simply insert the velcroed board inside your camera hot-shoe.

If your housing is equipped with the optical flash option, you will need to use to provided slim flash trigger (#18940). STEP 1: Remove the battery tray (#2) from the flash trigger (#1). STEP 2: Insert the provided CR 2016-coin cell batteries (#3) inside the battery tray (#2).
Aqua View finder The AD850 housing is compatible with both the 180° Aqua View finder (#20054) and the 45° Aqua View finder (#20059). To install your Aqua View finder, you will have to remove the standard eyepiece. To remove your standard eyepiece: STEP 1: Using an O-ring removal tool, remove the eyepiece retaining O-ring (#1).
Page 29
To install your Aqua View finder: STEP 1: Carefully verify that the O-ring and its groove are free from scratches or foreign matter. Lubricate the O-ring with a light coat of silicone grease. Also check that the O-ring mating surface on the housing is clean and free of any physical damage. STEP 2: Insert your Aqua View finder inside your housing.
Care and maintenance With basic care and a regular maintenance schedule, your Aquatica housing will provide years of enjoyment and satisfaction in producing spectacular underwater images. Please follow all undermentioned care and maintenance instructions. Housing components After every salt water dive, soak and/or rinse your housing system in fresh water. It should soak for a minimum of 30 minutes.
O-rings When replacing the main seal O-ring, place the entire O-ring over the O-ring groove and start by pushing the O-ring in the corners. Work your way around the O-ring making sure it is snugly sitting in the groove. Avoid going solely in one direction as doing so will stretch the O-ring material and possibly prevent it from properly seating.
The internal O-rings of the housing are not user replaceable. While these O-rings are not as susceptible to damage as the main seal, rinsing the housing properly with fresh water to flush out salt crystals and sand residues will assure trouble free operation. Aquatica recommends yearly maintenance of the internal O-rings.
To obtain service during or after the warranty period you must notify Aquatica at +1 (514) 737-9481 and ship by registered mail (insured) only, enclosing your proof of purchase Aquatica Digital 3025 De Baene Montreal (Quebec) H4S 1K8 Mark clearly on your package “Canadian goods returned for repair”.
