Prior to assembling the unit make sure the following are completed or
verified:
F
All vacuum fittings must be clean and free of foreign material.
F
Lightly coat all O-rings and seals with a thin film of high vacuum
grease before installation.
F
KF clamps are supplied with wing nuts and should never e tightened
more than finger tight. Do not use tools to tighten.
F
Change the oil in the vacuum pump.
CAUTION: REMOVE the exhaust port blanking flange prior to
operating the pump. Operating the vacuum pump
with the exhaust port blanking flange installed can
cause permanent internal damage to the pump.
1. Remove the cable ties that fasten the pump intake filter assembly to
the frame.
2. Remove the vacuum system parts from the boxes inside the system
and the shipping crate.
3. Remove the flexible membrane and spacer from the pump inlet KF-25.
4. Remove the blanking flange from the vacuum pump exhaust port.
5. Attach the pump intake filter onto the vacuum pump inlet port and
secure with a KF-25 centering ring and a KF-25 clamp. Verify that
the flow arrow on the filter body points away from the pump and that
the IN port connects to the pump.
6. Attach the throttle valve assembly to the pump intake filter. The
pump side of the valve should be oriented toward the vacuum pump.
Verify that the filter can be changed without a complete disassembly.
7. Attach the vent valve to the throttle valve assembly. Orient it with
solenoid opposite pump side of the throttle valve and approximately
parallel to the bellows. Secure the VCO fitting using a wrench.
Apply a light coat of vacuum grease to the O-ring on the vent valve.
8. Attach the vacuum switch to the throttle valve. Using a wrench
secure the VCO fitting. Apply a light coat of vacuum grease to O-ring
on the vacuum switch.
9. Attach the bellows between the throttle valve and the chamber.
Adjust the location of the pump intake filer and the throttle valve
assembly as necessary. There should be minimum flexing of the
bellows. Secure the bellows with 2 KF-40 centering rings and KF-40
clamps.
10. Attach the exhaust filter housing with a housing O-ring and tighten
the KF-25 clamp to retain it. Orient it with the drain plug facing the
side of the machine.
11. Remove the drain plugs and install the oil return fitting. Use the
existing drain plug washer with the new fitting.
12. Attach the oil return line that connects the oil return solenoid and
