Choosing a Site
Choose a site with a rm base and as close to the water source as possible with
correct power supply. Make sure your pump is always connected to an adequate,
reliable source of clean water.
Housing your SJ Silver Series Jet Pump
To protect your pump from the weather, make sure the cover provided is water proof,
frost free and has adequate ventilation.
The pump should be horizontally mounted on a rm base allowing for drainage, to
avoid damage to ooring etc., that over time may occur from leaking pipe joints or
pump seals. Do not mount the pump vertically.
WARNING: Some insects, such as small ants, nd electrical devices attractive for various reasons. If your pump
enclosure is susceptible to insect infestation you should implement a suitable pest control plan.

Power Connection
The pump motor is tted with an earthed three pin plug & lead.
The installer is responsible for the correct connection of the electrical supply to the pump motor.
• Make sure the supply voltage and frequency is the same as the nameplate.
• Make sure that there is a sound earth connection available.
In accordance with AS/NZS 60335.2.41 we are obliged to inform you that this pump is not to be used by children or inrm
persons and must not be used as a toy by children.
POWER CONNECTION
Connect lead to power supply designated on pump label. Do not use long extension leads as they cause
substantial voltage drop, poor pump performance and may cause motor overload.
EARTH CONNECTION
The pump power lead includes an earth pin on the plug, which MUST be correctly connected to a suitable earth
on the electrical supply.
Electrical Power Surge Protection
An electrical power surge or spike can travel on the supply lines and cause serious damage to your electrical equipment.
The Presscontrol tted to this pump has a metal oxide varistor (MOV) tted to help protect it’s circuit. This MOV is a
“sacricial” device, meaning that it effectively gradually destroys itself every time it takes a surge. The MOV is not a
lightning arrestor and may not protect the Presscontrol if lightning or a very powerful surge hits the pump unit.
If the installation is subject to electrical power surges or lightning we strongly recommend the use of a suitable surge
protection device on ALL electrical equipment.
Pipe Connections
For best performance use P.V.C. or polythene pipes at least the same diameter as the pumps inlet and delivery outlet
openings. Larger diameter pipe may be used to minimise resistance to ow when pumping longer distances.
Use unions as pipe connections to enable easy removal and servicing. Use sufcient tape to ensure airtight seal and
hand tighten only. To prevent strain on pump threads always support heavy inlet and outlet pipes. If there is a likelihood
the water supply may contain solid particles such as pieces of plant or vegetable matter, a suction strainer should be
installed before the pump to avoid blocking of the pump. Lay suction pipe at a constant gradient to avoid air pockets
which reduce pump efciency.
NOTE - Suction leaks are the largest cause of poor pump performance and are difcult to detect. Ensure all
connections are completely sealed USING THREAD TAPE ONLY.
Installations with a Suction Lift
Installations with a suction lift require a good quality foot valve to avoid loss of prime.
For model SJ35-04P2C/LOP the enclosed suction check valve can have a suction strainer tted and used as a foot valve.
Installations with Flooded Suction
Installations with ooded suction require a gate valve so water supply can be turned off for pump removal and servicing.
Model SJ35-04P2C/LOP must have the enclosed suction check valve tted with the enclosed nipple directly into the
pump inlet. Ensure the check valve is installed in the correct direction to allow ow into pump inlet.
WARNING
DO NOT RUN DRY.
DO NOT RUN WITH LOSS OF PRIME.
DO NOT PUMP WATER CONTAINING ABRASIVE MATERIALS.
~ 3 ~
Abrasive Materials
The pumping of abrasive materials will cause damage to the pump which will then not be covered by the guarantee.
Water temperature in pump must not exceed 45oC, or damage caused will not be covered by guarantee.
Connection of Mains Scheme or Town Water Supply to either Suction or
Discharge of Pump
Most Water Supply Authorities have strict regulations regarding
direct connection of pumps to mains water supplies. In most
cases an isolating tank is required between mains supply and
pump. This is also the recommend method for this pump.
Directly applied mains pressure can exceed pump operating
pressure and damage pump.
Davey Products Pty Ltd can not accept
responsibility for loss or damage resulting from
incorrect or unauthorised installations.
NOTE - If connecting your SJ Jet Pump direct to mains water, the casing pressure (maximum outlet pressure)
must not exceed 600kPa (6bar/87psi).
Priming and Operation
SJ35-04 Manual Pump
1. Fill pump and suction line through the pump discharge or priming port (on ooded suction, simply open
gate valve to pump).
2. Ensure outlet nearest to pump is open.
3. Ensure all valves in suction line are open and switch on pump at power outlet.
4. Prime should establish almost immediately and a strong ow of water should be evident from
the outlet. Allow water to ow for 10-20 seconds to expel air then close outlet and switch off
pump.
5. If no ow is evident from tap, switch off at power point and repeat from step 1 ensuring there is an
adequate supply of water available to the pump.
SJ35-04P2C/LOP Automatic Water Pressure System
1. Fill pump and suction line through the pump discharge or priming port (on ooded suction, simply open
gate valve to pump).
2. Ensure outlet nearest to pump is open.
3. Ensure all valves in suction line are open and switch on pump at power outlet.
4. Slide “start switch” on pressure switch until pump maintains pressure.
5. Prime should establish almost immediately and a strong ow of water should be evident from
the outlet. Allow water to ow for 10-20 seconds to expel air then close outlet. Pump will
switch off shortly after and wait in standby until a drop in pressure initiates a pump start.
6. If no ow is evident from tap or the pump does not automatically restart on pressure drop (tap is re-
opened) switch off at power point and repeat from step 1 ensuring there is an adequate supply of water
available to the pump.

