Installation
7.
When the previous steps are complete, turn the chiller on by placing the ON/OFF/SET
switch in the ON position. Immediately check for flow. If within five seconds no turbulence
is visible in the reservoir or the supply pressure gauge shows no pressure reading, shut the
chiller off by placing the ON/OFF/SET switch in the OFF position. If flow is established,
continue filling until fluid rises to within a few inches of the top of the reservoir. Do not allow
the reservoir to overflow.
8.
If the pump does not establish prime, disconnect the SUPPLY coolant line to vent any
trapped air, reconnect the line, and repeat step 7.
9.
If the pump still does not prime, use the following steps:
a.
Disconnect both coolant lines (have a container handy to catch any overflow from
the RETURN fitting).
b.
Force coolant into the SUPPLY fitting. The fluid will force the air out of the lines in
the chiller and out of the pump head, causing it to escape into the reservoir. Elevate
the coolant a few feet above the chiller, connect to the SUPPLY fitting, and let gravity
force the air out into the reservoir. Remember to have a container handy to catch
any overflow from the RETURN fitting.
c.
Reconnect the coolant lines and repeat step 7. Stop filling when the reservoir is full
to within a few inches of the top. Do not allow the reservoir to overflow.
A stainless steel mesh strainer attaches to the pump suction port near the bottom of the reservoir.
It can easily be removed for cleaning. First turn the pump off, then pull off the strainer, rinse it clean,
and push it back on. To protect the pump, routinely inspect the strainer to be sure it is clean and
properly attached. Hint: If the strainer is coated with debris, wrap it with a plastic sandwich bag
before pulling it off to prevent most of the debris from escaping into the reservoir. Failure to clean
a clogged strainer can restrict flow, causing the FAULT light to illuminate. Turn the chiller off for a
few seconds after correcting the condition to reset the alarm.
