Lifting
Evoplate - Installation, Operating & Maintenance Instructions
Lifting lugs are fitted on the top of the vessel. These should be used
when lifting the vessel into position. Ensure the vessel remains in a
vertical position (for vertical vessels) and horizontal position (for
horizontal vessels) throughout.
Foundations
Level foundations should be prepared for the buffer vessel. Uneven
foundations can cause airlocks within the vessel and the vessel could
be unstable when maintenance work is carried out.
The vessel should be attached to the foundations using bolts through
the bolt holes on the vessel foot pads.
Flanges and Bosses
PTFE should be used when fitting
screwed connections to the
vessel bosses.
When fitting flange connections,
ensure mating flanges are square
and that the weight of the
pipework is supported by
external supports and not the
vessel connections.
Expansion of pipes should be
considered for the application
and measures put in place if
necessary.
Filling and Draining
Tighten any bolts on the vessel prior to filling as these may have
become loose during transit. Ensure bolts are tightened diametrically
and to the correct Torque. (if in doubt contact Ormandy Limited
technical department).
When filling the vessel ensure the vent connection on the top dished
end is open. When the vessel is full the vent boss should be plugged.
When draining the vessel ensure the vessel is released of pressure
slowly and that the vent is then open before draining commences.
Relief Valve
Ensure that the relief valve is
fitted with a discharge pipe (on
the valve outlet). The pipe should
open to atmospheric pressure
and run to a low level suitable
drainage area.
Inspection
Internal inspection of the vessel should take place after the first 3
months. The inspection should involve looking for signs of corrosion
or local pitting cells. If any is found then a specialist should be
consulted. If after the first inspection the vessel appears sound then
a further inspection should be made after 6 months.
Again, on satisfactory review, inspection can be limited to annually.
When inspecting the internal side of the vessel ensure that the vessel
is first drained of its contents in accordance with the procedures
detailed above.
Before removing the inspection cover ensure that the cover is first
supported by use of the coverplate lifting lug. When re-fitting the
cover, the bolts should be tightened diametrically.

1.1 Safety Points
1. Running
• During operation, the unit may have very hot or very cold
surfaces.
• The temperature probe is installed directly in the secondary flow.
Do not remove when the system is hot, full or under any pressure.
• The equipment has danger from electricity. Do not remove covers
or allow any exposed live parts. Isolate before working on the
unit.
• Take care when lifting. Only use the designated lifting point.
Use only certified lifting equipment capable of lifting the weight.
Water may also be present and spillage could occur.
• Never lift the HT breeze by any associated pipework or pipe
connections.
• Take care when handling, as some of the edges may be sharp.
• Electrical and Mechanical functionality must be considered prior
to connecting any none factory fitted equipment. E.g. Pumps,
Valves / Actuators etc.
Switch on via switch (16)
The front panel will illuminate. After
a few seconds of self checks, the
displays will settle to the Day (1)

1.3 Working Principles
The HT Breeze comprises of a Supapac Plate Heat Exchanger, either a
3 port or 4 port control valve, primary pump, temperature sensor and
PID controller, all mounted on a skid base.
The motorised 3 or 4 port control valve, allows rapid adjustment of the
primary heat input to match changes in secondary hot water demand.
The HT Breeze requires no insulation and the design ensures that the
outlet temperature does not fall below the set point (60°C default but can
be adjusted to suit customer requirements) and consequently reduce the
risk of legionnaires disease.
Providing the class of accommodation and details of the number and
type of fixtures are known, Rycroft will be pleased to recommend the
optimum size of HT Breeze.

Careful consideration must be given to the sizing of stand alone instantaneous water heaters. Standard
demand units incorporate a degree of diversification that would be inappropriate for continuous use
applications.
A more desirable method of sizing for continuous applications is to complete a fixture count and allocate an
appropriate flow for each fitting.
It should also be noted that shower demands for Schools, Sports Centres and Universities should only be
used for medium to large installations. Please refer to our design department for further information.
Table 1
42 single person showers 42 x 4 = 168
55 private hand basins 55 x 1 = 55
9 public hand basins 9 x 2 = 18
3 slop sinks 3 x 4 = 12
15 baths 15 x 4 = 60
Total Demand Units = 313
The shower factors are based upon
intermittent use.
Where certain activities may result
in all showers operating together,
please contact our sales department
for advice.

