4. Refitting the Cover
· Ensure the internal flow valve is in the fully closed position, turned
clockwise as far as it will go and pointing straight up (see diagram 2).
· When the cover is replaced ensure that the temperature control dial on the
front cover indicates that the valve is closed. This ensures the external
indication of the valve state (open/closed) as seen by the user corresponds
with the true physical state of the valve (open/closed).
· Gently engage the temperature control dial on to the valve spindle (see
diagram 2) as you replace the cover. Check that the valve will now operate
fully in both directions.
· The manual unit HW30M also features a linking rod that connects the on/off
switch with the power dial. The linking rod has a “D” cross section that
ensures it will only connect with the rod in the correct orientation.
· Replace the two pairs of screws on the top and bottom of the appliance.

5. Operation
Do not use the appliance in an ambient temperature exceeding 30°C.
Do not switch on if there is a possibility that the water in the appliance is
frozen.
On first use the commissioning sequence must be followed to prevent dry
operation of the element.
Commissioning · Turn on the water supply to the appliance.
· Turn the temperature control dial on the front of the appliance fully
clockwise to the commissioning setting (°C) (see diagrams 3 and 4). This
disables the heating element.
· Turn on the electrical supply and activate the water flow:
HW30A – place your hand close to the circular infrared window HW30M – turn the
power control dial clockwise to the ON position (ON = 1, OFF = 0)
· Allow water to flow through the appliance until a smooth spray is achieved
from the spout for several seconds.
· This completes the commissioning cycle. It must be repeated if the tank is
ever drained.

Normal Operation HW30M – Manual Model · Turn on power to the appliance using
the power dial (see diagram 2). Adjust the
temperature control dial until the desired temperature is achieved. When hand
washing is complete turn off using the power dial. HW30A – Automatic Model ·
Turn on by placing the hand near the red infrared sensor. Adjust the
temperature control dial until the desired temperature is achieved. The
automatic appliance will deliver a timed flow of water for approx. 30 seconds
or until the appliance is switched off by again placing the hand near the
infrared sensor. Water Temperatures · This appliance is an instantaneous water
heater consuming a fixed 2.84 kW of power. This power will raise the
temperature of the incoming water by an amount that reflects the flow rate. A
low water flow results in a higher temperature uplift and a high flow results
in a lower uplift. · E.g. the heater could deliver 42°C water in the summer
(with an incoming water supply temperature of 17°C). The same product with the
same flow rate would only be able to deliver 38°C in cooler months (due to a
lower incoming water temperature of 13°C). Both examples based on 1.6 l/m flow
rate.

6. Cleaning and Maintenance
The appliance should only be installed and maintained by a competent person in
accordance with any local electrical and plumbing regulations. Do not use
abrasive chemicals or cloths to clean this appliance. Isolate the appliance
from the electrical and plumbing supply before performing any maintenance
task. Ensure the appliance has cooled down before performing any maintenance
task. The appliance should be drained if it will be switched off or unattended
for any length of time, particularly during the colder months of the year
where the possibility of freezing temperatures exists. Ensure any future
maintenance or modifications to the plumbing system also complies with the
guidelines in these instructions. Keep records of maintenance and ensure any
future occupier of the building is fully aware of the content of these
instructions.
· Visually inspect the appliance and its immediate surroundings regularly for
any signs of water escape that might indicate the product may be nearing the
end of its natural life.
Descaling the Spray Head · The spray head will require descaling periodically.
Failure to do so could result in an
internal pressure build-up. · Unscrew the central screw in the sprayhead and
remove any solid debris under a
running tap. To remove stubborn scale it may be necessary to use a suitable
hard brush or to soak the parts in a descaling solution. Cleaning · Wipe
surfaces with a clean, damp (not wet) cloth. Do not use abrasive compounds.

7. Additional Information
Safety Features · This appliance is fitted with two levels of thermal
protection, the first is an auto
reset cutout that will operate at 60°C. The second is a manual reset cutout
that operates at 90°C. Automatic Thermal Cutout · In the event the auto reset
cutout operates the element will not heat until the water temperature cools
below approx. 30°C. See section 8. Troubleshooting for more information.
Manual Reset Thermal Cutout
Do not attempt to reset the manual cutout unless the power has been isolated
from the appliance. · In the event the manual reset thermal cutout operates
the element will not heat and will not reset automatically. To perform a
manual reset it is necessary to remove the front cover in order to access the
reset button. · Once the cover is removed the manual reset thermal cutout can
be reset by pushing the reset button (see diagram 5). · The cause should be
established before continuing use if the manual reset thermal cutout operates.
A low flow or obstruction in the spray head is the most likely cause and this
problem should be rectified prior to restarting use of the appliance.
Diagram 5 12
This appliance incorporates a safety relief valve; do not attempt to modify
this in any way. Pressure Relief Valve · In the event of an over pressure
event a small silicone ball will be expelled from the appliance which will
allow the built up pressure to be released (see diagram 6). · If the valve
does operate the reason for the discharge should be established and rectified
before replacing the relief valve ball (a common cause can be a scaled up
spout head). The replacement process is as follows: · Isolate the appliance
from the power and water supply. · Spare relief valve balls and the required
tool are available from Hyco as spare parts. · Using the appropriate tool,
push the ball into the valve at the base of the tank (behind the spout) and
push into the valve as far the tool will allow. · Reconnect the appliance to
the power and water supply in turn. · Commission the appliance (see section 5.
Operation) and inspect to ensure the issue is resolved and no water is
discharged from the relief valve.
