Cooler Installation

Installing Casters

Note: The installation kit includes (2) swivel casters with brake, (2)

swivel casters without brake, (16) tinnerman nuts and (16) 1/4-20

x 1/2 screws.

• Place the unit on its side. Place the tinnerman nuts on the caster

bracket on the bottom pan as shown in ﬁ gure 1.

• Attach the casters to the brackets with the screws provided.

Operation

Settings

• Pump setting. The rotary switch has 6 settings. The “Pump”

setting will operate the pump without the blower. For best results

turn the switch to “Pump” for a few minutes to wet the pads before

operating the fan.

• High and low cool settings. The “High Cool” and “Low Cool” set-

tings operate both the pump and the blower. Turn the unit to “Low

Cool” when possible. This lower speed allows the air to stay longer

in the wet pads and therefore increases it’s cooling efﬁ ciency.

• High and low vent settings. The “High Vent” and “Low Vent”

settings operate the blower without the pump. This is useful on

cool nights or at times when just a fan is desired.

Exhaust Air

If the unit is used in an enclosed area, open windows or doors to ensure

adequate exhaust. Without an outlet to exhaust the air, humidity will

build up in the enclosed space and the unit will not cool adequately.

Connecting Water

• Install drain assembly. Place the

nipple through the hole in the pan,

with the rubber washer between the

pan and the head of the drain nipple

(Fig. 2). Thread nut onto nipple and

draw up tight against bottom of pan.

Thread the drain cap to the nipple and

tighten water tight.

• Install ﬂ oat valve. Refer to ﬁ gure 3. Install the valve in the pro-

vided hole in the corner post using the provided washer and nut.

Install the included garden hose adapter to the ﬂ oat as shown if

attaching a garden hose to the unit. A 1/4 inch water line may also

be used to supply a continuous amount of water to the unit.

• Fill pan with water. You may ﬁ ll the pan manually for up to 3

hours of cooling. For automatic ﬁ lling you may attach a garden

hose to the garden hose adapter or a 1/4 inch water line to the ﬂ oat

valve.

Note: Do Not Overﬁ ll. Fill water to a maximum height of 2 1/2

inches (approximately 1 inch from the top of the bottom pan). If

using a garden hose, the ﬂ oat will need to be adjusted to maintain

this water level. This can be accomplished by bending the ﬂ oat

rod.
