AGronomic IQ Grow Room HVAC System AG204

1. Inspect and clean the drain pan(s)

2. Tighten electrical connections, if required

3. Check and tighten, if required, hose clamps and sensor mounts

4. Check that the P-trap is primed (filled with water). It is good practice to pour some water into the drain pan to ensure that the P-trap is primed and operational

5. Check the louvres and dampers (as applicable) for accumulation of dust and clean as required

6. Inspect the equipment’s cabinet for corrosion or other deterioration. If any damage is found, clean and repaint the affected surface with a rust-resistant primer

1. Warning: Hazardous chemicals! Cleaning agents can be highly acidic or alkaline. Handle all chemicals carefully and use appropriate personal protective equipment (PPE). Refer to the cleaning agent manufacturer's Materials Safety Data Sheet (MSDS) for safety and handling information. Failure to follow all safety instructions could result in serious injury or death

2. Warning: Hazardous pressures! Coils containing refrigerant under pressure must not be cleaned using a solution over 150 oF. Failure to follow these safety precautions could result in coil bursting, which could result in serious injury or death;

1. Ensure air filters are clean. Dirty air filters will negatively affect HVAC system performance and lifetime

2. Frequency of filters replacement will vary based on air quality, HVAC system usage, facility type, etc. Make sure to replace filters regularly

3. Replace with filters of equivalent size and rating – refer to HVAC system details (compartment stickers, etc.)

- Grow Room HVAC System Inspection!

1. Verify that all set-points are correctly programmed as specified by the facility operator;

Clean the fan wheel(s). Exercise caution not to disturb balance weights/clips, if any

Check dampers operation (linkage/actuator is not loose, damper opens/closes properly etc.)

Inspect electrical components, wiring and insulation

Rotate the fan wheel(s) and check for obstructions and rubbing

Check gasket condition on all doors to ensure an airtight seal

Check bolts on compressors, motor mounts, HVAC system bases and coils and tighten if required

Verify that the airflow around the remote condenser or dry cooler is unobstructed

AGronomic IQ equipment is intended to provide the ability to perform sensible cooling year-round. As such, systems are sold with appropriate glycol concentrations to prevent freezing/burst hazards

Though dry cooler itself is normally equipped with means to be drained properly/fully, it is recommended to have same means in place for entire system (dry cooler – piping – HVAC system etc.)

Have each local high point of the system equipped with means to bleed the air (air bleeding valve etc.)

Have each local low point of the system equipped with means to drain the fluid

CAUTION! Draining and re-filling the dry cooler must be performed by trained personnel, according to proper field practice and system layout. Improper draining or re-filling the system could lead to equipment damage, malfunction, premature tear and ware and may void equipment warranty

CAUTION! Ensuring that the dry cooler and associated system(s) equipped with proper means of draining, creating draining and re-filling procedures as well as determining whether draining is warranted to protect the equipment is outside of manufacturer’s scope and is a responsibility of installing contractor and local maintenance team;

Disconnect all electrical power to the equipment

Use a soft brush to remove loose debris from the coil

Mix a high-quality coil cleaning detergent with water according to the manufacturer's instructions

Clean coil according to detergent instructions

Thoroughly rinse both sides of the coil and the drain pan with, clean water

Straighten any coil fins that have been bent during the cleaning process

Confirm the drain line is clear

Replace all panels and parts and restore electrical power to the equipment
