Ai C20 RECIRCULATING CHILLER USER’S MANUAL

English
It is necessary for 2-3 people to assist in uncrating this unit. Crated unit can weigh between 100 Lbs. and
can be a little heavy for one person. Remember your safety is our concern so please use all the safety
equipment to move the crate such as a pallet jack and good gloves. When uncrating the unit, remove the
bottom screws of crate and pull the crate up, remembering that 2-3 people will need to help. Next remove
all foam and any plastic bags that come with unit.
Unit must be installed 3 feet away from any walls or partitions for easy access of main power switch.
Maintain ambient temperature below 75 °F (24 °C).
Place the chiller on a flat, leveled surface.
In case the chiller is delivered sideways, put the chiller up right and let it sit for 24 hours before turning the
unit on.
Always use insulated tubing for the chilling fluid connection. Connect the insulated tubing from the chiller
coolant inlet and outlet port to the inlet and outlet ports on the device being chilled. (Refer to figure 1).
If heating temperature is higher than 80°C, allow one inch of top space in the reservoir when adding fluid,
to allow fluid heat expansion.
Coolant:
• If the chilling temperature is between 10 °C and -20 °C, we recommend using a mix of 50% ethylene
glycol + 50% distilled water (See table 1 below for ethylene glycol parentage freezing point)
• If the chilling temperature is 10 °C or higher, we recommend distilled water.
• Do not use salted water (NaCl/H2O or CaCl2/H2O)
Table 1:
IMPORTANT! -20°C/-4°F ULTIMATE TEMPERATURES ARE TESTED UNDER EMPTY LOAD CONDITION (NO
ROTARY EVAPORATORS CONNECTED).
