Disposal
MELAG devices are synonymous with high quality and a long life-span. When you eventually need to decommission your
MELAG device, the required disposal of the device can take place with MELAG in Berlin.
Dispose of accessories and consumption media which you no longer require in the appropriate manner. Comply with all
relevant disposal specification in terms of possibly contaminated waste.
The packaging protects the device against transport damage. The packaging materials have been selected for their envi-
ronmentally-friendly disposability and can be recycled. Returning the packaging to the material flow reduces the amount
of waste and saves raw materials.

3 Description of the device
Intended use
The MELAdest65 water distiller enables the production of }distilled water. Water of drinking water quality is required as
a prerequisite, e.g. tap water. The device does not provide germ-free water. MELAdest65 is intended for use in the med-
ical field, e.g. in medical and dental practices and other medical care facilities outside the patient environment.
Functional principle
When the device is activated, the water temperature increases and escaping gases are boiled, then led through an open-
ing. The water temperature increases to 100°C and begins to boil. During evaporation, the chemicals, salts and soiling
remain in the container. The stream flows through the cooling coil system in the upper section where it cools and con-
denses into distilled water.
Scope of delivery
Please check the scope of delivery before setting up and connecting the device.

Fitting the glass flask
1. Remove the glass flask from the water distiller.
2. Remove all the individual parts from the glass flask carefully.
3. Remove the packaging from the individual parts.
4. Place the glass flask in the plastic guard ring.
5. Loosen a screw on the metal collar on the neck of the glass flask.
6. Align the metal collar in such a way that the other screw on the
collar lie exactly opposite the spout (pos.a).
a
7. Refasten the metal clip with the screw. Do not overtighten the
screws when tightening.
8. Fill the glass flask 3/4 full with warm tap water. Add 1-2 drops of
washing-up liquid and clean the inside of the glass flask.
9. Afterwards, rinse and clean the glass flask thoroughly with clear
water.
10. Place the cover (pos.b) on the glass flask in such a way that the
spout remains open.

11. Place the adapter cover (pos.c) and the spout cover (pos.d) on the
lid of the glass flask. If the covers are not needed, they can be
placed on the corresponding mounts.

12. Place the holder for the adapter cover (pos.e) on the grip end. For
safe storage during operation, the adapter cover can be placed on
the latching lugs (pos.f) of the holder.

13. Place the holder for spout cover (pos.g) from above onto the
holder for the adapter cover. The spout cover can be hooked onto
the rear end (pos.h) for safe storage during operation. In addition,
the holder fixes the cover of the glass flask to prevent it from
falling down.
Before commissioning
Checking the cover seal in the upper section of the distilling chamber
Before initial commissioning and every further use of the device, check the correct position of the cover seal in the upper
section of the distilling chamber. The seal may not present any uneven surfaces and must lay entirely flat. Otherwise,
boiling water could leave the upper section and e.g. flow onto the work surface. If the seal does not lie flat, press it on
with your hand. Do not use sharp-edged objects.

Cleaning the distilling chamber
Although the distilling chamber of the MELAdest65 has been cleaned with the greatest of care, manufacturing, packag-
ing and dispatch procedures could result in the presence of harmless residues of various substances. As a result, the
distilled water produced during initial commissioning could assume an undesired odour. To eliminate all odour-generating
factors, proceed as follows:
1. Set up the water distiller.
2. Remove the connection cable from the distilling chamber.
3. Remove the upper section of the distilling chamber.
4. Fill approx. 0.5l of tap water into the distilling chamber.
5. Put the upper section back on the distilling chamber.
6. Plug the connection cable into the socket on the distilling
chamber.
7. Place the glass flask (laterally rotated) without the adapter cover
under the distilling chamber discharge opening (pos.a).
a
8. Plug the plug into the socket.
9. Press the START/RESET button to activate the water distiller.
ÊThe ventilator motor begins to run.
ÊThe water distiller switches off automatically when no more
steam comes out of the discharge opening.
10. Pull out the power plug.
11. Empty the glass flask.
12. Wipe out the inside of the glass flask with a non-fuzzing cloth.
ÊThe distilling chamber is now flushed and ready for commissioning.

Producing distilled water
WARNING
Danger of scalding from escaping steam
The water is very hot. Steam can be emitted from the upper section and cause scalding.
nNever remove the upper section if the radiator motor is running.
nAllow the water distiller to cool for 30 min before removing the upper section.
Proceed as follows to produce distilled water:
1. Pull out the power plug.
2. Remove the connection cable from the distilling chamber socket.
3. Remove the upper section of the distilling chamber.
4. Fill the distilling chamber up to the upper marking with approx. 4 l
of tap water.
PLEASE NOTE: The use of hot water reduces the length of the
action.
5. Put the upper section back on the distilling chamber.
6. Plug the connection cable back into the distilling chamber socket.
PLEASE NOTE: Check the seal in the upper section of the
distilling chamber before each use. See Before commissioning
[}page9].
7. Place the glass flask (laterally rotated) under the distilling chamber
discharge opening (pos. a).
a
8. Plug the power plug into the socket.
9. Press the START/RESET button.
ÊThe ventilator motor in the upper section of the distilling
chamber starts.
ÊOnce the cycle has finished, the water distiller will switch off
automatically. The distilled water in the glass flask is ready to
use.
10. Close the side opening of the glass flask with the adapter cover.
11. Disconnect the power plug from the socket.
12. Allow the device to cool down for approx. 30min.
13. Dry the inside of the distilling chamber with a cloth to prevent
corrosion.
TIP: To check the }conductivity of the water produced (aqua dest), MELAG recommends the MELAtest 60 conductivity
meter.

Cleaning the distilling chamber
NOTICE
Danger of short circuit
If water comes into contact with the electric connections, this can result in the short-circuiting of the water
distiller.
nNever immerse the distillation chamber in water.
Interval Measure
before each use Checking the cover seal
Check the position of the seal for uneven surfaces. If the seal is uneven, press on it with your
hand. Do not use sharp-edged objects.
after each use Internal cleaning of the distilling chamber
Clean the inside of the distilling chamber with lukewarm tap water and a sponge to remove the
deposits from the distilling chamber. With persistent soiling / deposits on the inside walls, use
only a mild stainless steel cleaning medium, with a pH value between 5 and 8. Wipe out the
inside of the glass flask with a non-fuzzing cloth.
every 6 months Removing limescale deposits
Decalcify the inside of the distilling chamber when there are heavy limescale deposits or after 6
months at the latest. MELAG recommends the use of the MELAdest cleaning agent.

Glossary
Conductivity
is the ability of a conductive chemical substance or mixture
of substances to conduct or transfer energy or other sub-
stances or particles in space.
Distilled water
From the Latin aqua destillata; also referred to as aqua
dest; water which to a great extent is free from salts, or-
ganic material and micro-organisms, is produced from nor-
mal tap water or pre-cleaned water through the process of
distillation (evaporation and subsequent condensation).
Distilled water is used, for example, as feed water for
steam sterilizers.
