1. Installation
The ScaleGard Pro System should be located on the incoming cold water line and preferably away from heavy traffic
areas. It should be mounted on a wall or support structure.
Important:
This product is designed for cold water use only
(less than 100°F/38°C). Passing hot water through this product may seriously damage the head and/or cartridges.
2. Connections and Mounting
Note:
The SGP-124BV & SGP-124SV comes with 3/8” NPT inlet and outlet ports. The SGP-124B, SGP-124S and the dual
systems come with 1/4” NPT inlet and outlet ports.
The ScaleGard Pro System may be used with metallic or non-metallic piping systems. Any non-metallic fittings used in
your installation must be of adequate rating for your line pressure.
Note:
The SGP-124BV & SGP-124SV contains an
internal shut-off valve in the filter head, therefore, no external shut-off valve is required. All other SGP systems require
a shut-off valve on the inlet side of the system.
Shut off incoming water. Mount system and connect installation fittings. Connect the incoming cold water line to the
system’s inlet connection. Connect the outlet to the equipment being serviced.
Note:
It is recommended that a flush
valve be installed on the outlet line for use during cartridge change.
3. Cartridges
The ScaleGard Pro System is supplied with one or two cartridges. Use of replacement cartridges other than those specified
will compromise water quality, cartridge life and product warranty.
4. Recommended Replacement Changeout Indicators
Cartridges should be changed on or before the predicted end of life. To calculate minimum changeout period, use the
following:
Divide capacity (in grains) by water hardness (in gpg)
or:
Divide capacity (ppm-liter) by water hardness (in ppm)
5. System Start-up
SGP-124BV & SGP-124SV with internal shut-off:
Push new cartridge into head with slot on cartridge in line with the word “OFF” on head. Top surface of the cartridge
will become flush with the bottom of the head when fully engaged. Turn cartridge approximately 90° to the right until it
hits a stop.
SGP Systems without internal shut-off:
Position new cartridge into head by lining up cartridge ‘ears’ with the opening on the head. Push cartridge into head
until firmly seated. Turn cartridge to the right approximately 1/4 turn until it stops. Repeat for the second cartridge.
Note:
If a flush valve has been installed, run tubing to a bucket or appropriate drain. Turn on incoming water supply and
open flush valve. Flush for 2 minutes to thoroughly wet media and bleed any air from the cartridge. Turn off flush valve.
Remove tubing from drain. The system is now ready for service.
