2.4 MAKE-UP WATER SUPPLY CONNECTION
A.
The automatic water make-up system continually monitors the
reservoir tank and fills it when needed. Connect as follows:
1.
Using appropriately rated hose or fluid piping connect the
“water make-up” connection to the plant’s water source.
2.
Minimum make-up water supply pressure is normally 20 psi.
3.
Install an owner supplied shut off valve in the
make-up water supply line. Install this valve on
the outside of the unit.
4.
Use a back flow prevention device as may be
required by local codes to prevent possible
contamination of potable water.
B.
Do not use automatic water make-up system when
operating with glycol below 48°F.
2.5 AIR COOLED CONDENSER
A.
Air-cooled condensers require ambient air temperatures
between 60°F and 95°F for efficient operation. Operating
above 95°F may result in elevated condensing pressures
and eventual shut-down on the high pressure limit
switch. Air temperatures below 60°F may result in
over condensing pressures and cause a low pressure
refrigerant fault. Consult with the Manufacturer’s 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 or
centrifugal blowers. 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.
