maintenance.
3. Make sure the electrical power source conforms to the requirement of the evaporative cooler(s) as well as
local codes. The power requirement for the PC-31 is 115v, 2.8 amps.

Starting and using the cooler
Cooler Setup and Operation
PC-31 is pre-assembled and ready to operate. Simply remove the packaging and then carefully remove the
unit from the box. Install Casters. Lock the 2 locking wheels before filling and turning on fan to keep the cooler
from moving from the air velocity.
NOTICE: the cooling pad will have a slight odor when it is new. This is normal. It will dissipate after a period
of time depending on the use time. Draining the tank often during the break-in period will help
speed this up. (See draining tank in section 5)
Filling Cooler or Connecting to Water Supply
Move the cooler to an area where it can be filled
Manual fill method
The cooler can be filled via the front fill door by hose or bucket. Using the water fill indicator to monitor water
level, simply depress the fill door and the spring lock will release and open it. To close, simply push it closed
and locked.
