INSTALLATION REQUIREMENTS
The model SPS600V and SPS620V water filters are designed to be
installed in the cold water line only. Installation of the water filter in
a hot water line can seriously damage the filter housing. The filter
must be in contact with water at all times after installation. Installation
must comply with any existing state or local plumbing codes.
Refer to the Water Parameters table, right, for recommended water quality limitations. If your
local water supply does not meet the recommendations in the Water Parameters table, Vulcan
may request that a water sample be returned for laboratory testing. After evaluation of the water
test, other specific recommendations may be made for additional filtration or water treatment to
make the local water supply meet the acceptable limits for use in steam generator equipment.
The recommended incoming flow rate for SPS600V is 2 gallons per minute
(7.6 liters per minute).
The recommended incoming flow rate for SPS620V is 4 gallons per minute (
15.1 liters per minute).
The SPS600V and SPS620V water filters must be protected against freezing. Failure to do so
could result in breakage of the filter housing and water leakage.
Minimum operating temperature: 45°F (
7°C). Maximum operating temperature: 100°F (38°C).
Minimum operating pressure: 20 psig (
138 kPa). Maximum operating pressure: 125 psig (862 kPa).
Minimum line pressure: 40 psig (
276 kPa). Maximum line pressure: 125 psig (862 kPa).
If the filter pressure gauge is over 60 psig (
414 kPa), you must reduce the pressure to the boiler
to a maximum of 60 psig (
414 kPa). Install a water pressure reducing regulator (part number
854322 or equivalent) after the filter, move the pressure gauge downstream of the regulator and
set the pressure at 60 psig (
414 kPa).
Do not use with water that is microbiologically unsafe or of unknown quality without adequate
disinfection before or after the filter.
PLUMBING CONNECTIONS
WARNING: PLUMBING CONNECTIONS MUST COMPLY WITH APPLICABLE SANITARY,
SAFETY AND PLUMBING CODES.
The filter housing on models SPS600V and SPS620V
comes with
3
/4" NPT internal pipe threads on the inlet
side. The inlet is on the left; outlet is on the right, after
the pressure gauge and the water meter. The outlet
side of the water meter comes with a
3
/8" NPT internal
pipe thread connection.
Connect the incoming cold water line to the water
filter's inlet connection (left side).
Connect the incoming water line to the boiler (or steam
generator, steamer or combi oven) from the outlet side
of the water filter (right side of water meter).
Steamers and combi ovens with two water connections
have a boiler or steam generator feed line and a cold
water drain line condenser feed line. Connect the drain
line condenser feed line to the tee using the
3
/8"
compression fitting for
3
/8" copper tubing, provided
(Fig.1).
