H Standard installation practice is to mount the motor starter or fused DRAIN NIPPLE disconnect box adjacent to the air handler and enclose the power FAN OFF wiring to the motor in flexible conduit. The sheet metal housing of the disconnect switch or motor starter DIFFERENTIAL is not airtight (...
This is designed to provide sufficient space to run electrical and communication wiring as well as HVAC ductwork. Sometimes small pipes are designed to run in a wall system, whereas larger pipes may need deeper walls or even chase walls to accommodate them. Fan systems that exhaust air from ...
