3. GENERAL INSTALLATION INSTRUCTION
3.1 Mounting instructions
The H.R.UV-C SPA should be either installed horizontally or vertically allowing enough space for the pipe
connections, wiring and maintenance of lamps/quartz sleeve. It should be firmly secured, using the fixing
kit provided, to a solid wall.
NOTE: When mounting the UV, it is essential to leave a clearance space of at least 1 metre
from one side of the unit to allow access to replace the lamp(s) and/or quartz
sleeve(s) when required. Both the lamps and the quartz sleeve can be replaced
from either end of the unit; if installing vertically the 1m clearance space must be
above or below the unit, if installing horizontally the 1m clearance space must be to
the left or right of the unit.
WARNING: The H.R.UV-C SPA must be installed within a dry, permanent weather-proof area. In
any case where water or moisture enters the enclosure the warranty will be void.
Caution: If the H.R.UV-C SPA is unused during the winter months; it must be drained to prevent
frost damage. Water must not be allowed to freeze inside the unit as this will cause severe
damage.
See Fig. 3 for mounting instructions when securing to the wall.

3.2 Pipe work
The H.R.UV-C SPA should be placed downstream (after) of any pumps, filters and heating devices but
upstream (before) of any chemical dosing or similar water treatment (see Figs.4 ).
Fig. 4
3.3 Flow direction
The H.R.UV-C SPA is factory set to accept input water flow entering on the left and exiting on the right,

fig.5
The Flow can be reversed by rotating the flow switch 180 degrees (i.e. ½ turn - see Fig. 6).
Fig.6
WARNING: The flow switch paddle can be damaged when reversing the flow direction if it is
lifted by more than 5mm from its housing and turned with force. If the flow switch
has been rotated it is important to ensure that it is finally locked in the correct
orientation perpendicular (at right angles) to the flow of water.
3.4 Connection
The unit is supplied with unions to allow connection to 2" or 63-mm rigid pipe. Reducers are also supplied
to allow connection to 50-mm or 1½" rigid pipe - see Fig. 7.
For pipework 63-mm or 2” in diameter.
Fig

For pipework 50-mm or 1½“ in diameter.
Fig. 7
All factory unions are made from ABS plastic, when gluing connections to ABS pipe an ABS cement must
be used or when using PVC pipe, a Transition cement must be used (See Fig. 7).
There is no need to use mastic or PTFE tape to connect unions to the H.R.UV-C SPA, use the O-rings
provided to put in the groove on the end of the Manifold Assembly.
NOTE: Be sure to apply the glue evenly and to all surfaces that will be in contact to reduce
the risk of leakage
3.6 Electrical connection
WARNINGS:
•This device must be installed by a qualified Electrician following the
instructions provided in this manual. The manufacturer will not be liable
for any issues caused by poor or improper installation.
•Any alterations made to the unit (unless stated) will affect the warranty.
This also applies if components are changed for non-standard
components acquired anywhere other than direct from the manufacturer.
•Incorrect installation may result in serious damage to property/persons.
•The H.R.UV-C SPA must be installed in accordance with the
country/regional requirements and regulations and an Electrical
Installation Certificate must be provided on completion of the installation.
•The power supply must be fitted with a 30mA RCD.
•Never look directly at an illuminated UV lamp.

