Duct Work, Filters, Supply Duct Connections

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 air flow 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 conserve energy and prevent condensation or moisture damage. When duct runs through unheated spaces, it should be insulated with a minimum of one inch of insulation. Use insulation with a vapor barrier on the outside of the insulation. Flexible joints should be used to connect the duct work to the equipment in order to keep the noise transmission to a minimum.

The QTEC series unit has provision to attach a supply air duct to the top of the unit. Duct connection size is 12 inches x 20 inches. The duct work is field supplied and must be attached in a manner to allow for ease of removal when it becomes necessary to slide the unit out from the wall for service. See Figure 7 for suggested attachment method.

NOTE: Unit cabinet, supply air duct and free blow plenum are approved for “0” clearance to combustible material.

When used with a ducted supply, a QCX Cabinet Extension can be used to conceal the duct work above the unit to the ceiling. This extends 20” above the unit for a total height above the floor of 10’-7/8”. See Optional Accessories, Page 18 for the correct Cabinet Extension model number. The unit is equipped with a variable speed indoor blower motor which increases in speed with an increase in duct static pressure. The unit will therefore deliver proper rated air flow up to the Maximum ESP shown in Table 5. However, for quiet operation of the air system, the duct static should be kept as low as practical, within the guidelines of good duct design.

FILTERS

Two 1 inch throw away filters are supplied with each unit. The filters fit into a fixed rack.

The filters are serviced from the inside of the building . To gain access to the filters release the latch on the circuit breaker door and one 1/4 turn fastener near the bottom of the door. This door is hinged on the left so it will swing open.

The internal filter brackets are adjustable to accommodate 2 inch filters. The tabs for the 1 inch filters must be bent down to allow the 2 inch filters to slide in place.
