However, service clearance must take precedence. A minimum of 24â€ in front of the unit for service clearance SIDE DRAIN PAN is required. Additional clearance on one side or top will be required for electrical wiring connections. Consult all appropriate regulatory codes prior to determining final clearances. When installing this unit in an area that may become wet (such as crawl spaces), elevate the unit with a sturdy, non-porous material. In installations that may lead to physical damage (i.e. a garage) it is advised to install a DPK1 DRAIN PLUG protective barrier to prevent such damage. Always install MAIN DRAIN PAN units such that a positive slope in condensate line (1/4â€ per foot) is allowed.

A filter will not fit on the internal filter rails in these applications. Side drain pan extension must be removed in the downflow and horizontal right applications for all models. Refer to Figure 6 and 7 for the location of the components referenced in the following steps. 1. Before inverting the air handler, remove blower access panel and coil access panel. The coil access panel and tubing panel may remain screwed together during this procedure. Remove and retain the seven (7) screws securing the coil access panel to the cabinet and the six (6) screws securing the blower access panel to the cabinet. 2. Slide the coil assembly out from the cabinet. Use the drain pan to pull the assembly from the cabinet. NOTE: Do not use manifolds, copper lines, or the flowrator to pull the coil assembly out. Failure to do so may result in braze joint damage and leaks. 3. Removal of the center support is required on units with 21â€ wide cabinet.

Failure to do so will result in panel damage. 6.4 Humid Environment Installations NOTE: Each service kit mentioned in this instruction is available through your local distributor. The kits are not supplied with the air handler and must be used to assist with condensation management in humid environment applications. The individual installation instructions provided with each kit must be followed. 6.4.1 ALL INSTALLATIONS â€“ HUMID ENVIRONMENTS Installations in areas where the return air environment sees humidity levels above 65% relative humidity, a High Humidity Kit (HHK) must be used. See Table 2 for Model and Kit assignment.

Examples include single-stage cooling and heat pump with single or two-stage electric heating. All these configurations can be applied with convenient connections to outdoor thermostat applications. The following sections are detailed: â€¢ Single-Stage Cooling â€¢ Heat Pump Each diagram details the connections between room thermostat and the air handlers, and the connections between the air handlers and the Condensing Unit (or Heat Pump) with optional connections to Outdoor Thermostats. For each configuration, refer to the explanation of the proper jumper(s) to remove for the corresponding blower speed that will result in the programmed fixed speed ECM motor. IMPORTANT: When matching the AMST air handlers to a single speed cooling or heat pump unit, remember to connect â€œYâ€ from the thermostat to the â€œY2â€ on the low voltage terminal board. Any equivalent thermostat can be used in place of the manufacturerâ€™s thermostat part number. 19 18 Wiring Diagrams HIGH VOLTAGE! DISCONNECT ALL POWER BEFORE SERVICING.
