Assembly

Installation Guidelines

Safety valve must be installed in the cold water supply pipework before the water heater
The installation must be carried out so that:
- There are no shut-off valves or fittings, narrowing of the pipework or strainers between the water heater and the safety valve
- Good access is provided for service and maintenance
- That the safety valve is positioned above the heat generator
- That between the safety valve and heat exchanger a max. 1 m long straight connection line with the size of the inlet diameter is installed
The safety valve must be mounted so that in its installed condition no external forces act on it
The discharge line must be performed to the size of the safety valve outlet diameter and may not have more than 2 elbows and or be longer than 2 m
The discharge line must be installed with an incline

Assembly instructions

CAUTION!
The safety valve may not be overheated through welding and soldering work on the system. Install the safety valve only after these tasks are completed.

Thoroughly flush pipework
Install the membrane safety valve
• Tighten the connections with max. 18 Nm when joining. Cracks may form in the material when tighten to strongly which may cause leaks in the system.
• Installation in horizontal pipe with safety cap pointing up
• Note flow direction
• Install without tension or bending stresses
Install discharge line
- CAUTION! Risk of scalding through hot liquid escaping from the discharge opening. Route discharge line so that neither personal injuries nor property damage can be caused by discharged fluid. The discharge opening is marked by an arrow on the valve body
Guide the outlet of the discharge line into a drain or container which can accept the total content of the system. If there is a risk that the discharge line becomes clogged or can freeze, interrupt the discharge line, e.g. by a funnel. The discharge line of the funnel must have twice the cross-section of the safety valve intake

Start-up

Mount a warning sign readily visible near the discharge line or on the safety valve with the following text:
- CAUTION! While heating, water must escape from the discharge line for safety reasons. Do not close!
Make sure that all water connections are tight
We recommend flushing the supply line before commissioning the plant

Maintenance

In order to comply with EN 806-5, water fixtures must be inspected and serviced on an annual basis. As all maintenance work must be carried out by an installation company, it is recommended that a servicing contract should be taken out.

Inspection

CAUTION!

Risk of scalding through hot liquid escaping from the discharge opening.
Function check by verifying the response: While the system is operating, briefly open the safety valve by turning the cap. After closing the cap the valve must close again the backed up water drain completely.

Maintenance CAUTION!

Risk of scalding through hot liquid escaping from the discharge opening.
If a malfunction is detected, a repair can be attempted by opening and closing the cap several times. A replacement is necessary if this action is not successful.
