Read the instructions carefully and pay special attention to the warnings! Always check the tank cleaning
machine before operation.
4.2 Installation
Step 1
Always
read the technical data thoroughly.
(See chapter 7 Technical Data)
Step 2
Assembly
Every Alfa Laval GJ is operationally tested before shipment and is ready to run after unpacking. No assembly is required prior
to use. The Alfa Laval GJ 18 has been configured to meet the operating conditions (at the tank cleaning device, not at the
pump) specified at the time of sale, e.g. pressure, flow, temperature, cycle time, chemical adders, etc.
Note: Any change to the original operating conditions will affect the Alfa Laval GJ 18 accordingly.
Warning: Do not manually force the Tee Housing (pos. 24.1) to rotate. Doing so may cause damage to
the internal components.
Step 3
Inlet Connections
The standard inlet connection for the Alfa Laval GJ 18 is a 2 ½” NPT female adapter. It is recommended that when connecting
the unit to the supply hose thread, the mating male thread should be wrapped with PTFE pipe joint tape prior to mounting. This
will minimize any chance of leakage and will make subsequent removal much easier.
Step 4
Mounting
Before mounting the Alfa Laval GJ 18, make sure the supply line has been adequately flushed. It can be mounted on a rigid 2
½” pipe using a pipe wrench. The Alfa Laval GJ 18 operates most reliably when mounted with the inlet connection pointing up;
however, the unit can function in any orientation.
The Alfa Laval GJ 18 can be suspended from the top of the tank via a flexible hose. The machine is designed to have balanced
forces in order to keep it centered even while hanging. A flexible hose should not be used, however, when using the machine
in any other orientation since the non-rigid hose will not maintain the unit’s position in the tank.
Warning: When attaching the Alfa Laval GJ 18 onto the supply pipe, ALWAYS apply the wrench to the Inlet Collar
(pos. 1) at the top/inlet of the unit. Never use a wrench on the Stem (pos. 15.1), Tee Housing (pos. 24.1), or
Tee Housing Base (pos. 30) to tighten the unit onto the pipe. Doing so risks internally damaging the
machine. Refer to Step 1 in chapter 6.1 General Maintenance.
