OPERATION

3-5. Manual Mode

This mode of operation is the NFPA required manual override. This mode is used to activate the foam pump without

the flowmeter operating.

Figure 3-9: Control Head in Manual Mode

1311, 1357

NOTE: Manual mode is based on 100 GPM flow rate of water, i.e.; .5% = 1/2 GPM concentrate. If you know

your hand line flows 200 GPM and you want .5% injection; you would:

• divide 200 by 100 which equals 2.

• 2 times .5% equals 1%.

• 1% is your setting.

1. Turn system ON (green LED will illuminate).

2. Press and hold the INC % and the DEC % buttons until the first LED decimal point (to the left) is flashing for 3

seconds.

NOTE: Adjusting percentage to zero will stop the foam pump from flowing, but will leave system in manual

mode.

3. Monitor and adjust for estimated water flow rate changes.

4. Turn foam pump OFF to stop manual mode OR turn the battery switch OFF.

3-6. Set-up Mode

Refer to Para 4-2.1, Set-up Mode for Set-up Mode information.

In this mode, the foam pump will run regardless of water flow. If discharges are closed, these lines may

be charged to over 300 PSI. At least one discharge or manifold drain must be open before entering this

mode.
