2. Important safety informaon
▪Vacuum pumps are potenally dangerous if incorrectly used, repaired or
maintained. Be cauous when you do the repair or maintenance work.
▪ Any incorrectly ed spare parts could damage your pump and could be
potenally dangerous.
▪ Never allow unqualied personnel to aempt to remove or replace any part of the
pump.
▪If you have any doubts about the servicing procedures or product capabilies,
contact us.
▪Always conform to service schedules unless more frequent servicing is required
due to adverse condions.
▪Report any defect before an accident or consequenal damage can occur.
▪Observe all local and naonal regulaons, norms and guidelines.
▪Never allow anyone to remove large or heavy components without adequate
liing equipment.
▪ Before you start the maintenance work, make sure that the pump is switched o
and isolated from the mains power supply.
▪ The pump may have been exposed to processes that use hazardous substances or
produces by-products that are dangerous to human health and safety, for example,
chemically acve, biologically acve or radioacve substances.
▪ Before working on a pump, make sure that the correct personal protecve
equipment is available and being used. Always wear safety goggles. Wear a
breather mask with posive air pressure and take other precauons if you believe
the pump may be contaminated with hazardous substances and dust.
▪ When applying sealants and lubricants, prevent contact with the skin by wearing
suitable gloves.
▪ Seals may contain uoroelastomer, which when properly handled is not dangerous
but which may produce a toxic and corrosive residue (hydrogen uoride or
hydrouoric acid) in the event of excessive heat or re depending on the
circumstances of degradaon and other materials involved.
▪ On compleon of maintenance, check the pump funcons correctly and that all
guards and protecon devices are ed and working correctly and that the pump
is electrically safe.
▪If the pump is used for handling hazardous substances check the pump for leak-
ghtness before use.
▪Dispose of waste oil and any process by-products in accordance with local and
naonal safety and environmental requirements. It is usually illegal to dispose of
waste oil into drains or watercourses or to bury it.

3. Introducon
This manual provides Installaon instrucon for RV motor starng relay and RV motor
capacitor ed to the 1-phase RV pumps ed with a plasc terminal box or an
aluminium terminal box.
Refer to Replace the motor starng relay and capacitor on page 9 for the RV pump ed
with a plasc terminal box manufactured before January 2010 and the RV pump ed
with an aluminium terminal box manufactured aer January 2010.

4. Replace the motor starng relay and capacitor
4.1 Fied with plasc terminal box
1. Switch o the pump and isolate it from the electrical supply. Allow the pump to
cool to a safe temperature.
2. Refer to Figure: Remove/t the motor starng relay. Unscrew the four screws
which secure the cover to the top of the pump-motor and remove the cover.
3. Partly li the old Motor Starng Relay from its retaining slot to access the relay
terminal connecons.
4. Use a suitable screwdriver to remove the terminal connecons o of the relay.
5. Dispose of the old relay safely in accordance with all local and naonal safety and
environmental requirements.
6. Check the code on the motor starng relay to make sure that you have the new
relay (the code should be '4771xxxxxUBx', where x is any character).
7. Hold the new motor starng relay with terminals 1 and 4 at the top (that is,
nearest the motor cover) and t the terminal connecons to the terminals on the
relay as described in Table: Motor starng relay terminal connecons.
8. Slide the motor starng relay into the retaining slot. Make sure that you do not
trap any of the relay wires when you t the relay.
Note
You may have to cut the cable es which secure the relay terminal wires to allow
you to easily t the relay. On some older pump-motors, you may have to rotate the
relay with pins 2 and 3 at the top to t the cover properly.
9. Partly li the old motor capacitor to access the terminal connecons.
10. Use a suitable tool to remove the terminal connecons from the capacitor.
11. Remove the old capacitor and safely dispose of it in accordance with all local and
naonal safety and environmental requirements.
12. Check the marking on the capacitor to make sure that the new capacitor is new
(the capacitor should be 160 mf, code 'KP8174'.
13. Hold the new capacitor as shown in detail C and t the terminal connecons to the
terminals on the capacitor as described in Table: Capacitor terminal connecons.
14. Slide the new capacitor into the pump-motor enclosure. Make sure that you do not
trap any of the wires.
15. Make sure that the voltage shown on the voltage indicator corresponds with your
electrical supply voltage. If it does not, recongure the pump-motor. Refer to the
RV pump instrucon manual.
16. Use the four screws removed in Step 1 to secure the cover to the top of the pump-
motor. Make sure that you do not trap any of the wires when you t the cover.
17. Reconnect the pump to the electrical supply.
