3-1: Freeze Guard
3 - Freeze Guarding
When operating the CTS 403 Flex during the colder months of the year, ensure that you
properly freeze guard the System. No part of the CTS 403 Flex is covered by warranty if
machine damage occurs because of freezing.
BE SURE YOUR MACHINE IS PROTECTED! Freezing will cause component
damage.
The following precautions are recommended prior to and during cleaning jobs:
1. Run the machine before leaving for the rst job to ensure nothing has frozen the
night before, including hoses and tool/wand.
2. Insulate the solution hose from the cold ground by running it through an extra 1½”
vacuum hose.
In colder climates, insulating the vehicle walls and oor boards will help protect
the unit.
Do not procrastinate during the cleaning operation or the hot water solution line
will also freeze on the ground. The solution line should be insulated in extremely
cold climates.
Whenever possible, store the van in a heated garage at night or over the weekend.
If not possible, place a 1,500 Watt electric heater inside the vehicle, aimed directly
at the machine.
Never use a propane heater. It causes excessive moisture on the vehicle ceiling
and the possibility of it malfunctioning is therefore higher, which may cause bodily
injury. If the CTS 403 Flex and vehicle are left outside with a heater, drain water
from the cleaning tools and hoses because they can be freeze damaged also.
