Important Notices
»Do not use alcohol, cleaning agents, spray lubricants, Rain-X,
or other solvents on the housing or lens port. Use of an
incompatible chemical compound can damage the plastic or
component o-rings, which may result in leaking.
»We recommend detaching the port from the housing and any
additional extensions during long periods of storage. Attach
the included neoprene covers to protect the dome from dust
and impact.
»DO NOT overtighten the Dome Shade Set Screws or you may
damage the shade. Overtightening is identied by bending
of the shade base away from the port around each set screw.
Slowly tighten the set screws so they just make contact in the
recessed areas and are snug against the port.

Attaching Your Dome Port and Shade
Attaching the Port to a Housing
1. The Dome Shade should be aligned and attached as shown. DO
NOT overtighten the Dome Shade Set Screws or you may damage
the shade. Overtightening is identied by bending of the shade
base away from the port around each set screw. Slowly tighten the
set screws so they just make contact in the recessed areas and are
snug against the port.
NOTE: Use 1/8” hex key (supplied with Ikelite Housing) to tighten
or loosen Dome Shade Set Screws.

2. Using your ngers or a 7/64” hex key (included), loosen each
Thumbscrew until at least 5 threads are visible.

3. Make sure the dome port sealing surface is clean and free of
debris.
4. Clean and lightly lubricate the o-ring. The o-ring needs to be
lubricated evenly until it is slightly shiny. Avoid dry spots or uneven
build-up of lubricant.
5. One of the three thumbscrews is positioned in the middle of a
larger projection on the dome shade. Align this thumbscrew with the
top center of the housing’s Port Mount (as shown).
6. Press the port rmly down until the base of the port is ush with
the Port Mount on the housing. If there is resistance, remove the
port and check that the thumbscrews are loosened and the o-ring is
properly lubricated.
7. Thumbscrews should align with corresponding Port Mount
Recesses. When each thumbscrew is tightened, the threaded end
of the thumbscrew tightens into the Port Mount Recess. When the
dome port is ush and seated properly onto the Port Mount, tighten
each thumbscrew until it stops.
DO NOT over-tighten.
Attaching the Port to an Extension
1. Using your ngers or a hex key, loosen each thumbscrew until at
least 5 threads are visible.
2. Make sure the dome port sealing surface is clean and free of
debris.
3. Clean and lightly lubricate the o-ring. The o-ring needs to be
lubricated evenly until it is slightly shiny. Avoid dry spots or uneven
build-up of lubricant.

4. Line up the thumbscrews on the dome port and extension. Firmly
press components together until they are ush around the
circumference.
5. Tighten each thumbscrew until it stops. DO NOT over-tighten.
6. Attach the complete dome port with extension to your housing,
Page 6.
Final Check
1. Submerge the housing with port attached in a fresh water tank
dedicated to underwater photography equipment.

9
2. Visually conrm that there are no signs of water intrusion. One sign
of water intrusion is a steady stream of bubbles coming from one of
the housing’s seals.
Maintenance
Post-Dive
1. Rinse the housing with dome port installed in fresh water.
2. NEVER leave your housing in the fresh water rinse tank. Collisions
with other peoples’ gear can cause scratches or damage to your
equipment.
3. Dry the dome with a clean micro ber lens cleaning cloth.
4. Attach the protective neoprene cover.
5. Stow the housing in a shaded place where it is protected from
impact or overheating. If no shade is available, we recommend
covering the housing with a towel or cloth.
Travel and Storage
1. Clean and dry the exterior of the dome port. DO NOT use any type
of glass or surface cleaner on the dome port.
2. Attach the protective front neoprene cover.
3. Store in a cool, dry place.
Scratches
Often scratches will ll in with water and become invisible in the
resulting image. Scratches are most likely to show up in your image
when shooting towards the sun or a light source.
Light scratches may be buffed out using NOVUS plastic polish,
available through Ikelite in single-use packets or bottles.

If scratches are too deep to polish out, the dome port can be returned
to Ikelite for replacement of the acrylic dome.
