The Standalone system consists of the following components:

- A Glow-worm Envirosorb 5 heat pump,

- A "Standalone" hydraulic module,

- The Systempro control unit

- A Climapro2 RF wireless programmable room thermostat,

- A wireless photovoltaic outdoor sensor

The following options may be added to the system:

- 2 port valves for zoning,

- A domestic hot water cylinder.

2.1.1 Operating principle in heating

The system is designed to provide a heating need of 6kW max at the reference temperature.

The heat generator consists of a heat pump and a hydraulic module equipped with an electric heater. The heat emitters can also be low temperature (heated fl oor, gentle heat radiators...) or medium temperature (steel panels...). In order to always obtain the best comfort/economy trade-off, the module heat pump and/or electric heater supply the heating installation with hot water at the temperature necessary to obtain the desired ambient temperature.

When the power of the heat pump is insuffi cient to provide heating, the self-controlled electric heater in the module can operate simultaneously, up to a power of 4kW, as a backup. This guarantees optimal use of the heat pump while guaranteeing that the total electrical power consumption will never exceed 6kW. When the heat pump is not operating, the electric heater can reach a power level of 6kW.

The changeover point between the heat pump and the electric heater is managed automatically, depending on the outside and ambient temperatures. Thus, the system always optimises the use of the heat pump with respect to the electric top-up heater.

2.1.2 Operating principle of the domestic hot water system

The domestic hot water heating circuit consists of a heat pump, a 3-way valve and a FLUROCYL hot water tank equipped with an electric heater.

In order to always obtain the best comfort/economy trade-off, the heat pump and/or the FLUROCYL tank electric heater provide the energy needed to maintain the stored water at the required temperature.

The lower part of the tank is heated 3 times a day by the heat pump. In order to provide maximum economy, the electric heater heats the top part of the tank just to provide the comfort desired by the user.

The lower the hot water temperature setting, the more the heat pump will provide energy and, therefore, more economic operation.

INSTALLATION

4 System appliance installation

4.1 Recommendations before installing

4.1.1 Heating circuit design

General

The heat transmitters may be low temperature (eg underfl oor heating or high temperature (radiator...).

The pipe sections are to be determined using a fl ow / pressure curve (refer to the chapter "Activating the control unit" ►

Commissioning ► Heating circuit adjustment"). The distribution will be determined by the fl ow corresponding to the power actually required, regardless of the maximum power that can be provided by the installation’s generators.

b

We recommend that you allow for suffi cient fl ow to ensure that the temperature difference between the fl ow and the return is equal to 7 K for fl oor heating and 15 K for radiators.

b

Make sure the heating circuit water fl ow is greater than 900 l / h.

Installation pipework must be designed and installed to ensure venting of air from the system is possible.

b

TRVs must be fi tted on all radiators, with the exception to reference rooms.

The total volume of water for the heating circuit depends, among other factors, on the cold static load of the Hydraulic module's expansion vessel.

i

The heating system volume should be calculated to ensure that the expansion vessel is suitable, it may be necessary to add an additional vessel.

- In GB, Guidance on vessel sizing is also given in the current issue of BS5449 and BS7074 Part 1.

Il est recommandé de prévoir un robinet de vidange au point le plus bas de l’installation.

- Drain taps shall be to the current issue of BS2879.

It is recommended that a drainage valve be installed at the lowest point of the installation.

- Drain taps shall be to the current issue of BS2879.

• Install the following components in the return of the heating circuit (not supplied):

- a heating fi lter

- a ¼ turn shut-off valve,

- an air separator (if necessary),

- an anti-sludge fi lter (if necessary).

• In the case of a heated fl oor, install a manual reset overheat safety device (55°C) on the heating circuit fl ow (refer to the

INTRODUCTION

Chapter - System description). Connect the overheat safety device to the electric supply for the module circuit board

(refer to the module installation manual).

Water treatment

Existing system

- It is essential that prior to installing the new appliances the system is thoroughly fl ushed.

New system

- For optimum performance after installation, the appliances and its associated central heating system should also be fl ushed.

Flushing shall be carried out in accordance with BS 7593, a chemical cleanser can be used either Sentinel X300, X400 or

Fernox F3 are suitable.

It is recommended to fl ush existing systems fi rst before fi tting the new appliances.

• Ensure all cleanser is removed from the whole system before adding an inhibitor.

For long-term corrosion protection after fl ushing, an inhibitor suitable for stainless steel heat exchangers can be used. Either

Sentinel X100 or Fernox F1 inhibitor can be used.

The module is suitable for use on systems using softened water.

4.1.2 Heat pump circuit design

Installation pipework must be designed and installed to ensure venting of air from the system is possible. b

Make sure the circuit’s water fl ow corresponds to the appliance’s nominal water fl ow.

