Important Installation Check List
Your installation must have the following elements, see manual.
The top header pipe was installed with a 1 to 2° slope toward the outlet.
Aluminium channel was laid top and bottom of the collector array as shown in the manual.
Ultimate uplift wind loadings were considered and panels secured appropriately.
The stainless steel strapping was installed with sufficient play to allow for collector contraction.
The roof edge exclusion zone was observed.
A hot spot check was performed. All collectors are cool during full sun exposure (top of panels may be warmer).
The PV panel is mounted with no shading and at least 2cm clearance from its mounting surface.
The collector array faces anywhere from West to North East.
A vacuum release valve was installed off the roof 750mm below the highest point of the collector array.
The outlet is submersed in the pool/spa.
A minimum of stress is placed on the pumps inlet/outlet pipe connections.
All suction line prior to the pump is air tight and slopes up toward to the pump with no air traps.
The over-temperature thermostat was installed and tested.
The thermostat aluminium U-channel and thermostat itself is well insulated from the surroundings.
PVC plumbing lines were laid at such an angle so that all water drains from them for frost proofing.
The possibility of a drain down event caused by a failure in the Vertex plumbing lines was considered (water
should drain safely).
The appropriate pump/strainer/suction line plumbing configurations was observed.
If the return line is an “
over the t
op” type, both
the drain down event fail safes were implemented.

Further Operating Instructions
31.1
Legionaries Risk
The Vertex system must be switched off 1 hour before spa use.
Disinfectant should be
introduced and the filter pump run for at least 1 hour before spa pool use. Always follow
disinfection advice supplied by your spa pool manufacture.
If using the Vertex system for pools larger than 10m
2
we recommend that the filter
pump run at least a short period in the evening so as to help mix the warm water
deeper into the pool - otherwise the top layer of warm water will cool excessively at
night.
We strongly recommend the system be switched off during pool/spa use or when you go on
holidays. The system can be switched on after use, making sure people are away from the
outlet and that the pump is still primed.
