External Water Tank Feature:
This unit is equipped with a secondary “External
Water Tank” feature. (tank quick connect to be
installed by customer)
The main unit is inclusive of a factory installed
“quick connect” fitting located at the rear of the unit.
When the external tank is connected to the main
unit, it will increase total running time/operation
(air conditioner & dehumidifying modes only) up-to
approximately 12 hours (depending on relative
humidity conditions) utilizing both tanks.
It is possible to operate this unit utilizing the
“Internal” (primary) water tank only. (However,
running time/operation will be reduced) If the
external water tank is not connected to the main
unit, water flow will be automatically directed
into the internal water tank.
During air conditioner & dehumidifying modes,
(external tank attached) 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 (first) into the
(secondary) external water tank. When the water
level inside the external tank reaches a
predetermined level, the water flow is reversed and
re-directed into the (primary) internal water tank.
The water level inside the internal tank 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 (air conditioning/dehumidifying)
operation automatically. 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.
If the external water tank is not connected to the
main unit, water flow is automatically directed inside
the internal water tank.
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
factory installed castor) to the (2) saddle
brackets located at the rear (lower section)
of the unit, using the screws provided.
See Fig. 35
IMPORTANT NOTE: In the event the
original screws supplied with the unit are
misplaced and to avoid damage to the
sealed (cooling) system, never use
replacement screws longer
than 16mm (5/8)
2. Remove the (male) quick connect fitting
located inside the external water tank
and attach it to the female receptacle/port
at the rear of the external tank, tighten
moderately. See Fig. 36
