External Water Tank Feature:

This unit is equipped with a secondary “External

Water Tank” which sits on a support tray and easily

attaches to the rear side of the unit by means of a

quick connect fitting. The male quick connect is

attached to the water tank, the female quick connect

is attached to the back of the main unit. We

recommend the external water tank be connected to

the main unit at all times during both air conditioning

and dehumidifying modes. These water tanks allow

for the storage of excess accumulated condensed

water produced during cooling/dehumidifying

operation.

It is possible to operate the unit utilizing the

“Internal” (primary) water tank only. (However,

running time/operation maybe reduced during

high humidity conditions) If the external water

tank is not connected to the main unit, (excess)

condensed water is automatically directed into

the internal water tank. When the external water

tank is utilized, (excess) condensed water is

directed first into the external tank. When the

external tank is full the water will then backflow

into the internal tank.

Cooling Operation:

During air conditioning mode condensed water

accumulates in a pre-cooler drip tray located

underneath the evaporator (cooling) coil. When the

water level reaches a predetermined level, the water

flow is directed into a small (well) holding tank

located at the bottom of the unit. When the water

level in the well reaches a pre-determined level, a

water pump is automatically activated that pumps

the water upto the condenser coil and is

subsequently cascaded across the fins of the

condenser coil.

This showering action is very efficient in terms of;

1) Keeping the condenser coil cool during operation.

2) Provides maximum cooling ef

ficiency

As the water cascades across the heated fins of the

condenser coil, it is evaporated.

This process

minimizes accumulated water from being stored in

both holding tanks, which results in longer running

times and less frequent emptying of the water tanks.

This process is continuous during air conditioning

mode only

NOTE: During high humidity conditions,

if the rate of water being condensed exceeds the

rate of water being evaporated, a solenoid valve

automatically opens allowing for excess water to be

directed into the holding tanks.

When the water level in the well returns to normal,

the solenoid valve automatically closes and the

water is again directed into well and the water pump

continues normal operation. When the water level

inside the external tank reaches it’s maximum level,

the water will then backflow into the (primary)

internal water tank. The water level inside the

internal tank (only) is monitored/controlled by a float

switch mechanism (safety shut-off) self-activated

when the water level reaches a predetermined level,

causing the unit to stop/cease operation

automatically and the tanks will have to be emptied.

The fan motor will continue to operate. (this is

normal)

NOTE: The float switch mechanism (safety shut-

off) is activated/controlled by the water level

inside the (primary) internal water tank only.

NOTE:

• The quick connect fittings supplied with both

the main unit and external water tank are "self

sealing" connections.

• This means as soon as the quick connects

are "disconnected", water flow between the

main unit and external water tank

stops immediately.

External Water Tank Instructions:

1. Attach the water tank support tray (with

castors) to the saddle bracket located at the

rear (lower section) of the unit, using the

screws provided. See Fig. 35
