During cold storage, the analog pressure gauge may be damaged from freezing temperatures.
This is due to the fluid in the pressure tube freezing and over pressurizing the analog gauge.
Use the following procedure when putting the Multi Pro in cold storage.
This procedure for preparing the Multi Pro for cold storage will be added to the operator’s
manuals.
1. Drain the spray system completely.
2. Prepare rust inhibiting, non-alcohol based, RV antifreeze solution per the
manufacturer's instructions.
3. Add the RV antifreeze solution to the sprayer tank.
4. Run the spray pump for a few minutes to circulate the RV antifreeze throughout the
spray system.
5. Disconnect the red pressure gauge tube from the pressure gauge.
6. Turn the pump on and run the machine until you can see the anti-freeze at the end of
the red pressure tube.
7. Turn the pump off and leave the pressure tube disconnected from the pressure gauge
during the duration of cold storage.
8. Reconnect the pressure tube to the analog gauge when the sustained temperature is
above freezing.
NOTE: Be careful not to damage the seal on the back of the gauge. If the seal is damaged, fluid
will enter the gauge.
