Stop the drying cycle, with the flame sensor wire still
removed, restart the drying cycle.
The HSI will turn on, and after a few seconds later the gas
valve will be energized and the HSI will shut off. Ignition
(flame) should be evident for approximately 7-seconds and
then shut off.
The HSI module will attempt to light burner only “once.” If
flame is not reestablished the HSI module will lockout and
the “red” indicator light will flash continuously.
Functional check of the HSI module is complete.
Replace the flame sensor wire from the S2 terminal to the
HSI module.
Phase 7 Non-Coin System Diagnostics
IMPORTANT: You must disconnect and lockout the
electric supply and the gas supply or the steam supply
before any covers or guards are removed from the
machine to allow access for cleaning, adjusting,
installation, or testing of any equipment per OSHA
standards.
All major circuits, including door, microprocessor
temperature sensor, heat and motor circuits are monitored.
The Phase 7 non-coin microprocessor controller (computer)
will inform the user, via the L.E.D. display of certain failure
messages, along with L.E.D. indicators on the input/output
board on the back panel of the front right control door.

Water Information ____________________
Before You Start!
Check Local Codes And Permits
Call your local water company or the proper municipal
authority for information regarding local codes.
IMPORTANT: It is your responsibility to have all plumbing
connections made by a qualified professional to assure
that the plumbing installation is adequate and conforms to

Installation
Requirements
The connection point to the electric water solenoid valve is
a 1/2” M.P.T., the S.A.F.E. system must be supplied with a
minimum water pipe size of 1/2-inch and be provided with
40 psi +/- 20 psi (2.75 bar +/- 1.37 bar) of pressure. For use
of optional manual bypass, a second source with the same
piping and pressure requirements is required.
Flexible 1/2 feeds must be provided to avoid damage to
electric water solenoid valve by vibration.
