Control Maintenance -
The Set Screw in the knob should be tightened down against the flat
area on the Control Shaft so the knob does not turn on the shaft.
Some of the controls have long shafts and feature a hex style control
-
gland. These controls can be pulled out, exposing the shaft, Diagram D,
page 25. To lubricate the control, gently pull on the knob until the
stainless steel shaft is exposed. Lightly lubricate the shaft, then move
the shaft in and out several times. This will lubricate the x-ring in the
Ikelite control gland. This should be done before using the housing after
a prolonged storage period, or once a week when the housing is in
constant use.
-
Some controls have a short shaft and cannot be pulled out exposing the
shaft for lubrication. To remove a control, Diagram E, page 25, loosen
the set screw in the knob (hex head wrench required); remove the knob.
If there is salt or dirt build-up on the exposed control shaft, clean the
shaft. Open the housing and gently slide the control shaft out of the
control gland. Clean and lightly lubricate the shaft, including the end of
the shaft. Slide the shaft back into the control gland and gently slide the
shaft back and forth a few times without fully removing the shaft from the
gland. Replace the knob noting the flat area on the shaft. The set screw
in the knob should tighten down against the flat area on the control, so
the knob does not turn on the shaft. Close housing without a camera
inside and water pressure test in a bathtub or swimming pool. Rotate*
the knobs to make sure the housing is watertight and the gland was
installed properly. Check all controls while the housing is submerged.
-
In the unlikely event one of the control shafts sticks or becomes difficult
to operate, you can remove the control from the housing and lubricate it,
or return the housing to Ikelite for maintenance.
*Caution: If your housing has a shutter spring, DO NOT rotate the
shutter control more than 1/16th of a rotation, otherwise, you may
accidentally bend the shutter spring or cause the spring to "pop off" the
control shaft.
