Finish Thompson CQC-HD User Manual

DESCRIPTION:

Introduction

The CQC-HD (
handling equipment. This portable unit safely drains and refills larger engine-cooling systems in a
fraction of the time it takes for conventional methods. When properly operated, this unit induces no air
and less than 5 psi pressure into the engine’s cooling system. No hose cutting or tee is required – the
CQC-HD fill pump and the engine’s own water pump perform the service.

YOUR RESPONSIBILITY:

The

user

of a CQC-HD is solely responsible for all environmental and safety concerns or laws

pertaining to the use and disposal of antifreeze/coolant handled or produced by this equipment.

Do your part for the environment. Recover, recycle when possible, and dispose of wastes in a proper
manner. Finish Thompson also manufactures high quality vacuum distillation equipment for use in
recycling antifreeze. For more information on this product, call Finish Thompson at 800-934-9384.

Safety Precautions

!

CAUTION:
FAILURE TO FOLLOW THE PROCEDURES AND PRECAUTIONS AS OUTLINED IN THE
OPERATION MANUAL CAN RESULT IN DAMAGE TO THE ENGINE, VEHICLE OR
EQUIPMENT AND IS NOT SUPPORTED OR WARRANTED IN ANY WAY.

WARNING:

!

FAILURE TO FOLLOW THESE PRECAUTIONS CAN RESULT IN SERIOUS INJURY
OR DEATH.

• Read and understand the operation manual completely before operating this unit.

• Always wear proper eye and skin protection when operating and maintaining this equipment.

• Hazardous voltages present. Use only with a grounded electrical outlet (GFI Circuit recommended)
and grounded extension cords. Do not remove the ground prong from the plug.

• Take precautions to keep clothing, hair, hands, hoses, etc. away from all moving parts on the vehicle.

• Cooling systems can be under pressure and extremely hot. Allow the cooling system to
cool down and use extreme caution when removing caps and hoses.

• Antifreeze/coolants are poisonous to people and animals and are also corrosive. Clean up any spills
immediately.

• Continuous monitoring of the quick-change process is required. Leaving the vehicle unattended
while operating this equipment can result in damage to the engine, vehicle, and/or equipment.

• Check for proper operation of quick-change pump and bypass loop. Failure of pump or bypass loop
to operate properly could lead to engine damage.

• Unit is supplied with two locking casters. Make sure they are in the locked position when operating
the equipment.

Assembly

INSTALLATION OF SWIVEL CASTERS:

Locate the 4 swivel casters and bag of hardware that was shipped with the unit.

Have a helper tilt the unit on its bottom edge to install each caster. Insert the bolt from the top, with
the washer and nut on the bottom. Tighten with a 1/2” wrench or socket.

Sequence of Operation

This section is a brief overview of the operation of this equipment. The CQC-HD is a machine designed
to perform quick and simple engine coolant changes on larger trucks, tractor-trailers and construction
equipment, forklifts, pickup trucks and automobiles. When properly operated, this quick change can
be accomplished in as little as ten minutes. The following is the normal sequence of operation for a
CQC-HD. Refer to the “Performing a Quick Change” section of this manual for complete instructions
before operating your unit.

PREPARE FOR THE QUICK CHANGE - A vehicle (with engine still warm to hot) is pulled
into the service area and the CQC-HD is positioned. An appropriate amount of new or recycled coolant
is mixed and then pumped into the CQC-HD fill container. Check the vehicle’s operator manual for
cooling system capacity information. Fill the container with the correct amount of coolant.

USE THE DRAIN PUMP - Waste coolant is removed from the vehicle’s overflow container using
the CQC-HD red suction hose and drain pump.

CONNECTING THE

The green fill hose attaches to the neck of the radiator and the black drain hose is attached to the
vehicle’s cooling system through the open end of the upper radiator hose. No hose cutting or tees are
required.

PERFORMING THE QUICK CHANGE – Open the fill valve on the green hose. Leave the
drain valve on the black drain hose closed. Turn the fill pump on. The level in the fill container will
drop, then stop dropping. Close the fill valve and stop the fill pump. Open the vehicle thermostat by
starting the engine and raising the RPMs to running speed for 3-5 minutes. Open the drain and fill
valves and start the fill pump. When the amount of clean coolant drops to the predetermined setting of
the coolant system capacity level, the process is complete.

Note: A special bypass loop is connected to the discharge of the fill pump and prevents the over pressurization of
the engine cooling system. A pre-set pressure relief valve in the bypass loop allows coolant to re-circulate back to
the fill container if the thermostat is closed or partially open. The maximum pressure applied to the engine’s cooling
system is 5 psi.

DISCONNECT THE CQC HD – The CQC-HD is disconnected from the vehicle and the vehicle’s
radiator hose is reattached.

TOP OFF - The radiator and overflow bottle are filled to proper levels using the green fill hose and

fill pump. The engine is started to check for leaks.
