Section 3: Maintenance
3.1 Normal conditions
Under normal measurement conditions, Daniel recommends lubricating the slide valve and
exercising several key components of the Daniel Senior Orifice Fitting every thirty days (refer to
Section 3.1.2: Component Exercise ). If the plate changing operations are performed within this
period, omit this operation.
3.1.1 Lubrication
Important
The information in this section, “3.1.1 Lubrication”, DOES NOT apply to Seniors equipped with
Soft Seat slide valves.
In order to perform the maintenance operation described in this section, the following
maintenance check list must be met first:
• The slide valve must be in the “CLOSED” position.
• The Bleeder Valve (10B) must be in the “OPEN” position.
• The Equalizer Valve (1) must be in the “CLOSED” position.
• The Senior must contain 100 psig minimum line pressure.
PRESSURIZED FLUID HAZARD
When opening the bleeder valve (10B) or venting the Top (14) thru the bleeder valve (10B),
direct the released pressurized fluid and/or gas to safe area away from any individual in
accordance with local environment regulations.
The bleeder valve (10B) releases pressurized fluid that may cause contamination and/or
accumulation of volatile gas mixtures. Failure to do so may cause serious injury or death.
