Blast (Off-On) - Zamboni FastICE DK - 11000 Operating Manual

• Operation:
- Illuminates the right light Red when in the OFF position
- Illuminates the left light White when in the ON position

Blast (OFF-ON)

• This switch will produce the maximum water flow rate possible from the system.
• Operation:
- Illuminates Red when in the OFF position
- Illuminates White when in the ON position (activates both upper and lower booms
and sets pump hydraulic control valve to Imax value for maximum water flow)
The FastICE system produces the best results with water at a temperature of 100 to 140 degrees F (40 to
60 degrees C).
The system uses (arena facilities sourced) warm water carried in a dedicated ice-making water tank on the
machine. The ice-making water is supplied to the spray nozzles by means of a hydraulically driven,
proportionally controlled centrifugal water pump. Hydraulic power is supplied by a dedicated single gear
pump section added to the standard pump stack as part of the FastICE system.
Solenoid-actuated, diaphragm-type water valves (one each for the upper and lower conditioner booms and
one for the board spray nozzle) are used to facilitate turning the water spray nozzles off/on, and are
selected manually by the operator via the boom control switches on Switch Bank 2. No throttling is
provided by the solenoid water valves. The water valves only provide off-on control. Nozzle flow is
controlled by pump speed (RPM).
When the system is active, water flow to the booms and/or board spray nozzle is monitored by a water
flow sensor located in the delivery piping between the centrifugal pump and the spray booms as well as a
pressure transducer located in the delivery piping after the pump.
Ground speed is monitored from a speed sensor over the output shaft of the gearbox of the machine. The
(speed) sensor signal is used to synchronize (adjust) water flow (water pump RPM) with the machine travel
speed automatically, providing a consistent application of water across the entire ice surface, regardless of
speed.
If the upper (spray) boom is active, automatic control of the boom valve will turn off water flow to the
upper boom if ground speed drops below a preset value, which is adjustable within the SETUP screen,
which will be discussed in a later section. The boom which turns off when the speed drops below the
specified value can also be changed.
The target water flow rate for a given driving speed can be increased or decreased by up to 50% by
turning the adjustment knob on the display or by depressing the rocker switch for flow scaling.
