This appliance must be installed by a qualified service technician. Improper installation and/or operation can cause a potentially hazardous situation, which, if not avoided, could result in serious injury or death, and will void the warranty. The manufacturer cannot anticipate every circumstance that might involve a potential hazard. Each installation has its own specialized characteristics, requirements, and possible hazards. Therefore, all possible incidents are not included in these warnings.
D. When Servicing the Appliance Be sure to disconnect electrical power before opening appliance cabinet or performing service. Label all wires while performing service to ensure proper re-wiring of the appliance. Wiring errors can cause improper or dangerous operation. Failure to do so could result in an electrical shock, improper appliance operation, property damage, serious personal injury, or death.
H. Water Temperature Adjustment and Scalding This appliance can deliver scalding water. Be careful whenever using hot water to avoid scalding injury. Certain appliances such as dishwashers and automatic clothes washers may require increased water temperatures. By setting the thermostat on this heater to obtain the increased water temperature required by these appliances you may create the potential for scald injury. To protect against injury, install a mixing valve in the water system.
Part 2 - Before You Start Open the shipping crate of the appliance. UNCRATING THE APPLIANCE - Any claims for damage or shortage in shipment must be filed immediately against the transportation company by the consignee. A.
t Condensate Removal Pump (Part # 554200) t 2” Mesh Vent Screens (Part # 7850P-088) t UL353 Low Water Cut-Off Kit (Part # 7855P-315) NOTE: When using an optional system sensor, pipe insulation must be wrapped around it to improve temperature measurement accuracy and increase overall system efficiency. Part 3 - Prepare the Appliance Installation Remove all sides of the shipping crate to allow the appliance to be moved into its installation location.
All appliances eventually leak. It is recommended to install a catch pan beneath the appliance. This catch pan should be sized with a maximum depth of 2”, and a minimum diameter 2” greater than the diameter of the appliance. The catch pan should empty into an open drain line. This drain line should be 3/4” ID minimum, piped to an open drain. Failure to follow these instructions could result in property damage. Such damages ARE NOT covered by product warranty.
Vents must be properly supported. Appliance exhaust and intake connections are not designed to carry heavy weight. Vent support brackets must be within 1’ of the appliance and the balance at 4’ intervals. Appliance must be readily accessible for visual inspection for first 3’ from the appliance. Failure to properly support vents could result in property damage, severe personal injury, or death. The exhaust discharged by this appliance may be very hot.
