STARTING THE UNIT
1.
Set throttle control, pull out engine choke, turn pressure pump switch to OVR and turn ignition key to start.
2.
Push in engine choke after engine has started.
3.
Set throttle control to desired speed.
4.
Turn the water pump switch to the ON position.
NOTE: If the unit does not build water pressure after 5 seconds, check fo
r adequate water supply. See “Loss of Water
Pump Pressure in the Troubleshooting section of this manual.
VACUUM HOSE
Connect the vacuum hose(s) to the vacuum inlet connection at the front of the unit. Connect the opposite end of the
vacuum hose(s) the cleaning tool. Let the unit run for a few minutes with the vacuum inlets partially blocked off to warm
up the cleaning solution.
Sapphire Scientific recommends that the total floor tool size does not exceed #6. Using larger jet sizes on your model
Apex 570 unit may reduce cleaning temperatures.
PRIMING THE CHEMICAL PUMP
NOTE:
Sapphire Scientific recommends that the chemical pump be primed whenever the water pump is on. This
eliminates possible pressure fluctuations and water pump pulsations related with running the chemical pump dry
1.
Insert the chemical prime tube and the chemical inlet tube into the chemical container.
NOTE:
When inserting the chemical tube into the chemical container, ensure that it stays submerged, as the chemical
pump will not function if air is allowed to enter the inlet line.
2.
Turn the 3-way chemical selector valve located on the control panel to the PRIME position. The chemical will
then flow from the chemical container through the chemical prime tube into the vacuum system.
If the pump does not prime, then:
Seal off the vacuum port. The vacuum will quickly draw chemical from the chemical container. After the flow begins,
turn the chemical selector valve to OFF position and turn the chemical selector valve back to the PRIME position and
continue the procedure.
3.
When the chemical flows with no air bubbles, priming has been achieved. Turn the chemical selector valve from
PRIME to METER. With the cleaning tool open, check the flow meter and adjust the chemical metering valve
until the desired rate of chemical flow is achieved.
