DESCRIPTI N
WP10EX stainless steel Pressurized Washer System ith integral solenoid valve has been developed to be used ith
CCTV cameras in industrial, marine and highly corrosive environments. The asher system supplied pairs preferably ith
Tecnovideo camera housings or alternatively ith housings hich haven't asher facility. The fluid tank is a 10 litre
manually pressurized unit ith built in pressure gauge. Solenoid's control voltage to be connected to the solenoid's
terminal box through suitable po er cables. An AISI316L stainless steel compact cabinet protects the unit from the
environmental agents.

PRELIMINARY REMARKS
i
Prior to installation and operation, read carefully all instructions in this manual and in the solenoid valve installation
manual. Heed all arnings.
Unpack this equipment and handle it carefully. If the package appears to be damaged, notify the shipper immediately.
Use the original packaging to transport the unit. Disconnect po er supply before moving it. In case of returning the
equipment, the original packaging must be used.
Make sure that the
installation surface can support at least four times the eight of the unit in normal operating
conditions. In case of excessive external stress (e.g. vibration, strong inds or impact), the equipment may need additional
means of protection.
Proper stainless steel hard are should be carefully chosen to fasten the unit to the surfaces.
Use caution hen lifting and assembling the unit. It is recommended that non-
slip protective gloves be orn during
installation. The unit could bear sharp edges.
Keep the unit empty until the end of the installation.
The unit is intended to be used ith ater or ith ater solutions: denser mixtures could obstruct the nozzle. If the
solution used has residual, it must be filtered before use. Do not use inflammabl
e liquids, hydrogen peroxide (nor similar
substances that give off oxygen), corrosive substances, liquids containing ammonia, solvents and liquids containing
solvents, viscous or greasy liquids, liquids that form residues (dyes and greases).
The safety valve must not be bypassed or made inoperative.
Observe the legal requirements of your country for accident prevention and check the tank regularly.
Stainless steel reservoir: keep the O-
rings, the safety valve and the internal of the tank clean. When opening/closing the
reservoir, pay attention to the correct placement of the O-rings in their seatings.
Use appropriate tools for the purpose. The part
icular nature of the site here the device is to be installed may require
special tools for installation.
Tightening/loosing the scre s using automatic tools such as drill drivers may result in
damaged threads.

h
Before performing any
operation, turn off the po er. The installation of the unit can be performed only by qualified
personnel in accordance ith the regulations in force. Do not connect the unit to a supply circuit unless the installation is
completed.
Check carefully the su
pply voltage marked on the label. Incorrect Po er Supply Voltage may damage the unit. Do not
overload the terminal connection, as it may cause a fire or electrical shock hazard. Supply voltage tolerance= ±10%.
An all-pole mains
s itch ith an opening distance bet een the contacts at least 3 mm in each pole must be incorporated
in the electrical installation. The s itch must be equipped ith protection against the fault current to ards the ground
(differential) and the overcurren
t (magnetothermal, maximum 15A). It must be very quickly recognizable and readily
accessible. A suitable blo fuse must also be installed for protection.
For connection to the mains, use a multipolar cable having minimum 3x1,5 mm
2
(15 AWG). The main cabl
e must be at
least protected by an ordinary PVC sheath.
Fasten all the cables inside the housing ith cables ties or other fixing means to avoid the electrical contact ith
surrounding parts in case that terminal blocks scre off.
Electrical
connections (such as plugs and cords) must be protected from potential hazardous environmental factors (e.g.
foot traffic, hitting objects).
Ensure that the unit case is properly earthed, connecting all the earth ground studs. Earth cable should be
about 10mm
longer than the other cables on the connector, in such ay that it on't be accidentally disconnected if the cable is
stretched or pulled.
When leaving the unit unused for long periods, disconnect supply cables.
b
Do not connect the unit to a supply circuit unless the installation is completed.
It is recommended that all the connections are performed and tested on a safe area laboratory before installing on field.
If antifreeze and/or detergent additives have to be used, they must have a kindling point 50° C higher than the maximum
permitted operating temperature. Do not use liquid that could cause ignition of the atmosphere.
The electric connections bet een the solenoid valve and the Pan&Tilt unit must be housed in an explosion-
proof junction
box, suitable to the explosive atmosphere in hich the units ill be used.

INSTALLING THE UNIT
pening the washer system
Loosen the t o M6 scre s to remove the cover and to access the
internal parts.
Do not remove the scre s.
Scre s
Passing the cables
There are 5 fairleads placed 2 at the bottom and 3 on the side of
the frame. Push the cable and the ater hose to enter the cabinet.
No cable gland is required for cable entry into the cabinet.
Fairlead
Electrical connections
Perform the electrical connections either from a telemetry or from
a proper s itching system to the solenoid valve.
The connection must be performed via the solenoid valve cable
gland (included).
Check the valve label for the correct supply voltage.
When supply voltage is provided, the solenoid valve ill open
letting the ater output.
Be sure to properly connect the ground to every marked point.

USAGE
Filling the tank
Pull the red safety valve to assure that the pump is not under
pressure.
Rotate counterclock ise the pumping element to unscre it and
remove it. Fill the tank ith maximum 10 litres of liquid.
The quantity of ashing cycles ith a single refill is about 200-500
(results may vary depending on camera height, pressure, ater
level).
Fix the pumping element, checking that the O-ring and its seating
are clean. Pressurize only using the pumping element.
Do not force the safety valve. Do not unscrew the hand pump if the
tank is under pressure. The unit is intended to be used with water or
with water solutions: denser mi tures could obstruct the nozzle. If the
solution used has residual, it must be filtered before use. Do not use
inflammable liquids, hydrogen pero ide (nor similar substances that
give off o ygen), corrosive substances, liquids containing ammonia,
solvents and liquids containing solvents, viscous or greasy liquids,
liquids that form residues (dyes and greases).

Safety valve
Usage
Unlock the pump handle by pushing it do n and rotating it. After
a fe moments pull the safety valve to check that it's not blocked
and that air goes out. Pump until the desired pressure is reached.
Ma imum pressure is 4 bar.
Lock the handle. When the camera ater jet eakens, it is needed
to restore the internal pressure. Eventually close the cabinet.
Maintenance and filter replacement
This equipment has been designed to fit in harsh environments requiring little or no maintenance. Suggested
inspection interval is 6 months, but extremely harsh environments may require more frequent inspection and
maintenance checks. On each inspection check the proper orking of the red safety valve. Also, on each inspection
check O-ring seals. Replace them if necessary. Check tank, hand pump and pressure gauge integrity. If any damage is
noticed, please contact Tecnovideo for spare parts.
Check cables, electrical connections and mounting hard are for integrity and tightness. Replace or tighten any
damaged/loose part.
Check the filter bet een the tank and the solenoid valve.
It is suggested to replace the filter on a yearly basis (one spare filter
is provided ith MKWP10EX maintenance kit). Replacement
interval may be shorter, depending on the impurities level in the
ater.
To replace the filter, pull red safety valve on the top of the tank to
assure that the pump is not under pressure. Disconnect the filter
from the hoses through the quick connect fittings. Connect the
ne clean filter.
Do not disconnect the filter if the tank is under pressure.
When connecting the new filter, pay attention to the arrows marked
on the filter body, these indicates the water flow. Connect the two
hoses to the filter according to the arrows/water flow direction.
