Frequently Asked Questions - SG150D HONEYWELL

What is the difference between the SG150 and SG150D models?

The SG150D model incorporates a pressure reducer, unlike the SG150 which does not have one. Refer to the manual for exact variants.

What sizes are available for this valve?

The valve is available in 1/2" and 3/4" sizes. Check the label on the device to know yours.

How to adjust the downstream pressure on the SG150D?

Close the inlet valve, depressurize the outlet, loosen the slotted screw, turn the adjustment handle to the desired value (min. 1 bar below upstream pressure), then retighten the screw.

How often should the valve be maintained?

The safety valve must be purged every 6 months. The pressure reducer and check valve should be checked once a year. Complete maintenance by a professional is recommended every 1 to 3 years.

What to do if the valve drips constantly?

Operate the purging device several times to rinse out particles. If that is not enough, the check valve or seals may be dirty: have them replaced by a professional.

Can I adjust the safety valve?

No, the safety valve is factory-set (6, 8 or 10 bar) and is not adjustable without destroying the valve. Do not attempt to modify it.

What type of fluid is compatible?

The device is designed for water only. Do not use it with other fluids.

How to clean the filter of the valve?

Close the shut-off valves, depressurize, unscrew the strainer bowl with the ZR06K key, remove the filter, clean it, put it back and screw the bowl back on.

Where to install the combined safety valve?

Install it on the cold water pipe upstream of the water heater, horizontally or vertically. Ensure easy access for maintenance and proper drainage.

What accessories are recommended?

A pressure gauge (M08M) to check pressure, a double hex key (ZR06K) for disassembly, and a fitting set (VST06-A/B) for installation.

2. Use the appliance
   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.
