The germicidal effects of ultraviolet light (UV) with wavelengths around 260 nm are well known for over 100 years. Its use has been
increasing in recent years as it presents a number of advantages over chemical disinfection systems, since virtually UV light no alters
the physical and chemical composition of water, it is very effective against any type of microorganism (algae , bacteria, viruses, fungi,
yeasts, etc.) further minimizing the risks of handling and dosing of potentially hazardous chemicals. Moreover, UV treatment reduces the
levels of combined chlorine in water, thereby producing significant water savings by reducing the volume and frequency of renewal of
pool water.
The HELIOX UV LP treatment system in addition to maintaining a certain level of chlorine in water, ensure the sanitary quality of pool
water. The HELIOX UV LP treatment system will operate when the pool recirculation (pump and filter) is operational.
The HELIOX UV LP treatment systems are designed and manufactured with the latest technology in UV treatment of water, thus
ensuring continuous operation and minimal maintenance.

WARNING: when installing and using electrical equipment, basic safety precautions
should always be followed, including the following:
READ AND FOLLOW ALL THE INSTRUCTIONS
A yellow-green wire connector marked (*) is provided on this unit to
connect a minimum No. 8 AWG for US (UL) and a No. 6 AWG for Canada
(CSA) solid copper conductor between this unit and any metal equipment,
metal enclosures of electrical equipment, metal water pipe or conduit
within 5 feet (1.5 m.) of the unit.
Two bonding lugs marked (*) are provided on the final ends of the UV
chamber suitable for No. 8 AWG (US) and No. 6 AWG (Canada) and
secured to the chamber by paint breaking washer and nut.
(*) IEC 60417, symbol 5019
This product must be connected to a circuit protected by a ground fault
circuit interrupter.
Pool end use. Do not use this system to a different application for which it
was designed.
The equipment should be installed and handled by truly qualified people.
Current electrical and accident prevention regulations should be followed.
Under no circumstances will the manufacturer be held responsible for the
assembly, installation or start-up, nor any handling or fitting of
components unless they are carried out on its premises.
Check all the electrical connectors are well tightened to avoid false
contacts and their consequent overheating.
Install the control panel so that the cooling grids (if exist) are not
obstructed.
For indoor use only. This unit is not intended for outdoor use.
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.

4
Never remove the lock nut of the quartz sleeve when the water is
recirculating through the UV reactor as it could be expelled and causing
damage.
The UV light generated by this equipment can cause serious damage if
the eyes or skin are exposed directly to the lamp. Never connect the
system when the lamp is out of the reactor.
Do not handle the UV lamp until completely cold.
Always handle the UV lamp with gloves, as fat and other impurities
deposited on the surface may reduce its performance and durability. In

5. INSTALLATION:_____________________________________________________________________________________________
5.1. General considerations
 In order to guarantee a good state of conservation, the HELIOX UV LP system must be installed in a dry and well ventilated
place at the technical room. The protection degree of HELIOX UV LP systems does not allow outdoor installation.
 The temperature at the installation area must be within 36oF (2oC) and 104oF (40oC) and the relative humidity must not exceed
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 LP 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 LP systems must be installed VERTICALLY, as shown in the recommended installation diagram (Figs. 3).
Warning
Observe flow direction indications located on the UV chamber.
The reactor of the HELIOX UV LP/LP+ systems is made of AISI 316 L stainless steel (codes 60344, 60345, 60346 and 60347) or
polyethylene (codes 60348,60349,60354 and 60358) within which is housed the UV lamp.. The HELIOX UV LP 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 LP system must
have an effective dimensions that allow the complete removal of the UV lamp from the sleeve (approximately 1 m above the reactor
cover).
It is highly recommended to install the HELIOX UV LP 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 (*) on the end
flanges using No. 8 AWG (US) and No. 6 AWG (Canada) solid copper conductor and
secured to the chamber by paint breaking washers and nuts (Fig. 2).

