Utica Boilers H2OBT 安装指导

WARNING – When using electrical appliances, basic safety precautions to reduce the risk of fire, electric 

shock, or injury to persons should be followed, including:

1.  This tank must be grounded if any electrical control is used. Connect only to properly grounded outlet. 

2.  Install or locate this buffer tank only in accordance with the provided installation instructions

3.  Use this tank only for its intended use as described in this manual.

4.  As with any appliance, close supervision is necessary when used by children.

5.  This tank should be serviced only by qualified personnel. Contact nearest authorized service facility for 

examination, repair, or adjustment.

The primary application of a buffer tank is to reduce heat pump, chiller, or boiler short cycling. Hydronic buffer tanks are 

used in systems operating below the design load condition, which is most of the time, or in systems having several low 

BTU cooling or heating loads calling at different times. This can cause the heat pump or the boiler to short cycle, resulting 

in reduced operating efficiency and shorter equipment life. 

The hydronic buffer tanks are built with 4 connections. Two connections can be piped to the heat pump or boiler, and two 

connections can be piped to the distribution system. If piped correctly, the tank can serve as both a thermal buffer and a 

hydraulic separator. The heat pump or boiler can be hydraulically decoupled from the distribution system. The tanks are all 

stainless steel construction with R-12 insulation, and an ABS jacket. 
A 3/8” ID thermal well is located mid-tank. Thermistors to be inserted 3” into the well, or the well will accept the Honey-

well L4006A controls.

WARNING:
Do not operate the water heaters in areas where the Ph is above 8.0 or below 6.0, and/or with chloride concentrations 

greater than 100 parts per million (ppm). ECR’s standard warranty does not cover problems caused by improper water Ph 

or excessive levels of chlorides.

DO NOT store or use gasoline or other flammable vapors or liquids in the vicinity of this or any other appliance.
If you smell gas vapors, DO NOT try to operate any appliance - DO NOT touch any electrical switch or use any phone in 

the building. Immediately, call the gas supplier from a remote located phone. Follow the gas supplier’s instructions or if the 

supplier is unavailable, contact the fire department.
