4210 Flow Meter
Section 3 Installation
This section of the manual tells you how to install the 4210 Flow
Meter. There is also information on mounting methods, intercon-
nection wiring, and the setup procedure.
3.1 Preparation for Use Isco ships the flow meter with a roll of paper installed and a
default program entered into memory. You should familiarize
yourself with the programming procedure and practice working
through the program steps, so you become comfortable with pro-
gramming the unit. With the exception of setting the level, you
can program the unit in the shop, rather than on the job site, if
you want. This is a good idea as it will minimize the possibility of
dirt and contamination getting inside the flow meter.
3.1.1 Opening the Case To access the flow meter keypad and internal plotter, you must
open the case. Do this by unlatching the two catches on the right
side of the flow meter cabinet (as you face it) and opening the lid.
Keep the flow meter lid closed and latched whenever possible.
This will protect the internal components from dirt and moisture,
and will prolong the life of the desiccator.
3.1.2 Desiccant Canister
Installation
If the unit is new, at this time you should install the desiccant
canister. It is provided in the accessory package and looks like a
small, flat can with little holes in it. Open the flow meter case lid.
Note the small clamp that resembles a bottle cap opener located
near the bottom right-hand corner of the case lid. Install the des-
iccant canister by pressing it under this bracket, with its viewing
window lined up with the circular hole in the bracket. Make sure
the clamp is fully engaged over the canister. The particles inside
the desiccant window should be blue. If the particles are pink,
the desiccant is saturated and you will need to regenerate the
canister before using it. If the unit has been in use and has been
returned for reprogramming, you should clean it and inspect it as
outlined in Section 5 of this manual.
CAUTION
Do not operate the flow meter with a saturated desiccant can-
ister or with the door left open. Dust and moisture will settle
inside and cause damage that can eventually damage the unit
seriously. For maximum equipment life, inspect the desiccant
canister regularly and regenerate it when necessary. Keep the
lid closed and latched unless you are programming or servic-
ing the flow meter.
