Frequently Asked Questions - SG150 HONEYWELL

What to do if the safety valve drips constantly?

Actuate the purge device several times to flush out dirt particles. If dripping persists, replace the check valve or the valve assembly.

How to adjust the downstream pressure of the reducer?

Close the shut-off valves, depressurize the outlet side, loosen the slotted screw (do not remove it), turn the adjustment handle to the left until it stops, then slowly open the inlet and adjust to the desired value. Retighten the screw.

What is the maximum upstream pressure?

The maximum upstream pressure is 16 bar for the SG150D model. Refer to the variant table.

What are the recommended maintenance intervals?

The safety valve should be tested every 6 months. The decompressor and check valve once a year. Full maintenance by a professional every 1 to 3 years.

Can the valve be mounted vertically?

Yes, the mounting position can be horizontal or vertical, provided the flow direction is respected and easy access for maintenance is guaranteed.

How to clean the valve filter?

Close the water supply, depressurize, unscrew the strainer bowl using the polygonal wrench ZR06K, remove the filter, clean it and reassemble. Do not use solvents or alcohol.

What to do if the downstream pressure is unstable?

Clean the replacement strainer. If the problem persists, check the condition of the nozzle or sealing washer and replace the valve trim assembly if necessary.

What tools are needed for maintenance?

A double polygonal wrench ZR06K is required to disassemble the spring cover and the filter strainer bowl. A pressure gauge can be used for calibration.

Is the valve suitable for hot water?

Yes, the maximum operating temperature is 40 °C. It is suitable for closed water heaters up to 200 L.

How to know if the check valve is defective?

Close the outlet valve and open the check valve. If water continues to flow instead of stopping after a few seconds, the check valve is defective and must be replaced.

   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

Safety groups of this type combine pressure reducing valve (only SG150D), check valve, shutoff valve, test point and diaphragm type safety valves in one appliance.

Flow first passes through the pressure reducing valve which operates on a force equalising system whereby the force of a diaphragm operates against the force of an adjustment spring. The inlet pressure has no influence on either opening or closing of the valve and therefore inlet pressure fluctuations have no influence on the outlet pressure. The check valve has a movable valve disc which pushes against a spring when flow occurs.

The downstream safety valve is a direct operating safety valve. That is, the opening force operates against the force of a spring.

The shutoff valve enable the check valve to be checked and serviced.

7. Assembly

7.1 Installations Guidelines

• Safety group must be fitted in the cold water supply to the hot water storage unit
• Installation in horizontal or vertical pipeline possible
• 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 The safety valve is fitted above the top of the water heater to avoid the need for draining down when exchanging the safety valve insert

• If there is no drainage facility in the room where the heater is installed, then the safety valve may be fitted in an adjacent area. DIN 1988, part 2 is to be observed
• Distance to the water heater approx. 1m
• While heating, water must escape in the discharge line for safety reasons. Do not close off!
• The drain line of the membrane safety valve must be viewable!
• If the drain guide is not connected directly with the safety group, a discharge line must be installed between the safety group and the drain guide!
• The discharge line must be performed to the size of the safety valve discharge cross-section and may not have more than 2 elbows and or be longer than 2m !
• If, for compelling reasons, more elbows or a greater length becomes necessary, then the entire discharge line must be designed to a larger nominal width. More than 3 elbows, as well as lengths over 4m are not permitted!
• The discharge line must be installed with an incline!

7.2 Assembly instructions

1. Blow out or rinse pipe line out well
2. Install safety group in the cold water line o Note flow direction o Install without tension or bending stresses

1. Troubleshooting

Problem	Cause	Remedy
SG150 and SG150D
Drips	During the heating up of the water heater	no error, normal function
	Continually drips from soiling	Actuate lifting grip multiple times so that dirt particles are flushed out, or replace as necessary
Backflow stopper does not close off tightly in the front pressure area.	Pressure increase in the front pres-sure area	Replace backflow stopper
	Seal surfaces dirty or worn	Replace backflow stopper
Too little or no water pressure	Cut-off fixtures before or after the safety group not opened entirely	Open the shutoff valves fully
	Safety group not installed in the flow direction	Install safety group in flow direction (observe arrow direction on housing)
only SG150D
Water is escaping from the spring bonnet	Diaphragm in valve insert is faulty	Replace valve insert
Too little or no water pressure	Pressure reducing valve is not set to the desired outlet pressure	Set outlet pressure
	Filter in pressure reducing valve is contaminated	Clean or replace filter
The outlet pressure set does not remain constant	Filter in pressure reducing valve is contaminated or worn	Clean or replace filter
	Valve insert, sealing ring or edge of nozzle is contaminated or worn	Replace valve insert
	Rising pressure on outlet (e.g. in boiler)	Check check valve, safety group etc.
	Expansion water from the hot water purifier	Inspect backflow stopper before the hot water purifier and single-lever mixing valve if necessary.
		Close shut-off valves to the hot water puri-fier supply line. Open hot water tap connec-tion. Does pressure remain constant? Expansion water of the hot water purifier. Does pressure increase? Pressure reducer defect.
