-4 helm pumps are fitted with positionable O-ring style hose fitting
ports (referred throughout this manual as ORB). -4 ttings are
exactly the same as -3 ttings. Do NOT attempt to install an NPT
pipe fitting into a -4 helm hose fitting port. Doing so will lead to
irreparable damage to the helm. ONLY use Dometic O-ring style
hose fittings (ORB).
WARNING
Failure to properly tighten the
lock-nut (item 1) may lead to
loss of steering control. Loss of
steering control may result in
unpredictable boat behavior,
collision with an obstacle and/
or ejection from
vessel, leading
to property damage,
personal
injury and/or death.
Dometic recommends that the hose and hose fittings are checked on
a regular basis to ensure the safe operation of the steering system.
