Kokido xtrovac 70 User manual

xtrovac 70 cleans the bottom of your pool
automatically and works with all major brands of
soft wall pools.
The cleaner is a unique, automatic suction side
cleaner that is compatible with pumps as low as
32W (3.03m³/h) or 800gal/h.
The cleaner is equipped with a pressure regulator
that can be adjusted to work with pump with a
water flow rate up to 2000gal/h (7.5m³/h).
The cleaner has a filter cage that prevents the
clogging of your filtration system and uses the
diaphragm technology for a silent automatic
cleaning of your pool.
WARNING!
- THIS IS NOT A TOY!
- Do not let children use or play with the cleaner.
- Do not allow swimming in the pool when
cleaner is in operation.
- TURN OFF THE PUMP prior to connecting
the cleaner to the pool.
- If there are stones, roots or metal corrosion in
contact with the underside of the liner, discard
them prior to installing the cleaner. If necessary,
seek assistance from a qualified professional.
- If the liner is brittle, damaged or wrinkled, contact a qualified professional to perform the
necessary repairs or perform a liner replacement prior to installing the cleaner.
- Make sure the cleaner is not in the pool during chemical sanitization.
- TURN OFF THE PUMP prior to servicing the cleaner or performing maintenance of any kind.
Initial Set-up
- Close the main drain at the bottom of the pool.
- Make sure the pump and pool filters are clean.
- Make sure the hoses are straight. Otherwise, place them under sunlight for a few hours to
straighten them.
- If your pool is filled with leaves or large debris at the bottom, they must be removed using a
leaf rake (not included) prior to operating the cleaner. This will prevent the filter cage from filling
up too quickly and allow the smaller particles to be collected instead.
- For above ground pools with two pool water outlets – refer to the cleaner’s instruction manual
and connect it to one of the water outlets and block the second one according to the pool’s
instruction manual. For example, use a pool plug to block the outlet or set the control valve
(e.g. plunger valve) to the closed position (if available). Otherwise, it will decrease the water
flow inside the cleaner and cleaner performance may be impacted as a result (i.e. capturing
less debris, not moving/moving slowly, poor pool coverage, etc.).
WARNING! TURN OFF THE PUMP BEFORE YOU CLOSE THE WATER OUTLET.
PRESSURE REGULATOR ADJUSTMENT
Excessive water flow from the pump/ filtration may result in the cleaner being stuck to the pool
bottom. On the contrary, insufficient water flow may inhibit the cleaner’s movement.
The cleaner includes a pressure regulator at the top that can be adjusted for pumps with a flow
rate up to 2000 gal/h (7.5m³/h). The default setting of this regulator is designed for use with
pumps with a flow rate of 1500 gal/h (5.6m³/h) or less. The pressure regulator is made up of parts
R1 thru R4 shown. (Fig.1)
WARNING! TURN OFF THE PUMP BEFORE ADJUSTING THE PRESSURE REGULATOR.
HOSE CONNECTOR ASSEMBLY
WARNING! TURN OFF THE FILTRATION SYSTEM PRIOR TO ASSEMBLING ANY HOSE CONNECTORS.
4 connectors (F1/F2/F3/F4) and Green short hose (A) enable the cleaner to fit most
brands of above ground pools on the market.
Select the right hose connector and refer to the following diagrams on how to establish a proper
connection to the strainer on the water outlet of your pool.