5.3. Installation of the control panel
 Always install the CONTROL PANEL of the HELIOX UV LP system vertically and on a rigid surface (wall), so that the
touchscreen located on the front panel is at the level of the eyes.
 Cooling fan and grids (if exist) must not be blocked.
Warning
The equipment should be assembled and handled by truly qualified people.
Current electrical and accident prevention regulations should be followed.
Do not attempt to alter the system to operate at a different voltage.

8
Both the power of the HELIOX UV LP system control panel and the interconnection of the UV lamp and the sensors must be made at the
terminal block at the base inside the control panel. The control panel base has a series of cable glands for the correct fixation of the
power cables and sensors. In any case the length or section thereof should be amended, without first consulting an AstralPool
authorized technician.
Warning
Use copper conductors only.
Permanently connected.

5.4. UV lamp connection
Connect the UV lamp(s) installed within the UV reactor to the corresponding terminals on the control panel using the cables supplied
with the unit (LP-0XX/n) (see page 8-10). To do this, remove the cover on the top of the UV reactor, and connect the wires to the
corresponding terminals:
Fig .5
1.- LP-045 lamp power cables (black wires labelled “1” to “4”. Wire number must exactly match the number of the terminal block as
shown in the following figure).
2. LP-025-M microswitch cable (black wires, labelled “1” and “2”. Wire relative position is not relevant).
Warning
Unit is equipped with an automatic mechanism (micro-switch) for shutting off the power of
the UV lamp whenever the cover is removed.
Once the connection is made, close the UV reactor head.
Should also connect the ground wire to the TWO bonding lugs marked (*) on the final ends of the UV chamber suitable for No. 8 AWG
(US) and No. 6 AWG (Canada), and secure to the chamber by paint breaking washer and nut.
Fig. 6
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.

6034E104-21
13
Check all the electrical connectors are well tightened to avoid false contacts and their
consequent overheating.
5.5. Installation of the external flow detector
1. Vertically install the FS-1 flow detector (flow switch) supplied with the unit using a ¾” male threaded saddle (Fig. 7a).
2. There is an arrow on the head of the flow detector. Make sure that this arrow is parallel to the pipe shaft and pointing in the
direction that the water flows (Fig. 7b).
3. Do not install the flow detector near magnetic objects. They could affect the operation of the magnetic device it contains and
reduce its reliability.
Fig. 7a Fig. 7b
Connect the FS-1 flow-switch to the corresponding terminals at the terminal block inside the control box. (see page 8-10).
5.6. Controls and indicators
The HELIOX UV LP treatment systems are equipped with a touchscreen located on the front of the control panel, which includes an
advanced software that allows full control both on the treatment process and on the power of the UV lamp. Also on the front panel it is
the main switch of the system.

14
5.7. Start-up
1. Make sure the filter is clean to 100%, and that the pool and the installation does not contain copper, iron and algae.
2. The analytical condition of the water is very important to ensure that the HELIOX UV LP system works with the highest levels of
effectiveness. Before starting the system check that the following parameters are within the recommended levels:
 Iron: less than 0.3 mg./l.
 Hardness: less than 120 mg./l.
 Turbidity: less than 1 NTU.
 Manganese: less than 0.05 mg./l.
 TSS: less than 10 mg./l.
 UV Transmittance: higher than 95%.
If the levels of any of these parameters exceed the recommended values is recommended to do a proper pre-treatment to correct them.
3. Balance the pool water. This allows us to obtain a more efficient treatment with a lower concentration of free chlorine in the water, and
a longer operating of the lamp in addition to a lower calcium scaling on the quartz sleeve.
a) pH must be in the range 7.2-7.6
b) Alkalinity must be in the range 60-120 ppm.
4. Check that all hydraulic connections are properly assembled and that there are no leaks in any of them.
5. Let recirculate the water at least for a few minutes to evacuate air and any dirt that might be inside the UV reactor.
6. Connect the system using the main switch [2] on the front side of the control panel (Fig. 1).
Warning
Never connect the system when the lamp is out of the reactor.
For units with POLYETHYLENE reactor:
