Carrier 58MVP - Prime Condensate Trap with Water; Purge Gas Lines

1. Remove main furnace door and blower access panel.
2. Locate setup switches on furnace control. (See Fig. 32.)
3. See Table 9 for setup switch description. (See Fig. 31 and 51.)
4. Replace main furnace door and blower access panel.
NOTE: If a bypass humidifier is used, setup switch SW1-3 (Low
HEAT Rise Adjust) should be in ON position. This compensates
for the increased temperature in return air resulting from bypass.
NOTE: If modulating dampers are used, blower motor automati-
cally compensates for modulating dampers.
Step 3—Prime Condensate Trap With Water
Condensate trap must be PRIMED or proper draining may not
occur. The condensate trap has 2 internal chambers which can
ONLY be primed by pouring water into the inducer drain side
of condensate trap. Failure to follow this caution will result in
intermittent unit operation or performance satisfaction.
1. Remove upper inducer housing drain connection cap. (See
Fig. 52.)
2. Connect field-supplied 1/2-in. ID tube to upper inducer
housing drain connection.
3. Insert field-supplied funnel into tube.
4. Pour 1 quart of water into funnel/tube. Water should run
through inducer housing, overfill condensate trap, and flow
into open field drain. (See Fig. 53.)
5. Remove funnel and tube from inducer housing and replace
drain connection cap and clamp.
Step 4—Purge Gas Lines
If not previously done, purge the lines after all connections have
been made and check for leaks.
