Equipping a system

• always use a suction accumulator.
• size condensing unit for slightly less than the evaporator at a normal ambient (or slightly above).
• equip a condensing unit with fan cycling or head pressure control to maintain a minimum head pressure.
• if installing the condensing unit more than 25 feet from the unit a coalescing oil filter is recommended for long system life. If one is not used, ensure that proper amounts of oil are added at time of commissioning system. Careful attention to oil return will lead to a reliable system.
• When selecting an evaporator and humidity will be other than 55-60% relative humidity a different set of parameters will be required. Please contact the factory.
• For systems with duct runs please take into account thermal losses on the duct runs.
