PREPARATION OF THE HOUSING
1. Attach Grip Bracket to the housing: The housing comes with two hand grips which should be installed on the
sides of the housing with the supplied screws and Allen key. Occasionally remove the grips and lubricate the screws
(see Care and Maintenance: of the housing.)
Depending on which strobe system you are using, you can mount the necessary shoes or brackets onto the 1/4"-20
threaded holes on the top of the hand grips. The AQUATICA TLC strobe arm system is recommended.
There are also 1/4"-20 threaded holes on the bottom of the housing that can be used for various mounting application
trays. As well there are two holes on top of the front half of the housing for mounting accessories.
Mount your strobes and connect the sync cord to the housing's flash bulkhead for the type of sync fitting you are
using. Be sure to read the section titled "Care and Maintenance: of the O-rings."
2. Lubricate the Main O-ring Seal: 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 the O-ring groove are free from scratches or foreign material.
Lubricate the O-ring with a light coat of silicone grease.
When replacing the 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 the O-ring is snugly sitting in the groove.
For proper handling and maintenance of O-rings be sure to read the section titled "Care and Maintenance: of the O-
rings."
PREPARATION OF THE PORTS
1. Select the correct port:
Depending on whether you've decided to shoot macro or wide angle photography, you will be installing either the flat
Macro Port; acrylic port (product # 18426), or glass port (product# 18427) or 8" Dome Port (Product # 18405) or 6”
Dome Port (product# 18406). See lens chart for the suggest port and accessories.
Macro Port Extension Rings: the Macro Port will accept the EF 50mm F: 2, 8 macro or Sigma 50 F: 2.8 macro. If
you intend to use a longer lens such as the Canon EF 100mm F: 2.8 macro or the Sigma EX 105 F: 2.8 macro, you
will require # 18453 extension ring. These extension rings fit between the Macro Port and the housing to provide the
extra space necessary for the longer lens.
Dome Port Extension Rings: When using a wide angle or zoom lens, the Dome Port should be used with an
Extension Ring as follows: Refer to the Lens Chart on www.aquatica.ca for updating of lenses that can be used in the
housing.
These extension rings fit between the housing body and the Dome port to provide the optical correction needed for
each lens.
In order to reduce glare, maximize contrast and offer physical protection to the dome, the use of a dome shade
(product # 18480 for fisheye shade, and #18482 for wide angle shade) for the 8” dome or #18482 Fisheye or 18482
wide angle shade are recommended.
2. Clean the port:
Dirt, grease or fingerprints on the port especially on the inside, can adversely affect the quality of the image. Acrylic
ports should be cleaned with plastic cleaner and the glass ports should be cleaned with lens cleaner. For more details
make sure to read the section titled "Care and Maintenance: of the Ports."
3. Lubricate the port O-ring seal:
Before using the port, remove the O-ring on the rear of the port and lightly coat it with silicone grease. For more
details refer the section titled "Care and Maintenance: of the O-rings."
