Bard Q24A1 Installationair conditioner Instructions Manual

Manual 2100-522BPage 37 of 38FAN BLADE SETTING DIMENSIONSAny service work requiring removal or adjustment inthe fan and/or motor area will require that thedimensions in Table 5 be checked and blade adjusted inor out of the motor shaft accordingly.1 Maximum ESP (inches WC) shown is with 1" thick disposable filter (reduced by .2 for 2" filter).2 Rated CFM for ducted applications – required for maximum performance rating. To obtain full CFM on models Q36A1, Q42A1, Q48A1 andQ60A1 connect the pink jumper wire (provided) to terminal #G2 and #Y on the low voltage terminal block located in the circuit breaker box.3 Optional CFM – the unit is shipped from the factory set to operate at the optional CFM level shown. This provides lower operating soundlevels for non-ducted, free discharge applications. This reduces system capacity performance by approximately 2% at the same energyefficiency.4 Continuous fan CFM is the total air being circulated during continuous fan mode.5 Model Q24A1 – when operating on 2nd stage heating the indoor air will increase to 1000 CFM.R-410AREFRIGERANT CHARGEThis unit was charged at the factory with the quantity ofrefrigerant listed on the serial plate. AHRI capacity andefficiency ratings were determined by testing with thisrefrigerant charge quantity.The following pressure tables show nominal pressuresfor the units. Since many installation specific situationscan affect the pressure readings, this information shouldonly be used by certified technicians as a guide forevaluating proper system performance. They shall notbe used to adjust charge. If charge is in doubt, reclaim,evacuate and recharge the unit to the serial plate charge.FIGURE 27FAN BLADE SETTINGTABLE 5FAN BLADE DIMENSIONSLEDOMANOISNEMID)SEHCNI(llA1A**QsledoM057.NOTE: These units are equipped with a variable speed (ECM) indoor motor that automatically adjust itself tomaintain approximately the same rate of indoor airflow in both heating and cooling, dry and wet coilconditions and at both 230/208 or 460 volts.TABLE 6INDOOR BLOWER PERFORMANCEledoM PSEdetaR1PSE.xaM2MFCdetaR3 lanoitpOMFC4 suounitnoCMFC@MFCxaM PSE.1A42Q 5 01. 5.0 008 008 0071A03Q 51. 8.0 0001 0001 0191A63Q 51. 8.0 0021 0001 0001 57111A24Q 51. 8.0 0021 0001 0001 57111A84Q 51. 8.0 0041 0011 0011 57111A06Q 02. 5.0 0551 0521 0521 0041
