If the door height allows, the unit can be slid sideways through the door. If the unit can not be slid through the door, then the unit will have to be put on a cart and tipped down to roll through the door. It is recommended that an appliance cart by used with a strap to hold the unit on the ...

FIGURE 6 DUCTED APPLICATION FIGURE 5 INSTALLATION WITH DUCT FREE PLENUM ...

DUCT WORK Any heat pump is more critical of proper operating charge and an adequate duct system than a straight air conditioning unit. All duct work must be properly sized for the design airflow requirement of the equipment. Air Conditioning Contractors of America (ACCA) is an excellent guide to proper sizing. All duct work or portions thereof not in the conditioned space should be properly insulated in order to both conse ...

FRESH AIR INTAKE This unit is equipped with a fresh air damper assembly. The damper blade is locked in the closed position when the unit is shipped from the factory. To allow the damper to operate remove the two plastic locking pins, one on each end of the blade. This will allow for maximum fresh airflow. The damper blade will now open when the indoor blower is operating. If less than maximum fresh airflow is required, re ...

INSTALLATION MOUNTING THE UNIT When installing a Q-TEC unit near an interior wall on the left side, a minimum of 8 inches is required; 12 inches is preferred. When installing a Q-TEC unit near an interior wall on the right side, a minimum of 18 inches is required as additional space is required to connect the side drain. If the rear condensate drain kit QCDS48 is used the minimum can be reduced to 8 inches. This clearance is ...

OPTIONAL CLIMATE CONTROLS SEQUENCE OF OPERATION The standard Climate Control Option X is a remote thermostat connection terminal block. See Figure 17 or Figure 18 for wiring diagram. Compatible thermostats are listed in Table 4. The Climate Control Option E is an electronic, programmable thermostat with humidistat. The subbase of the thermostat is factory wired to the front panel of the unit. See Figure 19 for wiring diag ...

If the unit is running in heat pump mode and the humidistat calls for dehumidification, the dehumidification mode takes precedence over the heat pump heating mode. The unit will not return to the heating mode until 2nd stage heating is called for. The Climate Control Option I is an electronic, programmable thermostat with humidistat and a CO2 controller. The subbase of the thermostat and CO2 controller are factory wired to ...
