The AM2V package consists of an outdoor unit, an indoor unit and buffer tank. A DHW storage tank is available as an option. The outdoor unit is of a monoblock design with the refrigeration system totally contained in the outdoor unit eliminating any refrigeration piping and charging between the outdoor unit and inside the house. The indoor unit contains hydronic system components and controls to simplify the piping of the hydronic system. It also contains an integral electric supplement heater if added capacity is needed under cold weather conditions. In the heating mode the AM2V can provide heating water temperatures up to 140º F and in cooling a chilled water temperature of 45º F. Performance is dependant on outdoor temperature and system water temperature.

Minimum Clearances to Combustibles Top Front Rear Left Right 0 0 AL, CL 0 0 0 Mounting the Indoor Unit AL = Alcove CL = Closet Installing the wall mounting bracket The indoor unit can be wall-mounted on a concrete wall. Note: The enclosed screws and rawl plugs are only suitable for concrete. For other construction materials, use bolts and anchors that are suitable for 100 lb. (46 kg) loads. Installation of mounting bracket on brick/concrete wall 1. Mark out the rawl plug holes. 2.Drill holes 3/8 in. ( 10 mm) and insert the rawl plugs supplied. 3.Fit the wall mounting bracket with the screws supplied. 4.Mount the indoor unit on the wall mounting bracket. Ensure that both tabs have locked into the indoor unit. NOTE Check the condition of the wall where the indoor unit is to be installed. For the suitability of the supplied rawl plugs for various building materials, see the manufacturer's instructions. For other construction materials, use fixing materials with sufficient load bearing capacity. CAUTION Whichever mounting method is used, ensure that the bracket is tightly and securely fastened to wall. Failure to secure indoor unit properly could cause indoor unit to loosen, posing a severe safety hazard. 11 Vitocal 100-AW AM2V Application Guide Recommended Minimum Service and Operational Clearances AM2V 020028/034043 Outdoor Unit Back to Index Legend A Air Outlet B Air Inlet Dimensions in.
