7. Reconstruction method. (from side flow to down flow)
(FOR MRT080 – 200A/AR ONLY)
Series MRT side flow units are able to modified to down flow at field.
But you need to prepare some accessory parts.
If you will modify to down flow, you prepare accessory parts and reconstruct below method.
4. Lifting Method.
When the unit is to be lifted and moved, attach ropes to the suspension plates (4
p.c.s) provided on the top of the unit.
When the unit is lifted, it is center of gravity tends to shift the unit one side and so
balance, such as that in the figure below, should be attained. The angles at which
the ropes suspend the unit should be at least 60° at the compressor end and at
least 45 ° at the condenser end.
Care should be taken to avoid contact with the main unit while carrying.
5. Drain Piping.
(1) The condensate drain fitting (R 1) is provided. The drain pipe can be led out at
the right or left side. Under standard specifications, it is led out at the left side
and the right side is covered.
(2) The drain pipe must be provided with a trap on the outside of the unit and also
installed at an incline for proper drainage, as shown below.
(3) To prevent condensate formation and leakage, provide the drain pipe with
insulation to safeguard against sweating.
(4) Upon completion of the piping work, check that there is no leakage and that
the water drains off properly.
6. Refrigerant Charge
An additional charge is unnecessary.
The table below shows the amount of the charge when the factory is shipped
.
Hook (as directly aligned
over the center of gravity
as possible
The drain piping should have a drain trap.
