Section A1- Outdoor/Return Air Section
➩
Primary Codes that pertain: 19, 20, 21, 22, 23 Additional Codes that pertain: 06, 09, 12, 14, 15, 16, 17, 49
Codes 19 and 20 determine the base section. Code 19 is the Return Air Plenum, and determines if the unit has back (a.k.a. horizontal) return air or bottom return air. The plenum is required for any outdoor air application with an economizer (Code 20= BE, BY, DE, DY, EE, EY, FE, FY, GE or GY). The only case in which a plenum is not required is when a 100% outdoor air damper and hood are ordered (C20= AE, AY).
Codes 21, 22, 23 determine the return air fan, motor and drives. These codes only pertain to units with a 0-100% economizer (C20= DE, DY, EE, EY, FE, FY, GE or GY). The fan section parts, the fans, and the motors are listed in this section. The drive components (fan sheave, motor sheave, belt, and fan bushing) are not listed as
they are unique to the unit. If a drive component is required you may use the number from the part and cross reference it with the Drive Components Cross Reference form number: 571006, or contact Daikin McQuay Parts to ensure that the needed part(s) are correctly identified. The motors range anywhere from
1- 10 horsepower, and the fan wheels range from 15" FC to 40" AF.
Code 06 determines the panels used in final cabinet assembly (return air units only).
Notes
Code 09, the voltage, is part of the motor part number identification.
Code 12, the control system comes into play when an economizer is present. The economizer comes with an actuator motor on any MicroTech unit (C12= 1M, 2M, 4M, or 5M [original MicroTech] or L*, B*, E* or S* [MicroTech II or MicroTech III]), but may not have a motor if the unit has controls by others (C12= YC or YM).
Code 14 determines if the return fan has an inverter, or variable frequency drive. If code 14 equals 1-9 (or X for units built prior to 2000) , then the unit has inverters, and cannot, therefore have wheels with variable inlet vanes (which haven't been used on production units since 2003).
Code 15, determines if Variable Inlet Vanes (VIV) are present (these haven't been used on production units since
2003). If code 15= 2, they are present on the return fan. VIV is only available on units with 0- 30% economizers (C20= BE, BY).
Code 16 determines the smoke detector which is located in the return air cabinet. C16= 1 or 3 if a smoke detector (SD2) is present.
Code 17 determines the Enthalpy Control. If C17= Y* and the unit has an economizer there is a mechanical enthalpy control (OAE). If C17= C*, there is a differential enthalpy control (OAE + RAE).
Code 49 determines if the return air cabinet has a light, switch and receptacle (C49= B), fan belt guards (C49= D) or both (C49= F).
