Contents The cylinder is a purpose designed unvented water

heater. The unit has a stainless steel inner vessel,

which ensures an excellent standard of corrosion

resistance. The outer casing is a combination of

resilient thermoplastic mouldings and plastic coated

corrosion proofed steel sheet. All products are insulated

with CFC free polyurethane foam to give good heat

loss performance.

The unit is supplied complete with all the necessary

safety and control devices needed to allow connection

to the cold water mains. All these components are

preset and not adjustable.

This appliance complies with the requirements of the

CE marking directive and is Kiwa approved to show

compliance with Building Regulations (Section G3).

The following instructions are o󰀨ered as a guide to

installation which must be carried out by a competent

Notes:

12 - Temperature sensor - 10 m long (supplied with Baxi HP40/HP50 Monobloc Heat Pump)

VC - Diverter valve - 28 mm connections (supplied with Baxi ASHP Cylinder)

Important

A temperature sensor and T5 adaptor (part no. 7750595) are required to enable the kit to operate correctly and to

connect the sensor to the PCB. One each of the sensor and T5 adaptor are supplied with the heat pump. If these are

already being used for another of the products functions please order part no. 7750595.

Fig. 1: Hydraulic Schematic.

Warning

The schematics below are based on the Baxi HP40/HP50 Monobloc Heat Pump range. See manufacturers

instructions on how to connect the cylinder wiring to other heat pumps to ensure shut down of all heat sources in

the event of a thermal cut out on the cylinder.

Notes: DHW sensor connection:

1. Identify the output from the heat pump - CN13 on PCB “A” Main Control Board Hydraulic.

2. Route the domestic hot water sensor cable via the low voltage cable feedthrough on the heat pump.

3. Fit the sensor connector onto the T5 adaptor.

4. Insert the sensor into the overheat thermostat pocket.

Notes: Diverter valve connection:

1. Identify the output from the heat pump - CN11 connections 5 & 6 (N=16) on PCB “A” Main Control Board Hydraulic.

2. Route the valve power cable via the high voltage cable feedthrough on the heat pump.

3. Connect the valve power cable to PCB “A” Main Control Board Hydraulic.

Power supply

From A1 From A2

Connection of the immersion backup heater cable

depends on the application. Only when the cylinder is

installed will this wiring be needed. The unit only sends

an on/o󰀨 signal to the backup heater. An additional

contactor is supplied and a dedicated terminal is needed

to supply power to the backup heater.

The 25 A contactor supplied with the cylinder is ONLY

suitable for switching the 3 kW immersion heater in the

cylinder. Ensure that the cable is xed and the strain

relief is used.

Procedure

• Connect the cable to the appropriate terminals as

shown to connections 13 and 16.

• To prevent strain on the cable secure it with cable

ties to the cable tie mountings.
