SAFETY CONSIDERATIONS WARNING: If the information in the supplied manual(s) is not followed exactly, a fire, explosion or exposure to hazardous materials may result, causing property damage, personal injury or loss of life. WARNING: Installation and service must be performed by a qualified installer or service agency, who must read and follow the supplied instructions before installing, servicing or removing this appliance.
Use proper wire size and branch circuit protection as required by National Electrical Code and state and local codes. The PVI electric hot water supply boiler data decal shows the volts, amps and phase of power to be connected.
1. Check the data decal on the boiler. Be sure the electrical and water supply is adequate for the installation. 2. Carefully remove all shipping supports and bracing. (Float type devices have shipping plugs blocking the float).
(See Table 1) Fill the hot water supply boiler with water. Open the relief valve to allow air in the tank to escape. Be sure all connections into the tank are tight as leaks at tank fittings or heating elements can cause damage.

(See Table 2). If amperage exceeds these limits, immediately turn off main manual disconnect and refer to Electric Boiler Trouble Shooting Guide). 7. Check magnetic contactors for noise. If noisy, i.e., buzzing or chattering, turnoff main power disconnect, disassemble contactor and blow out foreign particles.

5. The need to periodically check water level controls on the pressure vessel cannot be over emphasized. Most instances of major hot water supply boiler damage are the result of operating with low water or allowing lime and scale buildup.

Since low water cut-off devices are generally set by the original manufacturer, no attempt should be made to adjust these controls to alter the point of low water cut-off or point of pump cut-in or cut-out. If a low water device should become erratic in operation, or if it’s setting changes from previous established levels, check for reasons and correct, repair, or replace as required.
