MODwater DWM-20A installation. The following parts are included with your MODwater DWM-20A.
Tools that are not included but are needed to complete the installation are as follows; tube
cutter, screw driver, tongue and groove pliers, and adjustable wrench. Step one, key dimensions
and clearances for the MODwater. Be sure to allow at least 4 inches of space at the rear and sides
for proper ventilation. Place the unit in its permanent position, it's important not to move it
after activation. Also, if unit was tilted or turned upside down during transportation or unpacking,
allow to sit for 2 hours before turning on. Install angle stop valve on main water supply within 10
feet of the MODwater unit. Minimum water pressure for proper operation is 45 psi. The DWM-20A comes
with a metal drain line attached to the drain pan. If you do not have access to a drain, detach
the silicon elbow from the bottom of the drain pan, then inset the plug. Pan must then be emptied
periodically when full. If you do have access to a drain follow the instructions on the next slide
Connect the drain line to the drain connection on the back of the unit.
Run drain line to an appropriate drain, if there is not enough downward slope
for the drain line to drain properly please use a drain pump, not included.
Carefully open side access panel with screwdriver.
Insert the alkaline chamber into the unit, twist to lock into place.
Using 3/8 inch tube connect temporary water line to angle stop valve and to the DWM-20A. In between
these points install the pressure regulator and shutoff valve. If necessary also install
a back flow prevention valve, not included. The temporary line helps to reduce total
installation time, but it's not a requirement. Plug power cord in the outlet, turn on main
switch, do not turn on hot water. Open the shutoff valve and angle stop valve. One
minute after turning the unit on the sparkling and alkaline buttons will begin to flash. Touch
and hold both buttons simultaneously for 3 seconds until all four buttons begin to
flash, then chiller bucket will take 5 to 10 minutes to fill. Once full, flashing will stop.
Dispense alkaline water until it runs clear. Fill up the hot tank by using the hot touch
button. When water begins to dispense from the nozzle, the hot water tank is full. Turn on hot
water switch, wait 10 minutes and dispense hot water to ensure it's hot. Check to see if warm
air is blowing from the grid at the back. While it takes one hour plus for the water
to become chilled, after just 10 minutes one can immediately see if by touching the blue
button water comes out cold already. Close the shutoff valve and angle stop valve. Dispense
alkaline water for 5 seconds to release pressure from the temporary line. Remove
temporary line, install one leak detector tea in between the all-in-one filters and pressure
regulator. Position the leak detector near the all-in-one filters. The leak detector will shut
off water supply if a leak is detected. Do not insert the battery in the leak detector until
finished. Using tubing and dividers connect filters in parallel and cut temporary line to better fit
in between filters and unit, then insert end of temporary line into the two-way divider.
Open angle stop valve and shutoff valve to flush filters, when water runs clear close
shutoff valve and angle stop valve. Insert tube end into water inlet of unit. After inserting
the water line insert the 1/4 inch CO2 tubing into the back of the unit. Attach CO2 regulator to tank,
use quarter inch tubing to connect regulator to your MODwater. Turn cap knob of regulator to set
pressure to 60 to 65 psi. Reference the operations manual for component/letter identification.
Open angle stop valve and shutoff valve. Note, the unit will take about one hour
to freeze ice bank. After this period, sparkling and chilled will be ready for dispensing. Check
for water leaks in all connections, dry all surrounding areas. Make sure leak detector
is dry and insert batteries into the leak detector. Congratulations! You've successfully
installed your MODwater. Please check the troubleshooting guide in the operations manual
if you experience issues. For further information, visit Hoshizaki website at HoshizakiAmerica.com
