Page 6: Pre-Installation Considerations
II. Pre-installation Considerations Inspect shipment carefully for signs of damage. All equipment is carefully inspected and packed. ECR’s responsibility ceases upon delivery of the water heater to the carrier in good condition. Any claims for damage or shortage, must be filed immediately against the carrier by the consignee. No claims for variances or shortages will be allowed by the Manufacturer, unless they are presented within sixty days after receipt of the equipment. - Page 7 Circulator Sizing. Refer to Table 2 for the minimum flow through the water heater coil and the pressure drop at minimum flow. Calculate the pressure drop across all piping and fittings connected to the water heater zone. Be sure to include all zone valves, check valves, and shut-off valves.
- Page 8 Locating the water heater. The water heater should be located in an area where water leakage from the tank or connections will not result in damage to areas adjacent to the water heater or to lower floors of the structure. When such a location can not be avoided, a suit- able drain pan must be installed under the water heater, and the drain pan must be connected to a drain.

Page 9: Piping
Water Quality Improper water quality will reduce the expected life of the water heater. Hard water, sediment, high or low Ph, and high levels of chlorides in the domestic water should be avoided. Sediment and hard water will eventually coat the heating coil inside the water heater and reduce the rate of hot water production and may, eventually cause a failure. - Page 10 Water boiler piping. See Figures 2 and 3. Determine where the boiler, the space heating, and the water heater connections should be made based on the type of piping system that is either in place, or is to be installed for a new hydronic system installation. See Figure 2, Boiler Water Piping with Zone Circulators, and Figure 3, Boiler Water Piping with Zone Valves.

IV. Electrical Install electric wiring and grounding in accordance with the National Electrical code and local regulations. All water heaters are supplied with a thermostat. Refer to wiring schematics for separate circulator wiring. Refer to wiring schematics for zone valve wiring. Reference should be made to the Installation Manual for the boiler as well. - Page 16 Argo offers a broad line of controls for water heating and multiple zone boiler heating applications. Please check out our web site at http://www.argoindustries.com for applications information and compre- hensive wiring diagrams. A typical wiring diagram is shown below. This is a multi-zone application using zone pumps with program- mable domestic hot water priority using our ARM-4P Panel.

Page 19: Maintenance
VI. Maintenance The water heater is intended to provide many years of reliable service. Components, such as thermostats and relief valves, may be subject to failures that require service. Depending on the quality of the water supply, sediment and/or scale may coat the heating coil in the tank and reduce hot water recovery rate. Failure to use the correct procedures or parts can result in unsafe operation. - Page 20 180 deg. F Boiler Supply 180 deg.
