MAINTENANCE
The ArrowMAX 2.0 is designed to give years of trouble-free use. Acuva products use state-of-the-art
UV-LEDs, meaning there are no mercury bulbs to replace. However, there are some simple tasks that
should be performed to ensure continued operation.
Regular Maintenance
1. Check monthly that none of the connectors are leaking.
2. Replace the in-line filter after winterization or as per the instructions on the filter label.
Note: The small quartz windows inside the unit does not reach high temperatures to encourage
mineral build-up (scaling) as with UV lamp systems. As a result, no significant scaling or loss of
performance due to scaling over time is expected.
Winterizing
WARNING
If the device is installed in a Recreational Vehicle (RV) ensure that the RV is winterized as per
its owner's manual.
Failure to properly winterize the Acuva
temperatures can lead to damage and water leakage.

Verify that the unit is connected to power
and that the input voltage is within
specifications (11-16V).
Ensure the inlet and outlet tubes are
connected to the respective fittings
marked "IN" and "OUT" on the device.
The flow sensor inside the unit requires
a minimal water flow to activate the
system (approx. 0.3 L/min). Ensure there is
enough water pressure (i.e. 12 PSI) in the
line to reach this flow.
Unplug and plug in the device's power
jack. If this fault persists, contact Acuva
for support.
Verify that the input voltage is above 11
volts.
