2.3 WATER SUPPLY CONNECTION
A. The automatic water supply make-up system continually monitors
the reservoir tank and fills it when needed. Connect as follows:
1.
2.
3.
2.4 AIR COOLED CONDENSER
A. Air cooled condensers require
ambient air temperatures between
60°F and 95°F for efficient
operation. Operating above above
95°F may result in elevated
condensing pressures and eventual
shut-down on the high pressure
safety switch. In such cases, a water
assist unit may be necessary for
operations. Air temperatures below
60°F may result in below normal
condensing pressures and poor
condensing. In such cases, a low-
ambient damper assembly is
required. Check with the
ADVANTAGE service department for
more information on operating with
ambients air temperatures above
95°F or below 60°F.
B. Air flow is generated by the motor
mounted fans (figure 2.4A) or
centrifugal blowers (figure 2.4B). Air
flow is from the outside of the
chiller, through the condenser and
exhausted through the top of the
unit. On centrifugal blowers models, exhaust air can be ducted
outside of the plant's interior environment. Special duct work is
required and a HVAC contractor should be consulted for sizing and
material specifications. Exhaust air can not be ducted on motor
mounted fan models.
C. A free air space of at least two (2) feet is required at the condenser
intake and six (6) feet at the condenser discharge to allow for
proper air flow.
Connect the chiller's 'WATER SUPPLY' port to the plant's
city water source.
Minimum water supply pressure requirement is identified
on the equipment data plate. This is normally 20 psi.
Be certain to use a water supply line equipped with a back
flow prevention device to prevent contamination of potable
water.
