3. Product Selection & Capacity Sizing Questions

What’s the difference between DH-70, DH-145 and DH-245 models?
DH-70: 70 Pints/day, covers up to 1,000 sq. ft, 410W, ideal for basements, closets, bedrooms, small storage rooms
DH-145: 155 Pints/day, covers up to 6,000 sq. ft, 1050W, suitable for offices, archives, small warehouses, gyms and swimming pools
DH-245: 260 Pints/day, covers up to 8,500 sq. ft, 1300W, heavy-duty for large warehouses, industrial workshops, museums and libraries

How to calculate the right pint size dehumidifier for my space?
Measure your total square footage first. Severe damp spaces (coastal basements, crawl spaces, swimming pools) need to upgrade one size up for stable humidity control. Our team can offer free sizing consultation if you send room size and humidity condition.

Can these industrial units work in crawl spaces?
All three models are equipped with built-in condensate pump supporting 16.5ft upward drainage, perfect for crawl spaces without floor drains. The auto defrost system keeps stable performance in low-temperature underground environments.

Are Prikod dehumidifiers IP24 rated?
Yes, the full metal rust-proof body meets IP24 dust & moisture resistance standard, suitable for damp construction sites, warehouses and humid workshop environments.

Can I use the machine in RV, camper or small mobile storage?
DH-70 compact commercial model with lockable casters and ergonomic handles is portable enough for RV, trailer and temporary storage use. DH-145 / DH-245 are designed for fixed large commercial spaces.

Do the units work for production workshops and battery factories?
DH-145 and DH-245 heavy-duty models are widely applied in SMT electronic workshops, battery production lines and dried fruit warehouses to stabilize low humidity and prevent product moisture damage.

4. Daily Operation, Drainage & Function Guide

What is the ideal indoor humidity setting?
The optimal humidity range for living & storage is 40%–60% RH. Set 45%–50% for daily comfort; set 40%–45% for warehouse, archive and production storage to fully prevent mold and corrosion.

Can I run the dehumidifier 24 hours nonstop?
All Prikod industrial dehumidifiers support continuous 24-hour long-term operation. The auto-shutoff protection will activate when the water tank is full to avoid overflow.

Two drainage modes: gravity drain vs built-in pump drain, how to choose?
Gravity drain: For spaces with floor drains lower than the unit, simple hose connection for natural water outflow
Built-in pump drain: For basements, crawl spaces, sinks higher than the machine, the pump lifts water up to 16.5ft for long-distance discharge, no manual tank emptying required.

Does the unit have automatic defrost function?
Yes, auto defrost is pre-installed on all DH series. When coil icing occurs under low temperature, the machine will automatically melt frost without stopping dehumidification.

Is there a 24-hour programmable timer?
All models support 24-hour timing function, you can set scheduled startup and shutdown to save power consumption for unattended spaces.

How noisy are the commercial dehumidifiers?
DH-70 runs at lower decibel for bedroom and office use; DH-145 and DH-245 deliver stronger airflow with louder fan noise at maximum speed, more suitable for warehouse and industrial scenarios instead of quiet sleeping rooms.

Will the dehumidifier eliminate mold and musty odors?
Yes. Mold and mildew only grow above 60% humidity. By steadily lowering indoor moisture, the machine stops mold reproduction and removes damp, stale basement odors fundamentally.

Do I need to empty the water tank regularly?
If you connect continuous pump/gravity drainage hose, tank emptying is not required. Without drainage setup, you need to empty the tank when full; the machine will auto shut down to prevent water leakage.

Can I move the dehumidifier easily between rooms?
Lockable universal casters and heavy-duty top handles are equipped on all units, you can push and relocate the machine freely on flat ground. Adjustable feet stabilize the unit on uneven concrete floors.

What power supply does the unit require?
All DH series operate on standard 110V–120V / 60Hz US household power. Do not use with 220V outlets unless you have a step‑down transformer. A dedicated 15A circuit is recommended for DH‑145 and DH‑245 to avoid tripping.

5. Maintenance, Cleaning & Troubleshooting

How often should I clean the air filter?
Clean the mesh filter every 2–4 weeks under normal use; clean once per week in dusty workshops or construction sites. Rinse with clean water and air-dry completely before reinstallation. Clogged filters will drastically reduce dehumidifying efficiency.

What routine maintenance does the industrial unit need?
Weekly filter cleaning
Monthly check drainage hose for blockages or water leakage
Every 6 months wipe evaporator coil surface to remove dust buildup
Store the machine upright in dry ventilation if long-term idle

How much clearance space should I leave around the unit?
Keep at least 20 inches (50 cm) of clearance on the air inlet side and 12 inches (30 cm) on the outlet side. Insufficient clearance reduces airflow, lowers efficiency, and may trigger overheating protection.

Why is my dehumidifier running but humidity won’t drop?
Common reasons:
The model capacity is too small for your space
Windows/doors stay open, constant outdoor humid air flows in
Air filter is fully blocked, airflow is restricted
Severe air leakage around walls or basement foundation

Why does the unit freeze up during operation?
Low ambient temperature triggers coil frosting. The built-in auto defrost system will automatically melt ice; if frost persists for hours, check if the filter is clogged or the fan speed is too low.

Machine shuts down unexpectedly, what to check first?
Water tank is full and triggers auto shutoff
Power cord loose or circuit breaker tripped
Unit placed on uneven ground, safety tilt protection activated
Overheating protection due to blocked air inlet/outlet

Water leaks from the dehumidifier body
Drain hose connection loose or cracked
Drain pipe blocked by dirt and debris
Water tank not fully inserted into position
Internal condensate pump malfunction (contact support for repair)

Unusual loud vibration noise during operation
Unit placed on uneven ground, adjust support feet to level
Foreign objects stuck inside fan or air outlet
Filter improperly installed, causing airflow collision

Can I disassemble the machine myself for repair?
Unauthorized disassembly will void the 2-year warranty. If troubleshooting steps cannot solve the fault, stop running the unit and contact our technical support team for professional guidance.

My unit won't restart after a power outage – what should I do?
Most models have an auto‑restart function, but if it does not resume, manually press the power button. Check if the circuit breaker reset. For prolonged outages, unplug the unit for 5 minutes, then plug back in – this clears the control board memory.
