C.A.P. HUM-1 Quick Start Manual

CAP offers a full range of equipment for the growing enthusiasts. The HUM-1 is designed to
control the humidity level in your growing area. The unit can be used to either increase or
decrease the humidity level by activating a humidifier to add humidity or an exhaust fan /
dehumidifier to reduce the humidity level. Simple to use and reliable... the HUM-1.
The HUM-1 controls humidity by activating any
device that operates on 120 volt AC.
Two receptacles allow you to use the unit to
increase OR decrease humidity levels.
The HUM-1's indicator lights verifies the humidity
equipment is running.
The HUM-1 is backed by CAP's 3-year warranty.

CONNECTIONS & OPERATION
There are certain steps which should be taken to ensure a successful installation of your HUM-1.
1) Determine the desired location for the HUM-1. It should be at plant height and near a 120vac power
supply.
2) Mount the HUM-1 to a wall or other vertical surface. The ventilation slots must be oriented on the top and
bottom of the unit.
3) Depending on whether you will be using the unit for humidification OR de-humidification, the device you
will be using must be plugged into the correct receptacle.
Adjust the humistat to the desired highest level you want to maintain anywhere from 20-80% rH.
4)
* Verify the device you will be using to add or remove humidity has the capacity to raise or lower the
level adequately. If the device is not large enough, the HUM-1 will command the device to stay on
indefinitely.
Connect the power cord to a source of 120-vac power. * Maximum load = 15 amps.
5)
* NOTE: The HUM-1 requires "free air movement" to maintain humidity accuracy. The top and bottom of
the enclosure has ventilation slots to provide air-flow for the internal humistat. We recommend using an
oscillating fan or similar air movement device to provide fresh air for the plants, and the sensor.
