Storage Prep and Freeze Protection Procedures:
Your Olympus M1200 must be protected from freezing. Freezing can cause serious damage to the pump,
pump-out, auto-fill float valve, and any other component containing water. If the M1200 is transported or
stored in freezing temperatures, the following procedures should be performed.
ALSO, if the M1200 is stored for an extended period of time, the following procedure should be performed
to prevent the pump seals from drying out.
1. In a separate container mix 1/2 gallon of water with 1/2 gallon of automotive radiator anti-freeze.
(Ethylene glycol type). Mix well and pour into the solution tank.
2. Connect the pump prime hose to the solution outlet (female quick connect) and perform the pump
priming procedure, directing the flow back into the solution tank. When the pump is primed, turn the
pump off and disconnect the priming hose.
3. Connect the HP solution hose to the solution outlet (female quick connect.) Connect the opposite end of
the HP solution hose to the Auto-Fill inlet (male quick connect.) Leave the chemical feed hose in the
solution tank and ensure the check valve filter is submerged in the anti-freeze solution. To speed the
process the metering tip can be removed. Turn the pressure regulator knob counter-clockwise to lower
the pressure to 100psi or lower
CAUTION: Applying high pressure (over 100psi) to the Auto-Fill system will cause damage to
the Float valve and chemical proportioning mechanism.
4. Turn the solution pump switch to the ON position. Allow the anti-freeze to circulate for 5-10 minutes.
Mix and add more anti-freeze solution as needed. Make sure end of chemical feed hose stays submerged
in the anti-freeze solution. This will assure that the anti-freeze will be drawn into the proportioning valve.
5. Connect any cleaning tools that will be stored with the M1200. Direct tool spray back into the solution
tank or into a bucket. Repeat for all tools to be protected.
6. Turn the solution pump switch to the OFF position.
7. Use the 4’ short section of vacuum hose to vacuum the remaining anti-freeze solution out of the solution
tank and bucket.
8. Remove the cap from the waste-pump out outlet fitting on the back of the machine. Connect a hose to a
drain or hold a bucket up to the fitting to catch the pump-out flow.
9. Remove the lid from the recovery tank. Turn the Waste Pump switch to the ON position and lift the float
switch to engage the pump-out. Lower the float and turn off the Waste Pump Switch as soon as you see
anti-freeze flowing from the outlet fitting or hose.
10. Drain the remaining anti-freeze solution from the recovery tank and the machine is ready for storage.
RETURNING THE M1200 TO SERVICE AFTER STORAGE OR
FREEZE PROTECTION:
To return the M1200 to service, the anti-freeze must be flushed from the machine. Flush the anti-freeze out
of the machine by repeating the procedures above using fresh water in place of anti-freeze.
