Water Piping<br />
As with any water system, it is important that the system<br />
be clean. The pipe work installer must remove weld scale,<br />
rust and contamination during pipe work fabrication.<br />
The system water piping must be fl ushed thoroughly<br />
with recommended alkaline fl ush or other chemicals that<br />
are compatible with 316 stainless steel prior to making<br />
connections to the <strong>ClimaCool</strong> chiller. There are certain<br />
necessary components that should always be installed in<br />
the chilled water system. (See Figures 1 and 2 on page 13 -<br />
Water Piping Confi gurations for confi gurations with multiple<br />
modules). All water piping must be installed in accordance<br />
with applicable codes and standards.<br />
Temperature Sensor and Wells<br />
<strong>ClimaCool</strong> provides (2) temperature sensors and wells with<br />
each chiller system confi gured by the CoolLogic Control<br />
System. They must be fi eld installed 36” - 60” away from the<br />
bank and before the strainer on the chilled water inlet and<br />
chilled water outlet (See Water Piping Confi gurations – page<br />
13). Sensors must be fully inserted into the well to obtain<br />
proper readings.<br />
Pressure Diff erential Flow Sensor or Switch<br />
It is imperative that minimum and maximum water fl ow<br />
rates, as defi ned in the Physical Data tables on page 6,<br />
are not exceeded. To prevent the operation of the chiller<br />
without suffi cient water fl ow to the evaporator it is a<br />
required safety device to install a pressure diff erential fl ow<br />
sensor or switch in the chilled water circuit, downstream of<br />
the strainer (See Water Piping Confi gurations – page 13).<br />

Pressure Taps<br />
The installing contractor must provide access ports for<br />
connecting the pressure diff erential fl ow sensor or switch<br />
and pressure gauges for the chilled water system. A 1/4”<br />
pressure tap is required on the inlet and the outlet of the<br />
chilled water system for a total of four taps. If a port is<br />
shared by the pressure diff erential fl ow sensor or switch and<br />
the pressure gauge it will require two 1/2” taps. (See Water<br />
Piping Confi gurations – page 13).<br />
Water Isolation Valves<br />
It is recommended to provide bank water isolation valves for<br />
proper isolation and maintenance of the chiller, pump and<br />
strainer (See Water Piping Confi gurations – page 13).<br />
Strainers – Minimum 60 Mesh Screen Required<br />
<strong>ClimaCool</strong> chillers utilize brazed plate heat exchangers<br />
which are extremely sensitive to debris. Therefore, it is<br />
mandatory that all chilled water systems include a strainer<br />
with a minimum of 60 mesh screen for proper fi ltration at<br />
all times when the chiller is operating. The strainers must<br />
be installed as shown in the Water Piping Confi gurations on<br />
page 13.<br />
<strong>ClimaCool</strong>’s warranty does not cover and does not apply to<br />
products which have defects or damages due to freezing<br />
of the water supply, an inadequate or interrupted water<br />
supply, corrosives or abrasives in the water supply, or<br />
improper or inadequate fi ltration or treatment of the<br />
water supply.<br />