9 public hand basins 9 x 15 = 135
3 slop sinks 3 x 50 = 150
15 baths 15 x 60 = 900
Total Volume = 4675
Load Factor from Table 3 = 0.7
Total Demand Rate 4675 x 0.7 = 3273 litres/hr
Example of a Hospital Facility
The HT Breeze and Buffer Vessel combination should be sized as follows:-
The Buffer Vessel Capacity = 25% of the total hourly demand. Therefore the required storage capacity
= 3273 x 0.25 = 818 litres. The nearest standard Buffer Vessel sizes are 800 and 900 litres. It is
recommended to go up in size and therefore a 900 litre Buffer Vessel should be selected.
The HT Breeze can be selected as follows:-
Continuous hourly demand = 3273 litres
Specific Heat Capacity of Water = 4.187 kj/kg, °C
Cold Feed Temperature = 10°C
Secondary Flow Temperature = 60°C
Therefore the required kw rating = 3273 x 4.187 x (60-10)
The nearest standard HT Breeze is a CP-B100 which is rated at 209 kw
3600 = 190.3 kw

7
A HT Breeze and Buffer Vessel combination is used when water demand is not constant but high flow
frequently occurs. Boiler power requirements are reduced by storing hot water in the buffer vessel for
peak demands.
The HT Breeze should always be installed with a secondary return line coming back from the system and
into the cold feed line prior to the HT Breeze or Buffer Vessel. This will remove nuisance high limit tripping
due to temperature overshoot, which would occur if the unit was installed on a ‘dead end’ system, when an
outlet was closed. To ensure full heat dissipation, the secondary volume should not be less than that shown
in Table 2.
For larger capacities contact the sales department for advice.
2.1 Sizing and Selection continued.
2. Installation continued
2.2 Installation
Foundations
The HT Breeze should be mounted on prepared foundations that are level.
Lifting
One lifting hole is provided on the top of the HT Breeze control panel.
Avoid the use of chains as screwed connections may be damaged by
the links.
Caution: Never lift the HT Breeze by its pipework or pipe connections.
Pipework
Make sure that the pipework flanges are square and correctly spaced
before bolting up. See that the weight of the pipework is taken by external
supports and not by the HT Breeze. Allowances should be made for
expansion of the pipes either by suitable bends or flexible joints.
Tighten flange bolts in a diametrically opposite sequence and not
consecutively round each flange.
Connections
Threaded connection may be sealed with PTFE tape. Flanged connections
should be sealed with a suitable gasket and sealing agent.
Liquid Expansion
Changes in volume with temperature must not be overlooked. The system
pressure will rise dramatically if there is nowhere for water to expand. It is
not advisable to use a relief valve as a means of releasing the excess water.
Vented systems use the atmospheric vent as an expansion pipe with
discharge back into the tank. Unvented systems require a separate
expansion tank.
Venting
Vent valves must be fitted at the highest point in the connecting pipework so
that the HT Breeze can be bled of air for initial operation. It is essential that
the flooded can type pump motors which are commonly used for all
HT Breeze pumps are bled of air and flooded before starting.
See the pump manufacturer’s instructions.
Filling
Before filling the system
check that the drain valve is
closed and all air vents are
open.
Flush out the system before
installing the HT Breeze to
remove any foreign matter.
Close any manual air vents
and run the HT Breeze.
Crack the vents to release
air
Caution: Do not fill the
system too quickly,
otherwise pockets of air
may become trapped.

2.3 Operation and Set Up Continued.
2. Installation continued
Operation
The HT Breeze is a self-contained unit, which controls up to two primary and two secondary pumps,
together with a three/four-port valve to provide hot water. When the system is fitted with two primary pumps
they are operated on a shared duty-standby cycle with automatic changeover on pump failure.
The HT Breeze can be energised by its own internal time clock function, by a remote switch or Building
Management System or by a combination of the two.
a) Remote Switch or Building Management System Control
The HT Breeze will be turned on when contacts connected to the Remote Enable terminals are
closed. This allows the user to control the time of day when hot water will be available.
When the contacts are open the system is turned off.
b) Internal Time Clock Control
For this function to work the Time clock function should be turned on (see Set Up) and the Remote
Enable terminals should be linked.
Under Time clock control the HT Breeze will be automatically turned on and off at preset times of the
day. Up to two on and two off times can be programmed for each day of the week.
The system can be re-activated after it has automatically switched off by pressing the
Value Increase (7) push button. Each press of this push button will add 30-minute increments to a
total, which is shown in the Time/Alarm window. Pressing the Value Decrease (9) push button will
subtract 30-minute increments from the total time.
The time value counts down and when the time shown has elapsed, the unit will revert to normal time
clock operation.
c) Remote Switch and Internal Time Clock Control
For this function to work the Time clock function should be turned on (see Set Up) and a remote
Control switch should be connected to the Remote Enable terminals.
Under Time clock control the HT Breeze will be automatically turned on and off at preset times of the
day. Up to two on and two off times can be programmed for each day of the week. When contacts
connected to the Remote Enable terminals are opened the HT Breeze will be turned off.
When the system has turned off under time clock control it can be re-activated by pressing the Value
Increase (7) push button. Each press of this push button will add 30-minute increments to a total,
which is shown in the Time/Alarm window. Pressing the Value Decrease (9) push button will subtract
30-minute increments from the total time.
The time value counts down and when the time shown has elapsed, the unit will switch off and revert
to normal time clock operation. However, when the system has been turned off under remote control
it cannot be re-activated by pressing the Value Increase (7) push button.

