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 and 5).
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,

7
The Flow can be reversed by rotating the flow switch 180 degrees (i.e. ½ turn - see 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.

8
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 a 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.

Chemical Dosing Set-Up

12
The controller is pre-programmed to dose two chemical types:
A. Hydrogen Peroxide / Active Oxygen / H₂O₂
B. Liquid Chlorine
Part 1
To set the type of chemical: use the / buttons until “DOSE CHEMICAL” is displayed, press the
O.K. button and then use the / buttons to choose:
A. ‘H2O2’ or
B. ‘CHLORINE’
Press the O.K. button to select
A. Dosing Hydrogen Peroxide (H₂O₂)
After selecting ‘H2O2’ in Part 1 the display will now show ‘H2O2 DOSE’ the / buttons select the
correct dosage volume in ml (millilitres) –Refer to Table A for suggested H₂O₂dosing figures.
Once the correct dosage volume is displayed press the O.K button to confirm, the display will then show
‘H2O2 START’
You now need to enter the time that you would like the dosing to take place –NOTE: the time must be
entered in the 24-Hour format and the dosing will take place at this time every day (24-Hours).
NOTE
•The time selected must be at a time when the main filtration pump will be running.
•Once the desired time has been selected press the ‘O.K.’ button and the display will then
show ‘SAVED’.
•If the dosing volume is set to 0.0 (ml) the peristaltic pump will remain off.
•In the event of power loss: the programmed settings (dosing volume and dosing time) will
remain stored. If the power to the controller is switched off for longer than 3-Hours the
current time will need to be re-programmed, this is indicated to the operator by the clock
flashing.
Set Dosage Requirements
•Please note: Dosage amounts are set in ml/day (millilitres per day).
•Use the below reference table as a guide.
•To calculate your pool volume, see page 20 at the rear of this manual.

Table A
NOTE
•The above table is based on dosing Hydrogen Peroxide (H ₂ O ₂ ) with a 32% concentration
and a water temperature of 28⁰C.

13
For a concentration of 12% the above dosing amount should be multiplied by 3 (i.e. the dose for a 50m³
pool would need to be increased to 960ml/day when the H₂O₂strength is 12%).
For any other concentration strengths, the dose amount should be adjusted pro-rata as required. The
digital controller will automatically sense the temperature of your water and adjust the required dose
accordingly.
B. Dosing Liquid Chlorine
Refer to table B for suggested Liquid Chlorine dosing figures.
•TRICKLE DOSING: When dosing liquid chlorine the required daily dosage amount will be
split into multiple intervals within the filtration hours (for example, 420ml will be split into 20
smaller doses. Each dose will be injected for 32 seconds, and they will be equally spaced
throughout a 6-hour period).
•If a power cut occurs during Trickle Dosing the unit will continue to dose the outstanding
volume once the power has been restored. Please note - the volume that should have
been dosed during the time of the power loss will be skipped.
•The controller does not monitor the free chlorine level. The pool free chlorine levels must
be regularly checked, and the dosage volume adjusted if required.
.
After selecting ‘CHLORINE’ in Part 1 the display will show ‘CL DOSE’ using the / buttons select
the correct dosage volume in ml (millilitres). Once the correct dosage volume is displayed press the O.K
button to confirm, the display will then show ‘CL START’
You now need to enter the time that you would like the CL dosing to take place. Once the correct time is
selected press the ‘O.K.’ button.
NOTE:
•The time must be entered in the 24-Hour format and the dosing will take place at this time
every day (24-Hours).
•The time selected must be at a time when the main filtration pump will be running.
•If the dosing volume for CL period is set to 0.0 (ml) the peristaltic pump will remain off.

Shock Dose
The shock dose feature enables the operator to shock dose the pool immediately with a chosen volume
of the dispensing chemical. This may be necessary following heavy use of the pool or a change of water
conditions.
To activate the shock dose feature, use the / buttons to scroll until ‘SHOCK DOES’ is displayed,
press the ‘O.K’ button.
Using the / buttons select the volume (ml/millilitres) that you would like to shock dose the pool
with. When the correct value is shown, press the ’O.K’ button to confirm. The display will show ‘SAVED’
and the shock dose will begin immediately.
NOTE: The shock dose will only begin if the main filtration pump is operational.
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 bulb cap) if corroded, wet,
damaged or overheated. Fig. 4.
5.1 Essential parts to carry out annual maintenance including our reference codes
WARNING: Before performing anymaintenance isolate from the main power supply, turn
off circulation pump and drain the unit.

5.2 Lamp replacement and quartz sleeve cleaning
Removing the lamp and quartz sleeve

15
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

16
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.

17
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 beenmanufactured 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.
5.3 Intelligent dosing pump routine maintenance
We recommend that the dosing tube is changed every 6-12 months in order to prevent any wear and tear
and keep performance to an optimum. The following steps will guide you how to replace the dosing tube:
STEP ONE
Unscrew the two screws securing the plastic cover
and remove. Rotate the grey connections caps to
release the tubing.
STEP TWO
Remove the connection point on the left-hand side,
and then carefullymanually rotate thecam to allow
remove of the dosing tube.

18
STEP THREE
Cut the two black securing ties at either end of the
tube. This will then release the tube, which can be
discarded.
STEP FOUR
Take the replacement tube and re-attach
connection points. Loop securing ties in place in
order to seal to the connection points. Once
securely in place cut the excess tie and dispose of.
STEP FIVE
Place dosing tube into position on the left-hand
side. Carefully rotate the cam clockwise, whilst
feeding the pipe back into place.
STEP SIX
Replace the suction and output tubes on to the
connection caps and rotate to secure tubing back
into place. Replace clear cover and screw into
position.

8. CALCULATING POOL VOLUMES
The following pages will show you how to calculate the volume of the pool.
NOTE: For pools with different depths:
D1 + D2 = Average Depth
2
If your pool has a sloping bottom, then take the deepest measurement (D2) and the shallowest (D1). If
there are different levels, then you need to do several calculations of area for each depth and add them
up at the end.

20
Rectangle and Square Pools
Volume = Length (L) x Width (W) x Depth (D) or Average Depth
Circular
Volume = π (3.142) x Radius2 x Depth (D) OR Average Depth
Radius = Diameter divided by 2
Ellipses
Volume = π (3.142) x A x B x Depth (D) OR Average Depth
Irregular Shapes
For irregular shapes, calculating the area is less accurate. You will need to draw the pool accurately to
scale on graph paper using one square on the graph paper to represent a metre (or foot) square of pool.
When you have completed, count the squares.
For partial squares, count anything over half as one and ignore any under a half. When you have the area
(A) multiply by depth (D) for the Volume in cubic metres. If you have several depths, break up your area
calculation for each depth.
