Daikin Packaged Rooftop System DPS006AHCE4DW-4

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

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.

WARNING: Prior to cleaning the unit, turn off and lock out the main power switch to the unit and open all access panels

The following cleaning procedures are recommended as part of the routine maintenance activities for Option E Coated Coils. Documented routine cleaning of Option E Coated Coils is required to maintain warranty coverage.

1. Remove Surface Loaded Fibers: Surface loaded fibers or dirt should be removed prior to water rinse to prevent further restriction of airflow.

2. If unable to back wash the side of the coil opposite that of the coils entering air side, then surface loaded fibers or dirt should be removed with a vacuum cleaner. If a vacuum cleaner is not available, a soft non-metallic bristle brush may be used. In either case, the tool should be applied in the direction of the fins. Coil surfaces can be easily damaged (fin edges bent over) if the tool is applied across the fins.

NOTE: Use of a water stream, such as a garden hose, against a surface loaded coil will drive the fibers and dirt into the coil. This will make cleaning efforts more difficult. Surface loaded fibers must be completely removed prior to using low velocity clean water rinse.

3. Periodic Clean Water Rinse: A monthly clean water rinse is recommended for coils that are applied in coastal or industrial environments to help to remove chlorides, dirt and debris. An elevated water temperature (not to exceed 130°F) will reduce surface tension, increasing the ability to remove chlorides and dirt. Pressure washer PSI must not exceed 900 psig and the nozzle should remain at least 1 foot from the coil to avoid damaging fin edges.

Warning: This service requires trained personnel with PPE!

Is the current sensing donut on the power wires to the compressor(s) functional?

The device is intended for personal safety by continuously monitoring the balance between the three phase power and the neutral conductor.

It is not intended to provide overcurrent or short circuit protection to the equipment.

Is the 120V controls circuit in a fault condition?

Is there an open condition on the ground fault interrupter?

An open condition on the ground fault interrupter indicates the compressor has been grounded.

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
