3. Water Pump - The heart of the standard TYMCO water system is an electric pump.
This pump puts out 5.0 GPM at 25 PSI. No service is required; however, the pump
must be protected from freezing (See Winterization).
4. Spray Nozzles - The operator is responsible for keeping the spray nozzle tips clean
and spraying.
ATTENTION: On the Model 600 it is important to use only the correct output
spray tips in order to realize proper water system spray time
and pressure.
a. If a spray nozzle is stopped up, the entire tip assembly must be removed for
cleaning. To clean tip, use the edge of a knife or razor to clear tip spray slot.
Then grasp the tip between the index finger and thumb with slotted side facing
up. Strike tip sharply against a clean, hard surface to dislodge blockage.
DO NOT USE DRILL TO MAKE ORIFICE LARGER!
b. To re-install tip, insert tip into cap and hand tighten cap to nozzle assembly.
Then use pliers, in one hand, to hold tip in desired position, then with other hand,
use wrench to tighten cap which locks tip position.

C. WINTERIZATION
To winterize the Model 600 water system, the system should be filled with solution of
propylene glycol. Follow procedures outlined below:
1. Disconnect siphon hose from water tank.
2. Submerge hose end into container of propylene glycol.
3. Start auxiliary engine and run at idle. Turn water switch on until propylene glycol
is observed to spray from nozzles. Then turn water switch off.
4. Make sure water tank is DRAINED!
5. System is now winterized.
