Operations - DOSMATIC MiniDos Serie Manual De Operación

Clicking Sound is Normal
Fluid lowing through the injector will automatically cause
the injector to "click" and inject a set amount of solution
into the luid line. The higher the low rate the more frequent
the "clicking". The injector is designed to inject solution
proportionally (at the same set ratio) regardless of luid low.
Service Fluid Flow
Fluid low and pressure must be within the established
speciications (see Speciication on page 6) for your model.
Change Feed (Injection) Rate
The feed rate on the injector is adjustable EVEN WHILE
OPERATING AND UNDER PRESSURE. To change feed rate see
Fig 1 (a, b or c) and Fig 2 (a, b or c) based on your injection
rate. Do not remove #79 when injector is under pressure.
MiniDos 0.4%, 1%, 2.5% and 5%, see Fig 1a and 2a
Rotate Ratio Adjuster (#61) (Fig 1a) up or down using the
Setting Indicator Mark (Fig 2a) to select the desired feed rate.
MiniDos 10%, see Fig 1b and 2b
1. Remove Interlock Pin (#65) (Fig 1b.).
2. Rotate Ratio Adjuster (#61) up or down to the desired
setting. Use the top of the Ratio Adjuster Sleeve to line up with
the desired feed rate setting (Fig 2b).
3. Re-insert Upper Interlock Pin (#65). Clip must be parallel
with settings to be able to re-insert.
MiniDos 20%, see Fig 1c and 2c
1. Remove Ratio Locking Pin (#79) (Fig 1c.).
2. Rotate Outer Cylinder (#7) up or down to the desired setting.
Use the top of the Outer Cylinder to line up with the desired
feed rate setting (Fig 2c).

NOTE: Do not adjust feed rate below lowest setting line.
Measure outlet luid to assure desired feed rate is being delivered

Bypass Operation
Injecting solution into the luid line can be TEMPORARILY
stopped with the On/Off feature (Fig. 3). Moving the
On/Off Lever to the OFF position allows service luid to
pass through the injector without injecting chemical. No
"clicking" will be heard.
With the On/Off lever set to the ON position the injector
will operate as normal and "clicking" will be heard when
luid is lowing. It is recommended to use the three-valve
bypass (see Fig. 5), for continued bypassing or servicing
of the injector.
