a Risk of scalding and bursts due to inappropriate alterations!
There is a risk of escaping steam, bursting, and damage to the system if you make any changes to the cylinder, control system, supply lines for water and power (if present), relief valve termination, or expansion relief valve for the cylinder water.
Do not make any improper changes.
a Risk of scalding!
The output temperature of the draw-off points can reach 85 °C if the mixing valve is set incorrectly.
- Do not adjust the mixing valve.
- If the output temperature at a draw-off point is too high or low, Contact an engineer qualified to work on unvented systems to adjust the temperature.
Risk of damage from leaks!
Leaks on the water pipes between the cylinder and tap can result in water damage.
- If a leak occurs, close the cold water stop valve on the cylinder.
- Contact an engineer qualified to work on unvented systems, to eliminate the leak.

4.1.1 adjusting the cylinder thermostat

Key1 cylinder thermostat
Ifnocontrollerforhotwatertemperaturecontrolisinstalled,youcansettherequiredhotwatertemperatureonthecylinderthermostat(1).Youcansetthereheatingtimesontheinstalledtimer.Refertotheoperatingmanualforthetimer.
• Setthedesiredcylinderhotwatertemperatureonthecylinderthermostat(1).
• Foroptimumefficiency,chooseasettingof45°C.
• Usetheoperatingmanualforthegas-firedboilertomakesurethattheunitisreadyforoperation.
We recommend the cylinder is set to 60 °C periodically, to provide protection against the proliferation of harmful bacteria.
If you are heating up water for the first time or after a long switch-off period, the full cylinder performance is only available following a waiting period.
If the Hydracyl is installed in a cupboard, make sure that clothing and other objects are not placed on the cylinder, control devices, pipes, or other system components.
Always make sure that there is clear access to the cylinder to enable the use of the hot water thermostat controller and the thermostat mixer.

4.3 frost protection
Risk of damage due to frost!
If the cylinder is placed out of operation for a relatively long period of time in an unheated room (e.g. during a winter holiday), the cylinder must be completely drained.
- Contact an engineer qualified to work on unvented systems to drain the cylinder.

a Where cylinders are fitted high up in the building there are some situations where a vacuum could be created in the cylinder. The installer must consider in these circumstances the necessity of fitting an anti vacuum valve to prevent cylinder damage. This valve allows air to enter the cylinder if the pressure becomes too low due to draining or thermal contraction.

INSTALLATION
10 cylinder installation
a Improper installation can impede the operational safety of the unit.
- Only an engineer qualified to work on unvented systems may install and start up the unit. This person takes responsibility for making sure that the unit is installed and commissioned for the first time correctly and in accordance with regulations.
a There is a risk of burns from system pipes without thermal insulation. Energy losses also occur in such cases.
- Provide all system pipes with thermal insulation.
- Use screw connections to close all connection lines.
Improper use and/or unsuitable tools may result in damage to property (e.g. gas or water leaks).
- Always use a suitable open-ended spanner to tighten or undo threaded connections.
-Do not use pipe wrenches, extensions, etc.
Mechanical stress on supply lines can result in leaks and thus damage to the heat pump.
- Avoid mechanical stress on supply lines!

Where possible, avoid installing a circulation line, since acirculation line results in higher energy consumption.
If you are not using the circulation connection, you must ensure that it is properly closed off. Where secondary return circuits are used, an additional expansion vessel may be required.

In regions with high water pressure (4 bar or more), you can also connect the mixer tap for a bath or shower to the cold water connection with pressure compensation (3) of the safety assembly. This ensures that the hot and cold water supply to the mixer tap have the same pressure. You should install the cold water supply for all other connections using a T-piece before the safety assembly in the cold water pipe to the cylinder.

e Improperly executed work on the cylinder can result in a danger to life and limb.
- Malfunctions may only be rectified by an engineer qualified to work on unvented systems.
Not all electric immersion heaters have a safety thermostat.
- Only use Glow-worm electric immersion heaters with a safety thermostat as replacement parts.

13.1 Taking the cylinder out of service
13.2 Temporarily taking the cylinder out of service
Risk of damage as a result of the cylinder freezing! Frost protection and monitoring devices are only active while the boiler is connected up to the power supply.
- Make sure that the cylinder cannot be damaged if there is a frost.
• Temporarilytakethecylinderoutofservicebyswitchingtheboileroff.
13.3 Permanently taking the cylinder out of service
e Risk of fatal electric shock from live connections! Voltage is continuously present on the mains connection terminals of the boiler.
- Interrupt the power supply.
- Prevent the power supply from being switched on again.
- Ensure that any electrical work is carried out by a competent person approved at the time by the Health and safety Executive.
