Hose Bundle Heating System
1. Add a 50% water, 50% glycol anti-freeze mix to the
small translucent tank located at the bottom right
corner of the front of the sprayer module.
NOTE: Even in warm climates, a water/glycol mix
should be used to keep the circulation system clean and
working properly.
2. With air supply on, adjust the silver knob on top of
the diaphragm pump to start the small black dia-
phragm pump under the tank. Adjust pump to
approximately 2-3 cycles per second.
3. Continue to add the 50/50 fluid mixture as air is
purged from the fluid lines but make sure the tank is
no more than 1/4 to 1/3 full when cold.
NOTE: Re-tighten all heated fluid circulation tube fittings
after the first time the system has been run at full tem-
perature.
Double-Walled Tank Heating System
NOTE: The double-walled tanks are pre-filled with a
water/glycol mix at the factory. If your tanks are already
filled, skip this section.
NOTE: On all models, there is only one pump and one
heater, which is located on the "A" side feed module.
1. Add a 50% water, 50% glycol anti-freeze mix to the
small translucent tank located between the tank and
feed pump on the feed module.
2. Turn the agitator and tank heated fluid pump air ball
