Instructions
1. Make certain that installation of the DWM-20A model complies with all federal, state and local laws and regulations
as well as with your building codes, office/apartment or condo provisions, rules or regulations.
2. In the installation of DWM-20A you must only use HS-5441 filtration system. The Manufacturer is not responsible
for any misuse or modification of HS-5441 filtration system and accepts NO liabilities if the DWM-20A is used with
different filtration systems. In addition, the use of non original filters invalidates the Manufacturer
3. on the DWM-20A water dispenser.
4. Do not connect the DWM-20A dispenser and its filtration system to a water supply that is microbiologically unsafe
or of unknown quality without adequate pre-treatment and disinfection. Connect HS-5441 filtration system to the
city potable water only.
5. If the DWM-20A is left unused for more than 3 days, dispense at least one bottle of water from each water type. If
left unattended for more than 30 days, replacement of its filtration system and of its alkaline chamber is
recommended before starting to use the DWM-20A again.
6. The DWM-20A dispenser must be connected to a cold water supply with a pressure of at least 45 psi measured
on a 3/8” section tube. A very low external water pressure (at or below 40 psi) or a very low water flow rate (below
1 gallon/minute) will significantly reduce or hamper the performance of the DWM-20A and its ability to properly
carbonated sparkling water. If the water pressure is low, please use the booster pump as indicated in the Parts
Manual (order separately).
7. The DWM-20A is designed to operate up to the maximum allowed water pressure for a residence or a commercial
building, which is 80 psi (552 kPa). However, the recommended maximum water pressure is 60-65 psi. To reduce
the water pressure, use the water pressure regulator provided in the installation kit.
8. Do not use the DWM-20A outdoors. The recommended room temperature, for indoor use, is comprised between
41°F and 90°F.
9. When the filtration system indicator (green light – top right) starts blinking (on/off) it means that the HS-5441 filters
and the HS-5442 alkaline chamber have reached the end of their lifespan, and MUST be changed in order to
prevent quality deterioration of your drinking water and/or clogging of the system. It is recommended to replace
the HS-5441 filters and the HS-5442 alkaline chamber as soon as possible when the green light indicator starts
blinking or every 6 months, whichever comes first.
DUE TO THE FACT THAT THE MANUFACTURER MAY NOT KNOW THE QUALITY AND THE
PERFORMANCE CHARACTERISITCS OF ANY POSSIBLE ALTERNATIVE FILTRATION SYSTEMS IN THE
MARKET, PLEASE NOTE THAT THE MANUFACTURING WARRANTY OF THIS DISPENSER BECOMES
NULL AND VOID SHOULD YOU USE FILTER(S) OTHER THAN THE HS-5441.
