FunctionPressure reducing valves are installed in residential water systems to reduce and stabilise inletpressure from the water mains supply which is generally too high and variable for domesticappliances to function properly.

These valves can also be used to control inlet pressure to domestic hot water storage.

The Caleffi 5335 series have been specifically designed andmanufactured to meet the requirements of AS1357.2:2005 Valvesprimarily for use in warm and hot water systems - P. 2: Control valves.

Recommendations for installation

1. Installation below groundIf installing the 5335 series valve underground, please ensure that steps are taken to protect thevalve from becoming frozen in frost-prone areas.Please allow yourself sufficient space to remove the cartridge should maintenance be required.

The reading of a gauge for setting purposes may be difficult and an alternate means of checkingdownstream pressure may ne necessary.

2. Water hammering

This is one of the main problems which may affect pressure reducing valves. It is best to fitspecial devices to absorb water hammering when fitting pressure reducing valves in systems at risk.

WARNING:If it is critical to maintain the downstream pressure setting to protect equipment, asa safety measure, we recommend that a pressure, or safety, relief valve is installeddownstream of the pressure reducing valve.

Trouble-shooting

1. Increased downstream pressure near a waterheater

This problem is due to the water being heated bythe water heater. There is no relief of the pressurebecause the reducing valve is correctly closed. Thesolution is to install an expansion vessel (between theheater and the reducer) to absorb the pressureincrease.

2. The pressure reducing valve does not maintain its set pressure

In most cases this is the result of impurities that deposit on the valve seat causing leakagewith a resulting increase in pressure downstream. The solution is to fit a filter upstream fromthe reducer and subsequently to maintain and clean the cartridge (see Maintenance ).

1. Flush the system.

2. Install the pressure reducing valve in any position either vertically or horizontally, not upsidedown, paying attention to the direction of flow indicator on the body of the valve.

3. Caleffi 5335 series pressure reducing valves are factory set at 500 kPa.

4. If required, reset the pressure by turning the screw on the top of the plastic cover. Turn it clockwise to increase the pressure andanticlockwise to decrease it.


5/6

SafetyIf the pressure reducing valve is not installed, commissioned and maintained properly inaccordance with the instructions contained in this manual, it may not operate correctly,and may cause damage to objects and/or persons.

Make sure that all the connections are water-tight.

When installing the pressure reducing valve, make sure not to over-tighten the connections to thevalve as, over time, a failure can occur with subsequent water leakage causing damage.

In the case of highly aggressive water, arrangements must be made to treat the water before it entersthe pressure reducing valve, in accordance with current legislation. Otherwise, the pressure reducingvalve may be damaged and not function correctly.

Leave this operating manual with the user

Maintenance

Proceed as follows for periodic cleaning of the strainer and inspection of the cartridge:

1 Turn off upstream water supply to the pressure reducing valve and open an outlet downstreamto relief pressure

2 Unscrew (anticlockwise) the setting screw to decompress the spring inside.3 Unscrew the cover.4 Extract the cartridge with the aid of pincers to grip the head of the screw.5 After inspection and cleaning, refit the cartridge or, alternatively, fit a replacement cartridge.6 Reset the valve (see Installation ).
