Operate the Bantam Holder as follows:
1. Close the drain valve.
2. Open the inlet valve one to two turns
and allow a couple of minutes for the
cartridge to fill. If leakage occurs at an o-
ring, close the inlet valve, loosen the
lower tightening wheel enough to rotate
the cartridge 90
°
, and retighten. Open
the inlet valve and recheck for leakage.
3. When water issues from the tubing,
adjust the inlet valve to the desired flow
rate (see
Cartridge Technical Character-
istics).
Purity Meter Operation
Operate the Direct Reading Meter by setting the
on/off switch to the “on” position. When the purity
meter drops below the acceptable minimum
purity, or when the purity meter needle registers
in the 0.05 to 0.025 megohm red range, the
cartridge should be replaced. The meter provides
a constant indication of the water purity. The
meter scale is calibrated 0 to 19 PPM (ionizable
impurities) with equivalent indications in
megohms resistance from 0.025 to 18, making
possible constant monitoring of the water purity.
To stop the meter from operating, set the on/off
switch to the “off” position.
Operation
Caution
Do not exceed a flow rate of 38
LPH (10 GPH). Leakage will occur if
this flow is exceeded.
Caution
Do not over-tighten the tightening
wheel.
