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 may feature both round and hex style control glands. To
remove a control in a round style gland, Diagram J, page 22, 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 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, Diagram K, page 22.
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.