2. Ensure outlet nearest to pump is open.
3. Ensure all valves in suction line are open and switch on pump at power outlet. There will be
a delay of less than 1 second before the pump starts.
4. Prime should establish almost immediately and a strong ow of water should be evident from
the outlet. Allow water to ow for 10-20 seconds to expel air then close outlet. Pump will
switch off shortly after and wait in standby until a drop in pressure initiates a pump start.
5. If no ow is evident from tap, switch off at power point and repeat from step 1 ensuring there is an
adequate supply of water available to the pump.
6. If the pump does not automatically restart on re-opening of tap, consult trouble shooting guide.
Automatic Controllers
SJ35-04P2C/LOP Automatic Water Pressure System
This model uses an exclusive “loss of prime” pressure switch. To start (cut-in) on pressure drop, stop on high pressure
and shut down on extra low pressure or “loss of prime” (30kPa below the cut-in pressure).
The SJ35-04P2C/LOP is also equipped with a special ow restrictor in the discharge to ensure the system will not engage
the “Loss of Prime” protection feature unnecessarily. This ow restrictor is cast into the discharge tee assembly.
Cut-in Pressure Cut-out Pressure LOP shut down pressure
(kPa) (kPa) (kPa)
Factory Settings 140 280 110
Starting
Initial starting, and restarting the pump after a water supply failure is
detected, is achieved by holding the sliding “start switch” until operating
pressure above the LOP shut down pressure is obtained.
Ensure the pump is correctly primed and connected to the correct power
supply.
Once the pump has been correctly started, it will continue to cycle on and off
according to the pressure demands placed on the system.
Adjustment of Pressure Switch
(For lifts of 1.5m or over)
This adjustment should only be carried out by a suitably qualied and authorised person.
Your Davey dealer would be happy to assist.
1. Switch off pump and unplug it from power point.
2. Remove pressure switch cap.
3. Turn Adjusting screw, (A) 1/2 turn anticlockwise.
4. Replace cap and switch on pump.
5. If pump cuts out, adjustment is now complete.
6. If pump does not cut out after step (4), repeat steps (1) to (5).
~ 5 ~
Pressure Tank Maintenance (SJ35-04P2C/LOP only)
The only regular attention your new pressure system requires is to check the pressure tank’s air
charge every 6 months. This is ‘factory set’ at 125kPa (18psi) and can be checked at the air valve
with a tyre gauge.
CAUTION: Do not charge tank to a higher pressure than 125kPa.
To check air pressure in tank:
1. Switch off pump.
2. Open outlet nearest to pump to release water pressure.
3. Remove air valve cap from top of Supercell tank and charge tank to 125kPa (18psi) using
air pump and check with tyre gauge.
4. Switch on.
5. Close outlet.
Your SJ35-04PC & SJ60-08PC pump is tted with a Presscontrol. This device will automatically stop and start your
pump, depending on ow demand. Please read the enclosed presscontrol instructions carefully for full details as to its
function.
Never operate your pump for more than several seconds without discharge ow.

C) in pump enclosure.
WARNING - When servicing or attending pump, always ensure power is switched off and lead unplugged.
Electrical connections should be serviced only by qualied persons.
Care should also be taken when servicing or disassembling pump to avoid possible injury from hot
pressurised water. Unplug pump, relieve pressure by opening a tap on the discharge side of the pump and
allow any hot water in pump to cool before attempting to dismantle.
During servicing, use only approved, non-petrochemical based oring and gasket lubrication. If unsure, consult
your Davey Dealer for advice.
