6.1.

  When  larger  volumes  of  water  are  required  than  can  be  provided  by  one 

heater, multiple installation can be made by connecting a number of heaters in 
PARALLEL of the cold feed manifold (See Figure 6). This is the ONLY method that 
is recommended. DO NOT plumb these heaters in series.

6.2.

  To  set  the  heaters  in  this  arrangement  use  the  appropriate  procedure  as 

described previously. Each heater in parallel must be set individually.

6.3.

 In this application restrictors capable of closing flow completely should be used 

so that as each heater is set in turn, the other heaters in the installation may be 
isolated.

NOTE -

 In this application it is advisable especially where low flow rates exist to 

plumb the cold manifold in 7/8" pipe with 5/8"pipe spurs to each heater.*Not

This  unit  does  not  require  an  Pressure  Relief  Valve  by  UL  standard,  it  is 
recomended that you check with the local codes to find out whether this is required. 
If one is required please refer to Figure 6. 

YOUR MAREY POWER PACK SHOULD GIVE TROUBLE FREE OPERATION, 
HOWEVER SHOULD A FAULT OCCUR THE TABLE BELOW SHOULD ALLOW 
MOST  FAULTS  TO  BE  IDENTIFIED.  FAULT  FINDING  SHOULD  ONLY  BE 
CARRIED OUT BY A COMPETENT PERSON.

SYMPTOM

POSSIBLE CAUSE

REMEDY

1.

 Water too hot.

A.

 Water flow too low.

Increase the flow by turning the water control.

A.

 Electrical power to

the power pack heater
is off.

Ensure that the electronics to the power pack
is switched on the neon is lit.

B.

 Water flow too high. Reduce the flow  by turning the water control.

C.

 Element fault.

Check for open  circuit.

2.

 Water too cold.

3.

 Temperature

varies while
showering,
cycling
hot/cold.

A.

 Pressure switch is

operating, normally
making a click as it 
does so.

Water pressure/flow issue.

B.

 Input pressure is

below 1.0 bar (14.5 psi)
flow is not stable.

Ensure that your stop cock and servicing valve
are opened fully.

4.

 Power on

indicator not lit.
Isolating switch 
ON but its neon
not lit.

A.

 Cartridge fuse or

miniture circuit breaker

consumer unit) or
switch fuse.

Switch off shower and isolating switch.
Renew fuse, reset the mcb. If they operate
a second time, contact a qualified electrician.

B.

 Residual current

device (rcd) or (earth
leakage circuit breaker)
has operated.

Follow the same procedure as above. If this
has happened with a split load consumer unit
on initial installation, check that the neutral core
of the power pak feed cable is connected to the
protected neutral bar of the unit.

5.

 Water emerges

from pressure
relief valve.

A.

 PRV has operated.
