Fast System Freeze Protection - Tennant 5400 Manual De Operador

FaST SYSTEM FREEZE PROTECTION

FaST Winterizing Kit #613898 is required.
1. Disconnect the FaST--PAK from the system and
connect the quick--disconnect fitting, supplied with
kit, to the inlet line of the concentrate pump.
2. Using a small cup, drain as much of the FaST
concentrate from the inlet line as possible
(Figure 75). If the concentrate does not flow out of
the line, simply squeeze and release the inlet hose
several times.

3. Install the hose, supplied with kit, onto the fitting.
Using a small cup, pour RV antifreeze into this
hose until inlet line and hose are full. If the
antifreeze does not flow through the coupling,
squeeze and release the inlet line several times
(Figure 76).

4. Tape the inlet hose to the side of the FaST--PAK
holder to keep the hose vertical (Figure 77). Run
the machine in the FaST mode until there is no
foam coming from the machine. This indicates the
RV antifreeze has been flushed through the
concentrate pump. This step could take anywhere
from 5 to 10 minutes depending on how much
FaST concentrate was left in the inlet line after
draining.

5. Drain the solution tank and remove the
water strainer cup located under the
machine. Leave the cup and strainer off of the
machine, and operate the machine in the FaST
mode for 1–2 minutes. Clean the strainer if
needed and reinstall strainer and cup to machine
(Figure 78).

6. Remove the kit's quick disconnect fitting and hose
from the concentrate pump inlet line. Connect the
inlet line to the storage plug on the FaST--PAK
bracket. This will prevent any contaminants from
entering concentrate system (Figure 79).