HOSE SECTIONS ASSEMBLY
The total length of assembled
hoses should be half to one hose
section length longer than the
length measured from the pool
strainer (water outlet) to the
farthest point in the pool. (Fig.2)
Refer to the diagram sequence below and connect the hose
sections accordingly:
• Strainer connector (F)
• Green short hose (A)
• Swivel (B)
• Male-female superflex hose (D)
• Male-female long hose (E)
• Superflex hose (D)
• Female-female short hose (C)
The quantity of male-female long hose (E) will depend on the length required for your pool and
must be connected between the 2 male-female superflex hose (D) below. Make sure to connect
the female-female short hose (C) to the cuff of the cleaner.
Fig.2
IMPORTANT NOTE:
- The swivel (B) allows the cleaner to turn smoothly. Do not alter its position or remove it.
For 610cm (20ft) round / rectangular pools, connect all 9 male-female long hose (E) and all
2 superflex short hoses (D) included.
For 457cm (15ft) & 485cm (16ft) round / rectangular pools, connect 7 male-female long hose (E)
and 2 superflex short hoses (D) included.
For pools in size smaller than 457cm (15ft), reduce the number of male-female long hose (E)
until total length of hose assembly is equivalent to the length from skimmer/dedicated suction line
to the farthest point in the pool plus a length equal to hose (E).
Immerse the hoses into the water one by one in the correct sequence to expel the air. Be sure to
complete the hose connection underwater. Alternately, you can connect all hoses together and place
either opening end towards the pool water inlet to let water flow expel the entrapped air.
Trapped air in your cleaning system may prevent the pump from operating smoothly. If this
happens, switch off your pump, open the release valve (if applicable) on your filter and let air
escape until only water comes out from the release valve, then close the valve.
Refer to your filtration manual on how to release the air.

Align the screw holes on R4 and R1 and tighten the screws accordingly once the ideal pressure
release setting is selected.
Remark: Pumps of the same horse power rating from different brands may vary in performance.
You may need to adjust the regulator for additional pressure release if the cleaner is stuck to the
pool floor and does not move because of excessive suction.
CAUTION! Do not expose the regulator to air while it is in operation, otherwise air might be
trapped and affect the cleaner / pool pump / filtration operation as a result.
Default setting (no opening
on grid) is designed to use
withpumps with a flow rate of
1500 gal/h (5.6m³/h) or less.
To alter the setting,
unscrew both screws
from R4.
To achieve minimum pressure
release, rotate R4 clockwiseuntil
a small opening is exposed on R1
(ensure the screw holes on R4
and R1 are aligned).
To achieve medium pressure release,
rotate R4 clockwise further, a bigger
opening (2 holes) on R1 is then exposed
(ensure the screw holes on R4 and R1
are aligned).
To achieve maximum pressure release, rotate R4
clockwise further and all holes should be unblocked
on R1 (ensure the screw holes on R4 and R1 are
aligned). This setting is recommended for pumps
with a flow rate up to 2000 gal/h (7.5m³/h).

HOSE WEIGHT APPLICATION
WARNING! DO NOT ATTACH THE HOSE WEIGHT ONTO THE SUPERFLEX SHORT HOSE (D), AS IT MIGHT DAMAGE THE HOSE.
Ideally, the bottom surface of the cleaner should rest flat on the pool bottom. Initially, attach the hose
weight onto the first male-female long hose (E) from the hose assembly, close to the next male-female
long hose (E).
NOTE: Do not try to slide the hose weight along the hose as it could cause damage to itself or the hose.
Pull the hose weight upward to detach it from the hose

HOW TO OPERATE THE CLEANER
CAUTION! REMOVE THE LADDER FROM THE POOL BEFORE OPERATION
Once your cleaner is connected to the pool water outlet, turn on the pump. Cleaner starts cleaning
the bottom of you pool. It will operate automatically until the filter cage is full. Make sure the filter
cage is in place during cleaner operation. Otherwise, debris may go through the cleaner to clog
your pump.
Clean the filter cage and diaphragm regularly to ensure maximum suction.
CLEANING FILTER CAGE/DISPHRAGM
Switch off the filtration system, press on the clip to unlock and slide the bottom plate off the cleaner.
Remove the filter cage and rinse it
with clean water. Replace the filter
cage if you detect any damage.
Grip onto the diaphragm and pull it out carefully.
Clear the insides of diaphragm.
NOTE: Never put sharp object inside diaphragm as it may damage it.
After cleaning, reverse the steps to assemble the unit. Make sure the retaining ring is in place.
Reverse the steps to reinstall the diaphragm and filter cage into the cleaner.
Make sure the diaphragm is completely inserted.

