Grease Grabber™ Power Play Kitchen Exhaust Pollution Control System

2. WASH: System goes through cycles to clean and

dry dirty ionizing-collecting cells

3. RESET: Returns the system to the NORMAL mode

if a WASH cycle is accidentally initiated

4. SLEEP: Waiting period after a WASH mode

Washing
Power Play’s PLC control is preprogrammed to
manually initiate and cycle through the wash, rinse,
dry and system standby steps, as described below.
To initiate a wash manually, with the system in the
NORMAL mode, depress the WASH push-button.
The WASH mode consists of 6 steps. FIGURE 6
describes the indicating light and system component
status while operating in the WASH mode. After the
WASH/FAN DRY cycle is completed, the system is
programmed to shut down and manual start next
morning. As indicated in FIGURE 6, there is a 5 minute
delay period, after wash initiation, before the wash
process begins. If the WASH cycle is accidentally
initiated, the operator may reset the system during
the 5 minute delay period, and the system will return
to NORMAL operation. If the system is reset after
the 5 minute delay period, the WASH cycle will be
accelerated and the system will return to the NORMAL
mode after the WASH cycle is complete.
During operation in the WASH mode, depressing
the EMERGENCY STOP button will immediately
shut down the system. The red light adjacent to
the EMERGENCY STOP button will illuminate until
the button is released. The system will continue to
operate in the WASH mode after the EMERGENCY
STOP button is released.

Reset Mode
On rare occasions, it may be necessary to reset
the system. This may be required if a WASH cycle
is inadvertently initiated. As indicated previously in
FIGURE 6, there is a 5 minute delay period after the
WASH button is pushed, before the wash process
begins. If the WASH cycle is accidentally initiated, the
operator may reset the system during the 5 minute
delay period, and the system will return to NORMAL
operation. If the system is reset after the 5 minute
delay period, the WASH cycle will be accelerated and
the system will return to the NORMAL mode after the
WASH cycle is complete.

FIGURE 7 on page 10 illustrates the sequence of
events that occurs when the system is reset during
the different stages of system operation. When the
system is in the RESET mode, the white RESET light
will illuminate on the control panel. It is recommended
that the system be programmed so that system on/
off and wash cycles are automatically initiated. This
programming will be done by the factory engineer
during commissioning.
