*
The Rainfresh UV Water Disinfection System is designed for installation on the cold water line only, either at the point of entry
(POE) or at the point of use (POU). For installation in the Province of Quebec, install the R519 to serve a max of 1-2 outlets
and the R830 to serve a max of 2-3 outlets only, but not serving majority of the premises.
*
The system should be installed indoors in a protected area where the temperature does not fall below 4°C (40°F).
* It is strongly recommended to have a
dedicated electrical circuit
for the UV system. Where power fluctuations or surges are
anticipated, it is recommended that a surge
protector be installed. We recommend a CSA or
equivalent certified
surge protector
rated for a
clamping voltage of less than 400 Volts, response
time of less than one nanosecond, and energy
absorption of at least 600 Joules.
*
The R830 & R519 UV systems have been
designed for maximum water flow rates of 8 US
GPM (30 liters per minute) and 5 US GPM (19
liters per minute) respectively. If higher flow
rates exist, it is recommended that an 8 US GPM
flow restrictor (Rainfresh model FR8K) be installed
at the inlet port of model R830, so that the flow
rate through the UV does not exceed the
rated flow rate. Likewise, for UV model R519, a 5
US GPM flow restrictor (Rainfresh model FR5K) is
recommended.
*
For optimum performance, the system should be
wall-mounted in a vertical position with the lamp
connector at the top. The water inlet is at the
bottom and the outlet at the top, as shown in
Fig. 1.
* It is highly recommended to install
bypass piping
with a shut-off valve around the unit. This way you
can still have water in case you need to remove
the UV unit for service.
*
Provide a minimum clearance of 2 feet above the
unit for lamp replacement.
*
Use only Teflon tape for all connections. Do not
use any other sealant.
* The UV Disinfection unit should be the last step of your water treatment system. If your water comes from a well or a lake/river
etc, the UV should be installed after your pump, pressure tank, softener/iron filter/water conditioner. Otherwise the UV should
be installed just after the water meter and any water conditioner that you may have.
INSTALLATION
Fittings Required for Installation
Fittings required for a typical install on 3/4” copper pipe are 3/4” FNPT female adapters, 3/4” Tee, 3/4” Elbows, 3/4” copper pipe,
3/4” union couplings and 3/4” ball valves. You may need different fittings if your pipe size or material is different. If you are unsure
of what fittings to use, please call Envirogard/Rainfresh.
Note:
UV light can degrade plastics. If your plumbing pipes are in plastic, it is recommended that you use at least 6 to 12 inches
of UV-resistant material (e.g copper) on the inlet and outlet of the UV unit to prevent damage.
Installing the pre-filter
It is highly recommended that a 5 micron or finer filter be installed before the UV system. Pre-filter is NOT included with this
system, but is available from the same retailer. We recommend Rainfresh model FC100 or FC150 with solderless installation kit
model CK1. Refer to fig(2) for location of filter and follow installation instructions included with filter.
Installing the UV unit.
1. Slide a mounting clamp (4033) under a mounting base (4034) and screw the base on to the wall with base screws (4035) as
shown in Fig. 1. Using a level, vertically align other mounting base at a distance of about 11-12 inches below the first base.
Mount the other base with the second mounting clamp (clamp screws should be in opposite directions).
2. Mount the UV disinfection chamber (4000/4010) on the two bases and holding it with one hand, tighten the mounting clamps
using a flat-head screwdriver.
3. Mount the ballast (R830B/R519B) on the wall slightly above the chamber with ballast mounting screws (4044) (See Fig. 2).
4.
Install new plumbing as per Fig 2. The inlet and outlet connections on the UV are 3/4” MNPT.
5. If you intend to drain the UV during winter to prevent freezing, install a 3/4” copper tee at the inlet of the UV and plumb in a
ball valve and a piece of copper pipe (See Fig 2)
