York Rooftop Unit Y13FC04C1LABAB

CAUTION: Prior to any of the following maintenance procedures, shut off all power to the unit. Failure to do so could cause personal injury. Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.

MOTORS: Outdoor fan motors are permanently lubricated and require no maintenance. Lubrication, if desired, is to be performed by a qualified service agency. Ventor motors are factory lubricated for an estimated 10-year life.

All wires labeled prior to disconnection?

Proper operation verified after servicing?

Sign off on the maintenance procedure

CAUTION: This procedure requires trained personnel with PPE!

Is the unit equipped with power exhaust fans or a return air fan?

If yes, check belt tension and adjust as necessary

Loosen the four bolts holding the motor base to the channels

Adjust the belt by turning nuts 'A'

Enter the deflection distance from the normal position

Use the recommended deflection force per the Belt Adjustment Table

Tension new belts at the maximum deflection force recommended

Check the belt tension at least two times during the first 24 hours of operation

WARNING: Perform all maintenance operations on the blower motor with power disconnected from the unit. Do not attempt to lubricate bearings with the unit in operation.

Power disconnected from the unit?

If desired, every three years remove both pipe plugs at each end shell and clean out any hardened grease or foreign matter.

Both pipe plugs removed and cleaned?

Replace one plug on each end with a clean grease fitting.

One plug on each end replaced with a clean grease fitting?

Using a low pressure grease gun, pump grease (Chevron SRI-2 or equivalent) into the bearing cavity until new grease shows at the open port. Do not over-lubricate.

Grease pumped into the bearing cavity until new grease shows at the open port?

CAUTION: Before making any blower speed changes review the installation for any installation errors, leaks or undesirable systems effects that can result in loss of air flow. Even small changes in blower speed can result in substantial changes in static pressure and BHP.

BHP or AMP draw of the blower motor will increase by the cube ratio of the blower speed. Static pressure will increase by the square ratio of the blower speed.

Tables 24 and 25 are for reference only. All blower speed changes must be made by qualified personnel with strict adherence to the fan laws.

Measured CFM based on Figures 58 and 59

CAUTION: Prior to any of the following maintenance procedures, shut off all power to the unit. Failure to do so could cause personal injury.
