2 Readit carefully before using the air handler. Then keep ithandy for quick future reference by inserting it in theplastic envelope provided on the PlateA rating plate identifying the air handler will be foundinside the front access panel. A rating plate identifying thewater heater will be found above or to the left of the gascontrol valve. When referring to the air handler and/orwater heater, always have the information listed on therating plate readily take the time to read not only this manual but alsothe warranty sheet enclosed. Warranty of parts and the airhandler will depend on the proper installation,maintenance and operation of the air , the warranty shall be void if the design orstructure of the air handler is, or is attempted to be,modified or altered in any way, including, but not limitedto, by attaching non-Company approved appliances manufacturer of this air handler will not be liable forany damages because of failure to comply with theinstallation and operating instructions outlined on thefollowing pages.

3 Use them as a guide to check thepropriety of the air handler will need to maintain the air handler and waterheater as outlined in this in this carton was inspected and verified to bein good condition at the time it left the factory. Whenreceived, a visual inspection of the equipment should bemade and any damage noted on the delivery receipt. Adamage claim should then be filed immediately with AIRFLOWHORIZONTAL AIRFLOWHow the System WorksThis section will answer many of the most often askedquestions about the does it work?The heating system uses a gas water heater to furnish heatto the space of a residence, as well as its domestic hotwater. A simple recirculating loop of hot water is tapped offnear the top of the heater and is circulated through a finnedtube heat exchanger in an air handler or duct coil thatfurnishes warmed air to the space.

4 The cooled water (140 cooled to about 120 ) is then returned to the water heater,near the bottom of the tank. Each air handler includes acirculating pump and controls, factory piped and water heater may include side tappings to provide therecirculating loop connections. When a conventionalheater is used, special fittings including check valves areused at the hot and cold water control of the heating system is very simple. Aconventional heating or heating/cooling thermostat is a call for heat, the hot water circulator is energizedthrough a relay, as is the blower motor. Hot waterimmediately begins circulating through the heat exchanger,and heats the air. Typical leaving air temperatures are 95 105 . When the thermostat is satisfied, the pump andblower both is a Hydro Heat System sized?

5 Proper sizing of the water heater is essential, and beginswith the ACCA Manual J design heat loss of the structure tobe heated. The heating capacity of the air handler of coilselected must be equal to or larger than the design heatloss. Then, the water heater selected must have a heatoutput equal to or greaterthan the coil or air handlerheating a Hydro Heat System require a larger tank size?In general, it does notrequire a larger tank sizeto furnishspace heat as well as domestic water. When propercalculation has been made to determine the BTUH inputrequired, and the heater has been selected on that basis,the tank size must be no smaller than 40 gallons, andshould be at least that normally used for the expectedoccupancy of the -120 WATERAPOLLO AIRHANDLERCOOLING COILHOT WATERTO HOUSECOLD WATERINGASWATER HEATER120 -140 WATERPUMPHEATEXCHANGERBLOWERCONDENSATEDR AINPAN105 -120 WATERAIR HANDLERCOOLING COILHOT WATERTO HOUSECOLD WATERINGASWATER HEATER120 -140 WATERPUMPHEATEXCHANGERBLOWERCONDENSATEDR AIN PAN2 Table of ContentsRating the System for the New.

7 Water heated to atemperature which will satisfy space heating, clotheswashing, dish washing, and other sanitizing needs canscald and permanently injure you upon contact. Somepeople are more likely to be permanently injured byhot water than others. These include the elderly,children, the infirm, or physically/mentallyhandicapped. If anyone using hot water in your homefits into one of these groups or if there is a local codeor state law requiring a certain temperature water atthe hot water tap, then you must take specialprecautions. In addition to using the lowest possibletemperature setting that satisfies your hot water needs,a means such as a mixing valve, shall be used at the hotwater taps used by these people or at the water valves are available at plumbing supply orhardware stores.

8 Follow manufacturers instructions forinstallation of the valves. Before changing the factorysetting of the thermostat read the TemperatureRegulation section in this not use this appliance if any part has been underwater. Immediately call a qualified service technicianto inspect the appliance and to replace any part of thecontrol system which has been under for the New InstallationNote: Information in this section is generic. Refer to Setting Equipment section of this manual for specific may be up to 70 of separation between the airhandler and water heater. The location selected for thewater heater should be as close to the stack or chimneyas practical, and as centralized with the piping system forthe air handler as possible.

9 They (air handler/waterheater) should be located in an area protected from installations in areas that may experience freezingtemperatures, care should be taken to protect equipmentfrom freezing, and dwelling from water damage, shouldfreezing occur. See Low Temperature Protection Switch on page : The locations selected should provide adequateclearances for servicing and proper operation of the to CombustibleMaterialsThe air handler can be operated with 0 of clearance tocombustible materials from any side, front or clearance is also 0 .NOTE: For water heater clearances see instructionmanual that was included with the water : When these units are installed without return airducts, applicable installation codes may restrict theirinstallation to a single story Hydronic air handler as all Hydronic air handlerswill eventually leak.
