Optional drain pump installation – MARVEL Scientific 6ADi User Manual
Page 6

The Marvel Drain Pump is designed to remove drain water from
ice machines installed in areas without direct drainage access.
The sealed reservoir pump collects the melted ice water and
pumps it to a maximum lift of eight (8) feet through 3/8” I.D.
vinyl tubing to a drain.
This pump has been evaluated for use with water
only.
NOTE: Despite the ease of installation, reasonable care and safe
methods should be practiced. Do NOT work with energized elec-
trical equipment in a wet area. Read and follow the installation
instructions listed in this manual.
Risk of electric shock - This pump is supplied with a grounding
conductor and grounding-type attachment plug. To reduce the
risk of electric shock, be certain that it is connected only to prop-
erly grounded, grounding-type receptacle.

Maintenance
The following items require review on a regular basis.
1. Check that the inlet tubing from the ice machine drain to the
drain pump is open and is free of foreign material. Inspect
the screen at the top of the inlet tube to ensure there is
nothing blocking water flow to the pump.
2. Check that the vent line is open, free of kinks/sharp bends,
so that air flows freely from the pump reservoir.
3. Check that the discharge tubing is free of foreign material
(algae, etc.) and kinks/bends. Confirm that the check valve
is operational by observing that the water flow is evident in
one (1) direction only - out of the pump. Remove and clean
as required.
Troubleshooting
NOTICE: If the drain pump reservoir (not the ice machine bin)
reaches overfill condition, the power to the ice machine will be
shut off.
If the ice machine is not working, check the following:
• Make sure there is power at the receptacle.
• Make sure the ice machine is turned on.
• Make sure the ice bin is not full.
Then check the drain pump:
The pump does not run:
• Make sure the pump is plugged in and there is power to the
receptacle.
• Check the inlet screen for debris and clean as needed.
• Make certain the vent line is free of kinks/sharp bends or
restrictions.
• Make certain there is enough water to activate the drain
pump. It will take at least one (1) quart of water to activate
the drain pump.
The pump runs, but no water is pumped out:
• Check that the vent is clear and free of restrictions.
• Check the discharge line to make certain there are no re-
strictions.
• Make sure that the discharge tubing has not exceeded the
maximum lift of eight (8) feet and the horizontal run is not
greater than twenty (20) feet.
The pump runs and then quickly turns off repeatedly:
• Check to make certain the drain pump is level.
• Check that the vent is clear and free of restrictions.
