FREEZE GUARDING
To avoid permanent damage to the truckmount, it is imperative to follow the freeze guard
procedure whenever the possibility of freezing temperatures exists.
When disposing of antifreeze follow local laws and regulations. Do not discard
into storm sewers, septic systems, or onto the ground.
Antifreeze is harmful or fatal if swallowed. Do not store in open or unlabeled
containers. Keep out of reach of children and animals.
Freeze Guard Procedure
With the truckmount turned off and the incoming water line disconnected, open 1.
the water box drain valve on the front of the truckmount. Allow the system to fully
drain.
Add 2 gallons of 50/50 antifreeze and water mix to the water box.
2.
Attach a section of solution hose to the outgoing solution tting on the front of the 3.
machine. Attach the opposite end to the recirculation tting. (If more sections of
hose are to be freeze guarded attach those inline.)
Start the truckmount and allow it to run for 2 to 3 minutes. This will distribute antifreeze
4.
solution throughout the truckmount.
Remove the chemical feed line from the chemical jug. Turn the selector valve to
5.
“PRIME.” This will vacuum the chemical remaining in the lines to the recovery
tank.
If using the recirculation kit, skip ahead to Step 8.
Remove the quick connect tting from the garden hose. Attach the quick connect to
6.
the machine. Using a vacuum hose attached to the recovery tank, vacuum the water
out of the quick connect. This will freeze guard the feed line to the water box.
Remove the quick connect from the truckmount.
7.
8. Spray the antifreeze and water mix out of the truckmount and into a container to
reclaim the solution. Run the truckmount until it stops.
The truckmount is now freeze guarded. Remember to ush antifreeze from the
9.
system prior to carpet cleaning. See the following procedure.
