To replace the fuse remove the complete white plastic tubular control pod by undoing the two bolts holding it
in place on the main unit and removing the lamp lead assemblies from each lamp.Work with the mains cable
positioned to your right hand side.With the control pod free of the main unit loosen the four black plastic lamp
lead watertight grommets situated at the left hand end of the control pod. On this end only also remove the
screw situated in the centre of the end section. Do not remove the screw or loosen the mains cable at
the right hand end.With the left hand end section now free, hold the right hand end assembly and gently pull
out the right hand end assembly (approximately 75mm) until you expose the fuse holder assembly.The fuse
holder assembly is easily identified as it carries a spare fuse that is clearly visible.
Once the fuse has been replaced, gently slide the assembly back into the plastic tube and reassemble the left
hand end section ensuring that the screw is tightened correctly and all four watertight grommets are sufficiently
tightened to prevent any moisture entering the control pod.
Bolt the complete control pod back into the main unit and reconnect the lamp end assemblies ensuring that you
match the correct numbered lamp holders.
ROUTINE MAINTENANCE
Under normal conditions, the UV lamps inside the Pro Pool unit have a useable life of 1 year or 8000 hours. Where
the pool is heavily used all year round the lamps should be changed every 6 months or 4000 hours.
As already mentioned, it is essential that the unit is protected from frost during the Winter months, or disconnected
from water and electricity supplies and stored indoors during the Winter. During the Spring/Summer season, the
quartz sleeves, which separate the UV lamps from the water passing through the unit, will need to be cleaned two or
three times.This is essential, as dirt or calcification building up on the quartz sleeves will inhibit the penetration of the
ultraviolet light into the water.
LAMP REPLACEMENT & QUARTZ CLEANING
Isolate from electrical and water supplies before carrying out any maintenance.
Lampholder Restraint
A plastic lampholder restraint is fitted at either end of each lamp chamber to prevent the lamp holders being accidentally
removed while the unit is connected to the mains. Each restraint is held in place with a self-tapping screw. To carry out
any routine maintenance these restraints must be removed but it is essential to replace them once the maintenance
work has been done. In time it may be necessary to replace the fixing screw (no.8) with a slightly larger screw.
To remove the lamp, carefully remove the blue lampholder shroud, then pull the white plastic electrical end caps
from the lamp end. Gently slide the lamp out ensuring that no pressure is applied to the quartz sleeve. Next,
unscrew the two blue compression fittings located at either end of the white plastic body and slide off the 'O'
rings.Then slide out 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). Failure to remove the
limescale will limit the effectiveness of the UV lamp.
ASSEMBLY PROCESS
Slide the clean, dry quartz sleeve into the unit. Ensure that you locate the 'O' rings carefully on the ends of the
quartz. Failure to do so will result in leaks when the water is turned on.
If you are carrying out the annual lamp change, use new 'O' rings.When you re-assemble the unit, ensure that the female
threads on the compression fittings and the male threads on the main body are clean. Wipe a little silicon grease or vaseline
(NOT silicon sealant) onto these threads. As these threads are only serviced periodically, this lubrication will help to prevent
them binding together. Then replace and firmly hand tighten the compression fittings. Replace the lamp or fit a new one.
Relocate the lampholders and blue lampholder shrouds ensuring that you match the correct numbered lampholders.
NOTE: Pinch the blue lampholder shroud as you reassemble the unit to release any trapped air. Failure to release
the trapped air may cause the lampholder to disconnect from the lamp end.
Reconnect and 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 lamp. 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 from Tropical Marine Centre and its agents.
