Technical Description and Application Notes for TSC Proofer Oven Backow Preventer Assembly
This equipment is intended to be connected to a
potable water supply system under pressure and is
to be installed with adequate backflow protection
to comply with all applicable federal, state, and
local codes.
Water supply pressure for proper operation shall be:
Minimum 40 PSIG(275 KPa)
Maximum 65 PSIG(448 KPa)
measured at water line inlet to the equipment.
If so equipped, regular maintenance is required to
replace the water filter cartridge at least once per
year, and to clean the inlet water screen at least
once per year. Consult state/local codes for any
additional requirements.
INSTALLATION OF WATER FILTER
Install new filter by removing sanitary cap from top
of cartridge, insure two black O-rings are in place,
then lift up into filter head and rotate cartridge
1/4 turn counter clockwise until it comes to a complete
stop. Flush 2 gallons (7.5 Liters) of water through the
new filter before using proofer to purge air from filter.
Remove hose from bottom of proofer by loosening
the compression nut at the disconnect fitting
and pull hose out. Place hose over container and
turn on water. It will take a minute for the filter
to fill before water flows out of hose into container.
Once filter is flushed with 2 gallons (7.5 Liters) of water,
turn off water supply again, insert hose into water line
disconnect, tighten compression nut and turn
water supply on again. Check for leaks at
connection fittings.
Patent(s) Pending
512776 D
Check with your local authority having jurisdiction
regarding approvals for connecting the Duke
TSC Proofer Oven to a potable water supply
before making any plumbing connections.
Plumbing code requirements vary, but Duke has
a kit (P/N 600187) available or installed as a
factory option, for backow prevention to protect
water supply systems by preventing the reverse
ow of non-potable water into the potable
domestic water system. The device consists of
two independently acting check valves, internally
force-loaded to a normally closed position
and designed/constructed to operate under
intermittent or continuous pressure conditions.
The two main components of the Duke backow
preventer system are:
• Dual Check Valve type backow preventer
that conforms to ANSI/ASSE standard
#1024 and is CSA standard B64.6 certied.
• Inlet water strainer equipped with 100-
mesh screen and installed up stream of
the backow preventer. The screen is
conveniently located on the rear panel of the
proofer, below the backow preventer, for
easy access during cleaning/replacement.
