INSTALL DRAIN LINE - THIS IS A SIMPLE BUT IMPORTANT STEP TO AVOID CROSS-CONTAMINATION
8. Plumb rigid tubing only (PVC recommended if code applicable) directly to the 1” MNPT drain fitting.
NOTE: Install a union on the drain line in order make any service or need to disconnect easier in the future.
9. Connect and route the drain line to the drain point. Install a non-restrictive spring check valve within 2 feet of
the control valve to prevent possible back flow and cross-contamination
CAUTION:
• Never install drain line or connect to any drain line less than 3/4”
• Any drain line exceeding 20 feet in total length and/or is expected to flow over 5 feet above the height of
the drain port requires an installed drain line of no less than 1”.
10. Locate the end of the drain line at a suitable drain point and create an air gap.
NOTE: Outside system draining is allowable. It is only filtered water and not a brine discharge.
CAUTION:
• Do not freeze. Do not block or bury water flow. Drain line and surroundings must be pitched or sloped to allow
for proper water flow and drainage where drain water never sits in the line or any landscape or rain water
is allowed to create standing water at the drain line. Allow enough space (lawn, planter, water storage) to
flow and absorb up to 140 gallons (eqivalent to 4 showers) of water every 6 days.
• If using a sink, floor drain or any other drain point, an air gap is required and the drain point needs to be
capable of draining water away at up to 7 (gpm) gallons per minute for up to 20 minutes (similar to 4
showers once every 6 days) to avoid water damage.
CAUTION:
• Secure (clamp, tie or wire) installed drain line in place at the drain point to prevent movement and avoid
any possible water damage.
Installation Instructions - All Systems - Drain Line and Electrical
INSTALL ELECTRICAL CONNECTION
11. Connect electrical power by plugging the transformer into a 120V grounded
and unswitched electrical outlet.
If outlet is over 7 feet away use 18 gauge extension to connect up to
100 feet away. Do not exceed 100 feet.
NOTE:
Power consumption is that of a radio alarm clock, doorbell or timer clock
used for sprinklers or irrigation.
PROCEED TO THE PROPER TANK FILL OF THIS SYSTEM
REQUIRED:
• Provide a minimum 1/2” air gap between the end of the drain line
and the drain point. (see illustration to the right)
• Install a non-restrictive spring check valve in drain line within 2 feet
of the control valve
CAUTION:
• Air gap and proper air flow and ventilation (Caution: attics and crawl
spaces) is necessary to prevent any back up or cross contamination
into system. Do not enclose or cover up drain point. It would be best
if you can see the water flowing from the drain line into the drain
point. (see illustration to the right)
