● Store units on a shelf or wooden pallet to protect against floor dampness.
● Cover the units to protect against dust and dirt.
● Maintain a near constant external temperature to prevent condensation from
forming inside these units and store in a well-ventilated, clean, dry room away
from vibration.
● Power should be supplied to the heater through a conduit entry with an
appropriate sealing gland.
