PREREQUISITE
When installing this product...
1. Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous

Preparation
CAUTION
Equipment Damage Hazard
Foreign particles like dirt and metal chips can damage the valve seat and diaphragm.
For trouble-free operation of the product, good installation practice must include initial system flushing and chemical
water treatment. Clean the lines upstream of particles larger than 1/16 inch diameter (welding slag, pipe scale, sand,
and other suspended particulate).
Do not use boiler additives, solder flux, and wetted materials which are petroleum-based or contain mineral oil,
hydrocarbons, or ethylene glycol acetate. Compounds that can be used, with a minimum 50% water dilution, are
diethylene glycol, ethylene glycol, and propylene glycol (antifreeze solutions).
If installing these valves in an addition to, or retrofitting an existing building, do not assume that the fluid in the existing
piping meets these criteria.
1. Before installing the valves, flush the system.
2. It is recommended to install strainers in front of the valves to protect against clogging due to foreign particles.
Strainer baskets should be installed, checked and cleaned as required during flushing and normal operation.
3. Use clean water according to the guidelines in VDI 2035. VDI 2035 recommends water quality as per
conductance value <100 μS/cm, oxygen content of up to 0.1 mg/l, pH of 8.2-10.0 and requires low turbidity
<1FTU and consequently low content of alkaline earths.
4. It is recommended to treat water with chemical to achieve required water quality. If using any additives, please
contact Honeywell for guidance.