Night Set Back / Pasteurisation
When the DIP switch for Night set-back/Pasteurisation is set to the on position and the unit into standby.
When set back/pasteurisation value (S Sb to) is set to above normal set temperature (S SET To) the
controller assumes pasteurisation and raises the temperature to the set back/pasteurisation value for one
hour, before returning to standby. Alternatively, when it (S Sb To) is set to below normal set temperature, the
controller assumes set back and lowers the temperature to this value until normal day running begins.
Manual Control
The Advanced Set Up routine allows engineers to position the control valve manually. This feature is active
while this set up window is visible. This feature can be disabled and control restored to automatic by pressing
the Step Left (6), or Step Right (8) push buttons to display another parameter or pressing and holding the
Mode (10), push button to exit the advanced set up routine.
Remote Set Point Adjustment
When a 4 - 20mA signal is connected to the remote input, the set point can be varied between
20 deg c = 4mA and l00 deg c = 20mA. It should be noted that BMS control of the unit starts as soon as the
external signal of above 2mA is detected. Conversely if the controller loses signal, or the signal drops below
2mA it will revert back to it’s own internal set point.
DIP Switch Settings
The physical configuration of the system and the Night Set-back function are programmed into the controller
by setting the position of eight switches. Switches are located on the display printed circuit board.
To change the position of these switches:
1) Isolate the mains supply to the controller.
2) Open the hinged door.
3) Remove the four black fixing screws and slide the control facia out of the enclosure taking care not to
pull the connecting cable.
4) Turn the facia over. DIP switches are located on the bottom edge of the circuit board.
5) Change the switch positions as required (see table below)
6) Replace facia, close hinged door and switch on the mains supply.

3.1 Maintenance
3. Health
A detailed inspection of the HT Breeze should be made after six months.
This provides an insight into future requirements for efficient maintenance. If
the HT Breeze is cleaned and there is no sign of corrosion, it can be safely
assumed an annual inspection will be sufficient for future servicing.
All electrical connections should be checked and tightened if necessary.
Caution:- Maintenance should only be performed by qualified personnel
only. Electrical work should be carried out by a qualified electrician in strict
conformance to the latest requirements.
In order to maintain the HT Breeze unit you will require as a minimum the
following tool kit:
• Set of Metric allen Keys up to M16
• Set of Metric spanners
• Set of Screwdrivers
• A pipe wrench to suit a maximum 50mm nominal pipe size.
• M16 friction ratchet and M16 deep ring spanner (CP-B25 to CP-B250)
Controller
The controller is run via an EPROM that stores all the changes to the time
programmes and other data.
After the first six months, all connections in the panel should be checked
and tightened if necessary.
Temperature Thermocouple
Ensure that the Thermocouple connections are satisfactory.
Refer to the manufacturer’s instructions.
Control Valve and Actuator
Check that the valve will open and close by using the manual facility on the
controller. Electrical connection should be checked at the actuator. The
linkage should also be tightened to ensure good mechanical contact.
Refer to the manufacturer’s instructions.
Hi-Limit Valve and Actuator (if fitted)
Check that the valve opens and closes by turning the power on and off.
Electrical connection should be checked at the actuator. The linkage should
also be tightened to ensure good mechanical contact.
Refer to the manufacturer’s instructions.
Primary Pump
Ensure that the pump is on the correct speed setting and that wiring
is secure at all terminals.
Plate Heat Exchanger
A series of contoured plates with ports form a plate pack with flow
channels. The hot water flows down alternate channels, while the cold water
flows up alternate channels, creating a 100% counter flow.
