   according to its intended use
3. in good condition
   with due regard to safety and risk of danger.
4. Note that the appliance is exclusively for use in the applications detailed in these installation instructions. Any other use will not be considered to comply with requirements and would invalidate the warranty.
5. Please take note that any assembly, commissioning, servicing and adjustment work may only be carried out by authorized persons.
6. Immediately rectify any malfunctions which may influence safety.

2. Functional description

Diaphragm safety valves of this type are directacting safety valves in which the disc is pushed up by the pressure from the system against a spring which is holding the valve closed. If the opening force exceeds the force exerted by the spring, then the valve disc is lifted off the valve seat and the valve discharges the medium. In accordance with the requirements of the standard, the full discharge capacity of the valve will be achieved when the system pressure climbs to no more than 10% above the set pressure of the valve. Full shutoff must be achieved if the system pressure falls to below 80% of the nominal set pressure of the valve. For valves rated up to 3.0 bar, the closing pressure can be taken as 0.6 bar minimum.

3. Application

The membrane safety valve is only suitable to drain drinking water from closed hot drinking water systems according to DIN 1988 and DIN 4753-1 for protection against exceeding pressure

Medium Water

6. Scope of delivery

The safety valve comprises:

Angled housing
- Adjustment spring
- Diaphragm
- Security cap with part label

7. Assembly

7.1 Installations Guidelines

• Safety valve must be installed in the cold water supply pipework before the water heater
• The installation must be carried out so that:

o There are no shutoff valves or fittings, narrowing of the pipework or strainers between the water heater and the safety valve
o good access is provided for service and maintenance
o that the safety valve is positioned above the heat generator
o 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 2m
• The discharge line must be installed with an incline

7.2 Assembly instructions

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.

1. Thoroughly flush pipework
2. Install the membrane safety valve

o 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.
o Installation in horizontal pipe with safety cap pointing up
o Note flow direction
o Install without tension or bending stresses

1. Install discharge line

Risk of scaling 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

1. 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

8. Commissioning

1. Mount a warning sign readily visible near the discharge line or on the safety valve with the following text:

While heating, water must escape from the discharge line for safety reasons. Do not close!

1. Make sure that all water connections are tight
2. We recommend flushing the supply line before commissioning the plant

9. Maintenance

In accordance with DIN 1988, Part 8, the following operations should be carried out regularly. A planned maintenance scheme is recommended.

9.1 Inspection

To be carried out by an installation company or the operator.

Frequency: every 6 month

Risk of scaling 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.

9.2 Maintenance

To be carried out by an installation company Interval: once a year Risk of scaling 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.

10. Disposal

• Brass housing
  Spring steel adjustment spring
  High grade synthetic material security cap
• Hot water resistant elastomer diaphragm

Observe the local requirements regarding correct waste recycling/disposal!