• Install the following components to the hydraulic module, in the direction of the heat pump (not supplied):

- a fi lter,

- a ¼ turn shut –off valve on each side of the fi lter,

• Install a ¼ turn shutoff valve in the fl ow of the heat pump.

i

In order to avoid the transmission of vibrations to surrounding structures, use hoses for the hydraulic connections at least 1 metre from the heat pump.

b

4.1.3

Insulate the pipes with an UV- and hightemperature-resistant insulation.

Domestic hot water circuit design

Water pressure

The maximum working pressure of the domestic hot water circuit is 10 bar. If the cold water supply pressure exceeds this, then a pressure-reducing valve must be fi tted in the supply to the boiler.

‘Hard’ water areas

In areas where the water is ‘hard’ (i.e. more than 200 mg/L of calcium carbonate), it is recommended that the hot water setting is reduced and that a scale reducer is fi tted, refer to the manufacturer’s instructions or consult the local water company for additional advice.

INSTALLATION

5.3.1 Domestic hot water pipework

• Connect the hot water outlet to the 22mm hot water connection of the cylinder.

• Lay a further 22mm pipe to the fi rst T-piece.

A pipe of 15mm diameter should then be suffi cient.

• If the pipe is very long or several outlets are supplied, continue with another 22mm pipe.

5.3.2 Thermostatic mixing valve

A hot water thermostatic mixing valve ensures the hot water from the cylinder is mixed with cold water to a desired maximum temperature between 30°C and 60°C.

• Set the thermostatic mixing valve to the desired maximum temperature during the system commissioning.

a

Risk of scalding! Set the thermostat mixer to

60°C or below and check the temperature at a hot water tap to ensure effective protection against scalding.

5.3.3 Mains water supply

The performance of unvented cylinders depends on the available mains water pressure and the pipe size.

In order for the performance of the Flurocyl cylinder to be ideal, an appropriate cold water supply must be available.

The measured static pressure must be at least 2.0 bar. A corresponding fl ow rate of at least 20 - 25 l/min should be available.

NOTE: The mains water pressure is reduced during periods of high water consumption. Make sure you take measurements during these periods.

Example: The available fl ow rate of mixed water at 40°C is 25 l/min (15 l/min hot water of 60°C from the cylinder mixed with

10 l/min cold water of 10°C) if the measured static cold mains water pressure is 2 bar.

The cylinder operates satisfactorily at a mains water pressure of below 2 bar, but at a reduced fl ow rate. The unvented cylinder should not be installed if the mains water pressure is below 1 bar. You can obtain information on alternative hot water supply systems from Glow-worm.

To keep the friction losses at a minimum, a minimum diameter of 22mm is recommended for the cold water supply in the building, satisfactory performances can also be achieved with

15mm pipes however.

5.3.4 Cold water inlet controls and pipework

• Connect both parts of the water control pack.

• When installing the valves, make sure they are aligned in such a way that the 15mm connection of the expansion relief valve can be connected to the tundish.

• Install the assembled water control pack in the cold water supply at an appropriate place next to the cylinder.

• Make sure there is suffi cient space for maintenance and the connection of the discharge pipe from the expansion relief valve.

• Install the drain valve in the cold water supply at the lowest point between the cylinder and the water control pack.

We recommend applying a hose, which reaches about 1m under the base of the cylinder, to the outlet of the drain valve.

b

Risk of bursts for the cylinder! No stop valve may be installed between the cold water control pack and the cylinder.

• Install the water pack so that a discharge pipe of the expansion relief valve can be fi tted with constant outward slope which can end at a safe, visible point where there is no risk of freezing.

b

Risk of the cylinder bursting due to overpressure! The outlet of the expansion relief valve must not be covered or closed.

• Test the expansion relief valve regularly to avoid calcifi cation.

To ensure an optimum performance of the cylinder, in particularly buildings in which a pressure controlled cold water is used, copper pipes with a diameter of at least 22mm should be used for the pipe from the main stop valve of the building to the cylinder.

If the discharge pipes are all together, the expansion relief valve may not be installed more than 500 mm away from the temperature and pressure relief valve.

The Flurocyl cylinder is supplied with an external hot water expansion vessel (DW EV).

• Connect this expansion vessel to the installed water control pack as follows:

• Screw the expansion vessel directly onto the water control pack, via the connection intended for this purpose or

• Connect the expansion vessel to the water control pack with a copper pipe or an appropriate hose. Make sure the expansion vessel is supported suffi ciently.

• Use the supplied mounting bracket if the expansion vessel is to be mounted on the wall.

• Connect thermostatic mixing valve cold supply to the pressure controlled cold water connection of the water control pack (if convenient).
