R250| LGR Dehumidifier Installation, Operation, and Maintenance Instructions
IMPORTANT
IMPORTANT: DO NOT operate the unit without the filter or with a less effective filter
as the heat exchanger and coils inside the unit could become clogged and require
disassembly to clean.
4.2 STORAGE AND FREEZE PROTECTION
There are two issues to consider when the Phoenix R250 is stored between uses
and both pertain to water trapped in the unit. The first is biological growth and
the second is damage caused by freezing. The effects of the trapped water can
be greatly reduced if precautions are taken to remove as much as possible before
storage.
1. Use the pump PURGE button to reduce the water level in the reservoir.
2. Stretch the hose flat to drain it completely. Raise one end above your head
and spool hose while draining water out the other end.
3. To reduce biological growth flush the unit with a bio-fungicide that is approved
for use with copper,aluminum and polyethylene. To flush:
a. Run the hose to a drain.
b. Plug in the unit but do not turn it on.
c. Remove the air filter. Slowly pour a quart of the antimicrobial through the
heat exchanger.
d. Hold in the pump purge switch to reduce the water level in the reservoir.
e. Flush with water.
4. If the unit will be exposed to freezing temperatures, after purging, pull back
the filter and pour 1 cup (8oz) of a alcohol based windshield washer fluid
through the heat exchanger. It will flow down into the pump reservoir. Do NOT
purge the solution out of the unit.
5. Dirty filters should be changed prior to long term storage to prevent biological
growth on the filter.
