2 ZONE KIT

PAC-TZ02-E

WARNING

●

INSTALLATION MANUAL

If Cylinder unit (Hydrobox) has already been connected to the power supply, ensure circuit breaker is off before carrying out

electrical work.

If the 2 zone kit is installed incorrectly or modified after installation by the user, water may leak or 2 zone kit may fall from

Cylinder unit or wall.

All installation should be performed by a qualified technician according to local regulations and the instructions given in this

manual.

Connections must be made securely and without tension on the terminals.

CAUTION

●

●The 2 zone kit must be installed by 2 or more people.

All exposed water pipework should be insulated to prevent unnecessary heat loss and condensation.

To also use the 2 zone kit in Cooling mode, securely apply heat-insulation to draining pipework. If heat-insulation is

inadequate, condensation could occur on the surface of pipes and dew could drop on the floor or important goods.

To prevent dirty water from draining onto the floor next to Cylinder unit or under Hydrobox, please connect appropriate

discharge pipework from the 2 zone kit to its disposal location.

Secure 2 zone kit to prevent it from falling.

Do not hold piping or drain socket when moving the 2 zone kit.

Avoid the connection of piping or drain socket from damage. Otherwise, it may cause water leakage.

To prevent incorrect installation, please connect the flexible hose at the bend radius of 150 mm or more.

The water flow rate between the Cylinder unit (Hydrobox) and the 2 zone kit must be greater than the total flow rate of Zone1

and Zone2. Otherwise, Zone1 and Zone2 may not be heated properly.

● This 2 zone kit MUST be used with Cylinder unit or Hydrobox except for E*SE models.

●

Before starting installation, read the following description together with the installation manual included with the Cylinder unit (Hydrobox).

● Please read carefully and observe fully the following safety precautions.

Precaution that must be observed to prevent injuries or death.

WARNING

After installation, carry out a test run to ensure correct operation, then explain operation method and safety precautions to the

end user.

Tell your customers to keep this installation manual, and when they give or sell this machine to any other person include this

installation manual with it.

●

Incorrect handling could lead to injury or damage to house and household articles.

This symbol mark is according to the directive 2012/19/EU Article 14 Information for users and Annex IX, and/

or to the directive 2006/66/EC Article 20 Information for end-users and Annex II.

Your Mitsubishi Electric heating system products have been manufactured with high quality materials and components

which can be recycled and/or reused. The symbol in Figure 1.1 means that electrical and electronic equipment, batter-

ies and accumulators at the end of their life, should be disposed of separately from your household waste.

If a chemical symbol is printed beneath the symbol (Figure 1.1), this chemical symbol means that the battery or accu-

mulator contains a heavy metal at a certain concentration. This is indicated as follows;

Hg: mercury (0.0005%), Cd: cadmium (0.002%), Pb: lead (0.004%)

In the European Union there are separate collection systems for used electrical and electronic products, batteries and

accumulators.

Please dispose of this equipment, batteries and accumulators correctly at your local community waste collection/recy-

cling centre.

Contact your local Mitsubishi Electric dealer for country-specic details on disposal.

Please, help us to conserve the environment we live in.

NOTE

● Please use PVC pipe for drain piping.

● Use only compatible adhesive/glue for pipe joint.

● For proper drain-off, install pipework with gradient/fall of min. 1/100.

● Install pipe to fall continuously without bowing.

● Do not install any air purge points on condensate drain pipe run.

● Condensate drain pipe must discharge to suitable and safe outlet location. It should not be directly connected to any

sewer-connected pipework that may introduce sulphurous gases/smells to the building.

* “VP-20” is a PVC pipe with an outside diameter of 26 mm and an inside diameter of 20 mm.

Field supplied drain pipe

(VP-20A)* (Insulated)

Connect drain socket to field pipeworks

using suitable adhesive bond.

Connect the drain pipe only for Heating/Cooling models.

Pump setting selection

PP: Proportional Pressure

You can check the setting by pressing the push button.

If you press the button for 2 to 10 seconds, the user interface switches to “setting selection” if the user interface is unlocked.

You can change the settings as below table.

The head (pressure) is reduced at falling heat demand and increased at rising heat demand.

PP1: lowest proportional pressure curve

PP2: intermediate proportional pressure curve

PP3: highest proportional pressure curve

PP Auto Adapt: highest to lowest proportional pressure curve

The Auto Adapt function enables the circulator to adjust the pump performance

automatically to the size of the system or the variations in load over time.
