3-3: Machine Maintenance
FREEZE GUARDING THE TILE SYSTEM
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 to 3 minutes. This will distribute antifreeze
solution throughout the truckmount.
If using the recirculation kit, skip ahead to step 6.
5. Remove the quick connect from the truckmount.
6. Spray the antifreeze and water mix out of the truckmount and into a container to
reclaim the solution. Run the truckmount until there is no more solution coming from
the truckmount.
7. 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.
To freeze guard the hoses and wand perform step 6 with the items to be freeze
guarded attached.
Recovering Antifreeze for Re-Use
1. Attach all hoses and wands which have been freeze guarded to the truckmount.
2. Attach the incoming water source to the front of the truckmount.
3. Start the truckmount.
4. Spray the solution through the hoses and wands into a sealable container until all
signs of antifreeze are gone.
