4-3: Freeze Guard
DRAINING THE CDS
To drain the machine, follow these steps:
1. Before shutting o the machine, remove the chemical line from the chemical jug and
place in a mixture of 50/50 antifreeze and water. Turn the CHEMICAL SYSTEM valve
to the ‘PRIME’ position until coolant registers in the ow meter. With the cleaning
tool on, allow mixture to ll the remainder of the chemical system.
2. Open the water box drain valve and allow the water to drain thoroughly from the
water box.
3. Close the water box drain and ll the water box with 50 / 50 antifreeze and water
mixture. Run the unit for 1 minute to circulate the mixture through the machines
low-pressure hoses. Spray through the wand or other tool into a suitable container
until the water box shut-o switch activates (pump stops). This freeze guards the
high-pressure circuit
4. Open the water box drain and drain out the residual uid into a suitable container.
This antifreeze solution may be retained for reuse (attach freeze guard tting to inlet
quick connect and vacuum water out of the inlet line).
WHEN DISPOSING OF USED ANTIFREEZE COOLANT: Follow local laws
and regulations. If required, dispose at facilities licensed to accept household
hazardous waste. If permitted, dispose in sanitary sewer systems. Do not discard
into storm sewers, septic systems, or onto the ground.
