Tank Connection
1.
Locate the optionally supplied tank
as close as possible to the RO
system.
2.
Place the tank on a smooth, flat
surface that can support at least 73
kg (160lbs).
3.
The tank connection is 1” NPT. It is
recommended that a shut-off valve
be installed on the line to the tank
connection.
4.
Because of the high quality of the
RO water, plastic tubing or piping
should be used to connect the tank.
5.
Before connecting the tank, the air
pre-charge should be checked.
Check Tank Air Pre-Charge
Tools and supplies required:
Air Pressure Gauge, 5-40 psi range (0.3
- 2.7 bar) with tire valve (Schrader Valve)
connection.
Source of compressed air (manual bicycle
tire pump or air compressor).
1.
Unscrew the protective cap from the
air valve on the tank.
2.
Use the pressure gauge to check the
tank pre-charge for pressure. The air
charge should be 5-8 psi.
y
To add pressure to the tank, use
a manual bicycle tire pump or
other source of compressed air.
y
To release pressure from
the tank, press the center
pin on the air inlet valve.
3.
Once the tank air charge is set,
replace the protective cap on the air
valve.
Drain Connection
The drain is for flushing particle buildup out
of the system during operation.
Install a sufficient length of 3/8” OD tubing
(not supplied) from the drain outlet on top
of the RO system to the drain.
When connecting the drain hose, pay at-
tention to the following guidelines:
y
The drain line plumbing must be
able support the flow rate when the
system operates.
y
The drain line leading out of the
system must be as short as possible
and slope downwards without any
kinks or loops.
y
The drain line plumbing must be
positioned and secured at least 2
inches above the drain (Figure 4).
This air gap protects the system
from contamination in the event of a
backed-up drain.

Drain Line Plumbing
y
The drain used must not be blocked
or restricted.
y
The drain used must be as large or
larger than the drain line plumbing.
y
The drain line from the system
should be secured at the drain using
appropriate mounting hardware.
NOTE:
The drain MUST accommodate a
flow of up to 3 gpm.
