Condensate Pump
An optional condensate pump is normally factory installed
with a 1/2 in. OD copper drain. The drain is stubbed outside
of the A/C unit cabinet for the installer to connect a drain
line to direct water away from the cabinet. The drain line
may be 1/2 in. ID vinyl tubing or a 1/2 in. OD copper to
copper sweat connection may be used.
See the installation drawing provided with your unit for
the location of the drain connection.
If an optional field installed condensate pump is used, it
must be positioned at the same level or below the level of
the A/C cabinet. The condensate drain pan is equipped
with a drain line inside the A/C cabinet. A p-trap is provided
on the end of the drain line.
Interconnect tubing must be field installed from the end of
the drain line to the inlet side of the condensate pump (see
).
Note:
Pour some water into the condensate drain pan
prior to start-up.
The condensate pump discharge line should be 1/2 inch ID
vinyl tubing or 1/2 inch O.D. (maximum) copper pipe to
prevent excessive back flow to the condensate pump
Figure 22.
Field Installed Condensate Pump
Humidifier
CyberAir systems utilize an electrode steam humidifier. A
water supply line for the humidifier must be connected to
the end of the copper tubing provided by the factory. Refer
to the installation drawing provided with your unit for the
size and location of the connection. The humidifier
requires normal tap water for the water supply. If the
supply water is high in particulate, an external filter may be
needed.
Important:
Do not use de-mineralized water.
Refer to the humidifier operator’s manual, supplied with
the equipment, for complete manufacturer’s information
on the humidifier and the supply water recommendations.
In most cases the humidifier empties into the condensate
drain line during the flush/drain cycle. Refer to the
installation drawing provided with your unit for the size
and location of the connection.
Utility Connections
Main Power
It is important that the unit nameplate be examined to
determine the operating voltage, frequency and phase of
the system (see
). The nameplate also
provides the full load amps (FLA), the current the unit will
draw under full design load, the minimum circuit ampacity
(MCA) for wire sizing, and the maximum fuse or HACR
(Heating, Air Conditioning, Refrigeration) breaker size
(MAX FUSE/CKT BKR) for circuit protection. The unit’s
nameplate is located inside the cabinet, within the
electrical box.
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury. All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state/national electrical codes.
NOTICE
Unit Damage!
Improper wire connections could result in damage to
the unit. Make sure the main power supply coincides
with the voltage, phase and frequency information
specified on the system nameplate. The supply voltage
measured at the unit MUST be within ±10% of the
voltage specified on the system nameplate.
