Daikin Packaged Rooftop System DPS007AHMY4DW-3

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

Clean Option E Coated Coils Surfaces

Quarterly cleaning is essential to extend the life of an Option E Coated Coil and is required to maintain warranty coverage

Coil cleaning shall be part of the unit's regularly scheduled maintenance procedures

Failure to clean an Option E Coated Coil will void the warranty and may result in reduced efficiency and durability in the environment

For routine quarterly cleaning, first clean the coil with the below approved coil cleaner

Coil cleaned with approved cleaner?

After cleaning the coils with the approved cleaning agent, use the approved chloride remover (under the Recommended Chloride Remover section) to remove soluble salts and revitalize the unit

Warning: This maintenance requires trained and experienced service technician

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

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

Perform maintenance of controls, gas valves, and other components in accordance with instructions in the manufacturer’s bulletins

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

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

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

Sharp edges are inherent to sheet metal parts, screws, clips, and similar items. May cause personal injury. Exercise caution when servicing equipment

Disconnect all electric power to the unit when servicing control panel components. Before servicing, always inspect units for multiple disconnects to ensure all power is removed from the control panel and its components

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.

The supply, condenser and exhaust fan motors are permanently lubricated and require no periodic lubrication.

Each unit as shipped is trim balanced to operate smoothly. To provide satisfactory operation after shipping and installation, use accepted industry guidelines for field balancing fans.

NOTE: Excessive vibration from any cause contributes to premature fan and motor bearing failure. Monitor overall vibration levels every six months of operation. An increase in levels is an indication of potential trouble.
