CONDENSATE DRAIN - COOLING
The Dynapack unit and wall sleeve each have there own drain. The unit drain
is for the condensate developed by the evaporator coil. It needs to be trapped
and routed to the building drain system. Use 3/4" pvc pipe and fittings (field
supplied). The wall sleeve is equipped with a drain pan that collects rain water
entering the wall sleeve and the unit condenser coil area. At the time of
installation of the wall sleeve, this drain can be directed directly outside or
turned inside and routed to the building drain system. If the wall sleeve
drain is routed to the building sewer system then it must be trapped to
prevent sewer gasses from escaping. The top of the sewer trap must be no
higher than 18 inches above the bottom of the furnace. See Figure 18.
CONDENSATE DRAIN - FURNACE
The high efficiency furnace in this unit will produce condensate when
operating. In addition, a trap is needed in order to overcome the negative
pressure produced by the combustion inducer blower.
1. With the gas valve and outdoor section access panels removed, connect
the drain trap to the internal drain hoses using the 90 degree barb
fittings provided.
2. Install the ¾ x ¾ x 5/8 tee fitting in the air conditioner drain at the
level of the combustion condensate trap.
3. Complete the furnace drain line by installing a barb fitting into the
drain trap hose.
4. Install a 5/8 vinyl hose between the barb sitting and the tee fitting
installed in the air conditioner drain line. See Figure 5. The furnace
condensate line will self-prime on startup.
Note: The furnace drain and air conditioner condensate drain are open to the
atmosphere which gives pressure equalization on the sewer trap preventing
"double trapping."
FLUE GAS EXHAUST TUBE INSTALLATION (H SERIES MODELS)
All H Series DynaPack units are shipped with the Flue Gas Exhaust Tube
disconnected. Locate the Flue Gas Exhaust Tube inside the unit cabinet and
the clamps and couplers in the accessory bag. Connect the Flue Gas Exhaust
Tube using the rubber coupler as shown in the photo below.
