DO NOT apply any type of petroleum-based lubricant, such
as household oil or motor oil to any part of the SEA-4500.
The SEA-4500 does not require any lubrication under normal
circumstances, except that which is performed during annual
inspection and service by a factory trained service technician.
DO NOT apply any type of aerosol spray to the SEA-4500. Doing
so may cause permanent damage to certain plastic components,
including the second stage housing.
During training exercises, it is important to ensure that the SEA-4500
is always pressurized whenever it is submerged in order to prevent
the entrance of water into the system. Whenever the system has been
completely emptied of air underwater, it is important to return the
SEA-4500 as soon as possible to a qualified technician for visual
inspection and any necessary service before attempting to refill it.
It is important to fill the SEA-4500 only with dry, filtered air with
a water vapor content that does not exceed -65°F / -53ºC dew
point. Excess water vapor in the air can cause ice to form inside
the SEA-4500 and interfere with the operation of the system at
colder temperatures.
