Finish Thompson CQC-HD - Manual (Page 16)

Helpful Hints
• It is recommended that during initial operation the drain and fill pumps be primed. To do this, pour
approximately one gallon of water into the upper fill container.
FILL PUMP - place the valve in “container fill” position and turn on fill pump until flow is observed
through the bypass loop. Turn off the fill pump.
EVACUATION PUMP - place wand in fill container and turn on evacuation pump. Water flows into
waste coolant drum. Turn off evacuation pump when fill container is empty.
• The CQC-HD was shipped with four spare impellers. Keep these in a known location for future use.
• Do not let the pump run dry for more than 20 seconds. Damage to the flexible impeller can occur if
run dry for a longer period.
• Do not suck up undiluted “sludge” from the radiator overflow bottle. Use a hose to loosen and dilute
the “sludge” with water first.
• Do not allow the operator to leave the machine unattended during the process.
• Vehicles with pressurized overflow bottles hook up the same way as non-pressurized designs.
• If steam is noticed coming out of the 30-gallon drum during the process and no new coolant is
flowing in, turn the vehicle off and leave both the fill and drain valves open and the fill pump
on. Wait a few minutes until the level in the fill container starts to drop, then start the vehicle and
complete the process normally.
• If you notice fluid draining from the radiator reservoir bypass, it means that your thermostat has not
opened sufficiently. Shut off the fill pump, fill and drain valves, and rev the engine for 3 to 4
minutes to open the thermostat. Start the fill pump, open the fill and drain valves and complete the
process as you would normally.
• Fill container can be filled in any one of several methods. Use the coolant fill hose to pump from a
55-gallon drum, buckets, or single gallon containers. A mixture of antifreeze coolant and water can
be made up into a clean 55-gallon drum or concentrated antifreeze can be pumped into the fill
container followed by the appropriate amount of clean water. Be sure to add the appropriate amount
of SCA’s (Supplemental Coolant Additives) if required. Fill container has a large 3” threaded opening
at the top that can be utilized to manually pour fluid into the container.
• In cold winter months, mixing warm water with antifreeze can help the coolant change faster by
helping to keep the thermostat open.
• Keep an eye on the temperature gauge to make sure the vehicle is not overheating