4. OPERATING INSTRUCTIONS
4.1 Flow requirements
Minimum flow rate:
•1m3/hour (1,000 litres per hour)
Maximum flow rate:
•30W (Mini) = 12m3/hour (12,000 litres per hour)
•A higher flow rate will require the installation of a bypass to prevent damage to the unit.
This unit is a plug and play device so as long as the minimum flow rate is achieved the unit will work as
soon as the power is switched on.
4.2 Lamp life indicator
Under normal conditions the UV lamp(s) inside the unit has a usable life of 9,000 hours. The unit is fitted
with a ‘Lamp Life Indicator’ LED in order to remind you to change the lamp(s) after this set period of time.
At initial ‘Power On’ of the H.R.UV-C SPA the LED indicator will light in a Red colour for one second to
indicate that the time setting is 9,000 hours and immediately change colour to Green to indicate that the
timer has started.
When the timer reaches <500 hours the LED indicator will change colour from Green to Amber to indicate
that the UV lamp(s) is getting near to its end of life. At this point replacement lamp(s) should be ordered
from your distributor. When the timer reaches zero the LED indicator will change colour from Amber to
Red, to signal that the UV lamp(s) should be changed.
After changing the UV lamp(s) the timer is reset by pressing and holding the reset button until the LED
indicator goes ‘Off’ and then comes back ‘On’. When the reset button is released the LED indicator will
come back ‘On’ (Red colour for one second followed by Green colour), this indicates that the timer has
restarted and is reset to count down the subsequent 9,000 hours.
4.3 Water quality
The water quality MUST be within the following limits:
•PH: 6.8 –8.0
•Total Alkalinity (TA): 80 –140 ppm (parts per million)
•Chloride Content MAX: 150 mg/litre
•Free Chlorine: 2.0 mg/litre
•Total Bromine: Max 4.5 mg/litre
•Total Dissolved Solids (TDS)/Calcium hardness: 200 –1,000 ppm
WARNING: Failure to meet the water quality limits will void the warranty.
Upon completion of the installation, run the water-circulating pump to purge the system and heater of air
(i.e. remove any trapped air in the system).

5. MAINTENANCE
To avoid any water leaks and optimum performance annual maintenance of the UV steriliser is
essential. Failure to do so could result in damage to the product and significant drop in efficiency.
Annual maintenance includes:
•Changing of lamps(s) if necessary. Fig. 1
•Inspection and cleaning of quartz sleeve. Replace if any cracks are discovered. Fig. 2
•Replacing all O-rings. Fig. 3
•Replacing lamp connectors (white plastic insert inside the blue lamp shroud) if corroded, wet,
damaged or overheated. Fig. 4

5.2 Lamp replacement and quartz sleeve cleaning
Removing the lamp and quartz sleeve
Unscrew all the highlighted fasteners
Unclamping the clip from body
1. Pull the clip in shown direction to
unlock from body
2. Pull the second side after unlocking
the 1st side
Remove Lamp holder Clip from Hard cap
Unmount the Hard cap from Blue lamp
Holder
Carefully remove the blue lamp holder shroud and white plastic electrical end caps from
the lamp end

Gently slide the lamp out ensuring that no
pressure is applied to the glass quartz
sleeve.
Unscrew the blue quartz sleeve locking nut
anticlockwise. Both ends must be
unscrewed before the quartz sleeve can
be removed.
Slide the O-ring off the quartz sleeve
The quartz sleeve can now be removed.
Cleaning the quartz sleeve
Clean the sleeve and polish with a soft cloth or paper towel.
If you live in a hard water area there may be some limescale on the quartz sleeve. This can be easily
removed by soaking the sleeve in a proprietary kettle descaling solution (follow the manufacturer’s
instructions).
NOTE: Failure to remove the limescale will limit the effectiveness of the UV lamp(s).
Assembly process
•Firstly, slide the clean dry quartz glass sleeve into the unit.
•Locate the ’O’ rings carefully on the ends of the quartz sleeve.
•Make sure the threads are clean, wipe a little silicone grease onto the threads. As these threads
are only serviced periodically, this lubrication will help to prevent them binding together.
•Hand tighten the blue quartz sleeve locking nuts onto the unit. Be sure not to overtighten as this
can damage the quartz sleeve.
•Refit or replace the UV lamp(s) with a new one.
•Relocate the lamp connectors and blue lamp holder shrouds ensuring that you match the correctly
numbered lamp connector.
NOTE: To avoid bending the pins of the lamp during the reassembly pull the plastic fitting out of the shroud.
Connect it to the lamp and push the shroud back in to place

13
NOTE: Pinch the blue lamp holder shroud as you reassemble the unit to release any
trapped air. Failure to release the trapped air may cause the lamp holder to
disconnect from the lamp end. Turn on the water supply to check for leaks before
reconnecting the electric supply.
Important: The plastic body and blue compression fittings have been manufactured from polymers that
have been specifically stabilised to protect them from the effects of the UVC emitted from
the UV lamps. Despite this UV protection they will be eroded by a combination of the UVC
and water flow. As a matter of course they should be inspected whenever a lamp change
is carried out, to ensure they are not showing excessive wear and tear. Replacement parts
are available.
