Cleaning
For top performance and efficiency, the MEGA-PURE One
Liter Water Still should be kept clean and free of scale. It is
recommended that the boiler be drained and refilled with
fresh water daily to flush the boiler of the concentration of
contaminants from the previous day’s run.
When using untreated boiler feed, cleaning is recommend-
ed after every 15-20 hours of operation. The unit should be
cleaned with a hydrochloric acid solution. This is done as fol-
lows:
1.
Push unit “OFF” switch.
2.
Disconnect output tubing at condenser "B" from
collection vessel and temporarily place a beaker
under condenser outlet.
3.
Drain boiler by opening clamp "G." Close clamp
"G" after boiler has completely drained. Refill boil-
er.
4.
Use the spare pinch clamp from the parts box to
shut off overflow tube from constant level chamber
"K" as close as possible to overflow stem.
5.
Carefully pour approximately 260 ml. of 10%
hydrochloric acid solution into top of constant level
chamber "K."
6.
Wait approximately 10 minutes or until residue dis-
appears. If additional cleaning is required, drain
boiler down 1 inch and turn unit on for a few min-
utes until residue disappears. Do not boil. Turn the
still off.
7.
Carefully drain the unit, remove clamp from over-
flow tube and refill with fresh water. Drain boiler,
refill with fresh water and operate for 30 minutes.
Reconnect tubing from collection vessel to con-
denser "B."
