Chiller installation
1. Make sure the chiller is placed on a firm, level surface in a location that has plenty of ventilation
and will not be exposed to salt or saltwater. Do not use an extension cord for the chiller or the
thermostat.
The requirements for ventilation are
a) Back portion: Condenser (radiator) requires at least 10" clearance to allow air into the
chiller.
b) Front portion: Requires at least 15" clearance to allow for proper air flow.
c) Chiller must not be placed in a closed closet or cabinet.
d) The warm air from the chiller must be completely evacuated from the chiller location. A fan may
be necessary to draw warm air away from the chiller. The maximum operating temperature is
95° F.
2. The Prime chiller can be plumbed with either rigid PVC or vinyl tubing connected to an external
or submersible pump (not included). Use 3/4" ID (inside diameter) or larger pipe/tubing for
all plumbing connections.
3. The inlet and outlet are located on opposite sides of one another (See diagram below).
Either port can be used as the inlet or outlet depending upon the location of the chiller
and plumbing configuration. The ports will accept 1" male pipe thread (MPT) fittings for
plumbing with rigid PVC. You may also use the enclosed barbed fittings for plumbing with
vinyl tubing. Use Teflon tape for all threaded fittings.
4.
It is strongly recommended to use unions and ballvalves connected to the inlet and
outlet for maintenance and servicing.
5. For the most efficient control over the aquarium's temperature, it is recommended that the
chiller be plumbed so that it is the last component before water returns back to the tank. If
other devices, such as a mechanical filter, precede the chiller, make sure the flow rate going
through the chiller still meets the minimum flow rate requirement.
6. Once you have finished plumbing the chiller it is recommended that you circulate water
through the chiller and plumbing for at least 30 minutes to ensure adequate water flow and
no leaks.
7. Tilt the chiller from the back to allow any trapped air to escape from the evaporator housing.
You may need to do this a few times until all of the air has escaped.
