General Considerations - Astralpool Heliox UV MP Manuel D'installation

5. INSTALLATION:_________________________________________________________________________________________________

5.1. General considerations


In order to guarantee a good state of conservation, the HELIOX UV MP system must be installed in a dry and well ventilated place
at the technical room. The protection degree of HELIOX UV MP systems does not allow outdoor installation.

The temperature at the installation area must be within 35
80%.

Install the unit as far away as possible from any storage of chemical products and sources of moisture.
Warning
Beware of corrosive atmosphere formation due to pH decreasing solutions (specially, those
ones based on hydrochloric acid "HCl"). Do not install the HELIOX UV MP system near to any
stores of these chemicals. We strongly recommend the use of chemicals based on sodium
bisulphate or diluted sulphuric acid.
5.2. Installation of the UV reactor
The reactor of HELIOX UV MP systems can be installed both horizontally and vertically, as shown in the recommended installation diagram
(Figs. 1a/b).
Warning
If the UV reactor is installed horizontally, the lamp must always remain horizontal to the ground,
as if it is installed so that the lamp is vertical, in the case of low flow, an air chamber may be
formed on its top, thus becoming part of the bulb exposed. Given the high working temperature
of medium pressure lamps, it is easily understandable that this situation should always be
avoided.
If the UV reactor is installed horizontally, sensors must remain in the upper part.
Observe flow direction indications located on the UV chamber.
The reactor of the HELIOX UV MP systems is made of AISI 316 L stainless steel within which the UV lamp is housed. The HELIOX UV MP
system should always be installed after the filtration system, and before any other device in the installation such as heat pumps, control
systems, dosage systems, salt electrolysis systems, etc.
The installation of the UV system should allow easy access to the UV lamp by the user. The location of the HELIOX UV MP system must
have an effective dimensions that allow the complete removal of the UV lamp from the sleeve (approximately one meter on each side of the
connection boxes of the UV lamp).
It is highly recommended to install the HELIOX UV MP system in a place of the pipe that can be easily isolated from the rest of the installation
by two valves, so that the tasks of maintenance can be carried out with no need of partial or total draining of the swimming pool. Where the
system is installed on a by-pass (recommended option), a valve to regulate the flow must be introduced.
Warning
Prior to the installation or replacement of any system component make sure it has been
previously disconnected from the mains, and there is no water flow through it. Use only spare
parts supplied by AstralPool.
UV chamber grounding must be made in the two bonding lugs marked
using No. 8 AWG (US) and No. 6 AWG (Canada) solid copper conductor and secured to the
chamber by paint breaking washers and nuts.
