1. Add a 50% water, 50% glycol anti-freeze mix to the

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
diaphragm 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
temperature.

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.
