1. Introduction Glossary of terms The following abbreviations and terms are used thorough the document and refer to the following: Beermaster Free Cooler BMIEP Beermaster Indoor Evaporator Plus (also referred to as the evaporator) BMOP Beermaster Outdoor Plus (also referred to as the Condensing Unit Full Load Current High Pressure Low Pressure...
During installation & maintenance Ensure that: The units are installed and maintained by qualified personnel only. The electrical supply is isolated and secured from accidental re-connection whilst work is carried out on the equipment. Electrical connections to the unit should be made in accordance with IET regulations as well as local laws and legislation. Interconnecting pipework Interconnecting refrigerant lines installed between the condensing unit and evaporator must be purged through with oxygen-free nitrogen to remove any particles of dirt, debris or moisture, in accordance with good refrigeration practice.
How to gain access to the condensing units Loosen and remove all screws on the roof of the unit. Remove and put aside the roof panel. Loosen and remove all screws on the front two access panels. Remove the front panel. Rotate and slide the two side covers off the unit.
Positioning the evaporator The evaporator has a “draw-through” airflow direction and is designed for either ceiling mounting or wall mounting. For wall mounting, the wall mounting kit (optional) must be used and is supplied as a separate order. Locate the evaporator in accordance with the minimum clearances as detailed below: 150 mm 150 mm Air Clearance...

How to gain access to the condensing units To gain access to the solenoid, filter and TEV, the end covers To gain access to the controls and enable the installation will need to be removed. This can be done by loosening and of the mains cable.
3. Installing the units Mounting the evaporator unit on a wall bracket Mounting the condensing unit on a (Wolseley pt. no. 684222) wall bracket (Wolseley pt. no. 684222) • Check the intended wall is strong enough to support the total operational weight of the unit, including the refrigerant charge.
Evaporator bracket centres 4. Pipe sizing Pipework runs up to a maximum of 30m (total equivalent length) are recommend between the BMOP and BMIEP units. Each instal- lation must be evaluated for the total equivalent pipe run length, including equivalent lengths for bends, additional fittings and vertical lifts etc.
5. Pipework installation - supports and routing Pipework to and from the units should be selected to suit the application and not the connection size of the unit. Pipework should be supported independently from the condensing unit and evaporator in a way that prevents the transmission of vibration between the units.
7. Expansion valve phial location A suitably sized thermostatic expansion valve (TEV) is fitted to the evaporator with an external equalizing line fitted to the suction header. The expansion valve capillary line must be coiled but must not be clamped to the suction line pipework. The expansion valve should be fitted to the suction stub once the interconnecting pipework has been installed.
9. Electrical supply & function CAUTION: Both the condensing unit and evaporator should be fed from the same electrical supply. If this is not possible, it is important to ensure that the electrical supplies are from the same phase. Failure to do so will result in a potential of 415 Volts between the units.
11. Power entry to the evaporators The power entry points are on the back-left hand side of the evaporator, as shown circled below. The cable should be suitably secured in a gland and earthed to the stud provided. The supply L & N cable cores should be routed into the control box via the conical grommet, as shown circled below.
12. Pressure testing Pressure leak test Both condenser and evaporator units have been strength & leak tested, dehydrated and filled with a holding charge of “dry air” during manufacture. After installation, the entire system should be leak tested before evacuation as follows: •...
HIGH SIDE LOW SIDE Condensing 43° Evaporating 2°C Dew Air On 32° Air On 10°C When the system is correctly charged, the sight glass should be almost free of bubbles and there should be an adequate (5- 6K) superheat at the compressor suction. Once the system is fully charged, check for stable conditions. The superheat for the BMIEP evaporator expansion valve is factory set to 5K (approx.).
16. Commissioning Final checks Prior to starting the system, final checks should be made to the wiring, ensuring all connections are correct and tight. Before operating the units, check that all guards, motors, mountings and electrical covers are secure, and that all necessary terminal block links are added/removed and that fans rotate freely.

HP/LP switches The condensing unit HP and LP switches are located in the right-hand end of the housing. The device has been pre-set to the conditions specified below. Low pressure setting On the suction side of the compressor, the low pressure settings stop the compressor when the pressure gets too low (lower set-point) and restarts the compressor once the pressure has risen back to the upper set-point.

Isolation The isolator for the BMOP can be found behide the isolator cover. Note this will only isolate the condensing unit, not the evaporator. It is the installer‘s responsibility to decide to fit the cover or leave uncovered. If the isolation cover is used then potentially an auxiliary emergency stop may need to be incorporated as part of the installation.
The BMIEP controller has a setpoint operating range of 4 to 32°C (Normal operation range 10-13°C.) For operating temperatures below 8°C, a defrost sensor should be fitted (Wolseley pt. no. 684226). For more information on this, please see the section below on defrost.

Controller alarm output & fault signals If the cellar temperature is outside the acceptable range of -1 or +2°C from the set point temperature for 30 minutes, the alarm will be initiated. The alarm will automatically reset once the cellar temperature is back within this acceptable control band. A 12 vdc relay can be connected between the Alarm signal and the ‘+12 vdc’...

Operation modes As well as energy saving mode, the BMIEP controller has two different speed options. This means that the fan can be set at lower speeds to reduce the noise, if necessary. The default speed option has a fan speed of 1600rpm when cooling is on and 1200rpm when cooling is off.

Free cooler There is an additional option to use a free air cooler (BFC) to reduce energy consumptions. If a BFC is to be installed as part of the system, the free option mode needs to be enabled. This is achieved by moving the free cooler jumper to the YES position (left hand position).

Maintenance Warning: the unit must be electrically isolated before maintenance work is undertaken The following routine maintenance is required: Every 3-6 months The condenser should be cleaned to ensure correct operation of the condensing unit. If the condenser coil is obstructed by dirt or rubbish, the unit will experience high condensing temperatures which will result in higher running costs, loss of compressor efficiency and, ultimately, overheating of the compressor and/or condenser fans.
