This protects the vacuum pump from water damage. Note: Waste tank level shut off will not shut the unit off due to high levels of foam. The use of a quality de-foamer is recommended. P a g e | 25 108268/49-053 Rev M LEGEND BRANDS MODEL APEX 570...
The chemicals then flow through the chemical metering valve to the solution outlet. This valve controls the rate of flow of chemical into the cleaning solution, which is indicated on the flow meter. P a g e | 26 108268/49-053 Rev M LEGEND BRANDS MODEL APEX 570...
This section of the operator’s manual explains how to prepare, start, operate, shut down and maintain your Sapphire Scientific model Apex 570 mobile cleaning unit. The model Apex 570 unit is easy to operate, however only trained operators should proceed.

Page 36
This valve must be maintained in accordance with the maintenance table in this manual. 9. VACUUM INLET HOSE PORTS The vacuum inlets are where you connect your vacuum hoses. The Apex 570 has one 2 inch and one 2-1/2 inch ports. Always cap unused ports to maintain proper vacuum levels.
Page 37
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.

For heavily soiled carpets, the wand may be used in a scrubbing action, with chemical solution applied in both push and pull strokes, provided that the final stroke is a pull stroke with no chemical injection. P a g e | 33 108268/49-053 Rev M LEGEND BRANDS MODEL APEX 570...
Page 39
DUAL WAND OPERATION The model Apex 570 has sufficient capacity for dual wand operation with minimal pressure loss at each wand. The pump pressure and temperature can remain at the same levels as for single wand operation. The chemical flow rate may be set slightly higher than for single wand operation.
Page 40
NOTE: The setting is also dependent on the type of chemical used and the concentration ratio of chemical to water. Always use the LOWEST flow rate that properly cleans the affected areas. Excessive chemicals can cause damage to the items being cleaned. P a g e | 35 108268/49-053 Rev M LEGEND BRANDS MODEL APEX 570...
