Overcurrent Protection, Blower Speed | Acnodes Q5RF SERIES guide

Overcurrent Protection

Overcurrent protection must be provided at the branch circuit distribution panel and sized as shown on the unit rating label and according to applicable local codes. Generally, the best fuse or breaker for any heat pump is the smallest size that will permit the equipment to run under normal usage and provide maximum equipment protection. Properly sized fuses and breakers also prevent nuisance trips during unit startup.

If a fuse blows or a breaker trips, always determine the reason. Do not arbitrarily install a larger fuse or breaker and do not, in any case, exceed the maximum size listed on the data label of the unit.

2-Speed Outdoor Fan Motor

(Select Models)

If the unit utilizes a 2-speed condenser fan motor, this motor will operate on low speed when in low cooling/heating, and on high speed when in high cooling/heating.

Blower Speed

For optimum system performance and comfort, it may be necessary to change the factory speed setting.SeeTable 4 (page 20) for factory settings. NOTE:Q5RF models have High Efﬁciency Motors with 5 speed taps.

WARNING:

To avoid electric shock, personal injury,or death,turn off the electric poweratthedisconnectorthemain service panel before making any electrical connections.

1.Disconnect all electrical power to the unit and remove the service panel.

CAUTION:

Labelallwirespriortodisconnection when servicing controls. Wiring errors can cause improper and dangerous operation.Verify proper operation after servicing.

2.Locate the orange, black and red wires terminated to the blower motor. The orange wire controls the low speed cooling and heating operations, the black wire controls high speed cooling and heating operations and the red wire controls the electric heating operation.

CAUTION:

To avoid personal injury or property damage, make certain that the motor leads cannot come into contact with any metal components of the unit.

3.Verify the required speed from the airﬂow data found inTable 4.Place appropriate wire on the appropriate motor speed tap for the required airﬂ ow.

4.Check all factory wiring per the unit wiring diagram and inspect the factory wiring connections to be sure none loosened during shipping or installation.

Ambient Sensor Mounting

For optimum performance of the heat pump system, the ambient sensor (Figure 9) must be mounted on the outside of the unit.

1.	Remove the mounting bracket and all
	hardware	included in	the packet .
2.	R e m ove	s t a r bu s h i n g	f r o m 7 / 8 ”
	hole in corner panel of the unit.
3.	Route the ambient sensor through the 7/8”
	hole in the corner panel of the unit, and then
	through the 7/8” hole in the mounting bracket.

4. R o u t e t h e s e n s o r	t h r o u g h t h e
star bushing. Use the	star	bushing to
secure the mounting bracket		to the unit.

5.Secure the ambient sensor inside the plastic clip and secure it to the mounting bracket with the screw and nut provided.

6.Install one spacer next between the plastic clip and mounting bracket.

7.Bend the mounting bracket into position. Install the mounting bracket to the unit using the screw in the corner panel.
