5.0 Set-Up and Operation Continued
5.4 Power Priming the High Pressure Pump
Once water is in the solution tank, the high pressure pump must be primed:
• Turn ON both vacuums then the solution pump. The
vacuum will pull solution through the pump and prime
valve into the vacuum tank.
• Place the end of priming hose inside the vacuum hose barb.
• Cup a hand around the hose and barb to increase the
vacuum suction on the hose. When the pump is primed, you
will hear the pulsation of the pump change.
• After priming, turn OFF the solution pump. If you have not
yet connected your solution hose or tool, you may have to
relieve the pressure in the line so you can connected your
hose or tool.
If the pump still does not prime or if flow is low or unsteady,
check the hose from the solution tank to the pump (as well as the filter) for clogging,
kinks or restrictions. Clean or replace hose and/or filter and repeat the priming process.
If you are having trouble with the pump, refer to the “Trouble Shooting Guide” section or
contact your distributor for advice or assistance.
5.5 Connection of Vacuum Hoses
There are three (3) components used to connect the cleaning tool to the vacuums and
recovery tank:
1. 4-Foot Vacuum Hose: connected to the vacuum barb on the front of the machine and
to the outlet side of the clear view in-line filter.
2. Clear View In-Line Filter
3. 25-Foot Vacuum Hose: the 2” cuff on the 25-foot vacuum hose is connected to the
inlet side of the clear view in-line filter The other end with the 1-1/2” cuff is connected
to the cleaning tool.
When ready to being cleaning, turn both vacuum switches to the ON position. While
the Hard Surface Extractor can operate with only one (1) vacuum for cleaning delicate
fabrics, in most situations you will turn both vacuums switches to ON.
