Condensate Drain - York YAP026 Installation Manual

AFFINITY SERIES OUTDOOR PACKAGED HEAT PUMP INSTALLATION MANUAL
General Installation Information cont.
Contaminated Water
In applications where the water quality cannot be held to
prescribed limits, the use of a secondary or intermediate
heat exchanger is recommended to separate the unit from
the contaminated water. The table below outlines the
water quality guidelines for unit heat exchangers. If these
conditions are exceeded, a secondary heat exchanger is
required. Failure to supply a secondary heat exchanger
where needed will result in a warranty exclusion for primary
heat exchanger corrosion or failure.
Low Water Coil Limit
Set the freeze sensing switch SW2-1 on the Aurora Base
Control (ABC) printed circuit board for applications using
a closed loop antifreeze solution to "LOOP" (15°F). On
applications using an open loop/ground water system (or
closed loop no antifreeze), set this dip switch to "WELL"
(30°F), the factory default setting. (Refer to the DIP Switch
Settings table in the Aurora Control section.)

Condensate Drain

To facilitate complete condensate removal, the outdoor
package unit should be mounted level or slightly pitched
towards drain. A PVC tube and coupler are provided with
the unit. The coupler and tube need to be field installed to
the drain pan using PVC primer and glue. An external trap
is required (see figure 3) otherwise condensate will not
drain during unit operation. If a vent is necessary, an open
stand pipe may be applied to a tee in the field installed
condensate piping. The vent must be installed on the outlet
side of the condensate trap as shown in figure 3 or proper
drainage will not occur. Mastic tape is provided to seal
around the condensate opening.
Note: Do not operate the heat pump without a trap.
