Read the instructions carefully and pay special attention to the warnings! Always check the tank cleaning machine before
operation.
3.2 Installation
Step 1
Always read the technical data thoroughly.
(See chapter 6 Technical Data)
Step 2
Assembly
Every Alfa Laval Gamajet is operationally tested before shipment and is ready to run after unpacking. No assembly is
required prior to use. The Alfa Laval GJ PF-FT has been configured to meet the operating conditions (at the Alfa Laval GJ
PF-FT, not at the pump) given to us, e.g. pressure, flow, temperature, cycle time, chemical adders, etc.
Note:
Any change to the original operating conditions will affect the Alfa Laval GJ PF-FT accordingly.
Warning: Do not force Tee Housing (Pos. 8) to rotate. Doing so may cause damage to the internal components.
Step 3
Inlet Connections
The standard inlet connections for the Alfa Laval GJ PF-FT are a 1-
1/2” slip-fit or a 1-1/2” Tri-Clover. Others inlets are
available. It is recommended that when using the pipe 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 PF-FT, make sure the supply line has been adequately flushed. It can be mounted on a
rigid 1-
1/2” pipe using appropriate mounting methods. In most applications, the machine will be mounted with the inlet
connection pointing up; however, the Alfa Laval GJ PF-FT will function at any orientation.
The Alfa Laval GJ PF-FT can be suspended from the top of the tank via a flexible hose. The dual nozzle machine is designed
to have balanced forces in order to keep it centered even while hanging. We do not, however, recommend attaching the
machine to a flexible hose while in the inverted or horizontal orientation. This form of mounting is not rigid and, thus, will not
maintain the machine
’s position in the tank.
Warning: When attaching the Alfa Laval GJ PF-FT onto the supply pipe, ALWAYS apply the wrench to the Sanitary
Inlet (11) at the top/inlet of the unit. Never use a wrench on the Stem (7), Tee Housing (8), or Tee Housing
Cap (14) to tighten the unit onto the pipe. Doing so risks internally damaging the machine.
Step 5
Location inside Tank
Generally, a single Alfa Laval GJ PF-FT will be positioned in the approximate center of the vessel in order to equalize the
cleaning radius in all directions. Some vessels, however, may have specific cleaning problems such as coils or heavy
deposits such as the liquid level line (bathtub ring). In these situations, the Alfa Laval GJ PF-FT should be located closer to
the difficult area for the best cleaning results.
Tanks with internal mechanisms or structures such as an agitator shaft, impellers or baffles will require careful positioning to
minimize the “shadow” on areas which do not receive direct jet impact. Sometimes, more than one machine, or, more than
one placement of a single machine,
may be necessary to avoid shadow problems or “striping.”
