General Description

UV Disinfection

The germicidal effects of ultraviolet (UV) radiation with wavelengths around 260 nm have been known for over 100 years. The use of UV has become
more popular in recent years, since it has several advantages over chemical disinfection methods.
UV hardly alters the physical/chemical composition of the water, it is effective against any type of micro-organism (algae, bacteria, viruses, spores, yeast, etc.), and its use reduces the risks associated with handling and dosing potentially hazardous chemical products. UV treatment also minimizes the levels of combined chlorine in the pool water leading to significant water savings (by reducing the volume and frequency of water replacement in the swimming pool). The UV LP treatment system should operate while the pool’s filtration system (pump and filter) is running.
The UV LP treatment system, together with the maintenance of correct chlorine levels in the pool water, guarantees its healthiness.

The UV LP treatment systems have been designed and manufactured using the most advanced technology in UV water treatment, to guarantee long-term operation with minimum maintenance.

Product Specifications

The UV LP treatment systems are designed and manufactured with the latest technology in UV treatment of water, thus ensuring continuous operation and minimal maintenance.

Pool Water Conditions

Recommended Limits

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 94%

If the level of any of these parameters is outside the recommended limits, we recommend a suitable preliminary treatment be applied to correct them.
Balance the pool water. Correctly balanced water will produce a more efficient treatment and a lower concentration of free chlorine in the water, which will extend the operating life of the lamp and less lime scale deposits on the quartz housing in the system.

• pH should be 7.2-7.6
• Total alkalinity should be 60-120 ppm

Installation

Installation Requirements
The UV LP system should always be installed VERTICALLY on the floor, as shown below.

• The UV LP system must be installed in a dry and well-ventilated location (either indoor or outdoor).
• The temperature at the installation area must be within 36°F (2°C) and 104°F (40°C) and the relative humidity should 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 (such as hydrochloric acid “HCl”). Do not install the 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.

UV Reactor Installation

The UV LP reactor is made of AISI 316 L stainless steel and houses the UV lamp. The UV LP reactor must 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 UV LP system must have an effective dimension 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 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 main power supply and there is no water flow through it. Use only spare parts supplied by Jandy.

• Bonding and Grounding
  The National Electrical Code® (NEC® in the United States) or the Canadian Electrical Code (CEC in Canada) requires pool equipment to be bonded to each other. Check your local codes to determine if the NEC or CEC and/or other local installation codes are enforced by the Authority Having Jurisdiction (AHJ in the United States) or the local competent authorities in Canada. A solid, copper 8.37 mm2 (8 AWG) wire is required per the NEC, and 13.3 mm² (6 AWG) per the CEC, for bonding the equipment to a permanent bonding connection that is acceptable to the local AHJ or the local competent authorities in Canada. Refer to your locally enforced codes for the acceptable bonding wire gauge.
  Connect to the bonding point located on the power center and UV reactor to a common bonding point. Do not use the Jandy equipment as the common bonding point. Each piece of non-related pool equipment requiring a ground should also be bonded to the common, approved bonding point.
  National Electrical Code® (NEC®) requires bonding of the pool water. Where none of the bonded pool equipment, structures, or parts are in direct connection with the pool water; the pool water shall be in direct contact with an approved corrosion-resistant conductive surface that exposes not less than 5800 mm² (9 in²) of the surface area to the pool water at all times. The conductive surface shall be located where it is not exposed to physical damage or dislodgement during usual pool activities, and it shall be bonded in accordance with the bonding requirements of NEC Article 680. Refer to locally enforced codes for any additional pool and spa bonding requirements.

Electrical Connections

• Install the control panel vertically on a rigid surface (wall) so that the touchscreen on the front panel is at eye-level.
• 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.

Both the power of the JUV 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 JANDY authorized technician.

WARNING

Use copper conductors only. Permanently connected.

WARNING

Before the installation or replacement of any system component, make sure it has been previously disconnected from the main power supply and there is no water flowing through it.
Check all the electrical connections are well tightened to avoid false contacts and their consequent overheating.

Operation

UV LP treatment systems are equipped with a touchscreen on the front of the control panel, which allows full control of the treatment process and power to the UV lamp and the main system on/off switch.

Initial Start-up

1. Check the filter. Make sure that the filter is 100% clean.
2. Check the water chemistry. Make sure water chemistry levels are within the recommended limits before operating to ensure the UV LP system can perform with maximum efficiency. There should be no copper, iron, or algae in the pool.
3. Balance the pool water. Correctly balanced water will produce a more efficient treatment with a lower concentration of free chlorine in the water and extend the operating life of the lamp with less limescale deposited on the quartz housing in the system.
4. Check pipe connections are correct and free of leaks.
5. Allow water to circulate for several minutes to flush any air and dirt from inside the UV reactor.
6. Turn the system on with the ON/OFF switch located on the back panel of the unit.

IMPORTANT

Always connect the unit to a circuit protected by an RCD. Never look directly at the UV lamp when it is turned on. Never connect the system when the lamp is out of the reactor. Do not operate the system at a flow lower than 88 gpm.
