Other Direction Piping; Fixing The Indoor Unit Body; How To Connect Wiring To The Terminals - Haier H-MRV Series Service Manual

Other direction piping

Cut away, with a nipper, the lid for piping according to the piping direction and then
bend the pipe according to the position of wall hole. When bending, be careful not
to crash pipes.
Connect beforehand the indoor/outdoor electric cable, and then pull out the
connected to the heat insulation of connecting part specially.

5.Fixing the indoor unit body

Hang surely the unit body onto the upper notches of the
mounting plate. Move the body from side to verify its
secure fixing.
In order to fix the body onto the mounting plate, hold up
the body aslant from the underside and then put it down
perpendicularly.
Electric wiring
When connecting the cord before installing the indoor unit
Insert the cord from the back side of the unit, then pull it out on the front side.
Loosen the screws and insert the cord ends fully into terminal block, then
tighten the screws.
Pull the cord slightly to make sure the cords have been properly inserted and
tightened.
After the cord connection, never fail to fasten the connected cord with the
wiring cover.
Note: when connecting the cord, confirm the
terminal number of indoor and outdoor units
carefully. If wiring is not correct, proper operation
can not be carried out and will cause defect.
After connecting the piping, check the joints for gas leakage with gas leakage detector.

HOW TO CONNECT WIRING TO THE TERMINALS

A. For solid core wiring (or F-cable)(Fig.17A)
(1) Cut the wire with a wire cutter or wire-cutting pliers, then strip the insulation to about 25mm of
the exposed solid wire.
(2) Using a screwdriver, remove the terminal screw (s) on the terminal board.
(3) Using pliers, bend the solid wire to form a loop suitable for the terminal screw.
(4) Shape the loop wire properly, place it on the terminal board and tighten securely with the terminal
screw using a screw driver.
B. For strand wiring (Fig.17B)
(1) Cut the wire with a wire cutter or wire-cutting pliers, then strip the insulation to about 10mm of
the exposed strand wiring.
(2) Using a screwdriver, remove the terminal screw (s) on the terminal board.
(3) Using a round terminal fastener or pliers, securely clamp a round terminal to each stripped wire end.
(4) Position the round terminal wire, and replace and tighten the terminal screw using a screw driver.