TROUBLE SHOOTING
WARNING! TURN OFF THE PUMP BEFORE YOU ATTEMPT TO RESOLVE TROUBLESHOOTING OF ANY KIND.
Problem
Cleaner

slowly
The
cleaner’s
path does
not cover
the entire
pool
Solution
• Check to see if there are any air bubbles coming from the pool return line that appear
in the pump. Refer to the pump’s manual on how to remove the air.
• Check to see if there are any air bubbles coming from the hose connections and
fittings. Tighten the connections and fittings and inspect them again. Make sure all
assemblies are carried out properly.
• Check if swivel is placed on wrong position. Position it according to the instruction.
Swivel should be positioned under water, otherwise air may goes into the hose and
then the pump through the swivel.
• Check to see if the pump power is adequate. Verify with the information on the pump
or with your dealer that the power of your pump is not less than 32W and that the
minimum system flow rate is 3.03m³/h or 800gal/h.
• Check and see if there is insufficient water flowing through the cleaner.
- Check and see if your filtration system is reducing the water flow significantly and
consequently the cleaner’s suction. If your filtrations system consists of a multiport
valve, turn the valve to "Circulation" position to bypass the filter. Otherwise, refer to
your filtration manual on how to directly steer the water return to the pool. Ensure the
filter cage is in placed inside the cleaner.
- A solar heater may reduce the flow significantly and affect cleaner suction as a result.
In such scenario, use a bypass valve and adjust the bypass valve for the water to flow
directly to the pool, skipping the solar panel.
• Check to see if the filer cage is full. Clean it if necessary.
• Check to see if the diaphragm is clogged with debris. Release the diaphragm and
clean out the debris if so.
• Check to see if the pressure regulator is releasing excessive water flow.
Adjust it according to instructions.
• Check to see if the cleaner sticks to the pool bottom. If a pump of flow rate higher than
1500 gal/h (5.6m³/h), please refer to “Pressure Regulator Adjustment” to reduce
water pressure and suction.
• If there are two water outlets in your pool, make sure that the water outlet connected
to the cleaner is opened and that the other is closed.
• Check if the bottom plate is secured properly at the bottom of the cleaner.
• Check if the vacuum plate is securely attached to the strainer of wall skimmer.
• Make sure the total length of hose is sufficient according to the instructions.
• Make sure the hoses are not kinked or coiled. Lay the hoses under sunlight to
straighten the hoses if necessary.
• The superflex short hose (D) influences the movement path of the cleaner, allowing a
better coverage of the pool. Re-position the superflex short hose (D), which is next to
the white short hose (C). However, do not alter the position of the superflex short
hose (D) that is attached to the swivel (B) as it will change the cleaning pattern of the
cleaner. You may also rotate or twist some hose sections because hoses will bend
over time, creating a routing pattern in the process.
• If there are two water outlets in your pool, make sure that the water outlet connected
to the cleaner is opened and that the other is closed.
• Check if the bottom plate is secured properly at the bottom of the cleaner.
• Check if the vacuum plate is securely attached to the strainer of wall skimmer.
MAINTENANCE & WINTERIZATION
• Do not coil the hoses.
• Use clean water to rinse the cleaner, hoses, and other accessories after every use.
• Periodically inspect the cleaner parts and accessories. Replace damaged parts before next use.
• For winterization, drain the water from the cleaner and accessories. Disconnect hose sections
and store them straight. Store the cleaner and all accessories in a place away from sunlight
and chemicals.
NOTE: Make sure that the bottom plate is secured before the next operation.
If the cleaner leans forward, detach the hose weight and move along the male-female long hose (E)
towards the cleaner. If the cleaner leans backward, detach the hose weight and move to the next
male-female long hose (E).
Once your cleaner is connected to the pool, turn on your pump. The cleaner will then begin
cleaning the bottom of your pool. Operation will continue until the filter cage is full of debris.
NOTE: Clean the filter cage prior to use every time.
