UNITS WITHOUT ELECTRIC HEATING ELEMENTS
SINGLE POINT GROUNDING (OPTION 2)
1. DO NOT connect an independent ground rod to the GARN® unit:
4. If a pump connected directly to the GARN® unit is wired to a different panel, then the pump and blower motor must be electrically isolated:
2. Check to ensure that the unit is set on foam:
Isolate the blower motor with a blower motor isolation kit: Part #P-0125 which can be found on www.garnparts.com. Installation instructions for the isolation kit can be found on p.85. A pump is di-electrically isolated if there is a means that breaks the metal-to-metal contact between the pump housing itself and the GARN® unit. Examples of di-electric isolation include: di- electric unions, any length of PEX, or isolation valve flanges attached directly to the pump (such as Grundfos di-electric isolation valves).
3. Check to ensure that the blower motor and ANY pump that IS NOT dielectrically isolated from the GARN® unit is to be wired to the same electrical panel:
