KL50555 RAPT Bluetooth Glycol Chiller | Initial Setup & Assembly

If Glycol Chiller has been moved/delivered do not turn it on unless it has been standing upright for at least 24 hours. Failure to do this will void warranty and may damage the unit. Leave the Glycol Chiller upright for at least 24 hours before plugging in mains power after receiving and unboxing

Ensure there is at least 100mm of clearance on each side of the Glycol Chiller (excluding front) to allow adequate airflow. Failure to allow adequate ventilation will reduce performance, increase power consumption and void warranty

This Glycol Chiller is not intended for cooling wort from boiling or temperatures above 50°C. Using the chiller to cool liquids above 50°C can overload the compressor and will void warranty

Do not run the pumps dry or allow the reservoir to ice over. Ensure the pumps are always submerged when in operation. Running the pumps dry or increased resistance due to ice formation can damage the pumps.

Whenever the glycol chiller is operating and cooling the reservoir the pumps should be operating to keep the liquid in the reservoir agitated and avoid ice formation

Replace propylene glycol solution every 12 months to avoid potential damage to pumps, lines or reservoir

Before Installation

1. Let the glycol chiller sit for at least 24 hours after delivery or after sitting on its side before turning the unit on

2. Ensure there is adequate ventilation (at least 100mm on each side of the glycol chiller, excluding the front)

3. Check for any signs of damage which may have occurred during shipping

1

Install the Return Line JoinTech fittings

Install 2 x male JoinTech fittings in the return sockets (marked with a red dot) using the supplied washers and nut

Locate the two red Return Lines. These are pre-fitted with a barb with 1/2" thread. Thread these onto the male thread of the JoinTech as shown

The nuts can be tightened by hand or with a wrench. As they are plastic fittings be careful to not overtighten

2

Install the Outlet Line JoinTech fittings

Install 2 x male JoinTech fittings in the outlet sockets (marked with a blue dot) using the supplied washers and nut

Thread one of the supplied 1/2" thread barb onto each JoinTech once installed, as shown

Push one end of each of the blue Dual Outlet tubing over the barbs and secure each end of the blue Outlet tubing with one of the supplied hose clamps

The nuts can be tightened by hand or with a wrench. As they are plastic fittings be careful to not overtighten

Inlet and outlet lines installed

3

Connect the Outlet line to the Submersible Pump

Identify the inlet and the outlet of the supplied submersible pump

Connect the blue Outlet line to the outlet barb of the pump. Secure the connection with the included hose clamp as shown

4

Route the power lead of the Submersible Pump

On the left hand side of the RAPT Glycol Bluetooth Chiller is a cutout to allow for neat cable routing for the power lead of the submersible pump

Lift the lid of the chiller. This exposes two screws that secure the top in place

Remove each screw with a Phillips head screwdriver

Lift the top lid carefully to allow the submersible pump lead to be routed to the left hand side of the RAPT Glycol Bluetooth Chiller as shown

The RAPT Bluetooth Glycol Chiller is now assembled and ready to connect to a controller and fermenter
