The Hitachi Air Purifier Model EP-PZ30J is designed to improve indoor air quality by removing various airborne contaminants. It is intended for home use only and should not be used for any other purpose. The device features a multi-stage filtration system and offers several operational modes to suit different air purification needs.
The core function of the EP-PZ30J is air purification, achieved through a combination of a pre-filter and a filter assembly. The pre-filter is designed to remove large-sized dust particles from the air. Following this, the air passes through the filter assembly, which includes an allergen-free, catechin deodorizing filter. This assembly consists of a white surface dust filter and a black surface deodorizing filter, working together to capture finer dust particles, allergens, and eliminate odors.
The purifier incorporates an odor sensor that detects air contamination, such as cigarette smoke or pet odors. Based on the sensor's readings, the device can automatically adjust its operation mode and airflow rate to effectively clean the air.
The EP-PZ30J offers flexible control options, allowing users to operate the unit either via a remote controller or directly through the control panel on the purifier itself.
Operation Modes: The device provides three primary auto modes:
Airflow Rate Selection: Users can manually select from three different airflow rates: Silent, Medium, and Max, to suit their preference or the level of air contamination.
Max Operation: For quick cleaning of room air, especially when there are many people smoking or a strong need for rapid purification, the "Max Operation" can be activated. This runs the purifier at maximum airflow for approximately 5 minutes before resuming the previous operation status.
Timer Function: An off-timer can be set for 2 hours, after which the operation will stop automatically.
Memory Function: When the purifier is stopped and restarted, it will resume operation with the settings that were active before shutdown, provided the operation lasted for approximately 5 seconds or longer. This memory function is available only when using the remote controller. Unplugging the power cord will clear the saved memory and restore factory settings.
Auto Detection: The unit's odor sensor detects the degree of air contamination and initiates automatic operation. Upon plugging in the power cord, the unit checks room air conditions for the first 3 minutes, during which the "Air Purify" indicator blinks. After this initial check, the purifier is ready to operate. If the power cord is plugged in under contaminated air conditions, the sensor sensitivity may be reduced.
Installation: The purifier should be installed in a well-ventilated place, away from heating appliances. It should not be placed on unstable pedestals or surfaces to prevent damage or failure from falling.
Regular cleaning and maintenance are crucial for the optimal performance and longevity of the Hitachi Air Purifier EP-PZ30J.
Purifier Body Cleaning: The purifier body and panel should be cleaned with a soft cloth moistened with water or a neutral detergent, then wrung dry. After cleaning, ensure no detergent residue remains. Volatile solvents, polishing powders, or alkaline cleaners should not be used, as they can cause deformation, discoloration, or damage to prints. The unit should also not be dried with a dryer or heater.
Pre-filter Cleaning: The pre-filter should be cleaned approximately once a month. This involves removing the panel and then the pre-filter. Dust can be removed using a vacuum cleaner. If dust cannot be removed, the pre-filter can be washed with water. After washing, it must be fully drained and dried in a well-ventilated place away from direct sunlight. A soft brush, such as an old toothbrush, can be used for washing. The pre-filter is a consumable part and should be replaced if damaged.
Filter Replacement: The filter assembly is a consumable part. The replacement interval is approximately 2 years, based on processing smoke from 5 cigarettes a day. However, the filter should be replaced earlier if its color resembles the dirtiness label attached to the purifier body, or if dirt or odor becomes harder to remove.
The filter may also need earlier replacement in specific scenarios, such as:
When replacing the filter, the unit must be stopped, and the power cord unplugged. The new filter should be taken out of its plastic bag before installation. The filter is not washable and cannot be reused; a new filter must be purchased for replacement. The filter contains synthetic resins, and its disposal should follow relevant local regulations.
