1. Preparation for Installation
Inspect your pump for shipping damage. Report any damage to your Onga
Dealer. Make sure the suction piping is free of air leaks and is laid so that
there can be no airlocks.
Warranty of these pumps is void unless they are operated in accordance with
this owner’s manual.
2. Pump Protection
The pump should be protected from the weather, fl oods, chemicals, dust,
vermin, insects etc. It is highly recommended that the pump be housed in a
weather proof, well vented enclosure. If the pump is not adequately housed
the warranty may be deemed void.
Connection with a mains Pressure Hot Water System
The maximum pump pressure specification is 600kPa. It
is important that a reliable pressure relief valve (set to the
maximimum specifi cation or lower) is installed between the pump
control discharge and the mains pressure Hot Water Service.
Failure to install this device may lead to product damage not
covered by the manufacturers warranty.
3. Pipe Installation
Pumps can be damaged if care is not taken when connecting pipes. Pipes
should be supported so that the pump casing is not strained by the weight
or misalignment.
We recommend the pump and pipe are coupled using fl exible type polythene
pipe, rubber hose or a multi-directional barrel union. This union coupling can
also be used to remove the pump for service should it be necessary without
having to cut pipes.
Pipe fi ttings should be carefully screwed onto the pump making sure not to
cross-thread or overtighten. We recommend the use of a moulded pipe fi tting
to connect to the pump as this avoids possible damage to the pump threads
and unnecessary replacement of parts.
For best results use tefl on tape to join seal joint. Satisfactory sealing can be
achieved by hand tightening fi ttings ensuring that no leaks are evident once
under pumping pressure.
4. Locating the Pump
Find a location for your pump as close to your water source as possible.
