TYPE C350 GENERAL SYSTEM DESCRIPTION
This C350 Clear View Screen is suitable for mounting on all vessels provided the window
dimensions are above the minimum requirement of 510mm wide and 533mm high, and the
windscreen between 10 and 32 mm thick.
The Wynn C350 is designed to meet or to exceed ISO 3904:1990(E) (BS7470:1991) standards.
The centrifugal force created by the spinning disc of the Clear View Screen throws off all rain,
spray, snow or ice giving instant clear vision. In accordance with ISO 3904, the Wynn C350 is
defined as: ISO 3904-C-350-AL-vf, where vf is voltage and frequency identification number.
Toughened glass is used both for the fixed and the rotating screens. The rotating screen is
balanced such that little vibration or noise is generated. This also allows high rotation speeds to be
used making it particularly effective in heavy weather / sea spray conditions.
The motors are fan cooled, constant speed Induction motors. 4-pole motors are used on 60 Hz, 2-
pole on 50 Hz.
Optional metal sheathed, ceramic filled heaters are used of the same voltage as the screen motor.
For rapid ice and misting clearance, power consumption is approximately 250W. In addition, air
from the motor fan cooling is directed onto the inner screen to aid heating.
A connection box is incorporated within the C350 in order that the CVS controller may be
connected to the C350 Motor and Heater. The Clear View Screen must be mounted with the
control box at the bottom.
Note: This product is not recommended for sloping glass beyond 10° forward or backwards, or for
windows likely to be struck by waves. Seawater is likely to be retained within the space between
the two screens.

TYPE C350 INSTALLATION
These instructions assume that the required mounting hole is already available in the windscreen.
It should be checked for compliance with the 390 - 392mm diameter limits, and the glass thickness
should be checked against the Certificate of Conformity, supplied with the product.
In the case of the need to remove or replace the rotating screen, a tool is supplied with the product.
1. The wiper must be installed with the control box at the bottom of the wiper.
2. Clean the area on both sides around the hole in the window.
3. Open the Control Box and disconnect the heater wires from the terminals. HL1, HL2 and E.
4. Remove the 12 cap screws from the clamp ring and carefully remove the clamping ring
pulling the heater power & earth wires through the cable hole out of the control box.
5. Insert the Clear View Screen, complete with the Control Box attached, through the hole from
the outside of the windscreen.
6. Refit the Clamp Ring carefully feeding the 3 wires from the heater through the hole in the
clamp ring.
CAUTION: Insert the cap screws and tighten carefully until an even pressure on the
rubber gaskets is achieved without distorting them and causing them to extrude outside of
the outer rim or clamp ring. Do NOT over- tighten.
7. Carefully feed the heater power and earth wires through the slot in the back of the Control
Box and connect the wires as per sleeve marking to terminals marked HL1, HL2 and E.
8. The motor wires are supplied connected to ensure the correct direction of running. The
correct direction of rotation is clockwise viewed from inside the window.
9. Wire motor and heater to CVS Control Unit.
10. Switch both the screen and the heater, if fitted, OFF.
11. Check that the rotating screen is free to rotate freely and without any sound - make sure no
packing materials are trapped in the labyrinth seals. See Fault Finding Guide if there are
difficulties.
WARNING: ISOLATE the supply and then connect the supply cabling to the incoming
terminals as shown on the wiring diagram.
12. Switch on the supply.
13. Switch on the screen switch and check that the rotating screen is running in the correct
direction as stated above. See Fault Finding guide if there are difficulties.
14. Switch on the heater (if fitted). The outer rims of the wiper should become warm within 5
minutes.
15. Switch off the screen and heater. Clean the glass of the screens and any other dirty areas.

Water Seal Test
1. Spray water at right angles to the screen and directly at the centre of the screen whilst
rotating.
2. In the case of water ingress, stop the rotating screen and allow water to drain out.
3. Turn on the heater and wait a few minutes for the screen to de-fog.

TYPE C350 OPERATING INSTRUCTIONS
CAUTION: If operating in freezing weather always switch on the heater first allowing 10
minutes for any ice attached to the rotating screen or sealing area to melt before
switching on the C350.
If the ice has not cleared sufficiently the screen WILL NOT start up. If the ice has not started to
melt after 10 minutes the heater is not functioning.
Note: In the stalled condition the motor will heat up until a thermal cut-out will disconnect power to
the motor to prevent damage at an internal temperature of 100 C. The cut-out will reset when the
motor temperature has fallen around 10 C.
1. If vision through the C350 is obscured by condensation, switch on the heater and screen
together. It may take up to 20 minutes for the screen to clear completely.
2. Switch on the C350. It will take up to two minutes to accelerate to normal operating speed.
3. Should the wiper fail to operate when first switched on - follow the fault finding procedure
below.
4. Switch off the heater when not needed: Leaving the heater on continuously in high
temperature conditions will reduce its life.
Note: The CVS consists of two circular glass screens, one of which rotates. When the
temperature of the outside and inside of the glass is different, the fixed glass screen can collect
moisture according to the weather conditions.
