Select filter size based on cabinet size

Sign off on the filter replacement

Prepare for storage control compartment

Is the electronic control equipment in the unit stored in a 5% to 95% RH (non-condensing) environment?

It may be necessary to put a heat source (light bulb) in the main control panel to prevent the accumulation of atmospheric condensate within the panel. The location and wattage of the heat source is dependent on local environmental conditions

Is the heat source adequate for current conditions?

Sign off on the rooftop system maintenance

Warning: This maintenance requires trained and experienced service technician

Warning: Fuel pressure settings and control settings should be made only by persons thoroughly experienced with the burner and control system

Warning: Always replace covers on burner controls and boxes as the electrical contacts are sensitive to dust and dirt

Warning: Installation and maintenance must be performed only by qualified personnel who are experienced with this type of equipment and familiar with local codes and regulations

Warning: Gas or Hot Water Piping: A qualified Architect or Systems HVAC Design Engineer familiar with piping design, local codes and regulations, must provide piping design

Danger: Moving machinery and electrical power hazards. May cause severe personal injury or death. Disconnect and lock off all power before servicing equipment

Warning: Sharp edges are inherent to sheet metal parts, screws, clips, and similar items. May cause personal injury

Warning: Disconnect all electric power to the unit when servicing control panel components

Danger: Hazardous voltage. May cause severe injury or death. Disconnect electric power before servicing equipment

The Rebel unit has many configurable options that can affect the refrigerant charge. Actual unit charge is given on the unit's data plate found on the inside of the control panel.

The Rebel unit uses electronic expansion valves that maintain peak efficiency. Liquid sub-cooling and suction super heat float and should not be used as an indication that charge needs to be added or removed from the system.

If a leak is suspected, the full charge should be removed and weighed. Weight should be compared against the unit nameplate data. Unit should be recharged with the amount given on the unit nameplate.

POE and PVE oil is hygroscopic and does absorb moisture when exposed to atmosphere. Steps should be taken to minimize exposure time to atmosphere during any maintenance where the sealed system is to be opened.

Rebel 003-015 refrigerant systems use only Polyvinylether (PVE) oil. Rebel 016-028 refrigerant systems use only Polyester (POE) oil.

NOTICE: Do not use POE oil in DPS 003-015 refrigerant systems and do not use PVE oil in DPS 016-028 refrigerant systems.

The entire system must be evacuated using a suitable vacuum pump.

The quality of vacuum is measured using a suitable micron gauge that has been calibrated.

Check all moving parts for wear every six months

The Rebel exhaust fans are direct drive variable speed fan/motor combination, which do not have belts or pulleys to maintain

The bearings are permanently sealed and do not require periodic greasing. The Rebel 3-15 ton units have similar supply fans.

The Rebel 16-28 tons supply fans have a direct drive motor

These larger motors are not permanently sealed and will require greasing every 9000 hours
