Control Maintenance -
continued
- 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.
Your housing features both
round
and
hex
style control glands. To
remove a control in a
round
style gland,

,
page 24
, loosen
the set screw in the knob (allen 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 and o-rings, including the
large end of the shaft.
If there is a shutter spring on the Control Shaft, make sure it is in its
proper position. Rotate the Shaft back and forth slightly to aid installation
back into the Control Gland.
Replace the knob with the Set Screw over the Control Flat. 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,

.
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.
