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.
When draining solution from the machine, wear protective eye wear and ensure
the solution temperature is cold. Failure to follow this caution can result in personal
injury.
Freeze Guard Procedure
1. With the truckmount turned off and the incoming water line disconnected, open
the water box drain valve on the front of the truckmount. Allow the system to fully
drain.
2. Add 2 gallons of 50/50 antifreeze and water mix to the water box.
3.
Attach a section of solution hose to the outgoing solution fitting on the front of the
machine. Attach the opposite end to the recirculation fitting. (If more sections of
hose are to be freeze guarded, attach those inline.)
4. Start the truckmount and allow it to run for 2 - 3 minutes. This will distribute antifreeze
solution throughout the truckmount.
5. Remove the chemical feed line from the chemical jug. Turn the “CHEMICAL
SYSTEM” valve to “PRIME.” This will vacuum the chemical remaining in the lines to
the recovery tank.
6. Remove the quick connect from the truckmount.
7. Spray the antifreeze and water mix out of the truckmount and into a container to
reclaim the solution. Run the solution until it stops.
8.
The truckmount is now freeze guarded. Remember to flush antifreeze from the
system prior to carpet cleaning. See the following procedure.
The reclaimed antifreeze solution may be used three times before being discarded.
