1. All tubing must be connected securely and routed to avoid kinks and traps.					326476-201 REV. B
2. Pressure tubing must always slope away from pressure switch to collector box connection as shown.
3. HORIZONTAL-LEFT installations require the collector box pressure tube to be relocated between the inducer housing and the blower shelf to					(lit-bottom)
prevent a trap. Refer to the Installation Instructions for further details.
