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 combustion inducer fan for dirt buildup and lint

Check combustion air intake louvers and flue box/vent for accumulation of dirt and debris

Inspect and clean flue tubes and combustion chamber

Keep burner vestibule clean. Dirt and debris can result in poor combustion and lower efficiency

Rebel 003–015 units equipped with a ground fault interrupter?

Current sensing donut on the power wires to the compressor(s) present?

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.

The device works by opening the 120V controls circuit in a fault condition?

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