Freeze Guard
VACUUM FREEZE GUARD PROCEDURE:
To freeze guard your machine:
1. Start the machine.
2. Spray all of the water out of the system until the engine stops.
3. Add a half gallon of 50/50 antifreeze and water mix to the chemical
mix tank and draw the antifreeze into the flow meter.
When using the recirculation kit (part no. 078-
058) , fill a third of the mix tank with a 50/50
antifreeze mix. Verify that the upper float is not
lying horizontal,but floats below.
Attach the recirculation fitting provided in the kit
to the garden hose quick connect (see Fig. 4-1)
and this combination to the front of the machine.
Attach one section of female/female solution hose
to the outgoing solution fitting on the front of
the machine and the other end to the garden hose
and recirculation fitting combination that is attached to the front of the machine(or as
many sections as you want, if you wish to freeze guard your hoses).
4. Start the machine. Allow it to run for 2 to 3 minutes.
With the recirculation kit , skip ahead to step 6.
5. Remove the quick connect fitting from the end of the garden hose.
Attach the garden hose quick connect to the machine. Using a vacuum
hose attached to the recovery tank, vacuum the water out of the
garden hose quick connect.
