Aqua-Pure MCA2001M - Manual (Page 10)

Typical examples of proper drain line diameters are:
1 )1/2 in. ID up to 15 ft. when discharge is lower than inlet.
2) 5/8 in. ID up to 15 ft. when discharge is slightly higher than inlet.
3) 3/4 in. ID when drain is 25 ft. away and/or drain is installed overhead.
Some areas prohibit the use of fl exible drain lines. Check with local code offi cials prior
to installation.
Step 10
Position the drain line over the waste drain pipe and secure fi rmly. To prevent back si-
phoning of sewer water or grey water, provide an air gap of at least two inches or 2 times
the pipe diameters between the end of drain line tubing and waste drain (Figure 5). Do
not raise the drain line more than 10 feet above the fl oor. Check with local code offi cials
to ensure you conform to local, state and national plumbing codes.
Step 11
Open the valve on the water supply as required to pressurize the water lines to the dwell-
ing or fuel source. The power to the water heater or boiler needs to be established once water has been allowed to fl ow back into the device, if it was
drained at any time during the installation. Plug the control valve into a properly grounded 110/120V 60 Hz non switched electrical outlet. Check with
your local code enforcement offi ce to determine if it meets local codes.
Step 12
Turn back on the power source to well pump and slowly open the shut off valve to pressurize the water system. If on a public or community water supply
open the main shut off valve to the dwelling.
Step 13
Set the time of day by referring to Page 4-3 “How To Set The Time-Of-Day”.
Step 14
Check for leaks on all connections, correct as required.
Step 15
Manually initiate backwash of the Iron Reduction System by referring to the “How To Manually Backwash Your Filter At Any Time” on page 4-3.
Step 16
Once the valve is in the backwash position slowly open the inlet side of the bypass valve to allow water to fl ow into the fi lter vessel. Water should start
to fl ow into the drain. Allow for any air that might have been trapped to leave the fi lter and go to drain. This will be detected by changes in noise in the
drain line or is visible in the semi-transparent tubing. Once the air is entirely gone slowly increase the water fl ow to drain by opening the inlet side of the
bypass valve until fully open. Refer to Figure 4 for correct positioning. At the end of fi lling, the water should be clear. If not, allow the valve to complete
the manual backwash process and initiate once again. It is very important to allow the unit to purge all fi nes from the media in the fi lter vessel to the
waste drain prior to using the water. Once the fl ushing process has been completed you now can open the outlet side of the bypass valve to allow for
fi ltered water to fl ow into the dwelling.
IMPORTANT NOTES IMPORTANT NOTES
Due to the nature of the MCA Series Iron Reduction media, on start up it sometimes requires 2 or 3 days for the Aqua-Pure ® MCA Series Iron Reduction
System to reduce Iron and Manganese below staining levels. Do not be alarmed if this occurs. During the initial start up and subsequent fi rst couple
automatic backwash cycles, a small amount of fi ne white and beige media may be observed in the drain water and or drain area. This is normal and
benefi cial for the effi cient operation of your Aqua-Pure MCA Series Iron Reduction System.
Step 17
The frequency of backwash is factory preset at every 4 days. If the iron content is greater than 5 ppm, is red water or bacterial iron, the unit should be
washed more frequently. See tables to determine the frequency. Also if the water has tannin-lignin or hydrogen sulfi de present, the fi lter should back-
wash every day. Refer to Section 4 for backwashing instructions and frequency.
